Tips to Prevent Scalds

To reduce the risk of scald burns, consider these safety tips:
  • Adjust hot water heater so that the household water temperature delivered from all faucets will not exceed 49°C (120°F). 
  • Replace bath faucets and shower heads with scald-guard equipment. These products keep water that exceeds 49°C (120°F) from coming through the faucets. The water is reduced to a trickle until the taps are manually adjusted to a safe temperature.
  • Have mixing valves installed at various points of the water lines to affect baths, showers and sinks. This is the best option for tenants in multi-unit dwellings equipped with a central hot water tank.
  • When cooking, turn pot handles to the back of the stove. If possible, only use the back elements.
  • Use spill-resistant cups with a lid for hot liquids.
  • Be aware that soup, coffee, tea and hot chocolate can cause serious burns.
  • Keep appliances and cords out of reach
  • Do not allow small children in your cooking area. It is easy to fall over a small child when carrying dangerously hot pots, pans or cups full of food or liquid.
  • Microwaves can be dangerous. Food warmed in a microwave can be heated unevenly, leaving pockets of extremely hot temperatures.
  • Prevent hot food or liquid pull-overs by using place mats instead of tablecloths.
  • Never carry your child while cooking.
  • Never drink hot liquids while breastfeeding your child.
  • Provide constant close supervision when around burn hazards
  • Use a barrier around the fireplace or in front of the glass
  • Childproof bathrooms and laundry room doors
  • Always supervise children in the bathroom, 65 per cent of all scald burns occur in the bathroom. 

Time/temperature interaction associated with scald burns

The American Journal of Pathology, (Mortiz & Henriqures 1947; 23:695-720) reports the time it would take to receive a severe burn from things we might often encounter as follows:
