affects safety by making it harder to concentrate.
What are the symptoms? The proper treatment?
Heat stress can cause several illnesses.
Heat stroke occurs when the body's temperature control system fails. The skin is hot, usually dry, red or spotted. The body temperature is over 105°F. The victim may be confused, have convulsions, or pass out. Act fast to prevent brain damage or death. Move the victim to a cool and shady area, loosen tight clothing, soak the clothing with water, and fan the head and upper body. Get the person to a hospital right away.
Heat exhaustion is caused by losing too much fluid and electrolytes (salt and other minerals). The skin is clammy and moist. The face may be pale or flushed. The body temperature is normal or a little high.
Heat Cramps are involuntary contractions of muscles principally used during work. They are caused by the loss of sodium and other electrolytes through heavy perspiration and the copious intake of water without appropriate replacement salts. Heat cramps are easily treated with rest and intake of water with electrolytes.
