Study Notes
Purpose of Safety Rules
- Laboratory activities involve hazardous chemicals, making safety a priority for everyone involved.
- A student safety contract outlines essential rules to be followed at all times.
- Two copies of the contract must be signed - one for participation and one for personal reference.
General Rules for Laboratory Safety
- Always conduct oneself responsibly in the lab to prevent accidents.
- Carefully follow both verbal and written instructions; seek clarification if unsure.
- Do not work alone; an instructor must always be present in the lab.
- Avoid touching equipment or chemicals upon entering the lab until instructed by the teacher.
- No food, drinks, or gum are allowed in the laboratory; laboratory glassware cannot be used for food or beverages.
Conduct and Preparation
- Only perform experiments authorized by the instructor; unauthorized experiments are strictly prohibited.
- Be prepared with a thorough understanding of laboratory procedures before entering the workspace.
- Horseplay and pranks are dangerous and not allowed in the laboratory environment.
- Maintain cleanliness and organization by keeping work areas tidy and storing personal items properly.
Safety Equipment and Practices
- Know the locations and proper use of safety equipment, including eye-wash stations and fire extinguishers.
- Ensure work areas are well-ventilated; utilize fume hoods for volatile substances and avoid placing your head inside them.
- Stay alert and cautious; report any unsafe conditions to the instructor immediately.
Waste Disposal and Hygiene
- Dispose of chemical waste properly; sinks should only be used for designated solutions and water.
- Read labels and instructions carefully before using equipment; follow directions precisely.
- Keep hands clear of face and body when handling chemicals; wash hands and clean workspaces after experiments.
Monitoring and Prohibited Areas
- Monitor experiments closely at your assigned station; avoid wandering or distracting others.
- Access to science storage and preparation areas is restricted for students.
