    Study Notes

    Laboratory Safety Guidelines

    • Flammable materials, such as alcohol, must never be near an open flame to prevent fire hazards.
    • In case of a laboratory fire, immediately notify the instructor for proper handling.
    • Always wear approved eye protection devices (e.g., goggles) when using chemicals, heat, or glassware in the lab.
    • Inform the science instructor if wearing contact lenses to ensure proper safety measures are taken.

    Communication Protocols

    • Clarify any unclear directions or lab procedures with the instructor before proceeding to ensure safety.
    • After completing an experiment, dispose of chemical wastes as directed by the instructor.
    • If an experiment is not finished, discuss it with the instructor for guidance.

    Safe Heating Practices

    • When heating a substance in a test tube, always point the open end away from people to avoid accidents.
    • Use tongs when handling hot glass to minimize the risk of burns or injuries.

    Injury Response Procedures

    • In the event of an injury (e.g., cut, burn), inform the science instructor immediately for assistance.

    Equipment Handling and Care

    • Check glassware for chips or cracks, and ensure it is clean before use by following all instructions carefully.
    • When inserting glass tubing into a rubber stopper, lubricate the tubing, wear protective gear, and twist carefully to avoid breakage.

    Personal Safety Equipment

    • Personal eyeglasses do not offer adequate protection; appropriate eye protection like goggles is essential.
    • Long hair must be tied back securely to prevent entanglement or fire hazards.
    • Avoid wearing loose clothing, dangling jewelry, or sandals in the laboratory for personal safety.
    • Closed-toed shoes are the safest choice for laboratory footwear.

    Laboratory Conduct

    • Practical jokes and horseplay are strictly prohibited to maintain a safe working environment.
    • If equipment malfunctions, stop usage, turn it off, and report the issue to the instructor for further action.

    Chemical Safety

    • Immediately wash any acid splashes on the skin with plenty of water to neutralize effects.
    • After working with chemicals, biological specimens, or lab substances, always wash hands thoroughly with soap and water.
    • Assume all lab chemicals are dangerous, treating them with caution.

    True/False Laboratory Practices

    • Hot glass can appear the same as cold glass; always check before handling.
    • All laboratory chemicals should be treated as hazardous.
    • Unused chemicals should not be returned to original containers; follow disposal regulations.
    • Keep work areas clean and tidy for safety.
    • Never use your mouth to draw liquid into a pipet; use appropriate tools.
    • Removing chemicals or equipment from the lab is forbidden.
    • Chipped or cracked glassware should not be used to prevent accidents.
    • Read all lab procedures thoroughly before beginning any work.
    • Unauthorized experiments are not allowed and must not be conducted.
    • Access to chemical preparation/storage areas should be restricted; entry must be authorized.
    • Laboratory aprons should be worn during all activities for added protection.
    • Do not pick up broken glass with bare hands; use appropriate tools for safe cleanup.
    • Never leave a lit burner unattended to prevent fire risks.
