SAFETY MANAGEMENT SYSTEM PROCEDURE
1 PURPOSE
The purpose of this procedure is to provide guidance and instruction to personnel that will be involved with
the following:







Confine Space
Vessel Entry
Any job that is out of the ordinary
Any change of work method
Any change of procedures & works instruction
Any client or regulatory mandatory requirement.
Any “High Risk Work” as defined in the National Standard for Construction Work
This procedure shall apply to Brierty employees and contractors working at any of their locations.
2 RESPONSIBILITIES
The responsibility of issuing and reviewing the Job Hazard Analysis rests with the Brierty Area Supervisor or
their designated nominee.
It is the responsibility of the site Supervisor to ensure that the above safe systems of work as well as any site
requirements for hazard recognition is complied with and undertaken before the task is started.
It is the responsibility of the workers or their Safety Representative to be involved in the development of
JHAs.
3 PROCEDURE DETAILS
3.1
WHEN TO CONDUCT A JHA
It is the responsibility of the Supervisor directly in charge of the job to ensure a JHA is completed when
required by the system.
The workers (Including subcontractors) or their Safety Representative must be involved in the development
of the site specific JHAs.
All jobs are subject to a JHA, however due to the practical constraints of the time and effort required, a job to
be analysed shall be identified and given priority on the following basis:







3.2
When frequency and severity of incidents require that analysis to be conducted.
When the consequences of an incident are potentially severe.
When a new job is established.
When a new Safe Work Instruction or Procedure is created.
When an existing Safe Work Instruction or Procedure is modified.
As per Clients request or Works Contract Guidelines
Any client or regulatory mandatory requirement. Conducting any “High Risk Work” as defined in the
National Standard for Construction Work
DESCRIPTION OF THE JHA TECHNIQUE
A JHA is prepared to ensure that each basic step of the job is examined to identify potential hazards and to
determine the safe method to undertake the job.
The basic stages in conducting a JHA are:

3.3
Selecting the job to be analysed.
Breaking the job down into a sequence of steps.
Identifying potential hazards.
Determining preventive methods to overcome these hazards.
Documenting the results.
Approval and sign-off and implementation
BREAKING THE JOB INTO BASIC STEPS
Having identified the job to be analysed, it should then be broken down into its component steps. Most jobs
can be described in less than ten steps.
The steps are to be recorded in the correct sequence otherwise the analysis may be invalid, due to missing
potential hazards or by introducing hazards which don’t exist.
A JHA work sheet is provided to assist with recording the steps.
Record each step in sequence, noting WHAT is to be done, not HOW by observing the usual worker doing
the job under normal conditions where possible. This may indicate that you can do the job.
Commence the recording of each step with a verb, e.g. lift, turn, open, close, etc.
Record the steps in the left-hand column of the work sheet and when complete validate the sequence of
steps by checking the steps with other workers who are familiar with the job.
3.4
IDENTIFYING THE POTENTIAL HAZARDS
The potential hazards can now be identified for each step of the job and entered in the centre column of the
work sheet. For each step, ask the following questions and any others you can think of, and if the answer is
YES or PROBABLY or POSSIBLY a hazard or potential hazard has been identified and must be recorded.

CAN any part of the body get caught in or between an object?
DO tools, machines or equipment used for the job present any hazards?
CAN objects / machinery contact the worker?
CAN the worker slip, trip or fall?
CAN the worker suffer strain from lifting, pushing or pulling?
IS the worker exposed to extreme heat or cold?
IS excessive noise or vibration a problem?
IS there a lighting problem?
CAN weather conditions affect the worker?
IS harmful radiation a possibility?
ARE flammable or explosive substances present?
CAN contact be made with hot, toxic, acidic or caustic substances?
ARE there dusts, fumes, mists or vapours in the air?
If work is carried out can Energy be released?
Is the atmosphere healthy or can it become dangerous?
ARE there particular skills or is special training required?
RECORDING THE RISK
The risk recording is to be documented as per the Risk Matrix. The process includes the following factors;
injury and disease, environmental impact, social or cultural heritage, community, government, media or
reputation, legal, operational impact and cost. The Likelihood should be determined first, followed by the
Consequence, where these meet on the matrix will be the Risk Rating, as shown on the next page. (E.g.
Possible + Minor = M18 or Be Alert)

Brierty’s preference is to use the risk matrix shown below (where Client approval can be obtained) as
it is more intuitive and easier to understand for personnel new to the industry.

DETERMINING THE PREVENTIVE MEASURES OR CONTROLS
The preventive measures will now have to be determined to eliminate or control the identified hazards; they
should be listed in order of preference by adopting the hierarchy of control, as illustrated below.
The HIERARCHY OF CONTROLS should be applied
in the following order :ELIMINATE : The complete elimination of the hazard.
REDESIGN : Redesign the equipment or work processes.
SEPARATE : Isolating the hazard by guarding or
enclosing it.
A number of
these options
may be
considered and
applied
individually, or in
combination.
ADMINISTRATE : Providing control such as training,
procedures etc.
of
nce tions
p
fere
Pre ent O
atm
Tre
SUBSTITUTE : Replacing the material or process with a
less hazardous one.
PERSONAL PROTECTIVE EQUIPMENT : Use properly
fitted PPE where other controls are not practical; impact
minimisation equipment such as spill clean up material or
dust suppression measures.
When identifying and selecting controls and preventative measures, it is preferred to place hard controls
such as Eliminate, Substitute, Redesign and Separate, as these are physical barriers for improvement. Soft
controls such as Administration and PPE are the last resort.

Follow-up
Once the JHA is completed and all identified hazards have been considered and controls determined, the
designated nominee who conducted the JHA shall forward it to the Supervisor for review and approval. The
Supervisor can then determine whether the JHA has captured the appropriate information or not. If the
Supervisor is satisfied the JHA meets the criteria, they are to sign off the JHA in the appropriate section.
The Supervisor shall be responsible for ensuring the implementation is on a consultative basis with
employees, and where appropriate, with the site OH&S Representative or Safety Department.


The Supervisor can ensure that the work method is being under taken as per the JHA by inspecting
the work areas and referring to the JHA for compliance; this will assist with the Safe Acts
Observation Process.
3.6.12 Compact Cards or Procedures
Compact Cards are an abbreviated version of Brierty Limited’s Safe Work Procedures that are available
through the Brierty intranet, located on B-Online.
The intention of these Compact Cards is to make available a quick and easy reference to assist all personnel
capturing the ‘Key Points’ of the Safe Work Procedures.
It is highly recommended that the full procedures are read by Management and any personnel performing
the task covered by the Compact Card if there are any discrepancies.
Compact Cards shall be utilised when compiling JHA’s as the relevant compact card can then be attached to
the JHA to assist personnel in complying with Brierty Limited’s Procedures.
