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.
