##### Task 1: Label the items in the diagram
Here is a description of where each item might be located in the provided diagram:

1. Fire Extinguisher: Located on the wall near the top right corner.
2. Sink: On the countertop, with a faucet above it.
3. Glass Bin: A container labeled "GLASS" on the floor near the sink.
4. Acid Bottles: Likely stored in the cabinet or on the countertop (not explicitly shown but common in labs).
5. Bunsen Burner: Not visible in this diagram, but typically found on the countertop.
6. Eyewash Bottle: Near the sink, often mounted on the wall.
7. Fume Cupboard: The large cabinet on the left side of the diagram.
8. Safety Goggles: Not explicitly shown but are commonly used in labs.
9. Safety Mat: Not visible but often placed under work areas to protect the floor.
10. Gas Taps: Likely part of the Bunsen Burner setup, though not explicitly shown.
11. Electrical Sockets: Not visible but typically present on the walls or counters.
12. Sand Bucket: Not visible but sometimes used for fire safety.
13. Fire Blanket: Not visible but often kept near the Bunsen Burner or other heat sources.

##### Task 2: Which items can you see in your lab?
This depends on the specific lab environment. For example:
- Sink
- Glass Bin
- Fume Cupboard
- Eyewash Bottle
- Gas Taps (part of Bunsen Burner)
- Electrical Sockets

#### Right Page: Lab Safety Rules!

##### Task 1: Identify what is going wrong in the chaotic lab scene
From the image, several unsafe behaviors and conditions are evident:
1. Running in the lab: People are running, which can lead to accidents.
2. Eating and drinking: Individuals are consuming food and beverages, which is prohibited in labs due to contamination risks.
3. Improper handling of chemicals: Someone appears to be pouring or handling chemicals carelessly.
4. Open flames near flammable materials: Candles or open flames are being used near paper or other flammable objects.
5. Lack of supervision: No one seems to be monitoring the activities, increasing the risk of accidents.
6. Cluttered workspace: The lab is messy, with items scattered around, increasing the risk of tripping or spills.
7. No protective gear: People are not wearing safety goggles, lab coats, or gloves.
8. Overcrowding: Too many people are in the lab, leading to congestion and potential accidents.

##### Task 2: Write safety rules for each issue
1. Do not run in the lab.
2. Do not eat, drink, or chew gum in the lab.
3. Handle chemicals carefully and follow proper procedures.
4. Avoid open flames near flammable materials.
5. Always have a supervisor present when conducting experiments.
6. Keep the lab clean and organized.
7. Wear appropriate protective gear (e.g., safety goggles, lab coat, gloves).
8. Maintain a safe distance from others and avoid overcrowding.

##### Task 3: Explain why each safety rule is important
1. Do not run in the lab: Running increases the risk of slipping, falling, or knocking over equipment, which can cause injuries or chemical spills.
2. Do not eat, drink, or chew gum in the lab: Consuming food or drinks can lead to contamination of samples or ingestion of harmful substances.
3. Handle chemicals carefully: Improper handling can result in spills, exposure to hazardous materials, or chemical reactions.
4. Avoid open flames near flammable materials: This prevents fires and explosions, which can be catastrophic.
5. Always have a supervisor present: Supervisors ensure that procedures are followed correctly and can intervene in case of emergencies.
6. Keep the lab clean and organized: A tidy lab reduces the risk of accidents, such as tripping or misplacing equipment.
7. Wear appropriate protective gear: Protective gear shields against chemical splashes, burns, and other hazards.
8. Maintain a safe distance from others: Overcrowding can lead to accidental collisions or interference with experiments.

##### Challenge: Rank the safety rules by importance
1. Do not run in the lab: High risk of immediate injury or accident.
2. Avoid open flames near flammable materials: High risk of fire or explosion, which can be life-threatening.
3. Handle chemicals carefully: Chemical spills or exposures can cause severe harm.
4. Wear appropriate protective gear: Essential for preventing direct contact with hazards.
5. Do not eat, drink, or chew gum in the lab: Important to prevent contamination and ingestion of harmful substances.
6. Keep the lab clean and organized: Reduces general risks of accidents and improves efficiency.
7. Always have a supervisor present: Ensures oversight and quick response to emergencies.
8. Maintain a safe distance from others: Helps prevent accidental interference or collisions.
