Lab and Experiment Safety - Free Printable

Let's analyze the cartoon and answer each question based on the visual clues and common lab safety principles.

---

1. List 3 unsafe activities shown in the cartoon and explain why each is unsafe.

a) Bob spilling a chemical (labeled "H₂O") while holding a beaker with one hand and walking.
- Why it's unsafe: Walking while carrying chemicals without proper support increases the risk of spills, which can cause burns, contamination, or reactions. He should use both hands or a cart to transport chemicals safely.

b) Jim eating food in the lab.
- Why it's unsafe: Eating in the lab is dangerous because chemicals could contaminate food, leading to ingestion of hazardous substances. Labs are not meant for consumption of any kind.

c) Sue using a hairdryer near chemicals and electrical equipment.
- Why it's unsafe: Hairdryers are electrical devices that can create sparks or short circuits if used near flammable materials or water. Also, they are not appropriate lab tools and may cause accidents.

2. What should Bob do after his accident?

After Bob spills a chemical and gets burned (as indicated by “OUCH!”), he should:
- Immediately rinse the affected area under running water for at least 15–20 minutes.
- Report the incident to the teacher or supervisor.
- Use the safety shower (visible in the background) if the burn is severe.
- Seek medical attention if needed.
- Inform others so they can avoid the spill.

> Note: The cartoon shows Bob reacting in pain — this suggests he needs immediate first aid.

3. What should Sue do to avoid an accident?

Sue should:
- Not use a hairdryer in the lab, especially near chemicals and electrical outlets.
- Keep personal items like hairdryers out of the lab environment.
- Follow proper lab procedures and only use approved equipment.
- Wear appropriate protective gear such as goggles and lab coat.

4. What safety procedure is Tina following?

Tina is washing her hands at the sink. This is a crucial safety procedure because:
- It removes any chemicals or contaminants from her hands.
- Prevents accidental ingestion or transfer to eyes or face.
- Helps maintain hygiene and reduce exposure risks.

This is a correct and essential lab practice.

5. Compare Joe and Carl’s lab techniques. Who is doing it the correct way?

- Joe is pouring liquid into a test tube without using a funnel and appears to be doing it carelessly. He might splash or spill, and he isn’t wearing proper protection.
- Carl is carefully pouring liquid from a graduated cylinder into a beaker, using proper technique and appears to be focused. He is also wearing a lab coat.

✔ Carl is doing it the correct way. He demonstrates careful handling, appropriate attire, and safe measurement practices.

6. List 4 pieces of safety equipment that are in the lab.

From the cartoon, we can identify:

1. Safety Shower – Located near the back wall, clearly labeled.
2. Fire Extinguisher – Visible on the wall near the door.
3. First Aid Kit – Mounted on the wall.
4. Eye Wash Station – Near the sink, where Tina is washing her hands.

These are all standard safety features in a science lab.
