Principles of Prevention

When the hazards are identified then the next option is to control those hazards with suitable
precautions to bring the risk to acceptable level. This is the significant part of risk assessment to
implement precaution to reduce the risk level.

The General principles of prevention encourage risks to be combatted at source, also introduce
further prevention principles such as a adapting the work to the individual can have significance
in risk reduction.

Hierarchy of Control with reference to ISO 45001 Clause 8.1.2

When determining controls, or considering changes to existing controls, consideration shall be
given to reducing the risks according to the following hierarchy:

• eliminate the hazard.
• substitute with less hazardous processes, operations, materials, or equipment.
• use engineering controls and reorganization of work.
• use administrative controls, including training.
• use adequate personal protective equipment.

In many countries, legal requirements and other requirements include the requirement that
Personal Protective Equipment (PPE) is provided at no cost to workers.

General Hierarchy of Controls

Risks should be reduced to the lowest reasonably practicable level by taking preventative
measures, in order of priority. This is what is meant by a hierarchy of control. The list below
sets out the order to follow when planning to reduce risks you have identified in your
workplace. Consider the headings in the order shown, do not simply jump to the easiest control
measure to implement.
