Study Notes
Laboratory Safety Guidelines
- Maintain cleanliness and organization in work areas at all times.
- Turn off fume hoods and electrical equipment when not in use.
- Bring only necessary laboratory materials; keep personal items stored away.
- Ensure aisles are clear and push chairs under desks when not in use.
Chemical Handling and Disposal
- Never taste or smell chemicals unless explicitly instructed.
- Use proper techniques for wafting chemical vapors as demonstrated.
- Solid chemicals and materials like filter paper must be disposed of in designated waste containers, not in sinks.
- Always check labels of chemical bottles and waste containers twice before use or disposal.
Student Conduct in the Laboratory
- Never work alone; an instructor must always be present in the lab.
- Proper dress code includes tied-back long hair, no dangling jewelry, and shoes that cover the feet. Sandals are not allowed.
- Follow all written and verbal instructions carefully; seek clarification from the instructor if needed.
- Use rubber bulbs or pipet pumps instead of mouth suction for filling pipets.
Equipment and Glassware Safety
- Read labels and equipment instructions thoroughly before use.
- Avoid returning unused chemicals to their original containers.
- Do not immerse hot glassware in cold water as thermal shock may cause shattering.
Emergency Preparedness
- Know the location of safety equipment and emergency exits.
- Be aware of fellow students who wear contact lenses for emergency responses related to eye exposure.
Agreement and Responsibilities
- Students must read and agree to follow all safety rules outlined in the contract for the safety of themselves and others.
