A confined space is one that is large enough to enter and perform assigned work in; it has limited or restricted ways to enter or exit the space; and it was not designed to be occupied continuously by a worker. A permit space is a confined space that has one...
Confined spaces frequently contain atmospheres that are flammable, toxic, or whose oxygen level has been depleted or enriched. Natural ventilation is generally insufficient to remove contaminated air from the inside space and to exchange it for fresh air from the outside. The lack of air exchange occurs particularly in confined...
Confined spaces frequently contain atmospheres that are flammable, toxic, or whose oxygen level has been depleted or enriched. Ventilation is the number one way for workers to control and disperse hazardous atmospheres in a confined space. The prime objective in ventilating a confined or enclosed space is to render it...
Confined spaces present a special type of danger – a danger that you may not recognize until you’ve already entered a confined space and encountered the hazard. By then, it may be too late. Toxic gases, lack of oxygen, shifting materials inside, and other hazards can cause injury or death...

Atmospheric Testing in Confined Spaces Atmospheric testing is required for two distinct purposes: evaluation of the hazards of the permit space and verification that acceptable conditions exist for entry into that space. Evaluation testing: The atmosphere within a confined space must be tested using equipment that is designed to detect...

Confined Space Entry – Don’t Be a Dead Hero You are standing at the top of an open manhole, acting as attendant for a team of maintenance personnel who have entered a permit-required confined space. It has been several minutes since you talked to the crew, but you can peer...
