Job Hazard Analysis and Job Safety Analysis, Step by Step
Task-level safety done properly. We break a high-risk job into steps, pin the hazard and the control to each one, and hand you a JSA that flows straight into your safe work procedures.
What You Get
What a JSA Delivers
A job safety analysis is the most practical safety tool there is. It turns a risky task into a documented, controlled procedure that the people doing the work can actually follow.
Task Broken Into Steps
The job split into a clear sequence of steps, each describing what is done, so nothing hides between them.
Hazard at Each Step
The specific hazards exposed at every step, from the obvious to the ones only experience catches.
Control at Each Step
A control for every hazard, chosen by the hierarchy of controls, with elimination preferred over PPE.
Feeds Your SWP
The finished JSA drops straight into a safe work procedure and a permit to work.
Why Consultivo
JSA Studies Built by People Who Know the Work
Independence, sector depth and outputs your team will actually use.
IFC World Bank Group approved
The independence and rigour that lenders and international insurers expect for high-hazard operations.
Truly independent
We sell no equipment, software or PPE, so our JSA carries no commercial bias in the controls we recommend.
Practical, not desk-based
Our safety professionals watch the job being done and write controls that hold up on the floor, not just on paper.
Feeds your system
Every JSA is written to flow into your SWPs, permits to work and toolbox talks, not to sit in a folder.
OSHA and ISO 45001 aligned
The method follows OSHA Publication 3071 and supports ISO 45001 hazard-identification requirements.
India and 19+ countries
Cross-industry exposure across 2,000+ organisations and 20+ sectors.
Understanding The Tool
What Is Job Hazard Analysis?
Job hazard analysis (JHA), also called job safety analysis (JSA), is a technique that focuses on job tasks to find hazards before they cause harm. It breaks a job into a sequence of steps, identifies the hazard at each step, and sets a control for each hazard. It looks at the relationship between the worker, the task, the tools and the work environment.
The recognised reference is OSHA Publication 3071, the federal guide to conducting a job hazard analysis. Job hazard analysis, job safety analysis and activity hazard analysis all describe the same process; the name you use depends on your industry.
A JSA is the task-level tool that sits under a wider hazard identification and risk assessment, and both sit within a full process safety management approach.
Full form: Job Safety Analysis (also Job Hazard Analysis). Level: task, one job at a time. Reference: OSHA 3071. Output: a step-hazard-control worksheet that feeds a safe work procedure.
The Method
The 4 Steps of a Job Safety Analysis
Every JSA, in any industry, follows the same four-step logic set out in OSHA Publication 3071.
Select the Job
Prioritise jobs with the highest injury rates, jobs where a single error could be severe, new or modified jobs, and complex tasks that need written procedures.
Break the Job Into Steps
Observe the work and split it into a sequence of steps, each describing what is done, not how. Aim for around 10 to 15 steps.
Identify Hazards at Each Step
For every step, ask what could go wrong, examining the worker, the task, the tools and the environment together.
Determine Controls
Set at least one control per hazard using the hierarchy of controls: elimination, substitution, engineering, administrative, then PPE as the last resort.
Choosing The Right Tool
JSA, JHA and HIRA: What Is the Difference?
These tools work at different levels. JSA and JHA are the same task-level technique under two names. HIRA is broader, and PHA is the process-industry method. Match the tool to the question you are asking.
JSA / JHA, task level
One job, broken into steps, with a hazard and control at each. Feeds a safe work procedure. Two names, same process.
HIRA, area or activity level
All hazards across a work area or operation, scored into a risk register. See hazard identification and risk assessment.
PHA, process level
Hazards in a process design, using HAZOP, HAZID and What-If. See process hazard analysis consultants.
Prioritising
Which Jobs Need a JSA, and When
Not every task needs its own JSA. These are the ones that earn one first.
High-consequence jobs
Tasks where a single error could cause a serious injury or a fatality.
Working at height
Scaffold, ladders, roofwork and elevated platforms, the leading cause of fatalities.
Hot work
Welding, cutting and grinding near flammables, where a permit to work applies.
Confined space entry
Tanks, vessels and pits with atmospheric, engulfment and entrapment risks.
New or modified tasks
Any job that is new, has changed, or uses new equipment.
After an incident
To rebuild the task safely after a near miss or injury.
Our Approach
How Consultivo Conducts Your JSA Study
A structured five-stage approach - practical, independent and built to feed your safe work procedures.
Scope and Prioritise
Agree the jobs to analyse, starting with the highest-risk and permit-to-work tasks.
Observe the Work
Watch the task performed and break it into an accurate sequence of steps with the crew.
Identify Hazards
Capture the hazard at each step across worker, task, tools and environment.
Set Controls
Assign controls by the hierarchy, with an owner for each action.
Document and Hand Over
Deliver the JSA worksheet and the draft safe work procedure ready to use.
Sectors We Serve
Job Safety Analysis Across Every Industry

Questions About JSA and Job Hazard Analysis
What is JSA in safety, and what is the full form of JSA?
JSA stands for Job Safety Analysis, also known as Job Hazard Analysis (JHA). It is a task-level technique that breaks a specific job into steps, identifies the hazard at each step, and sets a control for each hazard. It focuses on the relationship between the worker, the task, the tools and the environment, and the finished JSA feeds a safe work procedure.
What is the difference between JSA and JHA?
There is no difference in method. JSA (Job Safety Analysis) and JHA (Job Hazard Analysis) are two names for the same task-level process. OSHA uses JHA in its official guidance, while construction, oil and gas and many other industries say JSA. Activity Hazard Analysis (AHA) is a third name for the same thing.
What is the difference between JSA and HIRA?
A JSA is a task-level tool that analyses one specific job step by step. HIRA (Hazard Identification and Risk Assessment) is broader, covering all hazards across a work area, process or operation and producing a scored risk register. A JSA is more granular and feeds into safe work procedures; HIRA is used for wider safety planning and ISO 45001 compliance. Consultivo conducts both.
What are the steps of a Job Safety Analysis (JSA)?
A JSA has four steps: (1) select the job, prioritising high-risk and complex tasks; (2) break the job into a sequence of steps; (3) identify the hazards at each step; and (4) determine a control for each hazard using the hierarchy of controls. The result is a step-hazard-control worksheet, as set out in OSHA Publication 3071.
Which jobs need a JSA?
Prioritise jobs with the highest injury rates, jobs where a single error could cause a severe injury or fatality, new or modified jobs, and complex tasks that need written instructions. High-risk activities such as working at height, hot work and confined space entry should always have a JSA, and one should be revisited after any incident.
Do you provide a JSA for working at height and other high-risk tasks?
Yes. We prepare job safety analyses for working at height, hot work, confined space entry, lifting operations, energy isolation and other high-risk activities, each written to support the relevant permit to work and to feed a safe work procedure your team can follow.
