Study Notes

Safety Procedures in the Science Classroom

Science classes involve hands-on activities with hazardous materials; safety is the highest priority.
A student safety contract must be signed by students and guardians to participate in laboratory activities.

Recognizing Safety Equipment

Be familiar with the locations and usage of safety equipment: first aid kit, eye wash station, safety shower, fire extinguisher, fire blanket, and alarms.
Know the emergency exits and fire drill procedures before beginning lab work.

Clothing and Personal Protection

Always wear laboratory goggles during activities involving chemicals, heat, or glassware.
Secure long hair, avoid loose clothing and dangling jewelry; closed-toe shoes are mandatory.
Lab aprons must be worn at all times for protection against spills and splashes.

Laboratory Conduct

Responsibility and attentiveness are crucial; never work alone without an instructor present.
Avoid eating, drinking, or using laboratory glassware for food or beverages.
Horseplay, pranks, and distractions are strictly prohibited in the lab environment.

Chemical Handling Guidelines

Chemicals must be accessed and handled with care; never return unused chemicals to their containers.
Use proper techniques for handling acids; always add acid to water, not the reverse.
Wafting vapors is the appropriate method to smell chemicals safely.

Working with Glassware and Equipment

Handle glassware with care; use a brush and dustpan for broken glass and place it in designated containers.
Always lubricate glass tubing to avoid breakage when inserting into stoppers.
Use heat-resistant materials to handle hot apparatus; never place hot glass directly on a surface.

Emergency Procedures

Report all accidents, no matter how small, to the instructor immediately.
If exposed to chemicals, flush the affected area with running water for at least 20 minutes and seek assistance.
In cases of fire, ensure containers are closed and equipment is turned off following safety protocols.

Student Agreement

Students acknowledge understanding and committing to safety rules; violation may lead to disciplinary actions, including removal from the lab.
The teacher will provide instructions on all safety procedures and handling techniques before laboratory activities.### Electrical Safety in the Laboratory
Always grasp the plug, not the electrical cord, when removing it from a socket to avoid damage and ensure safety.
Ensure hands are completely dry before touching any electrical switch, plug, or outlet to prevent electrical shock.

Glassware Safety

Inspect glassware before each use for any damage such as chips or cracks; damaged glassware should not be used.
Dirty glassware must not be utilized as it can lead to contamination and invalid results in experiments.

Reporting Equipment Issues

Report any damaged electrical equipment immediately to ensure a safe laboratory environment.

Parental Awareness

Parent or guardian consent is required for students participating in laboratory activities.
Parents/guardians must be aware of any allergies the student may have that could affect laboratory work.

Reproduction Rights

Permission is granted to science teachers who are customers of Flinn Scientific, Inc., for reproduction of material for educational purposes, while restrictions apply to other types of reproduction without written consent.
