Chemical Safety

Chemicals can be very dangerous so it is important to be aware of the correct ways to store, use and dispose of chemicals.

Chemicals at work

People who work with potentially dangerous chemicals should be fully trained before they come into contact with the substances. All dangerous chemicals should be clearly marked with warning signs and rooms that contain harmful substances should also have signs to warn people not to enter. Employees may be advised to wear protective clothing including goggles and gloves when using chemicals. Chemicals should also be disposed of in a specific way; instructions surrounding the disposal of waste should be clearly displayed throughout the workplace.
