Risk Assessment Flashcards
Risk and Insurance Companies
Insurance companies need to be satisfied that the fire risk reduction steps taken are effective and auditable.
Risk and Self-Insured Companies
In some instances companies are self-insured. Those companies then need to be satisfied with the level of risk exposure to the operation, and may prescribe certain risk reduction measures to be implemented across operations – including risks in relation to fire on mobile equipment.
Question:
What is Risk?
Riskis the potential of adverse damage, injury or loss to a person or equipment, asset and/or operation.
Failure to carry out a risk assessment
Will invalidate AS5062:2016 compliance
Before any fire system design is commenced AS5062:2016 states that a fire risk management process must be carried out with the following:
Fire hazard identification
Fire risk analysis
Fire risk evaluation
Fire risk reduction (treating the risks)
Fire risk monitoring and review (ongoing)
The first step in risk process
Identify all potential risks associated with a piece of equipment.
A group review must be completed.
AS5062 states that consideration must be given to the following hazard areas:
Fuel sources and types (Ref AS5062:2016 Section 2.4.2)
Oxidizers (Ref AS5062:2016 Section 2.4.3)
Ignition sources (Ref AS5062:2016 Section 2.4.4)
Hazard locations (Ref AS5062:2016 Section 2.4.5)
Operating environment (Ref AS5062:2016 Section 2.4.6)
Consideration should also be given to the following:
The health and safety of the operator and passengers.
The health and safety of people in the vicinity.
Asset loss.
Property loss.
Production loss.
Environmental damage.
Reputational damage.
Other risk considerations include but are not limited to:
Volume of flammable liquids and lubricants
Materials of construction.
Product being processed or transported e.g. coal dust, chaff, wood chips, etc.
Operating environment e.g. forest, poor emergency access.
Availability of firefighting personnel or external support.
Cleaning materials.
Any oxidizers present e.g. ammonium nitrate.
Chemicals.
Hazard locations include but are not limited to the following areas:
Engine / turbocharger
Fuel and lubrication systems, hoses, pumps, filters.
Hydraulic pumps and piping systems, valves.
Exhaust systems.
Transmission.
Electrical systems, components and wiring.
Braking systems.
Areas where combustible materials accumulate.
Tyres.
Battery systems (EV and hybrid systems).
Question:
Why must we do a risk assessment?
Each type of equipment has a different fire risk profile so we need to ensure all identifiable risks are considered and addressed.
It is a requirement of AS5062:2016

COMMON CAUSES OF FIRE.
Common factors in fires on mobile equipment:
Hydraulic hose failure spraying high pressure oil onto heated components.
Fuel line failures spraying fuel onto heated components.
Oil seal failure leaking oil onto hot engine parts.
Poor maintenance.
Electrical faults.
Mechanical component failures or engine failure (turbo).
Brake drag (park brake partially on).
Bearing seizure.
COMMON CAUSES OF FIRE
A typical heat source
Is the turbo charger, most diesel engines have turbo chargers fitted as standard.
Turbochargers typically run at temperatures up to 1000°C
