Overview

“Confined Space Hazards” is designed for all employees who work around permit-required confined spaces, but not necessarily in a permit-required confined space.

If you have any permit-required confined spaces on your site, each of your workers needs to complete this training program. This course will define a permit-required confined space and discuss all of the hazardous aspects of confined spaces.

Your workers will learn about confinement, atmospheric and process hazards. They will also learn about hazard control and the permit program.

This course features fifty-two interactions and practice activities.

Confinement Hazards
* Entry and Exit Dangers
* Difficult to Occupy
* Part of a Process

Atmospheric Hazards
* Entering the Space’s Atmosphere
* Asphyxiating Atmospheres
* Toxic Atmospheres
* Flammable Atmospheres

Process Hazards
* Energy-related Hazards
* Content-related Hazards
* Other Hazards

Hazard Controls
* Isolation
* Purging, Cleaning, and Ventilation
* Protective Equipment
* Work Practices

Permits
* The Permit Program
* The Permit Checklist
