Fort Belvoir’s Directorate of Plans, Training, Mobilization and Security announced this week that, due to extreme heat, Fort Belvoir gates will operate with reduced operational lanes, when it’s extremely hot. This allows Department of the Army Security Guards to increase the frequency and duration of cooldown breaks.

Fort Belvoir Community Hospital reports Wet Bulb Globe Temperatures and the corresponding ag condition, based on the WBGT. Black Flag Conditions, WBGT of 90 degrees Fahrenheit and above requires physical training and strenuous exercise to be suspended for all personnel. Additionally, wearing body armor adds approximately 10 points to the measured WBGT index, meaning a WBGT of 80 degrees would be equivalent to 90 degrees (Black Flag conditions) for Security Guards wearing body armor.
