Kenzen develops body heat sensor for predictive worker safety

Kenzen PPE

Smart PPE developer Kenzen has launched a wearable real-time worker heat monitoring system. 

The cloud-based Software as a Service (SaaS) system includes a wearable device worn by workers on their arm, which alerts both the worker and their supervisor when core body temperature is too high. 

Real-time alerts allow for immediate intervention and worker safety from heat injuries.

The wearable tech, via its advanced sensor, monitors multiple physiological and environmental metrics, including heart rate, activity, skin and ambient temperatures. The sensor data allows for the real-time prediction of core body temperature, providing alerts to workers and supervisors when temperatures approach unsafe levels. 

“The Kenzen system is all about prediction and prevention. Heat related injuries are 100 per cent preventable, but potentially deadly and difficult to detect until it’s too late,” said Heidi Lehmann, Kenzen’s chief commercialization officer. 

Kenzen’s multi-level alerts are sent to workers via device vibration, iOS or Android app notification and to supervisors via web dashboard alert signalling the worker should take a break and to allow their temperature to return to safe levels.  

Alerts are accompanied by actionable recommendations such as advising the worker to take a break, find shade, drink water or remove any excess clothing and equipment to decrease body heat. 

When the worker’s core body temperature has returned to a safe level, a second “back to work” alert notifies the employee.

Data captured by the system can be used to help companies identify heat risk and manage outcomes by adapting worksites accordingly to improve worker safety while maximizing productivity. 

Modifications may include changes to work-rest schedules, where and when to add water and shade stations, the addition of air-conditioned rest areas and even recommendations for pre-staging ice-bath locations in case of extreme weather and working conditions. 

The data can also inform decisions around workplace expenditures such as certain equipment and clothing. 

The Kenzen system has been tested on worksites of large industrial conglomerates across the globe in domains such as construction, field services, power, oil and gas as well as renewable energy.

In the future, open APIs will allow integration into large connected-worker platforms. Kenzen also expects to receive Intrinsic Safety (IS) certification for use of its system, a perquisite for use in many oil and gas, mining and other enclosed environments later this year.  

Once approved, the system would be among the first smart PPE products to receive Zone 0 IS certification, which authorizes safe operation of electrical equipment in hazardous areas where any thermal or electrical malfunction is catastrophic. 

Kenzen is sold as a subscription on a per-worker, per-month basis.
