There are plenty of opportunities for fun in the science classroom, but you also need to know how to be safe. In this lesson, we'll talk about 19 common safety signs found in the science classroom.

Safety signs

Safety is important in the science classroom or laboratory, which is a controlled environment where you do scientific experiments. A fun experiment can turn into a dangerous situation if you do not think about safety.

Laboratory Safety Signs

This image shows common science safety signs. Let's talk about what they mean!

Safety Goggles, Lab Aprons and Gloves Signs

To protect your eyes from harmful chemicals, flames and sharp objects, you should wear safety goggles. Additionally, laboratory aprons protect your skin and clothing. Finally, you may need to wear either plastic or heat-resistant gloves to protect your hands in the lab. Do not touch any other part of your body while you have the gloves on.

Breakage, Heating, Flames and No Flames Signs

The breakage sign means that you need to handle glassware with care, because it may break. Do not touch glassware that may be broken, and always tell your teacher if you see something broken.

When you see the heating sign, use a clamp or tongs to pick up hot glassware. You should never touch hot objects without protection for your hands.

If you see the flames sign, you should tie back loose hair and clothing. Always listen to your teacher before lighting and putting out a flame.

Similarly, when you see the no flames sign, make sure there are no flames, heat sources or sparks that could happen nearby. There could be flammable materials present!

Corrosive Chemicals, Poison, and Fumes Signs

When you see the corrosive chemicals sign you must avoid getting the acid or other chemical in your eyes, on your skin or on your clothing. Corrosive means that the chemical could burn you or your clothing.

You may also see the poison symbol. This means that you should not let the poisonous chemical touch your skin, and you should never try to smell it.

There may also be fumes or vapors in your lab activity, in which case you might see the fumes sign. Make sure that there is plenty of air flow in your lab and always avoid inhaling fumes.

Sharp Object Sign

This sign tells you that sharp objects, like scissors or needles, are used in the experiment. Always keep it pointed away from yourself and others.
