Step-by-step solution for: Lab Safety and Hazard Symbols KS3 Science
Let's solve the Lab Safety worksheet step by step, based on the two pages shown.
---
#### 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 behind the sink or near the door.
- Sink
→ Clearly visible in the center of the countertop.
- Glass Bin
→ The bin labeled “GLASS” is on the floor next to the counter.
- Electrical Sockets
→ Look for outlets on the wall — probably near the sink or on the back wall.
- Acid Bottles
→ Likely stored in a cabinet or on a shelf. They may be labeled with hazard symbols.
- Gas Taps
→ These are valves connected to gas lines — often near Bunsen burners. Might be under the bench or near the wall.
- Safety Goggles
→ A pair of goggles placed on the counter near the sink.
- Bunsen Burner
→ A small burner device on the countertop (usually near the sink or gas taps).
- Eyewash Bottle
→ A bottle with a spout for flushing eyes — often located near the sink.
- Safety Mat
→ A mat on the floor where students stand during experiments — possibly under the workbench.
- Fume Cupboard
→ A large enclosed cabinet with a vented hood — located at the back of the lab (the large box structure with glass doors).
> ✔ Tip: Use a pencil and ruler to draw lines from labels to items, then use a pen to write the labels.
---
#### Task 3: Which of these things can you see in your lab?
This is a reflective question. Example answer:
> I can see the sink, fire extinguisher, safety goggles, fume cupboard, and eyewash station in my lab. I also have acid bottles stored safely in cabinets and gas taps connected to Bunsen burners.

This page shows a chaotic cartoon lab scene with many unsafe behaviors.
#### Task 1: Write down a list of all the things going wrong in this lab
Here’s what’s happening (and why it’s dangerous):
1. Someone is drinking a chemical → Never consume anything in the lab.
2. A student is eating food → Food and drinks are not allowed in labs.
3. A person is throwing something across the room → Could cause breakage or injury.
4. A student is running in the lab → Increases risk of tripping, spilling chemicals.
5. A student has no safety goggles → Eye protection is essential.
6. A student is using a Bunsen burner without supervision → Risk of fire or burns.
7. A student is holding a lit test tube over another person → Could ignite flammable substances.
8. A student is pouring liquid into a container that’s too full → Risk of spillage.
9. A student is leaning over a boiling flask → Risk of splash injuries.
10. Students are sitting on stools while working → Not safe; should be standing or seated properly.
11. Backpacks are left on the floor → Obstructs walkways, causes trips.
12. Chemicals are being handled carelessly → Risk of mixing incompatible substances.
13. No one is wearing lab coats → Skin exposure to chemicals.
14. One student is putting their hand in a flame → Severe burn risk.
15. A student is touching electrical equipment with wet hands → Electric shock hazard.
---
#### Task 2: For each, write a safety rule
| What's Wrong | Safety Rule |
|--------------|-------------|
| Drinking chemicals | Never taste or drink any substance in the lab. |
| Eating food | No food or drink allowed in the lab. |
| Throwing objects | Do not throw anything in the lab. |
| Running | Walk, do not run in the lab. |
| No goggles | Always wear safety goggles when handling chemicals or doing experiments. |
| Unsupervised Bunsen burner | Never leave a Bunsen burner unattended. |
| Holding lit test tube near others | Keep flames away from people and flammable materials. |
| Overfilling containers | Never fill containers more than halfway. |
| Leaning over hot liquids | Stand back from boiling liquids to avoid splashes. |
| Sitting on stools | Stay seated only if safe and stable; avoid distractions. |
| Backpacks on floor | Keep walkways clear of obstacles. |
| Careless chemical handling | Handle chemicals with care; follow procedures. |
| No lab coat | Wear a lab coat to protect clothing and skin. |
| Hand in flame | Never place hands near open flames. |
| Wet hands near electricity | Keep hands dry when using electrical equipment. |
---
#### Task 3: Explain why each rule is important
Let’s take a few examples:
1. Never taste or drink chemicals
→ Chemicals can be toxic, corrosive, or poisonous even in small amounts. This rule prevents accidental poisoning.
2. No food or drink
→ Contamination risk: food could absorb harmful vapors or get contaminated by chemicals.
3. Always wear safety goggles
→ Protects eyes from chemical splashes, flying particles, or UV light from reactions.
4. Do not run
→ Running increases fall risk, which can lead to spills, broken glass, or fires.
5. Keep walkways clear
→ Ensures quick evacuation during emergencies and prevents accidents.
6. Wear lab coats
→ Prevents chemicals from contacting skin or clothing.
7. Never leave a Bunsen burner unattended
→ Unattended flames can ignite flammable materials or cause fires.
8. Use proper disposal methods
→ Prevents hazardous reactions between incompatible chemicals.
---
Here’s a possible ranking (from most to least critical):
1. Always wear safety goggles
→ Eyes are extremely sensitive; damage is often permanent.
2. Never taste or drink chemicals
→ Can result in immediate poisoning or death.
3. Keep walkways clear
→ Essential for emergency evacuation.
4. No running
→ Prevents falls and spills.
5. Never leave a Bunsen burner unattended
→ Fire risk is high.
6. Wear a lab coat
→ Prevents skin exposure.
7. No food or drink
→ Prevents contamination and ingestion.
8. Handle chemicals carefully
→ Prevents dangerous reactions.
9. Keep hands dry around electricity
→ Prevents electric shocks.
> ✔ Explanation: The top rules prevent life-threatening situations (eye injury, poisoning, fire), so they are ranked highest. Others are still important but less immediately dangerous.

This worksheet teaches students:
- How to identify key safety equipment.
- Recognize unsafe behaviors.
- Understand why lab rules exist.
- Prioritize safety based on risk level.
By completing this activity, students learn that lab safety isn’t just about rules—it’s about protecting lives.
