1. Glassware Safety

- Symbol: A beaker with a flame.
- Rules:
- Never use broken glassware.
- Never heat glassware that isn’t thoroughly dried.
- Use heat-resistant gloves to pick up glassware.
- Always clean glassware thoroughly before putting it away.

Explanation: Broken glassware can cause cuts, and heating wet glassware can lead to thermal shock, causing it to shatter. Proper handling and cleaning are essential to prevent accidents.

2. Fire/Heat Safety

- Symbol: A flame.
- Rules:
- Safety goggles should always be worn when working with fire.
- Have a clean work area.
- Never reach across a flame.

Explanation: Fire hazards are common in labs. Wearing safety goggles protects your eyes from sparks or hot debris. A clean workspace reduces the risk of accidental fires, and reaching across flames can lead to burns.

3. Heating Safety

- Symbol: A hand with a burn mark.
- Rules:
- Never heat something unless instructed to do so.
- Never heat anything with a closed container.
- Always use clamps, tongs, or heat-resistant gloves.

Explanation: Heating materials without proper instruction can lead to dangerous reactions. Closed containers can explode due to pressure buildup. Using appropriate tools ensures safe handling of hot objects.

4. Chemical Safety

- Symbol: A skull and crossbones.
- Rules:
- Never smell chemicals directly.
- Never mix chemicals unless instructed so.
- Never touch or taste chemicals.

Explanation: Directly smelling chemicals can expose you to harmful fumes. Mixing chemicals without proper guidance can lead to toxic reactions. Touching or tasting chemicals is extremely dangerous and can cause poisoning.

5. Eye Protection

- Symbol: Safety goggles.
- Rules:
- Must wear safety goggles.
- When heating a test tube or bottle, always point it away from you and others.

Explanation: Safety goggles protect your eyes from chemical splashes, flying debris, and hot substances. Pointing heated containers away from yourself and others prevents injury if something spills or explodes.

6. Sharp Instruments Safety

- Symbol: A hand holding a sharp object.
- Rules:
- Handle sharp instruments with care.
- Always cut materials away from you.
- Notify your teacher if your skin is cut.

Explanation: Sharp instruments like scalpels or razor blades can cause cuts. Cutting away from yourself minimizes the risk of injury. Reporting any cuts promptly ensures proper medical attention.

7. Electrical Safety

- Symbol: An electrical plug.
- Rules:
- Do not plug more than two appliances in at any outlet.
- Never touch an electrical appliance/outlet with wet hands.
- Keep liquids away from appliances and outlets.

Explanation: Overloading outlets can cause electrical fires. Wet hands increase the risk of electric shock. Keeping liquids away from electrical equipment prevents short circuits and damage.

8. Animal Safety

- Symbol: An animal icon.
- Rules:
- Do not cause pain or injury to an animal.
- Do not perform in humane stunts/actions with an animal specimen.

Explanation: Labs may involve animals for experiments. It is crucial to treat them humanely and avoid actions that could harm them physically or psychologically.
