it happen at any time or would it be a rare event?
       * How frequently are workers exposed to the hazard?
Other factors that may affect consequence and likelihood include:
    * the conditions under which the electrical equipment is used, for example wet conditions outdoors or confined spaces
    * work practices and procedures, for example isolation, to carry out maintenance
    * the capability, skill and experience of relevant workers.

2.3              Control the risks
Once hazards have been identified and the risks assessed, appropriate control measures must be put in place.
The ways of controlling risks are ranked from the highest level of protection and reliability to the lowest. This ranking is known as the hierarchy of risk control. You must work through this hierarchy to choose the control that most effectively eliminates or minimises the risk in the circumstances, |so far as is reasonably practicable. This may involve a single control measure or a combination
of two or more different controls.

Elimination
The most effective control measure is to remove the hazard or hazardous work practice.
By designing-in or designing-out certain features, hazards may be eliminated.

Substitution
Replacing a hazardous process or material with one that is less hazardous will reduce the hazard, and hence the risk. For example, it may be reasonably practicable to use extra-low voltage electrical equipment such as a battery-operated tool rather than a tool that is plugged into mains electricity.

Isolation
Preventing workers from coming into contact with the source of an electrical hazard will reduce the relevant risks.

Engineering controls
Use engineering control measures to minimise the risk, for example installing residual current devices to reduce the risk of receiving a fatal electric shock.

Administrative controls
Administrative controls involve the use of safe work practices to control the risk, for example establishing exclusion zones, use of permits and warning signs.

Personal protective equipment (PPE)
PPE includes protective eyewear, insulated gloves, hard hats, aprons and breathing protection. Most forms of PPE are not relevant to minimising electrical risks in workplaces, except in relation
to energised electrical work.
Administrative controls and PPE do nothing to change the hazard itself. They rely on people behaving as expected and require a high level of supervision. Exclusive reliance on administrative controls and PPE must only occur where other measures are not reasonably practicable or as an interim control while the preferred control measure is being implemented.
You should check that your chosen control measure does not introduce new hazards.

2.4              Review the control measures
The controls that are put in place to protect health and safety must be reviewed regularly to make sure they work effectively.
