Q & A

Why is it important to follow safety rules in a lab?

Following safety rules in a lab is important to prevent injuries and ensure that experiments are conducted safely, minimizing risks.

What should be done before starting a lab experiment?

Before starting a lab experiment, you should read over all directions carefully to understand the materials needed and the steps involved.

Why is it necessary to work in a clean space during an experiment?

A clean workspace helps you stay organized, ensures proper observation of the experiment, and reduces the chance of contamination or accidents.

What protective gear is commonly required in a lab setting?

Common protective gear in labs includes goggles to protect the eyes, lab aprons to protect clothing, and gloves to protect the skin.

What should you do if you need to observe the odor of a substance during an experiment?

You should not inhale directly; instead, gently wave air from the container towards your nose with your hand to get an idea of the odor.

What precautions should be taken when working with open flames in the lab?

Keep all flammable materials away from the flame, know the location of a fire extinguisher, and be familiar with how to operate it in case of fire.

What steps should be followed if you get a cut during a lab experiment?

Flush the wound with running water, then take appropriate first-aid measures to clean and protect the area.

How should broken glass be cleaned up in a lab?

Use a dustpan and broom to clean up broken glass, and dispose of it in the garbage to avoid injury.

What is the proper way to flush your eyes if they come into contact with a chemical irritant?

Flush each eye gently with water, using either a shower or a small cup of clean water, keeping the eye open. If wearing contact lenses, remove them before flushing.

What should be done after completing a lab experiment?

Clean your workspace, dispose of chemicals properly as instructed, wash any reusable tools with soapy water, and wash your hands to remove any remaining materials.
