HYPERTHERMIA INFORMATION
Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above
normal body temperature of 98.6°F (37°C).
The symptoms of hyperthermia include:
Dizziness
Fainting
Drowsiness
Lethargy
Increase in internal body temperature
The effects of hyperthermia include:
Unawareness of impending hazard
Failure to perceive heat
Failure to recognize the need to exit spa
Physical inability to exit spa
Fetal damage in pregnant women
Unconsciousness resulting in a danger of drowning
WARNING –
The use of alcohol or drugs can greatly increase the risk of fatal hyperthermia in hot tubs
and spas.
SAFETY PRECAUTIONS
a. Always enter and exit a spa slowly.
b. Do not use the spa alone.
c. Before entering the spa, always measure the water temperature with an accurate thermometer.
Tolerance of water temperature regulating devices can vary as much as ±5°F (3°C). Always check
the spa water temperature before entering.
d. Since excessive water temperature has a high potential for causing fetal damage during early
months of pregnancy, pregnant or possibly pregnant women should limit spa water temperatures to
100°F (38°C). Always consult your doctor prior to using a spa.
e. Children’s body temperature can increase more rapidly than adults in the same water with elevated
temperatures above 99°F (37°C). Children should spend less time in water above body temperature
than adults.
f. The use of alcohol, drugs, and/or medication before or during spa use may lead to unconsciousness,
hypothermia, serious injury, or the possibility of drowning.
g. Persons suffering from obesity or with a medical history of heart disease, diabetes, high or lower
blood pressure, or circulatory system problems should consult with their physician before using the
spa.
h. Persons on medication should consult with their physician before entering the spa since some
medication may induce drowsiness while other medication may affect heart rate, blood pressure, and
circulation.
i. People with infections, sores, or skin abrasions should not use the spa. Warm and hot water
temperatures may allow the growth of infectious bacteria if not properly disinfected.
j. Test the GFCI (Ground Fault Circuit Interrupter) unit before each use. (Refer to instructions provided
by GFCI manufacturer.)
k. Do not service or repair any equipment without making sure the circuit breaker and/or all power to
the spa is turned off.
l. Cover must be kept on the spa and locked at all times when not in use, especially if children are
present.
