Which activity corresponds to step 7 of standard precautions in hazardous materials response?

• A. Notifying family
• B. Securing payroll records
• C. Stocking supplies
• D. Observing standard precautions during decontamination

Answer: (D)

Standard precautions are the baseline protective practices used to prevent exposure to contaminants at hazardous materials incidents. Step seven focuses on applying these precautions during decontamination because this is a high-risk phase where contaminants can spread if PPE is breached or if surfaces and equipment are not handled properly. Keeping the same protective measures during decon—wearing the appropriate PPE, following proper doffing and decon procedures, managing contaminated runoff safely, and performing hand hygiene—protects responders and others from cross-contamination as materials are removed.

Tasks like notifying family, securing payroll records, or stocking supplies fall outside the safety-focused decontamination process; they are administrative or logistics activities and do not directly address protecting people from exposure during decon. Observing standard precautions during decontamination is the action that best aligns with the goal of preventing spread of contaminants and safeguarding responders.
