Which of the following is the safest solution to protect yourself from chemical hazards in the laboratory work environment?

• A. Washing hands only after completing all experiments
• B. Avoiding the use of any chemicals during laboratory work
• C. Wearing appropriate personal protective equipment (PPE) such as lab coats, gloves, and safety goggles
• D. Relying solely on proper ventilation systems

Answer: (C)

Verified step by step guidance

1. Understand that chemical safety in the laboratory involves multiple layers of protection to minimize exposure to hazardous substances.
2. Recognize that washing hands only after completing all experiments is important but insufficient alone, as exposure can occur during the work.
3. Avoiding the use of any chemicals is impractical in a chemistry lab and does not address how to handle chemicals safely when their use is necessary.
4. Relying solely on ventilation systems helps reduce airborne hazards but does not protect against direct contact or splashes.
5. Conclude that wearing appropriate personal protective equipment (PPE) such as lab coats, gloves, and safety goggles provides a direct physical barrier against chemical hazards, making it the safest solution among the options.
