Confined Spaces Part 1

1. Confined Spaces � Part 1 An Overview of the Confined Spaces Standard

2. Purpose of This Module This two-part module provides basic information for employers about the hazards of confined spaces, how to control these hazards and what safety requirements apply when employees enter confined spaces. Some employers may elect to contract out confined space work. In those cases, employers are obligated to fully inform contractors of the confined space hazards at their facilities. This overview does not replace the confined spaces standard. For the complete WISHA confined space rule requirements, see Confined Spaces - WAC 296-809.

10. What are the main hazards of confined spaces?

11. Hazard of Confined Spaces When is a confined space so dangerous a written entry permit system is required?

12. Hazardous Atmosphere

13. Hazardous Atmospheres � Flammable Gases, Vapors and Dusts Flammable atmospheres can include methane, or vapors in fuel storage tanks. Certain dusts like grain or flour are also flammable.Flammable atmospheres can include methane, or vapors in fuel storage tanks. Certain dusts like grain or flour are also flammable.

21. Hazardous Atmospheres - Carbon Monoxide(CO)

24. Although we have apparently not had an incident of a worker becoming trapped or engulfed in grain in many years in the State of Washington like you saw in the video, the potential is still there. For that reason, no one should enter a grain bin like the one shown in this slide without a harness and an a second worker standing by.
