Which of the following is a correct precaution for personnel handling hazardous waste?

• A. Wear gloves
• B. Wear laboratory coats
• C. Wash hands frequently
• D. All of the above

Answer: (D)

Handling hazardous waste safely relies on layered protection that covers different routes of exposure. Wearing gloves creates a barrier against skin contact with hazardous materials. A lab coat protects skin and clothing from splashes and helps prevent spreading contaminants outside the work area. Washing hands frequently removes any residues that could be transferred to your face, mouth, or other surfaces, and helps prevent ingestion or transfer when removing gloves or touching objects. Because each precaution addresses a separate risk, using all three together provides the best protection. Remember to remove gloves and lab coat carefully and wash hands after handling waste.
