Which of the following is a key step in HAZMAT decontamination?

• A. Use of water only
• B. Immediate treatment of injuries
• C. Removal of contaminated clothing
• D. Returning to the incident area

Answer: (C)

One of the fundamental steps in HAZMAT decontamination is the removal of contaminated clothing. This is crucial because contaminated clothing can continue to adhere toxic substances to the skin and may prolong exposure to hazardous materials. By quickly and thoroughly removing clothing that has been in contact with hazardous substances, responders can significantly reduce the risk of chemical burns, absorbance of toxins, or secondary contamination of the skin and eyes. This step makes way for further decontamination procedures, such as rinsing off the skin with water, and plays a vital role in protecting the health and safety of the individuals being decontaminated.

Other steps, such as treating injuries or using water, are important but do not address the immediate need to prevent further contamination or exposure from clothing. Returning to the incident area would contradict the principles of safety during a HAZMAT incident, as it increases the risk of further exposure to hazardous conditions. Hence, the removal of contaminated clothing is a primary action that must be performed to ensure effective decontamination.
