    Study Notes

    Safety Guidelines in the Laboratory

    • Flammable materials, such as alcohol, must never be used near an open flame.
    • In the event of a laboratory fire, promptly notify your instructor instead of attempting to extinguish it yourself.
    • Always wear approved eye protection devices (goggles) when using chemicals, heat, or glassware.
    • Contact lens wearers should remove lenses before starting a lab experiment to ensure safety.

    Procedure Compliance

    • Clarify any unclear directions or lab procedures by asking the instructor before proceeding.
    • Chemical waste must be disposed of as per the instructor's directions after completing an experiment.
    • Discuss incomplete experiments with the instructor instead of trying to finish them independently.

    Safe Practices

    • When heating a test tube, always point the open end away from yourself and others.
    • Use tongs when handling heated glassware to prevent burns.
    • Report any injuries (cuts, burns, etc.) to the science instructor immediately.

    Equipment Handling

    • Inspect glassware for chips or cracks before use, and clean any dirty glassware as necessary.
    • When inserting glass tubing into a rubber stopper, lubricate the tubing and use appropriate protection like gloves.

    Protective Gear and Attire

    • Personal eyeglasses provide equivalent protection to safety glasses but not to splashproof goggles.
    • Long hair must be secured away from the experiment for safety.
    • Loose clothing, dangling jewelry, and sandals are prohibited in the laboratory for safety reasons.

    Safety Rules and Emergency Protocol

    • Horseplay is strictly forbidden in lab environments.
    • If equipment malfunctions, turn it off and inform the science instructor.
    • Rinse skin immediately with plenty of water if acidic substances splash onto it.

    Hygiene and Cleanliness

    • Always wash hands thoroughly with soap and water after handling chemicals or biological materials.
    • Laboratories should be kept clean and tidy for a safe working environment.

    True or False Safety Statements

    • Treat all chemicals in the lab as potentially dangerous.
    • Return unused chemicals to their original containers is not allowed.
    • Always follow the rule: no unauthorized experiments are permitted.
    • Laboratory aprons should be worn during all activities for protection.

    General Lab Awareness

    • Hot glass can appear identical to cold glass; assume all glass is hot until confirmed otherwise.
    • Never use chipped or cracked glassware as it poses a safety risk.
    • Entering the chemical preparation area requires permission and should not be done without supervision.
