Job Hazard Analysis (JHA) Overview

Job Hazard Analysis (JHA) Overview

What is a Job Hazard Analysis (JHA)?

A JHA is a method for identifying and evaluating hazards associated with tasks (steps) with a specific job or activity and eliminating or mitigating them prior to starting work.

Why conduct a JHA?

A JHA can prevent work-related injuries or illnesses by eliminating or controlling identified hazards. It is a means to ensure that workers have the training, equipment, and supplies to do their jobs safely.

Who should conduct a JHA?

Individuals who perform the tasks that are being evaluated. Supervisors shall review the JHA with their employees prior to starting job.

Procedure for Completing a Job Hazard Analysis

Job or Task Description: Define the job or activity.
Sequence of Job Tasks: Break down the job or activity into tasks (steps). A single task can be the combination of minor actions.
Hazards and Consequences: For each task identify all of the hazards and consequences that could occur. Think about the inherent hazards of the material, equipment or activity; what could go wrong (failures and/or modes of failure); what is worst-case consequence.
Ladder work - severe injury, fatal fall Poor housekeeping – congestion; slip, trip, or fall; injuries Machinery – moving parts; amputation Flammable Liquids – vapors; fire/explosion Hazardous materials - uncontrolled spill/release Noise - hearing loss Electricity - shock and/or arc flash Dusts, fumes, mists, or vapors in air - inhalation Oxygen displacement - asphyxiation Confined space - hazardous atmosphere; engulfment; fatality Portable tools – projectiles; eye injury Contact with hot, toxic, or caustic chemical/product - burn, injury	Biological exposure - infection Repetitive tasks - Musculoskeletal Disorder (MSD) injury Strain from lifting, pushing, or pulling - MSD injury Working in awkward position - MSD injury Lighting problem - seizures, headache Falling object – struck by; injury Radiation - exposure Weather conditions affect safety Thermal – cold/heat - burn, dehydration Other Other Other

Controls (Prevention Measures): Identify existing controls to eliminate or mitigate the potential hazard/consequence scenario. If the consequence is severe, try to use inherently safe controls or engineering controls and multiple controls to mitigate the risk. Some controls can help prevent the likelihood of the accident scenario by preventing the occurrence or reducing the severity of the consequence.

Inherent Safety

Elimination

Substitution

Process changes (reduce volume, changing operating parameters, etc.)

Engineering

Secondary containment (berms, vaults)

Install guards on machine moving parts

Use scaffold or lift instead of ladder

Ventilate the area

Detection and alarm systems (interlocks and notification)

Use platform ladder instead of regular step ladder

Guardrails (permanent or temporary)

Emergency showers/eyewash

Pressure relief

Isolate the area (barriers)

Insulate noisy equipment

Fire protection - sprinklers and alarm

Fire extinguisher

Other

Safe Work Practices and Administrative

Safe work practices

Standard Operating Procedures (SOP)

JHAs

Work permits (LOTO, CSE)

Use tool lanyards at heights

Reduce exposure time

Training

Spill kits

Emergency response team

Exposure control plan

Other

Personal Protective Equipment (PPE)

Safety glasses/goggles/face shield

Gloves (specify type)

Skin protection (lab coat/Tyvek suit)

Respiratory protection

Personal fall protection equipment

Hearing protection

Hard hat

Impact/radiation shielding

Other

Use JHA template form to complete the JHA: In addition to listing the hazards/consequences and controls for each job step, list the required training and PPE.
