Q & A

Why is wearing a lab coat mandatory in the laboratory?

A lab coat protects your skin and clothing from hazardous chemicals, preventing direct contact that could be fatal or cause serious injury.

Why is eating or drinking prohibited in the laboratory?

Eating or drinking can lead to chemical contamination, which may cause poisoning or serious health risks.

What should you do with practicum tools after use?

Clean all practicum tools properly and dispose of waste in the designated areas for solid and liquid waste to maintain safety and hygiene.

What protective equipment should be worn during laboratory activities?

Wear a lab coat, mask, gloves, and protective glasses to minimize exposure to hazardous chemicals.

How should you smell chemicals safely in the laboratory?

Do not smell chemicals directly; instead, wave your hand over the mouth of the container to direct the fumes towards your nose safely.

Why should the mouth of a test tube be pointed away from your face when heating?

Pointing the test tube away prevents hot chemicals or fumes from causing burns or injuries if they erupt during heating.

What are some common laboratory safety symbols and their meanings?

Common symbols include: easily explosive, easily oxidized, flammable, highly flammable, toxic/very toxic, irritant, corrosive, and dangerous for the environment. These symbols indicate specific hazards to handle chemicals safely.

What is the first step to take if someone swallows chemicals in the laboratory?

Induce vomiting if instructed, rinse the mouth with water, and seek immediate medical attention.

How should chemical burns be treated in the laboratory?

For mild burns, apply burn ointment; for severe burns, compress with ice water and seek medical help immediately. Toothpaste should never be used.

What should you do if chemicals splash into your eyes?

Do not rub your eyes. Rinse immediately with clean water and seek medical attention if irritation persists, as chemical exposure can cause blindness.

How should exposure to strong acids or bases on the skin be handled?

Rinse the affected area with running water to dilute the chemical, and if possible, neutralize with a weak base or apply appropriate ointment. Seek medical attention if necessary.
