Most scalds result from exposure to high-temperature water, such as tap water in baths and showers or cooking water, or from spilled hot drinks, such as [[coffee]].
Scalds can be more severe when steam impinges on the naked skin, because steam can reach higher temperatures than water and transfers [[latent heat]] by condensation. On the other hand when clothes are soaked with hot water the heat transfer is often of a longer duration since the body part cannot be removed from the heat source as quickly.
The temperature of tap water should not exceed {{convert|38|-|45|°C|°F}} to prevent discomfort and scalding.<ref>German and European norm DIN EN 806-2 asks for a maximum of {{convert|45|°C|°F}} in public buildings. The temperature in care homes and childcare is not to exceed {{convert|43|°C|°F}} with a maximum of {{convert|38|°C|°F}} in showers. The German guideline VDI 3818 generally recommends {{convert|40|°C|°F}} for public bathrooms and toilets.</ref> However, it is necessary to keep warm water at a temperature of {{convert|55|–|60|°C|°F}} to inhibit the growth of [[legionella]] bacteria.
Water at {{convert|60|°C|°F}} can induce scalding injuries in less than 3 seconds, while it takes 10 seconds to get an injury at {{convert|57|°C|°F}} and 1.5 to 2 minutes in {{convert|52|°C|°F}} hot water.<ref>FAQ Thermostatic mixing valves – [http://www.esbe.eu/de/en/support/faq/faq-thermostatic-mixing-valves?qid=9Ac_4doDcU-RUEehh-b7FA Why is it important to have a thermostatic mixing valve?], ESBE AB, Sweden</ref>
Scalds are generally more common in children, especially from the accidental spilling of hot liquids.
