Activity: Match the symbols to different situations

1. A liquid fuel used to start off a barbecue
2. A weed killer that if ingested could kill and can make fires burn faster
3. A solid that ‘melts away at’ the hair and fats that block drains
4. Fireworks
5. A solid added to washing machines (to stop dirt forming) can cause itchy skin
6. Could negatively impact fish in a lake
7. A cleaner not strong enough to kill but can cause

Bad effects on health for example cancer and asthma

Scientists and students need to take safety precautions in the lab as they are using chemicals and fire.

Hazard symbols are used to communicate quickly and cross language barriers. Popular symbols above ^^^

Walk in the lab, follow instructions, no eating and drinking, correct uniform, no sitting during a practical.

Risk assessments are looking at what could go wrong with an activity and thinking of ways to prevent it from happening.
