What weather conditions lead to a Black Flag Day?
WBGT above 90.
When WBGTI(Wet Bulb Globe Thermometer Index?) is above 90 degrees black flag conditions are declared and specific restrictions are put in place by the command to ensure the health and safety of all personnel. I am certain there is a command instruction, probably issued by the commandant, that details the specific restrictions that are put in place under various flag conditions, i.e. red or black flag. Personnel who have not become acclimatized to the heat stress conditions in a specific area are prone to heat illness/injury. Most commands, as I recall, require a 21 day minimum acclimatization period for new joins, USNA probably does something similar. Once red or black flag conditions are declared, there is usually more frequent monitoring of WBGTI required along with specific announcement and reporting requirements. Last year when we visited in August there were black flag conditions and things such as noon meal formation and drill outdoors were cancelled or relocated. We saw several companies doing drill in Dalgren.
Thank you for the information.
The Plebes make some really nice arts and crafts stuff on these days though. I've a great lanyard and mug!
Sell 'em @ PPW.
Under red and black flag conditions, water intake is regulated and physical activities are restricted.
Under red flag, there is no outdoor PEP, the PRT is not given, there are no outdoor intramurals, and the O-course and E-course are not run. There are restrictions on ITE and DPT. Indoor intramurals still happen.
Under black flag conditions, all of the above apply, PLUS the plebes are directed to drink 1-1/2 quarts H2O per hour, there are no outdoor classes (not just physical ones), and whiteworks "echo" (which is both the UOD and working U the first 2 weeks of PS) is modified such that plebes may carry the blouse instead of having to wear it. There is no ITE/DPT.
Enclosure (1) to COMDTMIDNINST 5090.1A has a great chart of precautions taken during different heat stress conditions.
