    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.
    • Cooperation with instructors and classmates is essential for maintaining a safe laboratory environment.
