How many degrees should you add to the WBGT index when wearing MOPP gear?

When wearing MOPP (Mission-Oriented Protective Posture) gear, it is recommended to add 10 degrees to the Wet Bulb Globe Temperature (WBGT) index. The rationale behind this adjustment is that MOPP gear significantly increases the thermal burden on a service member's body. The material and design of MOPP gear can trap heat and moisture, leading to an elevated risk of heat stress and heat-related illnesses in environments where temperature and humidity are already high.

The WBGT index is a critical measurement used to assess heat stress and ensure personnel safety in hot weather conditions. By increasing the WBGT index by 10 degrees, you effectively account for the additional strain that the protective gear places on the body, allowing for more accurate monitoring of heat stress levels. This adjustment is essential for making informed decisions about work/rest cycles, hydration needs, and overall readiness, helping to maintain health and performance in challenging conditions.
