Study Notes
Safety Equipment and Protocols
- Familiarize yourself with the locations of safety equipment: first aid kit, eyewash station, safety shower, fire extinguisher, and fire blanket.
- Know how to operate all safety equipment; it is essential for responding to emergencies.
- Always handle knives and sharp instruments with tips pointing down and away from the body; cut away from yourself.
- Never attempt to catch falling sharp instruments; grasp only by the handles.
Laboratory Environment
- Work in a well-ventilated area; use fume hoods when dealing with volatile substances or poisonous vapors.
- Avoid placing your head inside fume hoods during operations to prevent inhalation of hazardous fumes.
Personal Conduct and Dress Code
- Conduct yourself responsibly at all times in the lab; stay alert and cautious.
- Long hair must be tied back, and dangling jewelry should be secured to avoid hazards.
- Wear proper footwear that fully covers the foot; no sandals allowed.
- Laboratory aprons should be worn during activities to protect clothing and skin from spills.
Chemical Handling and Disposal
- Dispose of chemical waste properly; only designated substances can go down the sink.
- Solid chemicals and insoluble materials must be disposed of in the designated waste containers.
General Laboratory Rules
- Read and follow all written and verbal instructions carefully; seek clarification if needed.
- Never work alone; a teacher must be present.
- Do not touch equipment or materials upon entering the lab until instructed.
Accidents and Emergencies
- Immediately report any accidents or injuries to the instructor, regardless of how minor they may seem.
- Initiate a "Code one" call if you or a partner are injured to alert the instructor.
- For chemical splashes in eyes or on skin, flush with running water from the eyewash station or safety shower for at least 20 minutes.
Experimentation Guidelines
- Perform only experiments authorized by the instructor; unauthorized experiments are strictly prohibited.
- Monitor experiments personally and remain at your assigned laboratory station during procedures.
