21
Q

recovery time

A

minimum of twice the stay time as determined by the PHEL chart or 4 hours, whichever is shorter

22
Q

fuel combustion gases (stack gas)

A

combustion gases which may accumulate in a space due to inadequate ventilation or machinery malfunction

causes vasodilation on peripheral blood vessels which further impairs cardiovascular system

23
Q

signs and symptoms of fuel combustion gases

A

watery eyes
dyspnea
tingling or numbness of the tip pf the tongue, nose, fingers/toes
mild sensation of alcohol intoxication

if 2+ detected reduce exposure limits
uses tale B2-A-5 of divide PHEL stay time by 3

24
Q

who must provide heat stress training during indoc and annually

A

MDR

25
Q

heat stress training at a minimum must include

27
Q

what are the requirements for REPORTING heat stress injuries

A
  • accident and injury report
  • report to Naval Safety Center using Web Enabled Safety System (WESS)
