Introduction
•
This seminar is a basic introduction to the Safety Report that
is required under the MHF Regulations.
•
It has been developed for the following purposes:
–
–
–
–
–
To provide a simple overview
To be suitable for new MHF Employers
Outline the reason for a safety report
Overview of all parts of a safety report
Show examples of major accidents
5
Key Principles of MHF Regulations
•
•
•
•
Focus on major hazards (catastrophic events i.e. typically
high consequence and low frequency)
Requires a proactive risk based approach
Places the responsibility on the Employer
Employer has to actively demonstrate safe operation
6
Key Principles of MHF Regulations
•
•
•
•
Consultation with different parties required at all critical
stages
Facilitate culture change at major hazard facilities
Regulator ‘peer review’, tied to a licence
Addresses both on-site and off-site safety
7
Focus of MHF Regulations
Increasing risk
Relative Frequency of Occurrence
Minor
risks
OHS risks
already
regulated
Very high risks
should already
be eliminated
after risk
assessment
Focus of MHF
Regulations is
high consequence
(catastrophic)
but low frequency
incidents
Consequence Severity
8
Objective of the MHF Regulations
• The objective of the MHF Regulations is to provide for the safe
operation of major hazard facilities to:
–
–
Reduce the likelihood of an MA occurring
Reduce the consequences to health and safety and damage to
property in the event of an MA occurring
9
MHF Regulations
Specific parts of the MHF Regulations relevant for this seminar are:
•
•
•
•
•
•
Hazard identification (9.43)
Risk assessment (9.44)
Risk control measures (9.45)
Safety management system (9.46)
Emergency planning (9.53)
Provision of information to the community (9.50)
10
Why is a Safety Report Needed?
There is a need for specific control of major hazards due to:
•
•
•
•
•
Changing scale and complexity of specific facilities
Advances/changes in technology - unforeseen hazards
Changing community perceptions
Range of major accidents that have occurred
Prescriptive approach has proven inappropriate
11
Why is a Safety Report Needed?
Some major accidents that have occurred
•
•
•
•
Coode Island, Australia – storage terminal fire, August 1991,
0 dead, 0 injured
Longford, Australia – explosion and fire, September 1998, 2
dead, led to the development of Victorian MHF legislation
Entschede, Holland – fireworks factory explosion, May 2000,
21 dead, 1,000 injured
Texas City, USA – fire and explosion, March 2005, 15 dead,
over 170 injured
12
Why is a Safety Report Needed?
Port Kembla Ethanol Tank Fire, NSW, Australia, 28th
January 2004
Quote from the Coroner…“not a lack of adequate safety procedures but rather
the failure to adhere to them”.
(Welding was carried out in an unsuitable area without a ‘hot work’ permit)
13
Why is a Safety Report Needed?
This has led to Regulations where:
•
•
•
The Employer knows what technical and human activities
occur
The Employer decides on the appropriate means of major
hazard control for the facility, and prepares a Safety Report
explaining this
The Regulator assesses and audits performance adequacy
against the safety report
14
Why is a Safety Report Needed?
•
The introduction of
regulations were ‘fast
tracked’ in Victoria primarily
as a result of the Royal
Commission into the
incident at Longford in
1998.
•
The Victorian MHF regime is
now mature and is working
well.
15
What is the Safety Report?
•
The safety report must address all hazardous events that
could result in MAs that pose serious danger or harm to:
–
–
–
–
Persons
The community
Property
The environment
16
What is the Safety Report?
•
A safety report is a detailed document that outlines:
–
–
–
–
The
and
The
The
The
identification and control mechanisms in place to prevent
mitigate all MAs for the facility
types of safety studies undertaken
results obtained for such studies
management arrangements in place
to ensure the continued safety of the facility and its people
and the surrounding community.
•
The safety report must be prepared in consultation with
employees and be a true reflection of the state of the safety
arrangements for the facility.
17
What is the Safety Report?
The Role of the Safety Report
•
Regulatory role: The primary document used by an approved
assessor to verify that the facility is operated safely to
support the Employer’s licence application.
•
Information Repository: Contains all information about the
safe operation of the facility which contributes to continuous
improvement of safety at the facility.
18
What Must the Safety Report Do?
•
Document the state of safety arrangements for the facility
•
Demonstrate to the satisfaction of the Commission, through
content and supporting material, that:
–
–
–
The employer knows what technical and human activities occur
How activities are managed
How safety will be managed in the event of an emergency
19
What Must the Safety Report Do?
Identify methods to be used
for monitoring and
reviewing all activities for
continual improvement of
the safety arrangements of
the facility over its lifetime.

20
The Safety Report Should…
•
•
•
•
•
•
Reflect the facility safety culture
Contain information about the facility and interaction with its
surroundings
Describe the systems used to achieve safety
Identify, assess and show controls for potential major
accidents
Demonstrate ongoing consultation between the employer and
workforce
Be integrated into the Employers management systems rather
than a collection of separate individual safety studies

measures that eliminate or reduce as
far as practicable the risk to health
and safety. This relates to both the
likelihood of the potential Major
Accident and the severity of the
consequences.

43
Review & Revision
•
Employers must review (and revise) the safety report for an
MHF to ensure risks remain reduced AFAP:
–
–
–
–
–
Prior to modification
When new information becomes available regarding possible MA
hazards previously unknown
Upon licence renewal conditions or at least every 5 years
At the direction of the Commission
After a major accident
44
Conclusion
•
•
•
The safety report must demonstrate adequacy of all Safety
Duties required by the MHF regulations
Safety Duties are ongoing requirements
An Employer at a MHF who fails to comply with the MHF
regulations may be subject to civil proceedings or criminal
prosecution under the OHS Act.

Several examples of incidents are available. These include:
1. Tosco Avon refinery fire incident, Martinez California, 23rd
February 1999 (source: U.S. Chemical Safety and Hazard
Investigation Board, Report No. 99-014-1-CA, issue date
March 200)

48
Buncefield Incident (UK) – December 2005.
•
In the early hours of
Sunday 11 December 2005,
a number of explosions
occurred at Buncefield Oil
Storage Depot, Hemel
Hempstead, Hertfordshire
•
At least one of the initial
explosions was of massive
proportions and there was a
large fire, which engulfed a
high proportion of the site
•
Over 40 people were
injured; fortunately there
were no fatalities
49
Buncefield Incident
Off-Site Consequences
•
•
•
•
•
“Significant damage” to commercial and residential
neighbours
2000 people evacuated
Sections of M1 Motorway closed
Very large smoke plume over Southern England → Air
pollution
Large quantities of foam and water → contaminated water
courses and ground water
50
Buncefield Incident
•
HSE/EA investigation determined the direct cause (initiating
event) as follows:
–
–
–
•
•
•
“Tank 912 ……. overflowed at around 05.30 hours …….. while
being filled at a high rate”
Large vapour cloud formed and flowed off-site
First explosion at 06.01 hours
There were multiple root causes (failures) identified
Many related to management system failures
Still some unanswered questions
–
Why was there so much explosive force?

Buncefield Fuel Storage – before incident
52
Buncefield – during the incident
53
Buncefield – after the incident
54
Dubai Dry Dock Incident
•
On 27 March, 2002 in Dubai there was a breach and failure in
one of the dock gates that caused uncontrolled flooding in the
dry dock.
•
Several vessels were set on blocks inside the dry dock at the
time of the failure. The vessels included the large vessel "Key
Burmuda," a cargo barge and the accommodation barge "SEP
350“.
55
Dubai Dry Dock Incident
•
The dry dock gates failed at 09.30 during a working day.
•
The dock is 500 metres long by 100 metres wide and 11
metres deep.
