Innovative heat monitoring technology helps safeguard workforce.

Perennially recognized as one of America’s safest builders, McCarthy Building Companies, Inc. is partnering with Kenzen to pilot wearable heat monitoring technology on multiple construction projects. Kenzen’s smart PPE devices monitor the heat status of workers in hot and humid conditions, helping predict and prevent heat stress and illness. Together, the organizations will gain valuable insight into how the technology can minimize the risk of heat illness and protect the broader construction workforce.

“Safety is the most important thing we do every day, and on many projects that includes heat awareness and heat illness prevention,” said McCarthy Vice President National Safety Pat Devero. “The Kenzen system is already helping us identify new ways to prevent heat illness, assist in validating our current practices and heat illness expectations, and is a great example of how embracing technology can improve our industry’s approach to health and safety.”

The Kenzen devices worn by workers contain sensors that monitor, in real-time, an individual’s physiological markers that trigger heat injury risks. This includes a sweat rate monitoring feature that uses a worker’s information and physiological data to calculate and predict their sweat rate in liters per hour. Using a proprietary algorithm, the Kenzen device can alert workers of dangerous heat stress via a smart phone app. The data helps eliminate guesswork about how to keep workers safely hydrated and makes it possible for individual workers to know the specific amount of water they need to drink to stay safe.

On-site managers have access to alerts and corporate safety leaders use an analytics dashboard to monitor and evaluate risks to individuals and teams, helping them optimize worker safety. McCarthy will use the technology to identify broad trends that affect all projects and implement preventative measures to increase safety and productivity.

“The Kenzen pilot was a valuable program for our jobsite,” said Andrew Rhines, McCarthy Project Safety Coordinator in Texas. “It benefitted the craft professionals on our site and the data gathered by Kenzen helped verify many different aspects of our national heat illness prevention plans including water consumption and scheduled breaks.”

McCarthy and Kenzen are equally committed to protecting user data; the system does not reveal personal information or reasons why someone is in a particular heat risk category; it is only used to monitor and manage people according to their individual heat susceptibility.

McCarthy makes education about heat illness and injury prevention a priority during the spring and early summer as temperatures increase. The company shares educational information internally, hosts on-site educational and training sessions, and makes resources available for its workforce in-person and online. On projects in high heat areas, McCarthy provides hydration aids, shade stations, cooling fans and brimmed head protection to reduce heat. It’s also common for the projects to alter schedules, allowing the day’s work to be completed before the hottest portion of the day.

From 1992 through 2017, there were 70,000 serious injuries and 815 deaths caused by exposure to excessive heat, according to the Bureau of Labor Statistics. Of the 492 occupational fatalities attributed to exposure to environmental heat from 2003 to 2016, 179, or 36 percent, were in the construction industry.

“McCarthy is a leader in exploring all opportunities to keep employees safe,” said Heidi Lehmann, Kenzen co-founder and President. “With the Kenzen system, they can tailor their approach to individuals, teams, and projects because they have access to new, highly detailed information. This information helps manage risk, realize increased productivity, and meet every worker’s unique requirements for working safely.”

McCarthy has selected several pilot opportunities for the Kenzen system on jobsites in Arizona, Georgia and Texas. Employees using the system understand the protective value it offers and appreciate receiving notifications about their core body temperature, sweat rate, and hydration status – when they should stop and rest, and when it’s safe to return to work.

“The Kenzen system has been a successful initiative for our team and how we approach heat illness risk onsite,” said Sean Blakemore, McCarthy Project Safety Manager in Texas. “The entire Kenzen team is resourceful and is helping us maximize management of the program. The data we’re gathering is a significant benefit for us to not only verify and confirm our current approach, but it also helps everyone understand what drives the additional mitigation measures we take in order to send everyone home safely at the end of each day.”

Startland News’ Startup Road Trip series explores innovative and uncommon ideas finding success in rural America and Midwestern startup hubs outside the Kansas City metro. This series is possible thanks to the Ewing Marion Kauffman Foundation, which leads a collaborative, nationwide effort to identify and remove large and small barriers to new business creation.

Plug and Play Topeka is back, Lindsay Lebahn said, announcing the accelerator program’s second cohort of startups — including a surging Kansas City company — and revealing ways the effort has redefined the definition of entrepreneurship in the Sunflower State’s epicenter.

“Realistic expectations of Topeka have changed,” explained Lebahn, program manager and a key player in bringing the San Francisco-based accelerator’s presence to Topeka two years ago.

“Topeka is really starting to believe in Topeka. … I think a lot of that [has to do with the] revitalization of downtown. We’ve had a lot of things happen throughout the years, but they would happen in pockets,” she continued, highlighting the efforts of GO Topeka to establish an innovation hub and center near and along Kansas Avenue — and a massive opportunity for connectivity in Shawnee County that comes with it.

“Things were happening, but not necessarily in a centralized location. Unless you lived in that area or visited that area, you didn’t really notice it and didn’t really feel it … but this revitalization of downtown has really helped the momentum of Topeka and I think Topekans are now starting to realize that there’s stuff to do here, there’s opportunities.”

Having successfully launched its first cohort virtually earlier this year amid the COVID-19 pandemic, Plug and Play welcomed 10 new startups into its animal health program last month. Among them, Kansas City-based Kenzen — a biometric platform and maker of a workplace safety, smart patch that monitors heat, fatigue and over exertion on the job.

Additional participants, chosen by founding partners of the Plug and Play Topeka program Cargill, Evergy, and Hills Pet Nutrition, include: Aegis Packaging, Singapore; Birdstop, San Francisco, California; ISO Thrive, Manassas, VA; Lumin, Charlottesville, Virginia; Maven, Portugal; Nanox, Newton, Massachusetts; Pepperai, New York, New York; Sniffypet; Calgary, Alberta; and Tarot Analytics, Paris, France.

“It’s more than just animal health,” Lebahn said of the cohort and the problems they’re working to solve.

“We’ve seen a lot more [companies tackling] sustainability [and] workforce issues with COVID changing everything. Our partners are really looking to make sure that they are doing everything they can for their company and to make sure that they’re the top of the line, they’ve got the newest, latest, greatest technology.”

Less than a month into the program, current cohort companies have already received interest from venture firms who’ve participated in the program — just one result of Plug and Play’s intentional, cross-vertical programming and events, which see frequent collaboration with its North Dakota-based agtech accelerator and its Silicon Valley-based food-focused program.

Nine nondisclosure agreements have been signed between startups and corporations involved in the first program, Lebahn added, indicating there’s power in the program and its setup.

As Nation Gets Hotter, Efforts to Prevent Worker Heat Deaths Accelerate, But Fixes Aren’t as Simple as They Seem

As Nation Gets Hotter, Efforts to Prevent Worker Heat Deaths Accelerate, But Fixes Aren’t as Simple as They Seem

Technology could help make up for the imprecision of generalized rules. Last year, Garney Construction, a water and wastewater construction company based in Kansas City, Missouri, with offices around the country, partnered with Kenzen, a New York City-based tech startup, to pilot Kenzen’s wearable biometric sensor. The sensor, strapped around the upper arm, monitors indicators such as heart rate and core body temperature and alerts workers if they are showing signs of heat-related illness. The devices also send a warning to supervisors, though details are kept hidden to protect workers’ medical privacy.

Ryan Smith, eastern regional safety manager at Garney, said the sensors were tested last August and September on about 70 workers at 12 sites.

The sensors revealed some interesting data, Smith said. For example, workers at a Colorado site were overheating earlier in the day than expected, most likely because they were wearing more clothing in the cool mornings. The revelation prompted the employer to give workers a break specifically to remove the extra clothing. Heidi Lehmann, Kenzen’s co-founder and chief commercial officer, said the software platform that supports the sensors starts at about $40 per worker per month, with each sensor collecting tens of thousands of data points during an employee’s shift.

By the end of this year, up to 5,000 of the sensors are expected to be in use worldwide, Lehmann said. In the meantime, Kenzen is compiling a trove of data related to heat-illness risk factors, which could provide new insights for prevention.

Protecting Workers in Extreme Heat

Heidi E. Lehmann | September 1, 2021

As one might imagine, extreme heat can lead to an increase in workplace injuries. According to a recent study by researchers at the University of California, Los Angeles, hot days do not just mean more cases of heat exertion and stroke. Heat stress on the body also leads to a greater incidence of falls and vehicle or machinery mishandling due to loss of concentration. These incidents lead to an additional 20,000 workplace injuries each year in California alone.

On days when the temperature was 85 to 90 degrees Fahrenheit, the researchers found the overall risk of workplace injuries was 5% to 7% higher on days when temperatures were in the 60s. When temperatures reached 100 degrees, the overall risk of injuries was 10% to 15% higher.

In general, heat-related injuries occur in just about every major group of workers across industries that the U.S. Bureau of Labor Statistics tracks. In 2018, 3,120 workers missed at least one day of work due to environmental heat, and more than 1,100 of those workers were in the construction and transportation industries. According to OSHA’s occupational injury cost estimator, using an average 6% profit margin for construction, the direct and indirect costs of a single heat-related incident require about $1.3 million in sales to offset.

According to the National Oceanic and Atmospheric Administration (NOAA), 2020 was the second-warmest year on record—just 0.04 degrees Fahrenheit cooler than 2016. In addition, the world’s seven-warmest years have all occurred since 2014, and 10 of the warmest years have occurred since 2005. As extreme heat becomes more common, organizations around the world must ensure they are taking proactive measures to protect workers.

 

How Heat Stress Happens

As a person’s core body temperature rises, sweating is the primary natural mode of cooling down. Blood flow increases to the skin, water and electrolytes are expelled by the sweat glands, and evaporation of sweat cools the body. This process is efficient as long as evaporation can occur, activity level does not increase, and hydration is adequate. However, workers on job sites are subject to their environment and productivity requirements, which may disrupt the body’s cooling process.

The heart rate needs to increase during sweating to pump blood fast enough to get it to the skin to cool off the body. Muscles also require blood to get oxygen and other nutrients for proper function during work. This means the cardiovascular system is strained when working in the heat, sending blood to everywhere it is needed. If a worker is sweating and maintaining a steady workload, eventually they are going to feel the fluid loss from sweating. The sweat loss will result in lower blood volume and pressure.

Working in hot weather impacts the nervous system as well, decreasing a worker’s ability to complete their tasks and affecting their cognitive ability. The nervous system needs to work harder to accomplish the same muscle movement it did when the environment was cooler. This makes work-related tasks harder and cognitive decision-making more difficult.

Adaptation to heat takes time and varies by individual, but the process typically takes two to three weeks when managed properly. Appropriate heat acclimatization is accomplished by increasing one’s core body temperature one degree Celsius for an hour each day. If the job requires workers to wear personal protective equipment (PPE), as most do, they need to slowly add PPE as well, for example, adding 20% each day and working toward full worksite coverage.

Keep in mind that heat-related injuries can also happen in cooler weather, particularly if a worker is over-exerting or dressed too warmly, causing overheating in their microclimate (the temperature between the skin and clothing).

 

Monitoring Heat Health

Measuring an employee’s heat health is imperative for detecting the onset of heat stress and taking steps to prevent incidents, injuries and even death. The standard method of measuring an employee’s core body temperature, the primary indicator of an issue, has been through gastrointestinal pills. Workers swallow one of these pills and a wearable device tracks their temperature over a set period of time as the pill moves through the body. Thermometers can also be used to get a temperature reading, but they do not scale well in workforces and only capture temperature at one point in time.

As workers go through their day, their physiology changes based on the conditions and their body’s response, so it is most helpful to track individuals’ health through continuous monitoring, such as via wearable devices. This allows the employee, supervisor and company to get real-time data that prompts an intervention to restore optimal body temperature and allow return to work, increasing productivity and safety.

Some organizations have started using smart PPE technology to enhance safety and minimize risk. Workers don devices with sensors that monitor heart rate, temperature and sweat rate. These are tracked against the individual’s heat susceptibility, as determined by factors including gender, age, underlying health conditions, current medications, and ability to acclimate. Some devices can send alerts to workers to warn them of stresses to their body, and send these alerts to their supervisors and company. Supervisors can then call a time out for individual workers to restore their bodies to safe working levels, while companies can track health data in various conditions at worksites and across multiple teams for a holistic view of their workforce’s health. Because core body temperature affects the work, this technology can also track productivity at the individual, team and corporate levels.

 

Preventing Heat Risk for Workers

There are a number of ways to protect workers from the impact of heat. Encourage workers to use a buddy system while on the job. Buddies are responsible for checking on specific coworkers’ well-being and they should talk to each other several times during the work day. If one person notices something strange or out of character with the other, they should alert supervisors and immediately get the person to an emergency cooling station on-site.

Educate workers on the signs and symptoms of heat stress. Encourage them to pay attention to their own symptoms and what their body may be telling them. Let employees know it is dangerous to “push through” the situation by being “tough” under extreme circumstances. It is not productive for the job—heat stress actually slows the work pace and increases errors. Working safely is the goal, not speed or testing the limits of the human body.

Acknowledge when a worker is vocal about symptoms and take all comments about changes in the body seriously. When the onset of heat stress is detected, stop the individual from working, get them to shade or air conditioning, and encourage them to drink fluids, especially water. Check on the person every five minutes to make sure they are recovering and feeling better. After 10 to 15 minutes, they may return to work if their symptoms have subsided. If not, continue treatment to eliminate the symptoms or seek professional medical attention for the worker if symptoms do not subside.

If the worker exhibits symptoms of heat stroke (when their body temperature reaches 104 degrees Fahrenheit and they are confused or vomiting), immediately call for emergency medical services. While waiting for emergency assistance to arrive, help the worker cool down as quickly as possible. If available, try using ice baths or rotating cold compresses around the person’s body. Most importantly, do not leave their side until help arrives.

Heat-related injuries are almost entirely preventable. The latest techniques and tools, such as wearable devices, can help organizations understand the potential severity of the problem and respond appropriately, better protecting employees in extreme working conditions.
