MESQUITE, NV (Leisure Services Dept.) – There are
several ways in which heat can affect a worker. Some of the effects of heat on
the body are more serious than others; thus, it is essential to know the signs
and symptoms of the various heat-related disorders, starting with the most
severe. Please be aware of the
symptoms and stay hydrated at all times!
Heat stroke is the most serious health problem for workers in hot
environments, is caused by the failure of the body internal mechanism to
regulate its core temperature. Sweating stops and the body can no longer rid
itself of excess heat. Signs of heat stroke include:
delirium. loss of consciousness, convulsions or coma
temperature of 106 degree Farenheight or higher
Hot dry skin
which may be red, blotted or bluish
Dizziness & Stomach Cramps.
Victims of Heat Stoke will die unless treated
promptly. While medical help should be called, the victim must be removed
immediately to a cool area and his or her clothing soaked with a cool water. He
or she should be fanned vigorously to increase cooling. Prompt first aid can
prevent permanent injury to the brain and other vital organs.
develops as a result of loss of fluid through sweating when a worker has failed
to drink enough fluids. The worker with heat exhaustion still sweats, but
experiences extreme weakness or fatigue, giddiness, nausea, or headache. The
skin is clammy and moist, the complexion pale or flushed, and the body
temperature normal or slightly higher. Treatment is usually simple: the victim
should rest in a cool place and drink plenty of an electrolyte drink or water.
frequently occur in the extremities. They abruptly appear as a sudden charlie
horse and limit movement of the involved arm or leg. Heat cramps may be
painful, but spontaneously resolve over time. Heat cramps are caused by salt
losses with sweating and are treated with electrolyte-balanced fluids, such as
Gatorade, PowerAde and other electrolyte drinks.
occurs when a worker suddenly faints after standing for a long period. This
fainting results from blood pooling in the legs, causing less blood to be
delivered to the brain. Heat syncope may be treated by lying down or prevented
by moving around while working.
Heat rash, also known as prickly heat, may occur in hot and
humid environments where sweat is not easily removed from the surface of the
skin by evaporation. When extensive or complicated by infection, heat rash can be
so uncomfortable that it inhibits sleep and impedes a workers performance or
even results in temporary total disability. It can be prevented by resting in a
cool place and allowing the skin to dry.
