Garney trials new Kenzen smart device to protect workers from heat stress


Garney, a firm focused singularly on water and wastewater construction, is interested in keeping its employee-owners as safe as possible on the job. Recently, the company added a new element to its already robust safety programs by testing new wearable technology smart devices.

The devices, worn on the arms of 28 Garney workers at 10 worksites throughout the U.S., are manufactured by Kenzen. They monitor key physiological indicators of each worker, including core body temperature, heart rate, and exertion level. Detecting changes in these factors can lead to proactive prediction and prevention of heat injuries and illnesses, including fatalities.

“We’re committed to continually evaluating new methods of protecting our employee-owners and incorporating the best solutions available,” said Ryan Smith, regional safety manager at Garney who coordinated the proof-of-concept project with the company’s environmental health and safety (EHS) leaders and regional project supervisors. “We’re looking to add more prevention approaches to our systems, which now include education and training, hydration, monitoring atmospheric and ambient heat, and cooling stations.”

Data from the wearable sensors provide alerts to workers by sending vibrations to the device and notifications to their smartphones, and to supervisors via their phones and a web dashboard that provides real-time heat health status of all team members. Alerts escalate from an initial “stop work” message to rest and hydrate, to subsequent alerts for additional measures to avoid emergency situations. Follow-up alerts indicate when a person’s core body temperature has returned to a safe level for resuming work.

Cumulative data can be analyzed by EHS leaders at the company to detect patterns and customize heat stress prevention and treatment strategies at various locations – from the dry heat of Arizona to the extreme heat of the Texas sun, to the hot humidity of Florida, and heat conditions at Colorado altitudes. Garney used the location-specific information to adjust break times and educate employee-owners on steps they can take to protect themselves, such as how to acclimatize to warm working conditions when coming onto a worksite, and best clothing choices.

Although Kenzen collects large amounts of physiological data from each worker, varying levels of information are provided to different viewers to protect workers’ rights, especially with regard to the privacy of their personal health information.

“Garney is on the leading edge of bringing technology into the safety equation,” said Heidi Lehmann, co-founder of Kenzen. “Because Garney is owned by its employees, all were involved in the decision and all are interested in advancing their business through increased safety and productivity.”

September 5, 2018 (Minneapolis) – Sofia Fund, a leading angel investment group focused on high-growth, women-led early stage companies, today announced its most recent investment in Kenzen, a San Francisco-based health analytics platform focused on predicting and preventing avoidable health conditions. Kenzen is the maker of Kenzen Patch™, a wearable vital sign and sweat-analysis system that continuously monitors parameters needed to detect heat-related injuries in workers and at-risk individuals.

The Sofia Fund investment brings Kenzen’s total amount raised to $7 million, which will be used for product enhancements and acceleration of market adoption of the Kenzen Predictive Workforce Solution. The Kenzen platform uses real-time biosensor data and predictive models to detect heat-related health events before they occur. Patches on workers monitor sweat rate, heart rate, body temperature and active time in high-risk and extreme environments. The solution is currently gaining substantial traction globally with paid pilot projects in the U.S., the Middle East and Japan.

“Kenzen is exactly the type of company Sofia Fund looks for – a company of women founders and leaders in science and tech who create products that truly have an impact in the marketplace,” said Joy Lindsay, Sofia Fund partner. “Kenzen technology is at the intersection of Internet of Things (IOT) wearables, sensors and data analytics, all areas of great promise for product innovation. With the diversity and solid structure of its leadership team, we believe Kenzen is set for up for success in this exciting space.”

Kenzen is the second company Sofia Fund has added to its portfolio this year. Sofia Fund also invested in Joylux, a femtech company that creates innovative health solutions targeting the enormous but underserved female intimate care market. Sofia Fund has also made follow-on investments in two of its existing portfolio companies.

“An infusion from an investor like Sofia Fund is particularly meaningful to our team,” said Jim McDonnell, who became CEO of Kenzen after the passing of co-founder Dr. Sonia Sousa. “Sonia always recognized the power of diverse teams to propel businesses to success. Like the partners at Sofia Fund, she was an inspiration to many women founders and entrepreneurs”.
