Front 1

Heat Stress

Back 1

The net heat load to which a worker may be exposed from the combined contributions of metabolic heat, environmental factors, and clothing requirements.

Front 2

Heat Strain

Back 2

The overall physiological response resulting from heat stress

Front 3

Cold Stress

Back 3

Environmental and/or personal conditions that tend to remove body heat and decrease body temperature

Front 4

Transfer takes place though the following

Back 4

Radiation, Convection, Conduction, Evaporation

Front 5

Metabolism

Back 5

The flow of energy and the associated physical and chemical changes constantly taking place in the billions of cells that make up the body

Front 6

Radiation

Back 6

Solid bodies of different temperatures have a net heat flow from the hotter surface to the cooler surface by electromagnetic radiation

Front 7

Convection

Back 7

The transfer of heat in a moving fluid or air

Front 8

Conduction

Back 8

When two solid bodies are in contact, heat will flow from the warmer body to the cooler body

Front 9

Evaporation

Back 9

The removal of heat from an object by the vaporization of liquid

Front 10

Heat-Realated Disorders

Back 10

Heat Illness, Heat Stroke, Heat Exhaustion, Heat Syncope, Heat Cramps, Heat Rash, Sunburn

Front 11

Heat Illness

Back 11

All embracing teram and applies to an individual who becomes incapacitated as the result of a rise in core body temperature

Front 12

Heat Stroke

Back 12

The most serious heat-related disorder. It occurs when the body's temperature regulation fails and is unable to get rid of excess heat and the body temperature rises to critical levels

Front 13

Heat Exhaustion

Back 13

Fainting - Pooling of blood in the legs and skin

Front 14

Heat Cramps

Back 14

Caused by electrolyte imbalance and causes muscle pains or spasms

Front 15

Heat Rash

Back 15

AKA Prickly heat - Prolonged, uninterrupted sweating and inadequate hygiene practices

Front 16

Sunburn

Back 16

Reducing the ability to sweat, degrading performance and increasing the risk of heat casualties

Front 17

Hypothermia

Back 17

Serious health condition - Heat loss exceeds heat production

Front 18

Frostbite

Back 18

Skin/tissue freezes - Commonly occurs in the extremities at temperatures of 30 F or lower

Front 19

Frostnip

Back 19

Milder cold injury that does not cause tissues loss. Reversible freezing, numbness and whiteness of the skin, possible itching or pain

Front 20

Trench Foot

Back 20

Immersion Foot - exposed to cold we conditions for prolonged periods of time

Front 21

Chilblain

Back 21

Superficial cold injury, most common on the fingerers ears cheeks toes and exposed shins

Front 22

Raynaud's Disorder

Back 22

Affects arteries, marked by brief episodes of vasospasm or narrowing of the blood vessels

Front 23

Heat Stress Engineering Controls

Back 23

Dilution Ventilation, Active Cooling, Shielding

Front 24

Dilution Ventilation

Back 24

Brings in a supply of cooler air from another area and reduces the temperature in the work area by diluting the hot air with cooler air

Front 25

Active Cooling

Back 25

Mechanical refrigeration, evaporative cooling, or a water chiller is used to reduce the temperature

Front 26

Shielding

Back 26

Insulated or reflective barrier between the source and the receiver can interrupt the pathway of heat

Front 27

Heat Stress - Administrative Controls

Back 27

Acclimatization, Pace of Work, Sharing Work, Scheduling of Work, Work Times, Self-Determination and Personal Monitoring, Fluid Replacement, Diet, Life-Style and General Health, Awareness Training

Front 28

Acclimatization

Back 28

10-14 days - A series of physiological adjustments that occur when an individual is expose to a hot climate

Front 29

Pace of Work

Back 29

Slow down the pace of work

Front 30

Sharing Work

Back 30

Distribute the work

Front 31

Scheduling of Work

Back 31

Scheduling nonessential work to cooler times of the day

Front 32

Heat Stress - PPE

Back 32

Circulating Air Systems, Circulating Water Systems, Ice Garments, Reflective Clothing

Front 33

Circulating Air Systems

Back 33

Circulating air under the clothing and around the torso

Front 34

Circulating Water Systems

Back 34

A system that circulates cool water though tubes and channels around the body

Front 35

Ice Garments

Back 35

Removes body heat from the skiing by the use of packets of ice

Front 36

Reflective Clothing

Back 36

Best suited for sources of high radiant heat
