Description of the flag system

Quoting Nicole E. Squibbs, "The Yuma Sun", 3 September 2007:

"The Marine Corps Air Station Yuma has its own system to warn Marines of the dangerous heat conditions in Yuma to help prevent heat-related injuries such as heat exhaustion or heat stroke, according to MCAS Yuma's Lance Cpl. Daniel Angel. The four different flags are green, meaning heavy exercise can be conducted with caution; yellow, meaning troops who have spent less than two or three weeks in our climate cannot complete strenuous activities; red, meaning unacclimatized troops cannot have physical training and others are limited to six hours; and black, meaning no strenuous physical activity, according to the U.S. Marine Web site,
He said flags are located on the front and north gates to the base, at the weather office and at the gym. Fossum said the flags provide guidelines for how much work can be done in the heat and how much water Marines need to drink to stay hydrated. Fossum said with the hot and humid August weather, the black flag has often been flying by 1 p.m.
