One of the most common causes of burn injuries is scald injury. Hot water scalds is a common cause of scald injury in which a short exposure time can result in severe burns depending on the water temperature. Most scald burns happen in the home from exposure to hot water in the sink, showers or bathtubs. Scald burns can also happen at restaurants and other places. Scald burns can happen to anyone, the severity depends on the temperature of the liquid and the duration of exposure.
Scald burns can happen to anyone but there is a vulnerable population which can be affected that includes young children, elderly people and people with disabilities. Many people are unaware that it needs a short exposure period to hot tap water to cause serious burns. People at high risk of developing scald burns are:

- Elderly people have thinner skin leading to deeper and more severe burns. Elderly people may also have other medical conditions that make them more liable to fall in the bathtub as well as decreased sensation of heat and poor microcirculation leading to slow release of heat from the burned tissue.
- People with physical and cognitive disabilities
- Crowded families and families with low socioeconomic status
- Single parent and parents with poor education.
