1. Answer concisely each question <br /> Responses are short, precise, and accurate for quick reference. <br /><br />1. **Purpose of MSDS**: Provides detailed information on chemical properties, hazards, handling, storage, and emergency measures. <br />2. **Chemical Spill Handling**: Alert others, use spill kits, wear PPE, ventilate area, contain and clean per protocol. <br />3. **Typical PPE**: Lab coat, safety goggles, gloves; sometimes face shield, closed shoes. <br />4. **Chemical Storage Precautions**: Store by compatibility, label clearly, use ventilated cabinets, avoid heat/sunlight. <br />5. **Flammable Material Management**: Store in flammable cabinets, keep away from ignition sources, use in fume hood if volatile. <br />6. **Response to Chemical Exposure**: Remove from exposure, flush with water, seek medical help, report incident. <br />7. **Signs of Exposure/Poisoning**: Dizziness, nausea, headache, rash, burns, trouble breathing. <br />8. **Safe Waste Disposal**: Segregate by type, label waste containers, follow hazardous waste protocol. <br />9. **First Step in Accident**: Ensure safety, stop the hazard, and alert supervisor immediately. <br />10. **Importance of Labeling**: Prevents misuse, ensures safe handling, storage, and disposal. <br />11. **Hazardous Substance Protocols**: Use PPE, follow SOPs, work in fume hood, monitor conditions, dispose properly. <br />12. **Prevent Cross-Contamination**: Clean surfaces, dedicate equipment to tasks, change gloves often. <br />13. **Safe Chemical Transport**: Use secondary containment, secure containers, avoid carrying large amounts. <br />14. **Inspection of Safety Equipment**: At least monthly; eyewash and showers checked weekly. <br />15. **Unlabeled Chemical Action**: Do not use; treat as hazardous waste and dispose per protocol. <br />16. **Good Housekeeping Importance**: Reduces accidents, improves workflow, ensures compliance. <br />17. **Role of Safety Officer**: Enforce safety policies, conduct training and inspections, manage incidents. <br />18. **Fire Extinguishers in Chem Lab**: Class ABC and Class D (for metal fires); CO₂ for electrical/liquid fires. <br />19. **Monitoring Reactions for Safety**: Use sensors, control temperature/pressure, observe color or gas changes. <br />20. **Importance of Reporting Near Misses**: Prevents accidents by addressing hazards before they cause harm.
