Hazard
A hazard is defined as the potential of a substance to cause harm. Hazards are a property of a substance and can not be reduced (see 'Hazard Warning Signs' for the common hazards).
Risk
Risk is how likely that a substance will be harmful under the conditions it is used. Risks can be reduced by using smaller amounts of chemicals and taking precautions such as containment in fume hoods.
Risk Assessment
An effective risk assessment will take into account the hazards involved, who will be at risk, the steps needed to minimise risks and the safe means of disposal of the substances used.
