If There’s a Red Flag: No Strenuous Exercise Allowed

Now here is something really interesting, if you want to monitor heat stress at your work site.

In order to monitor heat and humidity, the U.S. Navy started using a Wet Bulb Dry Globe Temperature (WBGT) meter. The Naval Health Research Center (NHRC) and Naval Sea Systems Command Smart Ship initiative simplified the process of monitoring heat stress conditions on board Navy ships (see related story). The meter continuously records real time data on ambient dry/wet bulb temperatures, radiant heat globe temperature, and relative humidity, which is then transmitted to a PC for graphical representation and guidance on exposure. Hazard warning flags are then posted to advise personnel. If you’re interested in learning more, click here. You might find something you can create at your own site.
