Which statement best describes proper decontamination practice?

• A. Lubricate equipment with petroleum products after cleaning
• B. Detergent wash and rinse with approved decontaminants
• C. Rinse with water only
• D. Use solvents to clean all surfaces

Answer: (B)

Proper decontamination starts with removing the soil and contaminants from the equipment using a detergent wash, which helps lift and emulsify residues. After washing, rinse to remove loosened material, then apply an approved decontaminant that is appropriate for the contaminant and the surface, following the product’s instructions. This combination ensures contaminants are effectively reduced or neutralized and surfaces are safe for future use. Using petroleum products after cleaning can leave problematic residues; rinsing with water alone often doesn’t remove all contaminants; and solvents can be hazardous or unsuitable for many surfaces. Detergent washing followed by an approved decontaminant (with proper contact time and rinsing) provides the reliable, compliant approach.
