 DANGER
ALWAYS hand test the incoming water temperature and the water temperature in 
the tub before immersing the resident. Failure to do so may result in a scalding injury.
The causes, symptoms, and effects of hyperthermia may be described as follows: 
Hyperthermia occurs when the internal temperature of the body reaches a level 
several degrees above the normal body temperature of 98.6° F. The symptoms of 
hyperthermia include an increase in the internal temperature of the body, dizziness, 
lethargy, drowsiness, and fainting. The effects of hyperthermia include:
•Failure to perceive heat
•Failure to recognize the need to exit the spa or hot tub
•Unawareness of impending hazard
•Fetal damage in pregnant women
•Phyical inability to exit the spa or hot tub
•Unconsciousness resulting in the danger of drowning
The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyper-
thermia.
