Get out of the spa or hot tub immediately if you experience nausea, dizziness or fainting. These are signs of hyperthermia which can be fatal. Cool your body with cold towels or a cool shower. Call a doctor or 9-1-1 if the symptoms do not go away.
Keep the water temperature in your spa below 104°F (40°C). Age or health conditions (especially pregnancy) may require a lower temperature. Consult your physician for more information.
Never use the spa or hot tub if you are using alcohol or drugs. The combination of hot water and alcohol and/or drugs can cause dizziness, falling, unconsciousness or a heart attack.
Make sure your spa or hot tub has dual suction outlets (read Pump Suction for more information). All tub suction fittings should be certified to meet the current ASME/ANSI Standards that apply.
Never alter the electrical cord or plug on the spa system.
Never use an extension cord to connect a spa system to an existing electrical outlet. A spa system must operate from a GFCI (ground fault circuit interrupter) protected circuit or outlet. If in doubt, consult a licensed electrician.
