Step-by-step solution for: Lab Safety Worksheet Worksheet
Let's go through each panel and answer the questions based on lab safety principles. The goal is to identify unsafe behaviors and explain how they should be corrected.
---
1. List 2 unsafe activities in this picture and explain how they should be changed to make them safe.
a.
- Unsafe Activity: *Loo is holding a test tube with her bare hands while heating it over a Bunsen burner.*
- Correction: She should use a test tube holder when heating liquids to avoid burns and prevent breaking the glass. Always heat the liquid slowly and never point the open end toward anyone.
b.
- Unsafe Activity: *Mac is using a lit Bunsen burner without wearing safety goggles.*
- Correction: He must wear safety goggles at all times during lab work to protect his eyes from splashes, sparks, or flying debris.

2. How should Rick correct his technique?
- Problem: Rick is drinking a chemical solution, which is extremely dangerous.
- Correction: Never drink chemicals. He should dispose of any unused chemicals properly and only consume food or drinks outside the lab area. All chemicals are assumed to be toxic unless labeled otherwise.
3. Are these students behaving appropriately? If not, what should they be doing differently?
- No, they are not behaving appropriately.
- Problems:
- Rick is drinking a chemical (unsafe).
- Sarah is looking into a microscope while holding a flask — possibly distracted.
- Andrew is smelling a chemical directly from the container (bad practice).
- Correct Behavior:
- Never drink anything in the lab.
- Smell chemicals by wafting (gently fanning the air toward your nose), not sniffing directly.
- Stay focused on one task at a time; avoid multitasking that could lead to accidents.

4. Compare Evelyn’s technique with Kwan’s technique.
- Evelyn: She is using proper technique — she has her eyes focused on the microscope, uses both hands to adjust the focus, and appears calm and careful.
- Kwan: He is leaning too close to the microscope, possibly putting his face near the lens or adjusting it improperly. Also, he may be handling the specimen slide carelessly.
5. Whose technique is the correct one? Why?
- Evelyn’s technique is correct.
- Why? She maintains proper posture, avoids touching the lenses with her fingers, and follows safe microscope usage rules. Kwan risks contaminating the lens or damaging the equipment by leaning too close.

6. List two things that should NOT be in the lab.
a. Food and drinks – Eating or drinking in the lab can lead to accidental ingestion of hazardous chemicals.
b. Loose clothing or jewelry – These can catch fire or get caught in equipment. (Note: In this image, one student has long hair and loose clothes.)
7. What unsafe activity is shown in this picture?
- Students are running and playing in the lab, which is dangerous because spills or broken glass can occur easily.
- One student is running with a beaker, increasing the risk of dropping it and causing a chemical spill or injury.
8. What will happen to the students who are doing the unsafe activity?
- They could spill chemicals, break glassware, or cause injuries to themselves or others. Running increases the chance of tripping and falling, especially near sharp objects or hot surfaces.
---
9. Describe Jarvis’ error.
- Jarvis is cleaning up spilled chemicals with a paper towel, but he is not wearing gloves or safety goggles.
- This is dangerous because he might absorb the chemical through his skin or inhale fumes.
- Correct procedure: Use proper PPE (gloves, goggles) and appropriate spill kits for cleanup. Some chemicals require neutralization before cleaning.
10. Who in this scenario is performing a correct procedure? What is the correct procedure?
- Penny is performing the correct procedure.
- She is wearing safety goggles and gloves, and she is using a broom and dustpan to clean up the spill safely.
- Correct procedure: Always wear PPE, use appropriate tools (like a spill kit), and report spills immediately to an instructor.
11. What is Penny doing wrong?
- Wait — Penny is actually doing everything correctly!
- However, if we interpret the question as asking about Jarvis, then:
- Jarvis is doing wrong — he is not wearing PPE and is using a paper towel instead of a spill kit.
- But since the question says "What is Penny doing wrong?", and she looks correct, perhaps there's a misunderstanding.
- Alternative interpretation: Maybe Penny is not wearing a lab coat, or she's not disposing of the waste properly. But in most versions of this worksheet, Penny is the one doing it right.
> ✔ Conclusion: There’s no significant error by Penny. She is following proper lab safety procedures.

12. What is wrong with Ernie’s behavior?
- Ernie is shouting and gesturing wildly while holding a beaker.
- This shows poor lab etiquette and could cause someone to drop their materials or panic.
- Also, he may be disturbing others or creating a distraction that leads to accidents.
- Correct behavior: Stay calm, speak quietly, and handle equipment carefully.
13. Why is Lydia’s behavior appropriate? Why is it important in a laboratory setting?
- Lydia is wearing a lab coat and safety goggles, and she is focusing on her experiment.
- Her behavior is appropriate because:
- Lab coats protect clothing and skin from spills.
- Goggles protect eyes from chemical splashes.
- Focused attention prevents mistakes.
- Importance: In a lab, safety gear protects against exposure to hazardous substances, and attention helps prevent accidents like fires, explosions, or contamination.
---
- Wear PPE: goggles, lab coat, gloves.
- Never eat or drink in the lab.
- Do not run or horseplay.
- Handle chemicals carefully — never taste or smell directly.
- Use proper tools for cleanup.
- Follow instructions and stay focused.
