How can a QS minimize worker exposure during cleanup and maintenance?

• A. Use PPE only
• B. Follow decontamination procedures
• C. Use PPE; Follow decontamination procedures; Minimize direct contact; and avoid cross-contamination with equipment washing
• D. Delay cleanup until no longer necessary

Answer: (C)

Minimizing exposure during cleanup combines multiple protective steps to reduce risk at every point of contact. Wearing appropriate personal protective equipment provides a barrier between the worker and contaminants, but it doesn’t remove contamination or stop it from transferring. Decontamination procedures are essential because they actively remove residues from skin, clothing, and equipment, lowering the amount of contaminant a worker might absorb or come into contact with. Reducing direct contact further lowers exposure by limiting opportunities for contaminants to transfer to skin or mucous membranes, and by using tools or long-handled instruments to avoid touching contaminated surfaces. Preventing cross-contamination through careful washing and handling of equipment ensures that residues aren’t moved from dirty areas to clean ones or to other surfaces and gear. Putting these controls together creates a safer, more effective cleanup strategy than relying on any single measure alone. Delaying cleanup leaves hazards in place, increasing exposure risk, so prompt, integrated controls are preferred.
