Business spotlight: Canvas robot revolutionizing drywall installation

San Francisco-based construction robotics firm Canvas offers a robot drywall finisher that replaces a professional drywaller. Seeing savings for customers and increasing their sales, large contractors and materials suppliers have partnered with the 7-year-old startup.

Founders’ mechanical engineering backgrounds

Canvas’ drywall finishing robot was born from the extensive robotics background of its co-founders, CEO Kevin Albert and CTO Maria Telleria. They hold a master’s degree and a Ph.D. in mechanical engineering from the Massachusetts Institute of Technology (MIT), respectively.

Albert has 20 years of experience in robotics. Telleria is the lead author on eight patents and five patent applications for Canvas systems and is co-inventor on three other patents related to pneumatic robots.

Launched in 2017, Canvas’s technology is intended to mechanize the craft skill of drywall finishing by systematizing how a wall is sprayed and sanded to create a seamless finish. The tool is designed to help contractors complete projects faster, more economically, and with assembly line-type precision.

“Canvas was founded with the motivation to bring advanced robotic tools to construction,” said Telleria. “We are passionate about creating new tools that protect workers from repetitive work, dust exposure, and risk of working at heights.”

Unlike many tech tools for construction, this one was partly informed by Albert’s work in construction in high school and college, as well as the expertise of longtime construction professionals who have helped in the technology’s development.

“Kevin did some construction work in high school and college, so he is aware of how hard it can be on the body. But we also knew that we needed experts to create a robotic solution that really met the needs of the taper. So early on, we brought on both advisors and employees who had construction experience,” Telleria said.

How Canvas works

The Canvas robot uses computer vision and Artificial Intelligence (AI) to recognize different seam and wall types. Operated by a worker, the robot enables workers to produce predictable and consistent finishes in a fraction of the time it takes for a worker to do so manually. The machine also makes the work safer for workers, removing 99% of the dust created with drywall work.

Efficiency is another place the robot shines, enabling workers to finish more drywall in less time without being physically worn out. Repetitive movements in construction, like completing overhead tasks for long periods of time, can lead to physical strain and, sometimes, serious injuries.

For those unfamiliar with drywall finishing, it’s some of the most physically demanding work in construction. It is also dusty and often hot work. The finishing process is itself a semi-craft, requiring a skilled worker to tape, spackle, and sand the seams, ensuring the finish is clean and consistent.

It’s not intended for amateurs, but Canvas’ robots easily tackle the work.

“Our robotic systems have mm-level precision. Most importantly, they produce consistent results,” Telleria said.

Having a robot that can provide Level 4 or 5 finishes without error, as Canvas does, could be a great time- and back-saver for contractors.

Growing corporate partnerships

Industry leaders have embraced canvas technology in contracting, materials supply, and manufacturing. In March 2023, Canvas announced that equipment manufacturer Hilti would produce its robotic machines.

In May 2023, Canvas partnered with USG Corp., a well-known American manufacturer of drywall and other construction materials.

“The partnership leverages two major technical advances: onsite robotics from Canvas and advanced building materials expertise from USG.,” a USG press release said. “These organizations joined forces to collectively innovate and address chronic labor shortages, schedule and budget overruns, quality inconsistencies, and productivity and safety issues that have continuously challenged the drywall industry.”

The partnership enables Canvas to further refine its technology to produce the best customer results.

“The Canvas materials process team has been working with USG for more than a year to enable high-quality surface finishing with current materials and are developing next-generation materials,” said Dr. Srinivas Veeramasuneni, Chief Technology Officer, USG.

In 2022, Daley’s Drywall & Taping, Inc. and Nevell Group Inc. both signed multi-machine, multi-year leases for priority access to the Canvas technology. Since then, the wall and ceiling contractors have operated Canvas robots on their work sites.

”We very clearly see the writing on the wall for the future of the drywall finishing industry,” Daley’s Drywall & Taping Vice-President Jonathan Hughes said in a press release announcing the partnership. “It tells us that we need to embrace automation sooner than later, as in right now.”

On the path to construction: The rise of women safety consultants
As safety consultants, women continue to face a unique set of challenges, including harassment, a lack of mentorship, and acknowledgment for their contributions. Women require equal access to support and networking opportunities not only to help promote gender diversity and equity in their field but also to improve the industry as a whole. By addressing these issues, women are filling the gaps and driving progress and innovation in safety consulting to create a more supportive and equitable industry.

Construction sites can be dangerous, and safety consultants are crucial in identifying potential hazards and implementing measures to prevent accidents or injuries.

For a long time, safety positions in construction have been dominated by men. But while the scale hasn’t fully tipped in their favor, we’re seeing more women step into these roles. Women bring diverse perspectives and skills to the table that can lead to innovative safety solutions, better communication, and a stronger overall safety culture.

The growing presence of women in construction safety

The construction industry is seeing a positive shift, with more women stepping into safety roles. This shift isn’t just about breaking traditional gender barriers—it marks an improvement to work site safety culture.

“I think those in management and leadership positions are recognizing that they don’t have enough ‘manpower’ or workforce to be able to do what needs to get done,” says Cory Fisk, founder of Construction Management Online. “They are being forced to open their minds to not only women employees but to younger generations who work very differently than current generations.”

Fisk’s journey into construction began accidentally. Initially, she aimed for a career in animal science but shifted to construction to pay off student loans. “I recognized that my college loans were more than I would be making in an annual salary in agriculture, and it pushed me back into the construction industry.” Fisk progressed from a laborer to a field engineer, then eventually became a college professor and started her own construction consultancy focusing on management roles.

Accidental or not, recent reports indicate that organizations recognize the value women bring to safety roles and actively recruit and support them. Between 2016 and 2021, the number of women in the U.S. construction industry increased by 32%, according to the Institute for Women’s Policy Research.

Challenges faced by women safety consultants in construction

Despite the evident uptick in hiring and retention practices for women in construction, specifically in safety roles, the industry still has a long way to go on the road to parity.

One big issue is the lack of mentors and role models. Mentorship is essential for career growth because it provides guidance, support, and networking opportunities. In that regard, Fisk considers herself lucky. “I had a mentor who was a construction manager who taught me how to read drawings and how to put change orders together and submittals,” she says.

“My greatest mentors were men, friends who took me under their wing and would take me to lunch and talk to me about stories, or just to be there when other men treated me harshly in a meeting or out on the job site, they thickened my skin and made me tougher.” However, many women struggle to find mentors, male or female, who can help them navigate their roles and advance their careers.

To that end, harassment and discrimination continue to be significant problems. Women frequently encounter harassment on construction sites, ranging from inappropriate comments to more severe forms of abuse. This can seriously affect their mental health and job performance, creating an extra barrier to their success.

“There was always sexual harassment. There were always notes left on my car after work from ‘Mister Anonymous,’” says Fisk. “There were times when I felt that I had to do things that were unsafe in order to be able to keep my job. If you resisted going down in the manhole or if you didn’t want to climb the ladders to the third story because they weren’t tied off … My hope is that that’s all changed. But I know that some of it still exists because it’s an old industry with people who have old mindsets, who don’t think to wake up until it’s too late for someone else.”

It’s astounding, then, that many construction companies don’t see the value of safety consultants. “Their bottom line is the dollar, their focus is on production. They see safety as a cost to the project instead of recognizing what it could save,” says Fisk.

“When you show your workers that you care about them, you’re investing in them, you are concentrating on making their life easier so that they can go back home to their families, there’s a different mindset and generation of energy that is going to help them want to produce for you. It’s going to make them want to be loyal to you. It’s going to increase all of the values that most companies say that they want for their employees.”

Gaining that respect from colleagues can be tough. Women often have to work twice as hard to earn and maintain respect, using various strategies to show their competence and authority. Of her past experience, Fisk says, “Besides the fact that I was a woman, I was also very young. Having them listen to me was very difficult, so I usually kept to myself and worked really, really hard.”

Women in construction safety roles are often stereotyped as less capable or knowledgeable, leading to their opinions and expertise being undervalued or dismissed. Moreover, there’s still a long-held assumption that a woman’s place is at home.

“It’s different today. Back then, it was important to be able to let it roll off your back,” Fisk says. “But now, there’s a different understanding of trying to educate men of how to work with women as co-workers instead of looking at them as mothers, wives, daughters. You know, we’re now equals and partners in our careers. Back then, it was more about survival.”

It can be disheartening for women in construction to feel that their voices are stifled or that their career paths can be blocked, even with sterling credentials. “I was reading a post from a woman bragging about having two civil engineer degrees. She was upset because they were dismissing her,” Fisk says. “Men aren’t looking at your resume. They don’t know that I have a Class A contractor’s license. They don’t know that I have a master’s in curriculum and instruction. They don’t care. Most of them got where they are without a degree, so their appreciation and value of that work is not acknowledged.”

Networking and support for women in construction safety

The good news is that the tides are slowly turning. Modern work practices and current HR policies have seeped into the world of construction, and what many have been able to get away with in the past no longer holds sway.

Improved support and networking opportunities can help women navigate the challenges of their profession while also providing opportunities for women in career advancement, mentorship, and professional growth.

The National Safety Council (NSC) is a major player in supporting women in safety roles. It offers all kinds of programs to help women grow their careers and tackle the challenges they face in the construction industry. These include mentorship programs, networking events, training, and educational resources for professional development tailored specifically for women in these roles.

Networking and support groups are equally vital for career development. They offer women a chance to share their experiences, learn from each other, and learn best practices. These groups also provide emotional and professional support, helping women navigate the hurdles they encounter in their jobs.

Below, we’ve listed some of the organizations that provide resources and programs to help women enhance their skills, stay informed about industry changes, and advance their careers:
- The National Association of Women in Construction (NAWIC): Provides educational programs, networking opportunities, and advocacy for women in the construction industry.
- Women in Safety Excellence (WISE): A community within the American Society of Safety Professionals (ASSP) that focuses on advancing women in the safety profession through mentorship and professional development.
- Women Construction Owners & Executives (WCOE): Supports women who own or lead construction companies through advocacy, education, and networking.
- Professional Women in Construction (PWC): A nonprofit organization that supports women and promotes diversity in the architecture, engineering, and construction industries.
Increasing the number of women in safety consultancy roles isn’t just about representation; hiring women often leads the industry towards a safer and more innovative future. And that’s something we should all get behind.

Alberta feeling pressure from construction labor shortages

A skilled labor shortage in Alberta is causing headaches for construction projects and jeopardizing the province’s ability to keep up with a growing population.

In early June, Calgary suffered a catastrophic break in one of its water mains, causing city officials to declare a local emergency and ask households to reduce water use by 25%. The broken pipe paralyzed the city for weeks as crews worked around the clock to complete repairs before millions of visitors descended on the city for the Calgary Stampede.

The source of the break was an ancient pipe, the sort of aging infrastructure problem that many experts warn will plague Alberta in the next few decades, especially coupled with a shortage of skilled tradespeople needed to repair it.

Alberta’s population is rapidly growing—the province added 200,000 new citizens last year alone—and with this growth comes the need to build new homes, repair roads, and upgrade critical infrastructure. Unfortunately, like the rest of Canada, Alberta is experiencing a shortage of skilled trades.

Buildforce Canada says part of the issue is the number of retiring tradespeople Alberta will need to replace. An estimated 42,500 workers (23% of the workforce) are expected to retire by 2033.

To combat this problem, the Government of Alberta has increased funding for post-secondary apprenticeship programs. Higher enrolment rates seem to indicate

the strategy has been successful, but it will take years for graduates to gain the skills and experience needed to match those hanging up their hard hats.

To fill the gap, which is estimated to reach 22,000 jobs by 2033, Alberta has also launched an initiative designed to entice tradespeople from Ontario, Quebec, and BC. The Alberta is Calling campaign promises a $5000 tax-free “moving bonus” to anyone who moves to Alberta and stays for a year while working in any of 55 included skilled trades.

In the meantime, business owners compete with large-scale industrial projects to hire the skilled tradespeople they need to get the job done.

Struggle with chronic work-induced pain? Try these natural pain management techniques
Chronic pain is one of the most common complaints among construction workers. Prescription painkillers are a quick out from chronic pain, but other options like heat and cold therapy, acupuncture, and mindfulness meditation are more natural ways to reduce chronic pain and improve quality of life.

Quick look
- As many as 75% of construction workers report suffering from ongoing musculoskeletal pain.
- Musculoskeletal injuries have consequences for workers and interfere with company productivity and safety.
- Cold and heat therapy is proven effective in reducing pain and inflammation and accelerating healing.
- Other natural (free) options, such as mindful meditation, exercise, and stress management, can help reduce chronic pain and improve well-being.
Chronic pain and construction

Jobs involving physical labor are anything but easy on the body. As many as 75% of construction workers report experiencing ongoing musculoskeletal pain, which puts them at a higher risk for substance use and overdose.

With millions of workers in construction, the industry is one of the largest in the US and Canada—it also has the highest rates of work-related injuries and suicides, along with a high prevalence of musculoskeletal pain and disorders among its workers.

A 2012 study found that about 40% of construction workers over 50 suffered from persistent back pain or problems. A similar study found that injured workers were 45% more likely to be treated for depression than non-injured workers.

Although musculoskeletal injuries undoubtedly have consequences for workers, they’re also problematic for the industry. Some of the major adverse consequences of chronic pain include:
- Mental health issues (anxiety and depression)
- Sleep deprivation
- Restricted work activity
- Tardiness and absenteeism
- Reduced quality of life
- Poor concentration and focus
- Substance misuse disorders
- Decreased productivity
- Increased suicide risk
- Increased use and costs of medical care
While opioids tend to be the treatment choice for construction workers when it comes to pain management, they’re not the only solution.

Here are some science-backed natural pain management techniques (that actually work!) to try before turning to prescription painkillers.

6 natural pain management techniques

1. Cold and heat

Heat and cold therapy are recognized for their use in acute injuries, but they’re often overlooked as a treatment option for chronic pain.

A 2021 survey from the U.S. Pain Foundation found that heat and cold therapy are actually the most-used relief options for people struggling with chronic pain. Of the almost 1,600 survey respondents, 65.7% said they currently use heat and cold therapy to manage their pain—67.8% said they use heat at least once a week, and 44.9% said they use cold therapy at least once a week.

Heat and cold therapy both offer enormous benefits for chronic pain, but their mechanisms differ:
- Cold therapy decreases the skin and muscle temperature to reduce blood flow and metabolic processes, reducing inflammation and swelling and helping to reduce pain levels. Cold therapy may also decrease nerve activity to reduce pain further.
- Heat therapy increases skin and muscle temperature to enhance blood flow and metabolic processes, accelerating healing and elasticity and reducing pain.
There are two types of heat therapy:

1. Dry heat: Sources like heating pads or bags, dry heating packs, and infrared saunas.

2. Moist heat: Sources like steamed towels, moist heating packs, hot baths/showers, or steam rooms. Moist heat is more effective and requires less time to achieve the same results.

Cold therapy includes the following practices:
- Cryotherapy
- Ice packs or frozen gel packs
- Cold plunges
- Cold showers
- Coolant sprays
- Ice massage
Applying cold and heat therapy

Heat therapy is most effective when used for extended periods. Minor muscle stiffness and tension can generally be relieved within 15 to 20 minutes of heat therapy, while moderate to severe pain benefits from sessions lasting between 30 minutes and two hours.

When it comes to managing chronic pain with heat or cold therapy, there are no hard and fast rules—experiment with both and see which works best for you. You may also find the best results come by using a combination.

2. Acupuncture (or acupressure)

Acupuncture is an alternative therapy that some research suggests could help manage chronic pain. It works on the body’s meridian lines (or pressure points). It’s believed that acupuncture stimulates the central nervous system, which releases chemicals into the muscles, spinal cord, and brain to stimulate the body’s natural healing abilities.

Acupressure works similarly—by applying gentle pressure to acupoints along the meridian lines to trigger the same effects.

Although the efficacy of acupuncture for chronic pain has been questioned, a 2012 review sought to investigate the effects of acupuncture on four chronic pain conditions: back and neck pain, osteoarthritis, chronic headache, and shoulder pain. They found that acupuncture was effective for treating chronic pain—significant differences between true and sham acupuncture suggest that acupuncture is more effective than a placebo.

Another 2018 meta-analysis on the effects of acupuncture on pain found that the modality is effective in managing chronic pain, especially for musculoskeletal pain, headache, and pain associated with osteoarthritis.

3. Capsaicin

The concept of treating like with like stems from homeopathy, which is precisely what capsaicin does—it treats pain and inflammation by topically applying heat in the form of chili peppers.

Capsaicin is the active compound in hot peppers that gives them their heat, and extensive research suggests that capsaicin has powerful analgesic properties that may benefit people with chronic pain.

Here’s how it works:

Topically applied capsaicin causes a brief initial sensitization followed by prolonged desensitization of the local pain nerves. This happens by stimulating the transient receptor potential vanilloid-1 (TRPV1), which expresses pain in nerve fibers.

Put simply, using high-concentration capsaicin topically applied can offer prolonged relief from chronic pain.

A 2020 study found that capsaicin use leads to high levels of pain relief and improvements in sleep, fatigue, depression, and quality of life. Another 2021 study found that topical capsaicin effectively reduces neuropathic pain.

That said, low-concentration topical preparations don’t offer the same benefits for pain relief. High-concentration topicals, the capsaicin 8% patch (C8P), and high-concentration liquids and injectable capsaicinoids generally accelerate the desensitization/defunctionalization state and, therefore, pain relief.

Remember: Topical capsaicin preparations may cause a mild burning or tingling sensation when applied to the skin.

4. Mindfulness and meditation

Mindfulness meditation is becoming increasingly popular as a form of natural pain relief. It works by refocusing the mind on the present and increasing awareness of external surroundings and inner sensations, allowing one to step back and reframe experiences.

While more research is needed to solidify the link between mindfulness meditation and chronic pain, initial research is promising. A 2017 systematic review and meta-analysis reviewed 38 studies and concluded that mindfulness meditation can improve symptoms of chronic pain, depression, and quality of life.

The exact mechanism of how mindfulness meditation reduces pain isn’t clear, but some research suggests that long-term meditation can change activity in specific brain regions. For example, one study found that in response to noxious thermal stimulation, “long-term Zen practitioners showed significant activation of sensory processing–related brain regions (thalamus, insula) and reduced activation in brain areas that process the evaluation of pain (medial PFC (mPFC), OFC).”

Pro tip: If you struggle to get into the meditation zone, apps like Calm, Headspace, and Insight Timer are great places to get you there—most of them are free!

6. Exercise

Exercise for chronic pain may seem counterproductive, and for most people with pain, the natural response is to stop physical activity. However, research suggests the opposite: exercise can be beneficial for people with chronic pain in the long term.

Regular physical activity can reduce the risk of developing chronic pain and can help people with existing chronic pain manage it. It improves muscle strength and flexibility and reduces fatigue, pain sensitivity, and inflammation. Other research shows that moderate exercise has an analgesic effect in conditions such as low back pain, osteoarthritis, myofascial pain, chronic fatigue syndrome, and fibromyalgia.

Exercise also produces other benefits for people with chronic pain:
1. Increases muscle strength. Regular exercise helps prevent muscular atrophy, which decreases pain by strengthening muscles and improving flexibility.
2. Reduces fatigue. Physical activity can help to reduce fatigue, a common complaint in people with chronic pain.
3. Improves sleep. Chronic pain can impede sleep quality, but research shows that regular exercise can enhance sleep quality, reduce sleep latency, and improve overall sleep quality.
4. Improves mood and reduces depression and anxiety. Chronic pain and mood imbalances go hand in hand, but regular physical activity may help improve mood and reduce symptoms of depression.
5. Reduces pain sensitivity. Some research shows that exercise may help reduce pain sensitivity compared to nonexercise training treatments. This is because exercise alters how the brain responds to pain by normalizing the pain signal process and promoting the release of analgesics.
7. Stress management

Pain and stress are adaptive processes designed to protect an organism. But if either process becomes chronic, it can lead to long-term “maladaptive” changes in physiology and, consequently, behavior, leading to suffering and compromised well-being.

Studies show that in people with chronic pain, stress is typically associated with a worsening of pain symptoms and stress-induced hyperalgesia (increase in pain sensitivity). In fact, stress and pain are highly comorbid, and they have a significant overlap in both conceptual and biological processes.

As such, managing chronic pain comes down, in part, to managing chronic stress.

Here are 7 simple tips to help manage stress:

1. Use guided meditations

2. Practice deep breathing

3. Eat a whole food, nutrient-dense diet

4. Get enough good quality sleep

5. Engage in daily physical activity

6. Connect with others

7. Manage social media and screen time

Bottom line

Chronic pain is a debilitating condition that many construction workers suffer from. Not only does it interfere with quality of life, but it also increases suicide risk dramatically. But chronic pain doesn’t have to consume your life. Heat and cold therapy, acupuncture, stress management, and regular exercise are simple (and mostly free) ways to help manage chronic pain and regain control of your life.

Tutor Perini gets $48 million Alcatraz renovation contract

Alcatraz, the infamous prison that once held Al Capone and other notorious villains, is getting a $48.6 million renovation led by general contractor Tutor Perini. The upgrade will stabilize and refurbish much of the main prison building, ensuring the safety of future tourists visiting the island prison in San Francisco Bay.

Tutor Perini is a major civil, building, and specialty construction company. Its subsidiary, Perini Management Services Inc., received the contract from the National Park Service as part of the Alcatraz Island Historic Structures Stabilization and Rehabilitation Project.

Alcatraz Prison was built as an Army prison by the U.S. Army in 1909 after it razed a previously existing fort on the island. Its desolate remoteness, reputation for being a prison that no prisoner could ever successfully escape from, and the historic criminals it once housed have inspired writers, photographers, and artists globally. It welcomes 1.4 million tourists annually.

Tutor Perini was contracted to address the deterioration of the Alcatraz Main Prison Building, including remediating structural problems. The scope of work includes replacing steel reinforcement in the walls, strengthening concrete foundation walls, repairing exterior windows, installing storm windows, and removing hazardous materials in the building’s exterior walls.

Renovations will also strengthen the structure’s ability to withstand earthquakes. This will be accomplished in part by fixing the deteriorating exterior walls and repairing concrete foundation walls, making the building weather-tight with new windows, and replacing spalling concrete.

The project is expected to begin in July 2024 and be mostly completed by the summer of 2027.

Are stricter regulations needed for interior gas line removal work?
The May 28 gas line explosion in Youngstown demonstrated the risks of having untrained workers removing natural gas lines. The calamity killed one person and injured seven, spawning one lawsuit and likely several more, which begs the question: are stricter regulations needed for the removal of interior gas lines?

Ignorance causes calamitous blast

In the Youngstown explosion, three unsupervised workers cut into a natural gas line in an occupied mixed-use building’s basement, thinking the line was abandoned. After the third cut, they realized the gas line was still charged with gas and alerted authorities and building occupants. Even still, a bank employee was killed in the explosion just six minutes after the third cut.

According to Rich Boyarko, training director for Plumbers and Pipefitters Local 396 union in Youngstown, it shouldn’t have happened. Best practices understood by union-trained plumbers would’ve prevented it from happening if they’d been doing the work.

Before line removal, double check

Although a trained plumber isn’t required to remove natural gas lines inside a building (the lines are the building owner’s responsibility, not the utility company’s), even untrained workers should understand how to do such work safely. Trained plumbers know to confirm the status of a pipe before removing it, and to re-confirm that confirmation.

According to news reports, the Youngstown workers were told before removing it that the gas line that later caused the explosion was long abandoned and inactive. But it’s unlikely they even checked the utility company valve for the line, Boyarko said, because the valve was in the street. “There’s no way I would touch a line unless I can see that valve is shut off,” he said.

Still, more than one plumber contacted for this story said that confirming the line’s supposed inactive status by simply checking the valve isn’t enough.

“As far as a plumber or anybody touching those utility lines, you would never cut into a line that you have not confirmed is dead. You’d always look to see that it’s shut off, but you need to confirm [with the utility company] on top of that,” Boyarko said.

Best practices for gas line removal

Taking the boss’s word that a line is dead is foolish, according to trained plumbers, including Boyarko and others. “I’ve seen guys hurt because someone told them the line is dead, and it wasn’t. Even if the valve is shut off and you’ve seen it, you don’t know if that valve is broken,” Boyarko said.

In addition to checking the valve to determine the status of the line to be removed, a worker should check with the utility company to confirm that the line is truly inactive.

Jim Gerard, a retired master plumber with 30+ years of experience, said other precautionary steps should be taken to prevent an explosion. Gerard’s recommended best practices include:
- Shutting off the line at the service meter (valve)
- Cutting and plugging the gas line at the first seam in the line in the building’s interior
Unfortunately, due to the often decrepit infrastructure of utilities throughout the nation, catastrophes like the Youngstown explosion might still happen even when best practices are followed. Because of the age of many gas lines, even the utility company may not have the correct understanding of their status due to their antiquated nature. A utility’s schematic of the building’s gas lines might not be accurate, or it might have been created so long ago that it’s lost and unable to be located.

Don’t mess with explosives

Natural gas is a highly explosive gas that’s combustible with even the smallest ignition source. As shown in the unfortunate case of a 27-year-old Chase Manhattan Bank employee killed in the Youngstown blast, dealing wrongly with any type of gas can quickly turn deadly, in addition to causing millions in property damage.

As kids, we are taught not to play with fire and to steer clear of explosives like firecrackers and M-80s, both of which can seriously injure people. Regardless of their training level, workers should use similar caution when working around or removing gas lines, understanding that one wrong move could be disastrous.

After all, when cutting into a natural gas line, it’s not simply a hunk of steel pipe that’s at stake. One wrong decision could cost people’s lives—and livelihoods.

The KX080-5: Kubota’s newest and largest excavator
Earlier this year, Kubota revealed its largest compact excavator, the 8-ton KX080-5. With the same specs as its predecessor, the new model offers a host of new features designed for easier operation, including a quieter and more comfortable cab, load-sensing hydraulics, and auto-idling and auto-engine stop.

The cab was updated with a new interior design and more convenience features that prioritize the operator’s comfort. They’ve reduced inside noise to 72 dBA for long-hour relief and integrated a double-adjustable seat for added comfort. Operators will also enjoy an A/C system with eight vents, including a rear one. The expanded cab space also provides more legroom, and the new foot pedal shape helps to enhance user control.

Keyless start is a standard feature on the all-new KX080-5. Operators can start the engine by entering a 4-digit passcode on the excavator keypad, and up to 10 user passwords can be set. With this new function, there’s no need to worry about theft of heavy equipment or lost keys.

A new premium display and console also enhance the user experience. A full-color, high-resolution 7” LCD screen provides all the information needed to operate the compact excavator safely. An intuitive interface ensures quick understanding and easy access to the various functions, and detailed alerts offer immediate feedback about improper machine functions and abnormalities.

Thanks to a two-pump load-sensing hydraulic system, the KX080-5 also runs attachments more smoothly when using front attachments, allowing the operator to perform simultaneous operations more effortlessly. The hydraulic settings can be adjusted from the in-cab monitor.

On the outside, the KX080-5 has also received a handful of new updates. The contoured, tight tail design, thanks to a shorter rear overhang, enhances the KX080-5’s stability and allows it to handle a wider range of loads and work in more restrictive spaces. The compact 7’2.6” width of the undercarriage also makes it a great option for working in close conditions.

The KX080-5’s Load-Sensing Hydraulics and versatile coupler options are available in mechanical and hydraulic quick-attach styles. Dual factory auxiliaries allow the user to simultaneously operate various attachments, eliminating the need to detach thumb hoses.

Feeling hot, hot hot: What you need to know about heat stress and how to avoid it
As summer approaches, temperatures rise, and unfortunately, the risk of heat stress rises, too. Occupational heat stress can affect anyone at work, but construction workers represent a particularly high-risk group. The most common symptoms of heat stress include headache, dizziness, nausea, rapid pulse, and clammy skin. If left untreated, heat stress can lead to more serious heat-related issues, some of which may be fatal.

From 1992 to 2016, construction workers were just 6% of the population but accounted for 36% of all occupational heat-related deaths. To survive the summer, it’s important to understand heat stress prevention, be aware of heat stress symptoms, and learn how to treat heat stress effectively when it does occur.

Quick look
- Extreme heat can cause heat stress. If left untreated, heat stress can lead to more serious heat-related issues, some of which may be fatal.
- High humidity levels can lead to higher wet-bulb temperatures and impact your ability to cool off effectively.
- Heat stress symptoms include headache, dizziness, nausea, rapid pulse, and cool, clammy skin.
- You can prevent heat stress by wearing loose-fitting, light-colored clothing, drinking plenty of water, and protecting your skin from the sun.
Heat-related illness

Heat stress occurs when your body begins to heat up faster than it can cool down. A combination of several different factors causes occupational heat stress:
1. The heat your body naturally gives off
2. Aspects of your environment like humidity levels, temperature, and radiant heat sources
3. Clothing you’re required to wear to do your job, like high-vis vests or hard hats
Heat stress is more than just feeling hot and sweaty; it’s a canary in a coal mine warning you that your body can’t cool itself effectively. If left untreated, heat stress can progress to more serious conditions like heat rash, heat exhaustion, and even heat stroke, which can be fatal.

Heat doesn’t just mean dry heat, either. Humidity can compound the effects of high temperatures, creating a more significant impact by impacting the body’s ability to cool off naturally.

Wet-bulb temperature: the effects of humidity

Determining the temperature outside is a little more complicated than just reading the thermometer. If you’ve ever seen a summer weather report that includes the temperature and also the “feels like” temperature, you’ve seen the wet bulb effect in action.

While regular temperatures measure heat, wet bulb temperature also takes humidity into account. Wet-bulb temperature is measured by placing a wet cloth over the bulb of a thermometer. When moisture evaporates from the cloth, it mimics how we cool down by sweating.

When humidity is high, however, it means there’s already plenty of moisture in the air. It takes longer for sweat to evaporate, making it harder to cool down. We lose about 85% of heat through sweating, and it’s easy to become overheated when we can’t cool down due to high humidity.

Watch out for symptoms of heat stress

Identifying when you or someone else is experiencing heat stress is crucial to treating it effectively. Watch out for these heat stress symptoms:
- Cramps
- Weakness, dizziness
- Heat rash
- Headache
- Nausea
- Thirst
- Shallow, rapid breathing
- Cool, clammy skin
- Fainting
- Agitation or confusion
If you experience any of these symptoms, notify your supervisor, get out of the sun, find somewhere cool to rest if possible, and drink water. Seek medical attention immediately if symptoms persist.

How to protect yourself (and others) from heat stress

There are several proven ways to reduce the risk of heat stress and keep cool during those scorching summer days (well, cooler, anyway).

Avoiding heat stress in the first place is much easier than trying to treat it when it happens, so consider the following strategies for heat stress prevention.

Cool clothes

It might be tempting to wear less clothing on a hot day, but keeping the sun off your skin with appropriate clothing is vital to keeping cool and preventing heat stress.
- Choose a light-colored, long-sleeved shirt instead of a tank top. Lighter colors help reflect the sun’s rays, and long sleeves will protect your skin from sunburn.
- Clothing material also matters, so look for natural fabrics like cotton or bamboo that help air circulate freely.
- Wear loose-fitting clothing to let your skin breathe; tight clothing tends to trap heat.
- Shirts made of lightweight Merino wool can help you cool down by wicking moisture away from your skin.
Wear a hat

Just like long-sleeved shirts keep the sun off your skin, wearing a hat can reduce your risk of heat stress by keeping the sun off your face and neck.
- Choose a wide-brimmed hat over a baseball cap. It offers more coverage and protects the back of your neck from getting burned.
- If you are working on a job site that requires you to wear a hard hat, tuck a t-shirt or kerchief into the back to provide shade for your neck.
Stay hydrated

Sweating is an efficient way to stay cool, but it also uses a lot of water. Some studies estimate that working outside in a hot environment can mean losing up to 1.5 liters every hour. To prevent heat stress, you must be diligent about replacing that water loss throughout the day.
- WorkSafeBC recommends drinking half a liter of water before starting work on a hot day and another eight ounces every 20 minutes or so (don’t wait until you’re thirsty!).
- Limit caffeinated drinks like cola, energy drinks, or coffee because they can increase dehydration.
- Adding electrolytes to your water can help you replace critical vitamins and minerals lost through sweat.
Stay proactive to beat the heat

It’s often said that the best defense is a good offense, and that’s certainly true when it comes to heat stress prevention. This summer, stay informed about weather forecasts and note any days forecasted to be particularly hot or humid. Bring enough water to get you through the day, and use the tips above to dress in clothing that will keep you cool.

Finally, care for yourself and your coworkers by recognizing and looking out for heat stress symptoms.
