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.
