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.
