SCALD HAZARDS
Hot Water can cause scalds.
Children, disabled, and the elderly are at the highest risk of
being scalded.
Feel water temperature before bathing or showering.
Scalds from hot water taps can result in severe injuries to
young children.
Scalds can occur when children are exposed directly to hot
water when they are placed into a bath which is too hot.
Always......
Testthetemperatureofthewaterwithyourelbowbeforeplacingyourchildinthebath,alsocarefullyfeel
waterbeforebathingorshoweringyourself.
Supervisechildrenwhenevertheyareinthebathroom.
Makesurethatthehotwatertapisturnedotightly.
Consider.....
Installingchildprooftapcoversorchildresistanttaps(bothapproacheswillpreventasmallhandbeing
