another.
The technique is applicable to all
systems which transport or which
control the flow of fluids or energy.
36 Hazard Analysis Generic and specialty techniques to
identify hazards. Generally, and
formal or informal study, evaluation,
or analysis to identify hazards.
Multi-use technique to identify
hazards within any system, subsystem,
operation, task or
procedure.
37 Hazard Mode
Effects Analysis
Method of establishing and
comparing potential effects of
hazards with applicable design
criteria.
Multi-use technique
38 Hardware/Softwar
e Safety Analysis
The analysis evaluates the interface
between hardware and software to
identify hazards within the interface.
Any complex system with hardware
and software.
39 Health hazard
Assessment
The method is used to identify health
hazards and risks associated within
any system, sub-system, operation,
task or procedure.
The method evaluates routine,
planned, or unplanned use and
releases of hazardous materials or
physical agents.
The technique is applicable to all
systems which transport, handle,
transfer, use, or dispose of
hazardous materials of physical
agents.

No. Methods and/or
Techniques
Summary Applicability and Use
Analysis evaluate the human interface and
error potential within the human
/system and to determine humanerror-
related hazards.
Many techniques can be applied in
this human factors evaluation.
Contributory hazards are the result of
unsafe acts such as errors in design,
procedures, and tasks.
appropriate to evaluate any
human/machine interface.
41 Human Factors
Analysis
Human Factors Analysis represents
an entire discipline that considers the
human engineering aspects of design.
There are many methods and
techniques to formally and informally
consider the human engineering
interface of the system.
There are specialty considerations
such as ergonomics, bio-machines,
anthropometrics.
Human Factors Analysis is
appropriate for all situations were
the human interfaces with the system
and human-related hazards and risks
are present.
The human is considered a main
sub-system.
42 Human Reliability
Analysis
The purpose of the Human
Reliability Analysis is to assess
factors that may impact human
reliability in the operation of the
system.
The analysis is appropriate were
reliable human performance in
necessary for the success of the
human-machine systems.
43 Interface Analysis The analysis is used to identify
hazards due to interface
incompatibilities.
The methodology entails seeking
those physical and functional
incompatibilities between adjacent,
interconnected, or interacting
elements of a system which, if
allowed to persist under all conditions
of operation, would generate risks.
Interface Analysis is applicable to
all systems.
All interfaces should be investigated;
machine-software, environmenthuman,
environment-machine,
human-human, machine-machine,
etc.
44 Job Safety
Analysis
This technique is used to assess the
various ways a task may be
performed so that the most efficient
and appropriate way to do a task is
selected.
Job Safety Analysis can be applied
to evaluate any job, task, human
function, or operation.

Techniques
Summary Applicability and Use
Each job is broken down into tasks,
or steps, and hazards associated with
each task or step are identifies.
Controls are then defined to decrease
the risk associated with the particular
hazards.
45 Laser Safety
Analysis
This analysis enables the evaluation
of the use of Lasers from a safety
view.
The analysis is appropriate for any
laser operation, i.e. construction,
experimentation, and testing.
46 Management
Oversight and Risk
Tree (MORT)
MORT technique is used to
systematically analyze an accident in
order to examine and determine
detailed information about the
process and accident contributors.
This is an accident investigation
technique that can be applied to
