Master Builders Western Australia — May-June 2017

Using the following Risk Matrix determine the level of risk associated with each identified hazard

and record that information in the IR (Inherent Risk) column on the JSA/SWMS form.

5. Develop and recommend hazard
   control strategies
   Use Codes of Practice, Australian Standards,
   industry guidelines and government
   department information for practical advice
   for achieving acceptable standards when
   determining appropriate control measures.

Hazard control process involves identifying the
range of options available for a specific hazard,
or hazardous situation, evaluating the potential
effectiveness of these options and preparing a
JSA to clearly identify the hazard, the related
control measures to be implement and the
person responsible for ensuring this happens.

The hierarchy of hazard control (where
elimination is the most effective control and
personal protective equipment, the least
effective) should be used to help determine
the most effective controls. A combination of
controls can be used.

ALMOST CERTAIN HIGH (3) HIGH (3) EXTREME (4) EXTREME (4) EXTREME (4)

LIKELY MODERATE (2) HIGH (3) HIGH (3) EXTREME (4) EXTREME (4)

UNLIKELY LOW (1) LOW (1) MODERATE (2) HIGH (3) EXTREME (4)

RARE LOW (1) LOW (1) MODERATE (2) HIGH (3) HIGH (3)

6. Assess the risks after controls are
   in place
   Using the Risk Matrix, determine the level of
   risk associated with each identified hazard
   after the controls have been determined and
   record that information in the RR (Residual
   Risk) column on the JSA/SWMS form.


7. Document and authorise
   Record the details on the JSA/SWMS sheet
   and submit to site supervisors for authorisation
   prior to carrying out the job.
   8. Store, review and update
   After the JSA/SWMS is complete, it must be
   reviewed to determine:
   
   
   • Did the identified controls reduce the risk?
   
   
   • Were any hazards missed?
   
   
   • Were the controls effective?
   
   
   • Can the risk be reduced further?
   
   
   
   

Modify the JSA/SWMS accordingly. Any

updates or modifications must be approved

and relevant personnel informed.

TYPE OF CONTROL DEFINITION EXAMPLE

ELIMINATION The hazard is removed altogether; task or process may be eliminated • Removal of asbestos

SUBSTITUTION

Replaces the hazard or hazardous

process with one that presents

a lower risk

• Use non fibrous insulation instead of
  fibreglass insulation,


• Use lead free paint instead of lead
  based paint,


• Use steel fencing instead of
  asbestos fencing.

ENGINEERING CONTROLS

Structural change to the working

environment, equipment/ or work

process that forms a protective barrier

between the hazard and the employee

• Edge protection,


• Reversing beeper on moving plant


• Machine guards,


• Cranes for heavy lifting.

ADMINISTRATIVE CONTROLS

Reduces the exposure to the hazard

through procedural instructions, training

and signs, permits and procedures etc.

• Policy,


• Procedure,


• Safe work practice,


• Job safety Assessment,

PERSONAL PROTECTIVE

EQUIPMENT

Worn by exposed employees to

provide a last line defence should

other controls prove ineffective, or it is

used in conjunction with other control

measures. The selection offered by

PPE relies on correct selection, fitting,

maintenance, and use

• Hard hat/safety helmet,


• Safety glasses/face mask


• Ear plugs/muffs,


• Dust mask/Respirator,


• Gloves


• Long sleeve shirt

1. Elimination


2. Substitution

4. Administrative


5. Personal Protective Equipment

Most effective

Least effective

JSAs/SWMSs must be easily accessible to

all employees, subcontractors and persons

involved in, or affected by, the task.
