KANSAS CITY, Mo., January 18, 2022–(BUSINESS WIRE)–Record-breaking temps of 2021, including in July, the earth’s hottest month ever with 200 million Americans under heat advisories, increased worker deaths – from produce pickers to construction crews to garbage collectors. Extreme temperatures are expected to result in annual losses of two billion labor hours and $162B in wages, with every 10 degree (F) temperature increase causing a 393 percent uptick in hospitalizations for heat exposure.

In 2022, the problem is getting attention: President Biden has announced emergency Federal Heat Rules and tasked the Occupational Safety and Health Administration (OSHA) to set new standards. Tech entrepreneurs are innovating ways to track and prevent the dangers of heat on the body.

“There is new tech that can save workers’ lives,” said Heidi Lehmann, a tech entrepreneur whose latest venture is Kenzen, maker of a wearable device that monitors workers’ physiology to predict and prevent heat injuries and deaths. “Progressive employers are already incorporating tech that tracks worker wellness.”

Kenzen has equipped first responders, miners, and workers in construction, energy, steel, and manufacturing with sensors that continuously monitor their physiology to assess core body temperature, sweat rate, and exertion. She welcomes legislation that will mandate the care needed for overheated bodies – breaks, water, and cooling techniques – yet warns that standards should not be one-size-fits-all. Biological sex, age, fitness, acclimatization, and other individual factors dictate what each worker needs to stay safe and productive.

“Heat monitoring is key to achieving ‘Total Worker Health.’ Every person has a different threshold for being able to withstand hot temperatures and hot work. Across-the-board mandates will not curb the alarming statistics. Advanced technology for a personalized approach needs to be part of the solution,” said Lehmann.

Kenzen sensors gather tens of thousands of data points per worker per shift. Through research and validation with top universities and use of its system by more than 50 companies, Kenzen has amassed the largest known dataset of continuous core body temperature in the world.

The Kenzen device warns workers, via haptic vibration, when their physiology indicates danger of heat stress. Managers get an alert via an app when a worker needs an intervention to stay safe. A second alert indicates when the worker’s body is ready to resume work. Corporate safety leaders use an analytics dashboard to make enterprise-wide decisions to minimize heat risks, reduce injuries, and improve productivity. They may adjust work schedules or assign certain tasks to individuals. Throughout the process, personal data is protected; only workers can view their health information while others only see what is necessary to keep workers safe.

“Worker heat health is at the forefront of industry in 2022,” said Lehmann, whose backers include Working Capital Fund, which invests in companies that meet the growing demand for more transparent and ethical supply chains that protect workers.

NEW YORK CITY (March 23, 2021) – Kenzen has launched a data and analytics dashboard, the latest component of its smart PPE connected worker solution. The dashboard captures workers’ core body temperature (the greatest predictor of heat stress and illness), productivity, and microclimates caused by clothing under hot and humid working conditions. 

Environmental Health and Safety (EHS) managers and company leaders can now have a data-driven overview of work sites, both real time and retrospectively, to evaluate heat risk information by location and job role. The analysis consists of tens of thousands of data points collected per worker per day from the Kenzen wearable which tracks physiological factors including core temperature and heart rate. The Kenzen system uniquely enables companies to identify and address challenges and opportunities related to work in hot and humid conditions. The information allows them to manage risk and improve processes to keep workers safer and more productive. 

Last year, Kenzen unveiled the monitoring device and its complimentary mobile app that alerts workers when they are at risk of heat stress and illness and when to stop work, rest, and return to work safely. The hardware and app work together to feed data to the real-time dashboard for supervisors to monitor their teams proactively and intervene when necessary. 

Kenzen’s new analytics dashboard allows senior managers, who on average are responsible for 10 teams of 10 people each day, to dig deeper into the data and have a holistic view across worksites and teams. The dashboard provides insight into how various environments affect workers and uses the information to guide management in the implementation of changes to keep workers safer while optimizing productivity. Actionable feedback enables tailoring of work/rest schedules and identification of PPE clothing with the least impact on worker performance. 

The complete Kenzen solution integrates the company’s commitment to personal data privacy; only workers can view the details of their personal health information and safety managers and other EHS leaders only see what’s necessary to keep the worker safe. 

“The latest tool in the Kenzen connected worker solution comes just in time for a summer that’s expected to be one of the most extreme on record,” said Heidi Lehmann, Kenzen co-founder and chief commercial officer. Lehmann adds that, for every 10-degree Fahrenheit increase in temperature, there is a 393 percent increase in hospitalizations for heat exposure. “Now companies have the power to predict and prevent heat-related injuries and deaths and manage productivity at the same time.”
