Definitions and descriptions

Definitions and Descriptions

  • Job Hazard Analysis (JHA): Proactive, structured method for identification, evaluation, and mitigation or prevention of hazards associated with a particular task.

    • Synonyms: JSA, PHA, etc.

  • Job: A typical “job” includes numerous “tasks”

    • One or more tasks may be hazardous and need a JHA

  • Hazard: Potential for harm

    • Often associated with a condition or activity that, if left uncontrolled, can result in an injury or illness

Why perform a jha

Why perform a JHA?

  • Proactive health and safety management

    • Ensure hazards are recognized so that a company may comply with applicable regulations

    • Provide a safe and healthy place of employment

      • OSHA General Duty Clause

  • Applicable regulatory programs

    • Personal Protective Equipment (PPE)

    • Confined Space

    • Fall Protection

    • Electrical Safety

    • Many others

Why perform a jha1

Why perform a JHA?

  • Proactively identifying risks or hazards before an injury or illness occurs

    • Identify uncontrolled hazards

    • Determine ways to eliminate or reduce hazards & associated risks

    • Implement safety improvements

Why perform a jha2

Why perform a JHA?

  • Training

  • Change management

    • Manufacturing changes in:

      • Process, equipment, chemical, facilities, etc.

    • Legal & other requirements

  • Continuous risk reduction

    • Short-term & long-term objectives

  • Accident investigation

    • Root cause

    • More effective/efficient work practices & procedures

The jha process

The JHA Process

Jha process

JHA Process

  • Select jobs, divide into tasks, and prioritize

  • Review work procedures

  • Observe work & interview employees

  • Complete JHA documentation

    • Risk rank hazards

    • Develop recommended controls

  • Present & review JHA findings with key stakeholders

  • Review recommendations & prioritize

  • Implement agreed-upon safety improvements

  • Update and finalize JHA

Jha process1

JHA Process

Decreasing Risk

  • Risk rank all tasks onsite

    • Prioritized by perceived risk and knowledge of prior hazards

Jha process2

JHA Process

  • Review the process and tasks associated with the job

  • Identify existing safety precautions and hazard controls

    • Engineering

    • Administrative

    • PPE

  • New equipment reviews require additional investigation

    • Manufacturer’s safety requirements

    • Published literature

Jha process3

JHA Process

  • Observe procedures from beginning to end, take pictures, and document:

    • Work practices

    • ALL hazards

    • Current controls

  • Interview Employees

    • Ask about previous and current safety concerns and near misses

    • Ask clarifying questions

    • Open line of communication between workers, their managers, and EHS

Jha process4

JHA Process

  • Compare work performed to procedures specified

    • Identify gaps, shortcuts, or non-documented work-steps

    • Look for inefficiencies and areas of improvement

Jha process5

JHA Process


Complete JHA documentation

Develop recommended controls based on the following hierarchy:

Jha process6

JHA Process

  • Interview engineer(s) and/or supervisor(s)

    • Ask clarifying questions

    • Discuss feasibility of the recommendations

    • Discuss missing information

  • Risk rank tasks to prioritize recommendations

    • Use or develop a defined risk matrix to create risk scores

      • Ex: Severity x Likelihood

Jha process7

JHA Process

  • Present findings and recommendations to

    • Engineer(s)

    • EHS

    • Management

  • Allows management to better understand:

    • Value of the JHA process

    • Work practices & procedures

    • Present hazards & need for controls

    • Scope and resources required

Jha process8

JHA Process

  • Open-forum discussion between all parties

    • Generate ideas from different expertise and varied points-of-view

    • Add missing hazards, controls, and/or recommendations

    • Increases management support for implementation

Jha process9

JHA Process

  • Benefits of working with Senior Management

    • Senior management helps drive project results

    • Accountability to senior management for results

  • Challenges with working with Senior Management

    • Value of proposed solutions

    • High number of recommendations for each hazard

    • Resourcing needs for recommended controls

Jha process10

JHA Process

  • Review feasibility of recommendations with applicable engineer(s) and/or supervisor(s)

  • Prioritize recommendations to focus on critical needs

  • Rank recommendations by feasibility & estimated completion time

    • Process / chemical changes may take years to implement

    • Spec / PPE changes can be implemented in weeks or months

Jha process11

JHA Process

  • Setup schedule for implementation based on:

    • Hazard severity

    • Resources available

    • Return on Investment (ROI)

    • Completion time for the recommendation

  • Management reporting of implementation

Jha process12

JHA Process

  • After implementation and verification

    • Update JHA

    • Recalculate risk

  • Periodic reassessment of potential recommended control options

Process example

Process Example

Process example1

Process Example



Substitute chemical for a less hazardous substance

Keep baths covered

Ventilation improvements

Disposal procedures

PPE modifications

  • Tasks performed around open chemical baths

  • Flammable liquid with potential self-ignition

  • Low-odor and irritant thresholds

  • Hazardous waste generation

  • Non-standard PPE required

Process example2

Process Example


  • Resistance to change increased with higher level of control

    • Significant increase in resources needed

      • Time & money

      • Benefit > Cost?

      • Potential in change to product

Process example3

Process Example


  • Immediate Solutions (EASY - Quick and Cheap)

    • PPE changes

    • Waste disposal requirements

    • Ventilation modifications

  • Chemistry Change ($ and effort)

    • Material cost reduction

    • Benefit in chemical performance

    • Reduced health risks and elimination of odor

    • Elimination of high risk fire hazards

    • Improvement of employee comfort and job satisfaction

In summary

In Summary…

  • JHAs have MANY benefits – more than just finding hazards

  • Imperative to have management support for time & resources

  • Important to rank tasks for implementation phase of project
