Hazard warning labels
Introduction
In chemistry, hazard warning labels are like little
stickers that we put on bottles or containers to
tell us if a chemical can be dangerous. They are
pictures and words to help us use special rules
when working with those chemicals, so nobody
gets hurt.
Why are learning and reading labels important?
Learning and reading labels are important
because they tell you what substances are in a
product and how to handle them safely. This
helps prevent accidents, like mixing chemicals
that could react dangerously. You can help
prevent illness and injury by reading the warning
label for each hazardous substance you use. The
overall goal is to prevent injuries and save lives.

explode if it comes into
contact with a flame or
heat.

Oxidizing
A substance that gives
off a large amount of

with other
substances.

destroy living tissue. It
