First Aid Training - Effects of heat and cold

Contact to hot materials/surfaces can cause burns or scalds, the longer the contact the more severe the injury will be. Corrosive chemicals can also cause burns. Exposure to extreme heat can cause conditions such sunburn, prickly heat and possibly heatstroke. Extreme cold can also lead to hypothermia and frost bite.
