HITRA Transition and Communication Pack 1
HITRA Transition and Communication Packs
BPXA HITRA Transition and Communication Packs
• In support of transition from current risk assessment
practices to HITRA or Hazard Identification Task Risk
Assessment.
• To supplement the OE HITRA Training.
These HITRA Transition and Communication Packs include:
− Sources of Energy (SoE)
− Jobs, Tasks, and Task Steps
− Hazards, Consequences, Controls
Today we
will cover??
− HITRA Transition Summary

Objectives
• Why Change to HITRA?
• HITRA Sources of Energy requirements
• Why we use Sources of Energy in the HITRA process
• Using Hazards Types (Lenses) and Sources of Energy to apply HITRA
• Differences in HITRA Sources of Energy vs. Decision Point
• Review of all of the Sources of Energy used in the HITRA process
• A look at the 10 Sources of Energy…
− on the new L1 Task Risk Assessment form

Alaska Region: Why Change Now?
• To align BPXA Risk Assessment Processes with Upstream practice.
• HITRA is a mindset of how we will conduct risk assessments and is the
way we do business
• Systematic (repeatable and reproducible); common language (uses
Task Risk Assessment Table (TRAT))
• This is how e-CoW documents Risk Assessments; e-CoW will be
simpler, include better options, and one technique covering all tasks;
− L1 & L2 TRA for all permitted work
− Once a L1 or L2 TRA has been created it may be utilized again for the
same or similar task
− Option for low risk (routine) work based on a risk assessed procedure,
approved annually
− Used for Non-permitted work
Risk Assessment is a primary focus area for BPXA.
– CoW incidents are still high as a result of inadequate risk assessment

Hazard Identification and Task Risk Assessment
HITRA
Identifying Hazards using Sources of Energy
Focus on
the Trap
not the
Cheese
Mechanical - includes mobile
equipment, as well as moving
parts on stationary equipment and
rotating equipment.

Using 10 Sources of Energy (SoE)
• An expectation of HITRA is that we always consider the 10 Sources of
Energy (SoE) to systematically identify hazards
− To assist in ensuring all credible hazards are identified
• All Hazards can ultimately be traced to Energy Sources
 All HIPOs, near misses, and incidents can be traced back to
Sources of Energy (SoE) as well!
• The 10 Sources of Energy should be applied to each hazard type
(identifying hazards through 3 lenses)
− Task
− Job Site
− Process

New Sources of Energy
Body Mechanics
• Human strength and agility applied to a task involving
lifting, pushing, pulling, climbing, or positioning.
• Ergonomic considerations.
Noise
•
•
•
•
A form of pressure energy.
High noise area.
Tools/equipment with high noise decibels.
Communication problems, including emergency.
All other Energy Sources remain the same.

The 10 Sources of Energy
Biological - covers the many sources of energy in life forms,
including wildlife and viruses or bacteria, e.g. as found in sewage
systems, drain lines, cooling towers.
Body Mechanics – human strength and agility applied to a task
involving lifting, pushing, pulling, climbing or positioning.
Chemical - energy in the form of reactive or life-threatening gases,
liquids, solids, e.g. water, methane, nitrogen, process chemicals, etc.
Electrical - includes all types and voltages of electricity including high
voltage power systems (AC), battery systems (DC) and static.
Consideration should be given to include indirect impacts, i.e. static
charge, electrical equipment, power lines.
Gravity - a naturally occurring energy. Fluid weight, the gravitational force
acting on a column of fluid.
9
The 10 Sources of Energy - continued
Mechanical - includes mobile equipment as well as moving parts on
stationary equipment and rotating equipment.
Noise – a form of pressure energy.
Pressure - air, water, pneumatics, springs, gases are all possible sources
of significant pressure energy. Consideration should be given to sections
of equipment in which trapped or un-drained contents may remain.
Radiation - ionising radiation, arc flash (radioactivity).
Thermal - energy associated with hot or cold surfaces and fluids, undesired
chemical reactions and/or ambient temperatures.
