Heat Index (HI) monitoring has been added to all Room Alert models that monitor humidity, including AVTECH's new Signal Towers. This functionality will assist in monitoring Heat Index parameters as required by labor agreements and regulations where workers are packaging products, loading trucks, and completing other labor intensive work where body temperature can impact a workers health and safety. Maintaining an adequate Heat Index allows an organization to insure a healthy work environment for employees, protecting them from heat fatigue and helping to increase overall efficiency.
AVTECH was contacted in 2007 by Amazon.com and UPS who were both looking to better protect their employees by automating the monitoring of work environments. Heat Index represents how hot it 'feels' by mathematically combining the current temperature and relative humidity. In extreme heat conditions, the human body regulates temperature through perspiration. Heat is carried away from the body as the water in sweat evaporates. However, when the humidity is higher, the water does not evaporate as fast and causes the body temperature to feel warmer than it actually is. As a result, this increases internal body heat to cause fatigue and reduce strength. In extreme cases, working at higher Heat Index levels can cause heat stroke, cardiac arrest and even death.
