HEAT STRESS MONITORING PROGRAM Flashcards
WHEN DOES HEAT STRESS BECOME EXCESSIVE?
THE BODY’S CAPABILITY TO ADJUST IS EXCEEDED
RESULTS IN INCREASED BODY TEMP
WHAT ARE THE 4 ENVIRONMENTAL FACTORS THAT CAUSE HEAT STRESS
- THERMAL RADIATION
- VENTILATION
- HUMIDTY
- AIR/SEA WATER TEMP
DEFINE ACCLIMATIZATION
THE ACT OF BECOMING ACUSTOMED TO TEMPATURE OR NEW ENVIROMENT
WHAT IS THE PERIOD FOR ACCLIMATIZATION?
3 WEEKS
WHAT ARE THE PERSONAL FACTORS THAT ARE ASSOCIATED WITH HEAT STRESS?
- PAST HEAT INJURIES
- CURRENT HEALTH
- EXERCISE/FLUID INTAKE
- MEDICATION
- ALCOHOL
- LACK OF SLEEP
- DRUGS
THE MOST COMMON LOCATIONS OF HEAT STRESS CONDITIONS ARE:
- MACHINERY SPACES
- LAUNDRIES
- SCULLERIES
- GALLEYS
- INCINERATOR ROOM
- FLIGHT DECKS
CAUSES AND CONTRIBUTORS TO HEAT STRESS CONDITIONS
- STEAM/WATER LEAKS
- BOILER AIR CASTING LEAKS
- MISSING/DETERIORATED THERMAL INSULATION
- VENTILATION DEFICIENCIES
- WEATHER CONDITIONS
- ARDUOUS OPERATION

- PAINTING
- CLEANING LUBE OIL STRAINERS
HEAT STRESS IS ANY COMBINATION OF
___________ WHICH STRESS THE BODY AS IT ATTEMPTS TO REGULATE
- AIR TEMP
- THERMAL RADIATION
- HUMIDITY
- AIRFLOW
- WORK LOAD
THIS RULE APPLIES TO ASSIGNING THE “NON-ROUTINE OPERATIONS” PHEL CURVE
WHEN WILL YOU USE IT
USE THE NEXT HIGHER PHEL
**WHEN VENTILATION IS DOWN
WHAT ARE ECC EXERCISES
EVACUATION CONTROL CENTER DRILLS
WHAT ARE EXAMPLES OF A HEAVY WORK LOAD
- REPLACING LARGE VALVES
- CLEANING LUBE OIL DUMPS
- DISASSEMBLY OR RESSEMBLY OF LARGE OR HEAVY EQUIPMENT
WHAT IS THE MAXIMUM ALLOWABLE TIME PERSONNEL MAY WORK IN HEAT STRESS CONDITIONS AT A GIVEN WORKLOAD?
STAY TIME (WORK/REST CYCLES)
DEFINED AS A MINIMUM OF TWICE THE STAY TIME AS DETERMINED BY PHEL OR ___ HOURS, WHICHEVER IS SHORTER
RECOVERY TIME
WHAT ARE FUEL COMBUSTION GASES (STACK GAS)
COMBUSTION GASES WHICH MAY ACCUMULATE IN A SPACE DUE TO INADEQUATE VENTILATION OR MACHINERY MALFUNCTION
SIGNS AND SX OF FUEL COMBUSTION GAS
- WATERY EYES
- DYSPNEA
- TINGLING/NUMBESS ON TIPS
- MILD SENSATION OF ALCOHOL INTOXICATION
FUEL COMBUSTION SIGNS AND SX GUIDELINES AND ACTIONS
- REDUCE EXPOSURE LIMITS IF 2 OR MORE SX ARE PRESENT
- NEW PHEL, USE THE RIGHT CHART, OR DIVIDE CURRENT PHEL STAY TIME BY 3
