Final answer:
The first step in treating a burn from a dry chemical is to brush off the chemical powder. Then, rinse with cool water and seek medical attention for severe burns or signs of infection.
Step-by-step explanation:
For the treatment of a burn caused by a dry chemical, the first step you should take is to brush off the chemical powder. This is essential before flushing the area with water, as water can sometimes react with certain chemicals, causing further skin damage or creating a thermal reaction that might worsen the burn. After carefully removing any residual dry chemical, you can then proceed to rinse the area with cool water. Seeking medical attention is also important, especially if the burn is severe or covers a large area of the skin.
It's crucial to follow instructions carefully when handling flammable chemicals to avoid accidental burns or fires. Always work in a well-ventilated area, and be aware of the proper safety protocols, such as using fire-resistant clothing when necessary. In the case of a chemical burn, monitoring for signs of infection, such as increased redness, swelling, and pain, is also critical.
