Heat Stress Survey Flashcards
***Define Heat Stress
combination of thermal radiation, air temp and flow, humidity, and work load.
what are the environmental factors causing heat stress
Thermal Radiation
Ventilation
Humidity
Air/sea water temp
***Define acclimatization
the act of becoming accustom to temp or new environment
Acclimatization happens how
gradually within 3+ weeks
How does past exposure heat injuries affect an individual
decreases the ability to handle heat stress conditions
what are the med history factors that affect heat personal stress
past exposure
heath conditions
G6PD
Sickle cell
medications
drugs / alcohol
exercise and fluid intake
lack of sleep
excessive heat stress can cause
heat injury or death
what are the areas aboard ships where heat stress injuries are most common
flight deck
incinerator room
Laundries
Machinery spaces
Sculleries
what are the contributor to heat stress condition
***arduous operations
***ventilation deficiencies
Steam and water leaks
Boiler air casing leaks
missing/deteriorated thermal insulation
weather conditions
a physiological heat exposure limit (PHEL) chart is as set of how many curves
6
the physiological heat exposure limit (PHEL) curve and work rate are est. by who
industrial hygienist / NAVSEA
what are the categories of physiological heat exposure limit (PHEL) curves
Routine operations
Non- routine operations
Evacuation control center exercise
heavy work load
physiological heat exposure limit (PHEL) curve, routine operations is considered as
light work
what is done when physiological heat exposure limit (PHEL) curve, non routine operations is assigned
use next higher PHEL when determining stay time
physiological heat exposure limit (PHEL) curve, non routine is assigned when
increase in normal watch rate and minor equipment casualty
physiological heat exposure limit (PHEL) curve, ECC is assigned when
conducting evacuation control center drills
what physiological heat exposure limit (PHEL) curve, is assigned when conducting a heavy work load
PHEL VI
Define stay time
maximum allowable time personnel may work in heat stress condition at a given time
Define recovery time
minimum of twice the stay time as determined by the PHEL chart or 4 hours whichever is shorter
who must provide heat stress training for newly reporting personnel during indoc
Medical Department representative
what film must the Medical Department representative play
play it cool: heat stress prevention afloat
what are the 5 topics that the Medical Department representative must include in training
causes of heat stress
Hazards
Sx of exposure
heat stress first aid
heat stress monitoring
Heat stress monitors must receive training within how many many weeks
12
what training must a heat stress surveyors complete
