Confined spaces

A confined space is an enclosed or partially enclosed space that is not primarily designed or intended for human occupancy, it has a restricted entrance or exit by way and size, fined spaces as well poor ventilation. Confined spaces can be below or above ground, it can be found in almost any workplace. A confined space, despite its name, is not necessarily small. Examples of confined spaces include silos, vats, hoppers and utility vaults.

The AWS defined confined spaces as having limited space and modes of ingress and egress as well as poor ventilation (American Welding Society, 2003a). While the NIOSH defined confined spaces as sufficient space enough for a person to enter and conduct work, limited means of entry and exit, and does not suit continuous employment. The AWS definition is more restricted than that of the broader (Hammer & Price, 2001).
