Atmospheric Hazards
Many confined space accidents occur because the workers did not realize the dangers or potential dangers within or nearby the space.
Workers may not take into account the new hazards and other conditions created during work in confined spaces. Thus, it is crucial to carefully identify all confined space hazards before entering a space.
Confined Space Hazard Categories
Although confined space incidents are the result of multiple factors, there are two primary categories of hazards:
- Atmospheric - those that involve problems with the air in the space (lack of oxygen, the presence of other gases in the space, etc.); and
- Non-atmospheric - those physical hazards and other conditions caused by equipment, electrical contact, materials, temperature extremes, and surfaces.
It is critical to identify all the hazards in a space and determine how they can impact the health and safety of workers who enter the space.
