Describe the Hazards in Each Step

Introduction

A very important part in the JHA development process is to discover the hazards lurking within each step. A basic safety concept must be understood by all safety staff: to have an accident, a hazard and exposure to the hazard must exist.

Look for possible hazards in each step.
  • A hazard is an unsafe condition that could cause injury or illness to an employee.
  • Exposure usually refers to an employee's placement relative to the hazard's "danger zone". If the employee is within the danger zone, the employee is exposed.

How To Identify Hazards

Whoah! Where's the guard?

A job hazard analysis is an exercise in detective work. Your goal is to discover the following:

  • What can go wrong?
  • What are the consequences?
  • How could the hazard arise?
  • What are other contributing factors?
  • How likely is it that the hazard will occur?

To make your JHA useful, document the answers to these questions in a consistent manner. Describing a hazard by answering the questions above ensures you target the most important contributors to the hazard. The hazard column in your JHA should identify the hazards, and the potential for exposure to hazards.
