#### Task 2: Find and label the following items on the diagram
You are given a simple line drawing of a science lab. You need to locate and label these items:
- Fire Blanket
→ Usually found near the exit or above a workbench. In this image, it might be mounted on the wall near the door (look for a folded cloth-like object).
- Sand Bucket
→ A bucket labeled "SAND" is already visible on the right side of the counter.
- Fire Extinguisher
→ Look for a red cylinder with a hose — typically mounted on the wall. It’s likely near the door or beside the fume cupboard.
- Sink
→ Clearly visible in the center of the countertop with a faucet.
- Glass Bin
→ A trash can labeled “GLASS” is shown under the counter on the right.
- Electrical Sockets
→ Look for outlets on the wall near the bench or behind the sink.
- Acid Bottles
→ These are usually stored in a cabinet or on a shelf. They may look like bottles with labels (possibly in a rack). The acid bottle is often kept in a fume cupboard.
- Gas Taps
→ Located near the Bunsen burner — small knobs or valves connected to gas lines.
- Safety Goggles
→ Might be placed on the counter or hanging nearby. In this image, they are sitting on the bench.
- Bunsen Burner
→ A device used for heating — has a base and a nozzle. Found on the bench.
- Eyewash Bottle
→ A large eye-wash station with a faucet-like structure. This is typically located near the sink or at the edge of the bench.
- Safety Mat
→ A mat placed on the floor near the Bunsen burner or chemical area. Could be under the bench or in front of the sink.
- Fume Cupboard
→ A large enclosed cabinet with a glass front and a fan — used to contain fumes. Shown as a box with a glass panel and a sign.
> ✔ Tip: Use a pencil and ruler to draw lines from the item names to their locations, then write the labels clearly.

#### Task 3: Look around you. Which of these things can you see in your lab?
This is a reflective question. You should list which of the above items are actually present in your school lab.
Example answer:
> I can see the sink, Bunsen burner, safety goggles, fire extinguisher, glass bin, and fume cupboard in my lab.

The cartoon shows a chaotic lab where no safety rules are followed. Let's analyze what’s wrong.

#### Task 1: List all the things going wrong in this lab
Here’s a detailed list of unsafe behaviors and conditions:
1. No safety goggles – Several students are not wearing protective eyewear.
2. Eating and drinking in the lab – One student is eating a sandwich, another is drinking from a cup.
3. Running in the lab – Students are running, which could lead to spills or collisions.
4. Poor clothing – One student has long hair, loose clothes, or no proper lab coat.
5. Horseplay / Fighting – Students are pushing each other, one is throwing something.
6. Improper handling of chemicals – A student is pouring liquid into a test tube without care; others are holding flasks dangerously.
7. Unattended experiments – A Bunsen burner is lit but unattended.
8. Spills on the floor – Liquid is spilled, creating a slip hazard.
9. Flammable materials near open flames – Paper or other combustibles are near a flame.
10. Using electrical equipment improperly – Someone is plugging in a device near water or without supervision.
11. Not using a fume cupboard – A student is working with chemicals that should be in a fume hood.
12. Students standing on stools or benches – One student is perched on a stool, risking falling.
13. Lack of supervision – No teacher or adult is monitoring the lab.
14. No first aid or emergency equipment visible – Fire extinguisher or eyewash station not in view.

#### Task 2: For each issue, write a safety rule
| Problem | Safety Rule |
|--------|-------------|
| No goggles | Always wear safety goggles when working with chemicals or open flames. |
| Eating/drinking | Never eat or drink in the lab. |
| Running | No running in the lab to prevent accidents. |
| Loose clothing/hair | Tie back long hair and wear appropriate lab attire. |
| Horseplay | No horseplay or rough behavior in the lab. |
| Improper chemical handling | Handle chemicals carefully and use proper tools. |
| Unattended burners | Never leave a Bunsen burner unattended. |
| Spills on floor | Clean up spills immediately to avoid slips. |
| Flammable near flame | Keep flammable materials away from open flames. |
| Misuse of electricity | Avoid using electrical devices near water. |
| Not using fume cupboard | Use the fume cupboard when working with hazardous vapors. |
| Standing on furniture | Do not climb or stand on stools/benches. |
| Lack of supervision | Always have an adult supervisor present during experiments. |
| Missing safety gear | Know where safety equipment (fire extinguisher, eyewash) is located. |

#### Task 3: Explain why each rule is important
Let’s pick a few key ones:
1. Always wear safety goggles
→ Protects eyes from chemical splashes, flying particles, or broken glass. Eyes are sensitive and hard to replace!
2. Never eat or drink in the lab
→ Chemicals can contaminate food or drinks, leading to poisoning or illness.
3. No running
→ Prevents tripping over wires, knocking over chemicals, or causing fires.
4. Don’t leave Bunsen burners unattended
→ Flames can ignite flammable substances or cause burns if left alone.
5. Use fume cupboard for toxic chemicals
→ Ventilation prevents inhalation of harmful fumes that can cause dizziness, sickness, or long-term damage.
6. Keep flammable materials away from flames
→ Prevents fires or explosions. Even paper can catch fire quickly.
---
#### Challenge: Rank your safety rules in order of importance
Top 5 Most Important Rules (in order):
1. Always wear safety goggles
→ Eyesight is irreplaceable. Chemicals or glass shards can cause permanent damage instantly.
2. Never eat or drink in the lab
→ Poisoning can happen even with small amounts. This is a major health risk.
3. Do not leave Bunsen burners unattended
→ Open flames are a primary fire hazard. Fires spread fast in labs.
4. Use fume cupboard for hazardous chemicals
→ Inhalation of toxic gases can be fatal or cause chronic illness.
5. No running or horseplay
→ Physical chaos increases risk of spills, falls, and injuries.
> 🟩 Why this ranking?
> Eye protection and avoiding ingestion are top because they directly affect personal health and safety. Fire prevention is critical due to rapid escalation. Proper ventilation protects everyone in the room. Controlling movement prevents immediate physical harm.

This worksheet teaches:
- How to identify essential lab equipment.
- Recognizing dangerous behaviors.
- Understanding why safety rules exist.
- Prioritizing safety measures.
By completing this, students learn how to stay safe in a science lab, which is crucial for real-world lab experiences.
