Study Notes

Purpose of the Science Laboratory

Prioritize safety in science classrooms for students, teachers, and parents.
Hazards include the use of hazardous chemicals in hands-on laboratory activities.
Familiarity with the locations of safety equipment such as first aid kits, eyewash stations, safety showers, fire extinguishers, and fire blankets is crucial.

Safety Rules Overview

Signing a student safety contract is mandatory for participation in laboratory activities.
Maintain awareness of surroundings and report unsafe conditions to the instructor immediately.

Clothing and Personal Safety

Proper attire is essential; secure long hair, avoid dangling jewelry, and ensure clothing is fitted.
Closed-toe shoes are required; sandals are prohibited. Lab aprons must be worn during experiments.

Chemical Safety and Handling

Wear laboratory goggles whenever handling chemicals, heat, or glassware—no exceptions.
Dispose of chemical waste correctly; do not mix chemicals in sink drains.
Use the fume hood for working with volatile substances; do not place your head in the fume hood.

General Laboratory Conduct

Responsible behavior and adherence to instructions are essential; never work alone in the lab.
Do not consume food or beverages, touch equipment, or engage in unauthorized experiments.
Keep hands away from face while using chemicals and wash hands thoroughly after experiments.

Accidents and Emergencies

Report all accidents or injuries, no matter how minor, to the instructor immediately.
Know emergency procedures: yell "Code one" for immediate help and use eyewash stations or safety showers as needed.
In case of broken mercury thermometers, notify the instructor and follow proper clean-up procedures.

Lab Procedures

Read all labels and instructions carefully before using equipment and chemicals.
Ensure all work surfaces and equipment are cleaned and returned to storage in working order after use.
Experiments must be monitored closely, staying at assigned workstations to avoid distractions.
