YOU MIGHT WANNA KNOW THIS PT 2 Flashcards
Define Heat Stress
Any combination of air temperature, thermal radiation, humidity, airflow, and work load which stress the body as it attempts to regulate temperature.***
- Environmental Factors Causing Heat Stress
(1) Thermal Radiation **
(2) Ventilation – Airflow *
(3) Humidity – Moisture in the Air
(4) Air/Sea Water Temperature – Intake Valves that allow Sea water/Outside Air to be utilized for cooling for shipboard equipment systems. ***
Which environmental factors can stress the body as it attempts to regulate the body temperature
Humidity and Air Flow
how does acclimation affect the body and how long does it take
The body becomes more efficient in coping with heat stress *
Occurs gradually , usually within 3 weeks or more. *
Personal Factors Associated with Heat Stress ***
(1) Past exposure to heat injuries will affect an individual’s ability to adapt to new situations.**
(a) Decreases the ability to handle heat stress conditions. *
(2) Current health status and use of medications may alter physiological body changes. **
(a) G6PD*
(b) Sickle cell Trait *
3) Exercise and fluid intake (dehydration) **
(4) Medication **
(5) Alcohol Intake **
(6) Lack of sleep **
(7) Drugs ***
- Common Locations of Heat Stress Conditions ***
(a) Machinery Spaces)**
(b) Laundries **
(c) Sculleries (PHEL V)/Galleys **
(d) Incinerator Room *
(e) Flight decks (Thermal Radiation)
- contributors to heat stress conditions aboard ship
(a) Machinery Spaces)**
(b) Laundries **
(c) Sculleries (PHEL V)/Galleys **
(d) Incinerator Room *
(e) Flight decks (Thermal Radiation)
(1) Steam and Water Leaks **
(4) Ventilation Deficiencies **
(6) Arduous Operation ***
- What is the Physiological Heat Exposure Limit (PHEL) Chart
The PHEL curves and work rates are established by the Industrial Hygienist and NAVSEA when a class of ships is designed and placed into service. ***
List the Assignment of PHEL Curves.
(a) Routine operations *
1) Light work*
(b) Non-routine operations*
1) Use the next higher PHEL*
(5) Stay Time (Work/Rest Cycles)
(a) Maximum allowable time personnel may work in heat stress conditions at a given workload. *
(b) not in TG, Each stay time is going to be different.*
(6) Recovery Time **
(a) Is defined as a minimum of twice the stay time as determined by the PHEL chart or 4 hours whichever is shorter. **
(7) Fuel Combustion Gases (Stack gas)
(a) Definition – Combustion gases which may accumulate in a space due to inadequate ventilation or machinery malfunction. ***
- Training requirements for the heat stress for the MDR
The MDR must provide heat stress training for all newly reporting personnel during indoctrination and annually thereafter.*
What does heat stress training need to include
(a) Hazards
(b) Symptoms of Exposure
(c) Heat Stress First Aid
(d) Heat Stress monitoring
(e) Causes of Heat Stress
When do heat stress monitors receive training
Heat Stress Monitors must receive training within 12 weeks upon assignment. ***
T/F: Heat Stress Monitors need to complete Heat Stress surveyor watch station 318 of the safety programs afloat personnel qualifications standards (PQS), NAVEDTRA 43704.*
TRUE
- What are the 4 requirements for reporting heat stress injuries
a. Report using Accident & Injury Report. (LOCAL IN THE SHIP)*
b. Report to the Naval Safety Center should be made using the Web Enabled Safety System (WESS). (LETTING NAVSAFCEN KNOW)c. All Navy heat stress-related injuries should be reported through the Naval Disease Reporting System (NDRS). (LETTING THE WHOLE NAVY KNOW)*
d. Use Medical Event Report format if command does not have access to NDRS.*
Heat requirements of a heat stress survey;
Whats the equation (the )
The heat stress surveyor must check to ensure that the WB < DB; GT ≥ DB; and WB < WBGT < GT ***
Prior to Engineering Casualty or Damage Control Training Team (ECCTT/DCTT) drills, who must be informed
Drill Supervisor must be informed of the current STAY TIMES. *
Heat stress surveys that have reduced Stay Times must be routed through who
the chain and CO notification achieved for work shift alterations to occur. ***
