Confined Space Assessment (Task Specific)
Reference to the NCP Construction Safety Manual 23.3 (1);
‘Confined spaces are identified as any area with a limited means of access / egress and subject to oxygen deficiency, accumulation
of flammable vapors, or any airborne contaminants that exceeds the Permissible Exposure Limits’.
Reference to OSHA 1910.146 Appendix A - refers to 1910.146(b);
“Confined Space”, means a space that;
1. Is large enough and so configured that an employee can bodily enter and perform assigned work; and
2. Has limited or restricted means for entry or exit (For example, tanks, vessels, silos, bins, hoppers, vaults, and pits are spaces
that may have limited means of access & egress.
3. Is not designed for continuous employee occupancy.
“Permit required confined space (permit space)’ means a confined space that has one or more of the following characteristics;
1. Contains or has a potential to contain a hazardous atmosphere;
2. Contains a material that has the potential for engulfing an entrant;
3. 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
4. Contains any other recognized serious safety or health hazard.
