WARNING – The following "Safety Rules for Hot Tubs" recommended by the U.S. Consumer
Product Safety Commission should be observed when using the spa.
1. Spa or hot tub water temperatures should never exceed 104°F [40°C]. A temperature of 100°F
[38°C] is considered safe for a healthy adult. Special caution is suggested for young children. Pro-
longed immersion in hot water can induce hyperthermia.
2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness, which
could lead to unconsciousness and subsequently result in drowning.
3. Pregnant women beware! Soaking in water above 100°F [38°C] can cause fetal damage during the
first three months of pregnancy (resulting in the birth of a brain-damaged or deformed child). Preg-
nant women should adhere to the 100°F [38°C] maximum rule.
4. Before entering the spa or hot tub, users should check the water temperature with an accurate ther-
mometer; spa or hot tub thermostats may err in regulating water temperatures by as much as 4°F
(2.2°C).
5. Persons taking medications, which induce drowsiness, such as tranquilizers, antihistamines or anti-
coagulants, should not use spas or hot tubs.
6. If the pool/spa is used for therapy, it should be done with the advice of a physician. Always stir pool/
spa water before entering the pool/spa to mix in any hot surface layer of water that might exceed
healthful temperature limits and cause injury. Do not tamper with controls, because scalding can
result if safety controls are not in proper working order.
7. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure
problems should obtain a physicians advice before using spas or hot tubs.
8. 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: drowsi-
ness, lethargy, dizziness, fainting, and an increase in the internal temperature of the body.
The effects of Hyperthermia include:
1. Unawareness of impending danger.
2. Failure to perceive heat.
3. Failure to recognize the need to leave the spa.
4. Physical inability to exit the spa.
5. Fetal damage in pregnant women.
6. Unconsciousness resulting in danger of drowning.
