Safety And Apparatus Flashcards
All chemicals have a safe side and dangerous side. List the safe and dangerous sides of H2O
Safe: we drink it as water. It’s refreshing and hydrating
Dangerous: it can often cause flash floods and can drown people. Water is a scary thing
Why do we have hazard symbols?
They warn us about the dangers a certain type of chemical might have. They warn us if any danger is present and if so what danger.

If the symbol had a flame on it, what’s the hazard?
It’s flammable
What’s the symbol for “acute toxicity”
A skull and crossbones
If the symbol were an exclamation mark, what would the hazard be?
Health hazard/hazardous to ozone layer
Define oxidising
Combined chemically with oxygen or TO combine chemically with oxygen
What symbol is used for the hazard “oxidising”
A flame over a circle
If the symbol were corrosion of hand and block, what would the hazard be?
Corrosive
