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.
