Frequently Asked Question?
1. Why is it important to store hazardous and poisonous chemicals in a locked cabinet with proper labeling?
Answer: Storing these chemicals securely prevents unauthorized access and accidental exposure, protecting both people and the environment. Clear labeling ensures everyone knows the potential hazards and can handle them appropriately.
2. What specific personal protective equipment (PPE) should be used when handling hazardous and poisonous chemicals?
Answer: The specific PPE depends on the chemical, but generally includes acid-proof gloves, safety goggles, and potentially a lab coat, face shield, or respirator. Refer to the Safety Data Sheet (SDS) for detailed recommendations.
3. Why is it important to use a fume hood when preparing solutions of hazardous chemicals?
Answer: Fume hoods provide ventilation to remove harmful fumes and vapors, protecting the user from inhaling dangerous substances.
4. What is the purpose of using a suction bulb while pipetting hazardous solutions?
Answer: A suction bulb prevents mouth pipetting, which can accidentally draw the solution into the user’s mouth, leading to ingestion and potential poisoning.
5. How should you handle spills of hazardous chemicals?
Answer: This typically involves containing the spill with absorbent materials, notifying appropriate personnel, and safely disposing of contaminated materials.
6. Why is it important to keep flammable liquids and solvents separate from flames and sparks?
Answer: Flammable substances can easily ignite, causing fires and explosions. Keeping them away from heat sources minimizes the risk of accidents.
7. What information does a Material Safety Data Sheet (MSDS) provide about hazardous chemicals?
Answer: The MSDS contains vital information about the chemical’s physical and health hazards, safe handling procedures, spill response, and first-aid measures. Having readily available MSDSs is crucial for ensuring laboratory safety.
Bonus Question:
8. What additional safety measures should be considered when working with hazardous chemicals?
Answer: Depending on the specific chemicals and procedures, additional measures could include:
- Working with a partner for accountability and emergency assistance.
- Being aware of emergency evacuation procedures.
- Washing hands thoroughly after handling chemicals.
- Properly disposing of waste chemicals and contaminated materials.
