Lab Safety Signs Worksheets - Free Printable

Let’s go through each sign one by one and match it with its correct name based on what the symbol shows.

1. First row, first sign: Shows an explosion with fragments flying out → This means there’s a risk of something exploding → Explosion risk

2. First row, second sign: Shows a flame → This warns that materials here can catch fire easily → Flammable materials

3. First row, third sign: Shows the classic radiation symbol (three blades around a circle) → This is for radioactive materials → Radiation

4. First row, fourth sign: Shows a flame over a circle → This means the material helps other things burn (oxidizer) → Oxidizing

5. Second row, first sign: Shows a person tripping or falling → Warns you to be careful where you step → Watch your step

6. Second row, second sign: Shows waves coming from a tower → This is non-ionizing radiation (like radio waves or microwaves) → Non ionizing radiation

7. Second row, third sign: Shows a lightning bolt hitting a person → Very dangerous — could kill you → Danger of death

8. Second row, fourth sign: Shows a wavy line with an arrow → Represents UV light (ultraviolet) → Ultraviolet radiation

9. Third row, first sign: Shows an “X” inside a triangle → Means the substance can irritate skin or eyes → Irritant

10. Third row, second sign: Shows a dead tree and fish → Harmful to nature and wildlife → Danger to the environment

11. Third row, third sign: Shows a gear or wheel turning → Warning about moving parts that can grab or crush → Rotating parts

12. Third row, fourth sign: Shows a broken glass → Danger from sharp glass pieces → Glass hazard

All signs are correctly labeled in the image. Since this is a matching/identification task, and all labels are already provided and accurate, the solution is simply confirming each label matches the symbol.

Final Answer:
All lab safety signs are correctly identified as follows:
- Explosion risk
- Flammable materials
- Radiation
- Oxidizing
- Watch your step
- Non ionizing radiation
- Danger of death
- Ultraviolet radiation
- Irritant
- Danger to the environment
- Rotating parts
- Glass hazard
