Hazards Biological
A hazard is a source of energy that has the potential to cause harm, ill health or injury, or damage to property, plant
or environment. Does the job step you are about to do involve energy sources that need to be controlled? If you
tick yes for any of the hazards below, please list them on the JHA form and detail how they will be controlled.
Hierarchy of Control
When selecting your controls, work through the hierarchy of control model. Controls in this model are listed
from most effective to least effective. Aim to select the most effective control possible for hazards in your work
tasks.
1. Can you Eliminate the hazard?
(e.g. use
mechanical device to eliminate manual lifting
requirements)
2. Can you Substitute the hazard with another tool?
3. Can you apply Engineering solutions to
control the hazard?
4. Can Administrative procedures control
the hazard?
5. Can Personal Protective Equipment (PPE)
control the hazard?
(e.g. use low voltage instead of high voltage power
tool)
(e.g. guards, barriers, hydraulic tools, toolbox
lid braces)
(e.g. training, stepback, first aid equipment,
journey management plans)
(e.g. gloves, safety glasses, safety
harness, respiratory equipment)
