Using certain prescription drugs can cause drowsiness, dehydration, decreased heart rate and other issues in hot water. Talk to your doctor before entering a spa to prevent adverse reactions.
Those with health issues like heart disease, diabetes, high/low blood pressure should check with a doctor before spa use.
Be prepared by learning CPR and first aid, especially in households with children or those with health issues.
Long soaks in too-hot water can cause overheating and other medical complications. The U.S. Consumer Product Safety Commission (CPSC) has found that 100-102°F is a safe temp for most adults. Because of this, most tubs are set with a 104° max temp.
Limit spa sessions to 15 minutes, with less time when soaking at hotter temperatures. Dizziness and nausea are signals that you have been soaking too long, and you should exit the spa.
Thermostats can vary by a few degrees, so your top-side control reading may be slightly higher than the spa water. Test water independently from your spa controls using a floating thermometer.
Pregnancy, Children and Infants
Children have more sensitive skin and are prone to overheating, so use caution when introducing them to the hot tub. The CSPC recommends water no more than 95°F for kids over five. Turn down the temperature and give the spa time to cool before children enter. Check with your pediatrician before bringing children and infants five and under into a hot tub.
Full submersion increases the risk of heat stroke or entrapment danger. Have children sit in higher “cool-off” seats or use a booster seat to stay well above the water line. Restrict soaking time between 5-10 minutes.
Do not leave children unattended in any amount of water, hot or otherwise, even if your child can swim.
Expectant mothers should use extreme caution with spa use. Fully submerging in hot water raises body temperature, and can potentially harm the baby. Before entering a hot tub, pregnant women should consult a physician and follow their advice to avoid possible complications.
Limb entrapment or entangled hair can occur with dangerous older spa suction covers. Jet pumps create a powerful suction that may pull hair or clothing toward the suction cover. This poses a significant drowning risk to children with heads underwater.
Federal regulations require all spa suction covers to be VGB compliant. Passed in 2008, this act aimed to prevent drowning in spas and pools. Have a professional evaluate your spa if older than 2008, and replace outdated covers with VGB compliant suction fittings.
These covers reduce suction when blockage occurs, but apply caution. All spa users, especially kids, must keep their heads above water and away from any suction covers.
Hot Tub Wiring
For 240V spas, the National Electrical Code requires an approved manual disconnect device. This must be located at least 5 ft. away, and within line of sight of the spa for safety. Make sure that your hot tub’s electrical system is properly wired, grounded, and protected by a GFCI.
Plug-and-Play spas should be plugged directly into a dedicated outlet to avoid overloading the circuit. If your spa does not include an in-line GFCI cord, have a licensed electrician install a 15-amp GFCI protected outlet. Never use an extension cord to plug in a spa.
Spas should be placed at least 25 feet from power lines and at least 5 feet from any cords. Provide adequate solar or battery powered lighting at ground level, especially if using the spa at night.
Do not bring any corded electrical device, like a radio, near the spa to avoid risk of electrocution. If any plugged-in item falls into the spa water, unplug it instead of reaching into the water to retrieve it. Consider using a battery-operated Bluetooth speaker instead.
When using wet/dry vacuums or other electrical appliances to clean a drained spa, use extreme caution to avoid electrocution. Do not stand in a puddle of water, always have dry hands and feet, and wear rubber-soled shoes. All outlets within 10 feet should be GFCI protected.
Hot tub covers not only insulate, but protect against unwanted entry by children and animals. They should be in good condition with functional straps and locks. If your latches are broken or missing, replacement cover locks can easily be installed on an existing cover.
Keep the cover secured snugly when the spa isn’t in use and instruct children not to play on the cover. Additional tie-down straps provide extra security.
Old, waterlogged covers are often too heavy to lift safely, and can grow mold and mildew.
Replace waterlogged or damaged covers with a spa cover that meets the ASTM safety standards.
Patio Area, Safety Rails and Steps
After a soak, wet feet and wobbly legs can make it difficult to exit the spa. Install a sturdy handrail or two and non-slip spa steps to prevent falls.
Maintain wood decking with waterproof sealant and restore splintered or slippery boards. Non-skid mats around the spa provide additional security against accidents.
Not only is using the spa more fun with a partner, but is much safer. Accidents and emergencies can easily be avoided with another adult. Children should never be left alone in any spa or pool for even a moment.
