| | | Confined Space/Permit-Required Confined Space < on 1/29/2004 5:35 AM >
| | | A confined space is a space large enough and so configured that someone can enter and perform assigned work; and has limited or restricted means for entry or exit (for example, tanks, vessels, silos, storage bins, hoppers, vaults, and pits are spaces that may have limited means of entry.); and is not designed for continuous employee occupancy. There are two types of confined spaces: 1. Non-Permit Required Confined Space - is a space that meets the definition of a confined space but does not contain or, with respect to atmospheric hazards, have the potential to contain any hazard capable of causing death or serious physical harm. 2. Permit Required Confined Space - this is a confined space that meets the definition of a confined space but has one or more of the following characteristics: a. Contains or has a potential to contain a hazardous atmosphere; b. Contains a material that has the potential for engulfing an entrant; c. Has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross-section; or d. Contains any other recognized serious safety or health hazard. Examples of serious safety or health hazards might include: Fall hazards Unguarded machinery Extreme heat or cold Steam pipes or chemical lines Hazardous noise levels Electrical hazards Presence of asbestos Potentially hazardous levels of dust Confined spaces can be hazardous for several reasons: a. Hazardous atmospheres - the nature of many confined spaces can cause them to have poor atmospheres such as a lack of oxygen, flammable gases, toxic gases, etc. b. Engulfment / Entrapment - the space has the potential for a material in the space to collapse and trap or bury the employee inside of the confined space c. Restricted Entry - spaces are not made for continuous occupancy by humans and may have limited entry and exit places. d. Occupational Hazards - occupational hazards are amplified in confined spaces. Noises are louder because they cannot escape into the atmosphere. Heat builds up quickly and can lead to heat exhaustion. Besides all that, Confined Spaces can be alot of fun to explorer! Examples of Confined Spaces: -Sewers (storm sewer, combined sewer overflows, sewage drain) -Public Utility Tunnels -Steam Tunnels -Crawl Spaces ..Etc See Also: Drain Steam Tunnel Asphyxiant Hydrogen Sulfide Methane SCBA For Info On Asbestos Also See Asbestos
