Know where the fire extinguisher is and store flammable materials properly. Be extra cautious with heat sources like Bunsen burners. Follow all laboratory safety rules for handling explosive materials.

7. Keep Lab Work in the Lab

Don’t take lab material or equipment outside or at home. In external laboratories, it could be a legal offence. Wash your lab clothes after each use to avoid contamination.

8. Stay Calm During Accidents

In spite of laboratory precautions, some things are bound to go wrong causing unexpected accidents. Always be prepared for that. You should remain calm and alert enough to use safety equipment around you. Notify your supervisor for suspected malfunction. Learn about and follow all emergency lab safety rules.

9. Work with a Partner

When possible, work with someone in the lab to help catch mistakes or assist during emergencies. It could be a lab technician or someone who knows lab safety rules well.

10. Be Responsible

Focus on your work and follow lab safety rules. Avoid risky or unnecessary experiments and always clean up after yourself. Let others know when handling hazardous materials.

Other Do's and Don’ts in Laboratory Settings

• Don’t breathe in chemical fumes directly; use a fume hood and waft odours toward you.
• Handle hot objects with care and use tongs for anything heated.
• Do not pipette with your mouth; use pipette bulbs.
• Plan your breaks wisely, turning off equipment and informing your instructor.
• Never come to the lab under the influence of drugs or alcohol.
• Clean your workspace and wash your hands after every lab session, ensuring everything is off.

Common Misconceptions Regarding Lab Safety Rules

Many times, lab safety rules are not taken seriously by the staff or students handling various materials or handling the lab. They think that lab safety rules are not for them since they’re aware of how to handle various aspects. Turns out, they’re at an increased risk of danger. Lab accidents can happen in the most unexpected circumstances. So, personal safety is a blind rule before entering or working in a lab, especially in chemical and medical labs.

Wearing Gloves Means I’m Safe

Some individuals think that simply wearing gloves is sufficient protection. However, gloves can have holes or be made from materials that are not suitable for all chemicals. You should choose the right type of glove based on the substances being handled.

Eating in the Lab is Okay if I’m Careful

A common belief is that eating in the lab is safe as long as precautions are taken. This is false; consuming food in the lab can lead to contamination and exposure to hazardous materials.

Safety Equipment is Optional

Some may think that using safety equipment, like goggles or face shields, is optional if they feel they can manage without them. In reality, these items are indispensable for protecting against potential splashes and debris.

I Can Handle Small Spills Without Proper Protocol

There's a misconception that minor spills can be managed informally. In truth, even small spills can pose significant risks, and established protocols should always be followed for cleanup.

The Lab is Not a Dangerous Place

Many new lab users underestimate the risks associated with lab work. Hazards are inherent in laboratory settings, and assuming safety can lead to complacency and accidents.

Hand Washing Instructions for Lab Safety
