3.1.3 Confined space precautions
D A N G E R
Explosion hazard. Training in pre-entry testing, ventilation, entry procedures, evacuation/rescue
procedures and safety work practices is necessary before entering confined spaces.
The information that follows is supplied to help users understand the dangers and risks that are
associated with entry into confined spaces.
On April 15, 1993, OSHA's final ruling on CFR 1910.146, Permit Required Confined Spaces, became
law. This standard directly affects more than 250,000 industrial sites in the United States and was
created to protect the health and safety of workers in confined spaces.
Definition of a confined space:
A confined space is any location or enclosure that has (or has the immediate potential for) one or
more of the following conditions:
• An atmosphere with an oxygen concentration that is less than 19.5% or more than 23.5% and/or a
hydrogen sulfide (H2S) concentration that is more than 10 ppm.
• An atmosphere that can be flammable or explosive due to gases, vapors, mists, dusts or fibers.
• Toxic materials which upon contact or inhalation can cause injury, impairment of health or death.
Confined spaces are not designed for human occupancy. Confined spaces have a 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 obeyed before entry into confined spaces and/or
locations where hazardous gases, vapors, mists, dusts or fibers can be present. Before entry into a
confined space, find and read all procedures that are related to confined space entry.
