Climate Conditions Flashcards
Core Temperature
The temperature that the human body tries to maintain internally (98.6 degrees Fahrenheit/36 degrees Celsius)
Rhabdomyolysis
rab-dow-my-aa-luh-sis (Rabdo)
A medical condition, sometimes caused by heat stress and prolonged physical exertion, in which muscle fibers rapidly break down, die and release electrolytes and proteins into the bloodstream.
Heat-Related Illness
Illness that occurs when there is an increase in the worker’s core body temperature above healthy levels.
A situation where too much heat is absorbed by a person, a plant or an animal and causes stress, illness or even death.
Heat Stress
The overall physiological response dedicated to dissipating excess heat from the body characterized by increased heat rate and sweating.
Heat Strain
Skin irritation caused by excessive sweating where excessive moisture and sweat obstructs sweat ducts and forms itchy and painful red pimple or blister clusters and skin lesions.
Heat Rash
Heat Syncope
Fainting that occurs after a period of standing or sudden rising from a sitting position.
Spastic contractions and pain in voluntary muscles mainly in the arms, legs, or torso due to the body’s dehydration and depletion of salts from excessive sweating.
- Heat Cramps
A condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious heat illness can occur if your body temperature rises to 104 degrees Fahrenheit (40 degrees Celsius) or higher.
Heat Stroke
Heat Exhaustion
Heat illness often accompanied by elevated core body temperatures around 100.4 to 102.2 degrees Fahrenheit, (38 to 39 degrees Celsius). Symptoms may include headache, nausea, dizziness, fatigue, weakness, thirst, heavy sweating, irritability, and a decreased urine output.
WBGT
Wet Bulb Globe Temperature; measurements used to determine when heat exposure hazards are present in the workplace.
Natural Wet Bulb Thermometer
Thermometer that measures sweat’s effectiveness in cooling the body. It represents increased sweat evaporation potential when wind speed increases and decreased sweat evaporation potential when there is more moisture in the air.
Dry Bulb Thermometer
Thermometer that measures temperature without impact from other factors.
Black Globe Thermometer
Thermometer that measures the radiant energy from direct sunlight or other sources, like machinery and hot structures near the workplace.
WBGT Meter
The wet-bulb globe temperature is a type of apparent temperature used to estimate effect of temperature, humidity, wind speed, and visible and infrared radiation on humans.
