Step-by-step solution for: What Not to Do Laboratory | Math = Love
This image is a humorous yet educational cartoon titled "What-Not-To-Do Laboratory", created by the Laboratory Safety Institute (LSI) to highlight common laboratory safety violations. The goal of this illustration is to show various unsafe practices in a lab setting so that viewers can learn what not to do in a real laboratory.
Let’s go through and identify all the safety violations depicted in the image, explaining each one:
---
- Issue: Multiple people are working without proper personal protective equipment (PPE).
- Examples:
- One person is handling chemicals without gloves or goggles.
- Another is wearing sandals—never acceptable in a lab.
- A person is eating or drinking in the lab—this is strictly prohibited.
> ✔ Correct Practice: Always wear lab coat, safety goggles, gloves, and closed-toe shoes.
---
- Issue: A person is eating near chemicals and equipment.
- Risk: Contamination, accidental ingestion of toxic substances.
> ✔ Correct Practice: Never eat, drink, or chew gum in the lab.
---
- Issue:
- A person is pouring a liquid into a beaker with no protection.
- Another is smoking while handling chemicals.
- Someone is using a Bunsen burner without proper ventilation or supervision.
- Risk: Fire, inhalation of fumes, chemical exposure.
> ✔ Correct Practice: Handle chemicals carefully, use fume hoods, and never smoke in the lab.
---
- Issue:
- Flammable chemicals are stored near heat sources (like a Bunsen burner).
- Chemicals are stacked haphazardly on shelves.
- Cylinders (gas tanks) are not secured upright.
- Risk: Spills, leaks, fires, explosions.
> ✔ Correct Practice: Store chemicals properly: flammables in approved cabinets, cylinders secured, labeled clearly.
---
- Issue: Tables are cluttered with equipment, glassware, and boxes.
- Risk: Tripping hazards, spills, contamination.
> ✔ Correct Practice: Keep work areas clean and organized.
---
- Issue:
- A person is running in the lab (dangerous with chemicals and glassware).
- Another is playing with a laser device (labeled “DANGER LASER”) without eye protection.
- Someone is throwing something (possibly a chemical) into a trash can—never do this.
- Risk: Accidents, injuries, fire, or explosion.
> ✔ Correct Practice: Walk, not run; follow laser safety protocols; dispose of chemicals properly via waste containers.
---
- Issue:
- A sign says “First Aid Party Saturday” — misleading and dangerous! First aid should be available at all times, not just for parties.
- A sign says “Safety Glasses” but no one is wearing them.
- SDS (Safety Data Sheets) are present but ignored.
- Risk: Lack of preparedness in emergencies.
> ✔ Correct Practice: Follow all safety signs, keep first aid accessible, read SDS before handling chemicals.
---
- Issue: A gas cylinder is lying on its side—can roll or leak.
- Risk: Gas leak, fire, explosion.
> ✔ Correct Practice: Secure gas cylinders upright with chains or straps.
---
- Issue: A person throws a chemical container into a regular trash can, causing an explosion.
- Risk: Dangerous reactions, fire, release of toxic gases.
> ✔ Correct Practice: Dispose of chemicals in designated hazardous waste containers.
---
- Issue: Two people are standing near a "DANGER LASER" cart, possibly looking directly at it.
- Risk: Eye damage or blindness.
> ✔ Correct Practice: Use laser safety goggles, avoid direct exposure, and follow laser safety protocols.
---
- Issue: While a shower is shown, it's unclear if it's functional or accessible. Also, no visible fire extinguisher.
- Risk: Delayed response during emergencies.
> ✔ Correct Practice: Ensure emergency showers, eyewash stations, and fire extinguishers are present, accessible, and regularly checked.
---
- Issue: A person is blowing up a balloon with a chemical reaction—unsafe and uncontrolled.
- Risk: Explosion, chemical splash.
> ✔ Correct Practice: Conduct experiments only under controlled conditions and with proper training.
---
Even though this is a "what-not-to-do" cartoon, some things are correct:
- There is a first aid kit posted.
- A safety glasses sign exists.
- An exit sign is visible.
- SDS (Safety Data Sheets) are available.
- A safety shower is installed.
- A laser warning sign is present.
These are good practices, but they're being ignored by the people in the lab.

The cartoon humorously illustrates how NOT to behave in a lab. It teaches us that:
- Always wear PPE.
- Never eat, drink, or run in the lab.
- Store chemicals properly.
- Dispose of waste safely.
- Follow all safety procedures.
- Know where emergency equipment is.
- Respect hazard signs and warnings.

This cartoon serves as a powerful reminder that lab safety is everyone’s responsibility. By avoiding these mistakes, you protect yourself, your colleagues, and the integrity of your experiments.
> 🔐 Remember: A safe lab is a productive lab.
