Tips for Hazardous Chemical Handling in Laboratory

1. Know the Chemical Hazards

• Read Safety Data Sheets (SDS) before use.

• Understand toxicity, flammability, reactivity, and environmental hazards.

2. Use Proper Personal Protective Equipment (PPE)

• Wear lab coat, chemical-resistant gloves, safety goggles, and closed-toe shoes.

• Use face shields and respirators for highly hazardous chemicals.

3. Work in Well-Ventilated Areas

• Handle volatile or toxic substances in fume hoods or ventilated enclosures.

• Keep sash height low for better protection.

4. Label and Store Chemicals Properly

• Use clear labels with chemical name, hazard symbols, and date received.

• Store acids, bases, flammables, and oxidizers separately.

5. Avoid Direct Contact

• Never touch chemicals directly — use pipettes, tongs, or spatulas.

• Do not pipette by mouth (only mechanical pipetting devices).

6. Prevent Spills and Leaks

• Keep work areas uncluttered.

• Use spill trays for liquid chemicals.

• Inspect containers regularly for leaks.

7. Follow Safe Mixing Practices

• Add acid to water (never water to acid) to prevent violent reactions.

• Avoid incompatible chemical mixing without prior knowledge.

8. Dispose of Waste Safely

• Segregate hazardous chemical waste from regular trash.

• Follow approved disposal procedures — never pour down the drain unless permitted.

9. Have Emergency Equipment Ready

• Ensure easy access to eyewash stations, safety showers, and fire extinguishers.

• Keep first aid kits stocked.

10. Training and Documentation

• Attend chemical safety training regularly.

• Document incidents, near-misses, and corrective actions.

✅ Golden Rule:
Think before you touch — know what you’re handling, and take all precautions before starting work.
