Answer: (C)

Verified step by step guidance

1. Understand that personal protective equipment (PPE) is designed to protect you from potential chemical hazards in the laboratory environment.
2. Recognize that chemical hazards can be unpredictable and may occur at any time, not just during accidents or when working with highly toxic chemicals.
3. Learn that best safety practices require wearing PPE at all times when handling chemicals or working in the laboratory to minimize risk.
4. Consider that waiting for instructions or only reacting to spills is unsafe because exposure can happen without warning.
5. Conclude that the safest and most responsible approach is to wear PPE continuously while in the lab to ensure maximum protection.
