Hazard identification, risk assessment and risk control identification are central to the
process for control of MHF. Several additional MIHAPs may need
to be consulted to address related issues that are outside the scope of this MIHAP. In
particular, both MIHAP No. 4 and MIHAP No. 5 should be consulted at an early stage.
The findings of the hazard identification, risk assessment and risk control process are
a key input to the Operator’s Safety Improvement Program (SIP), which is described in
MIHAP No. 5 – Safety Reporting. Other documentation relating to the hazard
identification, risk assessment and risk control process that must be submitted to the
MHU as part of the Safety Report is also outlined in MIHAP No. 5, together with the
relevant assessment criteria.
Guidance on Safety Management Systems (SMS) for MHFs (which are important for
ensuring implementation and ongoing management of the identified control
measures) is provided in MIHAP No. 4.

1.1 Background

The National Occupational Health and Safety Commission (NOHSC) declared a
National Standard for the Control of Major Hazard Facilities (National Standard) in
1996, the objective of which is ‘to prevent major accidents and near misses, and to
minimise the effects of any major accidents and near misses’ (National Standard
Section 2.1) at major hazard facilities (MHFs).

Meeting the objective of accident prevention starts with the facility Operator
identifying and assessing hazards and implementing control measures to reduce the
likelihood and effects of a major accident (National Standard Section 2.1 (a)). To
identify, assess and control major accident hazards, the Operator must consider the
protection of people (both on- and off-site), property and the environment.
In NSW, the objectives and relevant requirements of the National Standard, and other
equivalent international best practice systems developed for the control of MHFs,
have been introduced under the Control of Major Hazard Facilities Act 200X and the
Control of Major Hazard Facilities Regulation 200X. The regulatory framework for
control of MHFs in NSW is administered by the Major Hazards Unit (MHU) of
PlanningNSW (formerly the Department of Urban Affairs and Planning).
Major Industrial Hazards Advisory Paper (MIHAP) No. 1 – Overview and Definitions
provides additional background on the National Standard and the relevant NSW
legislation. It is recommended that this document be read in conjunction with
MIHAP No. 1. [To be prepared]

1.2 Purpose and Scope of this Advisory Paper

The purpose of this advisory paper is to provide practical implementation advice
(ie. an explanation of ‘what to do’ and ‘how to do it’) on the hazard identification, risk
assessment and risk control processes for MHFs. This MIHAP is primarily intended
for Operators of MHFs.

Meeting the objective of accident prevention starts with the facility Operator
identifying and assessing hazards and implementing control measures to reduce the
likelihood and effects of a major accident. The hazard identification, risk assessment
and risk control processes, which are included under Section/s [To be Inserted] of the
Control of Major Hazard Facilities Act 200X and clause/s [To be Inserted] of the Control
of Major Hazard Facilities Regulation 200X (Refer to Section 2), build upon the
requirements proposed by the NOHSC in Section 6 of the National Standard.

The scope of this document is limited to the provision of practical technical guidance
on the expectations of the MHU with respect to:

• Identification of hazards and initiating events that could lead to a major accident;

• Identification of the type, likelihood and consequences of major accidents;

• Analysis and assessment of major accident risks;

• Identification of measures to control major accident risks (consistent with the
hierarchy of controls); and

• Risk communication.

Hazard identification, risk assessment and risk control identification are central to the
process for control of MHFs (Refer to Figure 1). Several additional MIHAPs may need
to be consulted to address related issues that are outside the scope of this MIHAP. In
particular, both MIHAP No. 4 and MIHAP No. 5 should be consulted at an early stage.
The findings of the hazard identification, risk assessment and risk control process are
a key input to the Operator’s Safety Improvement Program (SIP), which is described in
MIHAP No. 5 – Safety Reporting. Other documentation relating to the hazard
identification, risk assessment and risk control process that must be submitted to the
MHU as part of the Safety Report is also outlined in MIHAP No. 5, together with the
relevant assessment criteria.

Guidance on Safety Management Systems (SMS) for MHFs (which are important for
ensuring implementation and ongoing management of the identified control
measures) is provided in MIHAP No. 4.

1.3 Process Overview

Figure 1 provides a simplified overview of the process for control of MHFs in NSW
and identifies each of the relevant MIHAPs. The elements most relevant to MIHAP
No. 3 are enclosed by the dark shaded box.
The terms used in Figure 1, and elsewhere in the document, are defined in the
Glossary at the end of this document.
