Science Lab Safety

Working in the science lab can be EXCITING!

However, the lab can be dangerous if proper safety rules are not followed at all times.

Science Lab This Way!

In order to prepare for a safe year in the science lab, we are going to review a few

basic safety rules….

Preparation is KEY!

Safety Rules To Follow

A teacher should always be present when entering the lab.

Leave all of your belongings outside the lab area (or in a designated area).


No eating, drinking, or chewing gum in the lab.
