Definition of Confined Space
A Confined Space is any location or enclosure that presents or has the
immediate potential to present one or more of the following conditions:
• An atmosphere with less than 19.5% or greater than 23.5% oxygen
and/or more than 10 ppm Hydrogen Sulfide (H
2
S)
• An atmosphere that may be flammable or explosive due to gases, vapors,
mists, dusts, or fibers
• Toxic materials which upon contact or inhalation, could result in injury,
impairment of health, or death
Confined spaces are not designed for human occupancy. They have restricted
entry and contain known or potential hazards.
Examples of confined spaces include manholes, stacks, pipes, vats, switch
vaults, and other similar locations.
Standard safety procedures must always be followed prior to entry into
confined spaces and/or locations where hazardous gases, vapors, mists,
dusts, or fibers may be present.
Before entering any confined space check with your employer for procedures
related to confined space entry.
