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:
All manuals and user guides at all-guides.com
• An atmosphere with an oxygen concentration that is less than 19.5%
or more than 23.5% and/or a hydrogen sulfide (H
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.
