OSHA 30 Hour Construction Program Practice Test

Which type of burn requires washing the wound with cold water for first aid?

1. First degree

2. Second degree

3. Third degree

4. All types

The correct answer is: First degree

First degree burns, which affect only the outermost layer of skin known as the epidermis, typically present as red and dry with minor pain. Washing the affected area gently with cool or cold water is a recommended first aid treatment to help reduce pain and cool the burn, preventing further damage to the tissue. This cooling method can also aid in the healing process and mitigate swelling. In contrast, second degree burns, which damage the epidermis and part of the underlying layer known as the dermis, may involve blisters and require more specific care, such as protecting the area and possibly seeking medical attention. Third degree burns are the most severe, affecting deeper tissues and often requiring professional medical treatment rather than first aid interventions like cooling with water. Therefore, the best practice for handling a first-degree burn involves the immediate use of cool water to alleviate discomfort and support healing.
