Why is wearing PPE during field operations important?

• A. PPE is optional during field operations.
• B. PPE reduces injury risk and prevents contamination of evidence.
• C. PPE is required only for hazardous environments.
• D. PPE increases time and is not necessary.

Answer: (B)

Wearing PPE in field operations protects you and helps keep evidence uncontaminated. Gloves, eye protection, coveralls, masks, and other equipment create barriers against injuries from sharp objects, chemical splashes, biological hazards, and environmental conditions, while also preventing transfer of trace materials between the scene and you. The right PPE is chosen based on the hazards you expect, so you might wear gloves, eye protection, respirators, or protective clothing as needed. PPE isn’t optional or limited to obviously dangerous environments; even routine field work carries risks of exposure or contamination, and using PPE keeps you safe and preserves the integrity of the evidence. Any increase in time to put on PPE is small compared to the benefits of reduced injuries and cleaner, more reliable results.
