Definition
A “Confined Space” is a space which has all three of the following characteristics:
- Large enough for an employee to enter and perform assigned work; and
- Has limited or restricted means for entry or exit; and
- Is not designed for continuous employee occupancy.
Classification
All confined spaces must be evaluated and classified as a non-permit or permit-required confined space. A non-permit required confined space meets the definition of a confined space but does not have any additional known or potential hazards. A permit-required confined space (PRCS) is a confined space with one or more actual or potential hazards e.g., entrapment, engulfment, or hazardous atmospheres.
Space Identification
All permit-required confined spaces need to be identified with appropriate labeling/signage. Signage for non-permit confined spaces is not required, however, it is recommended for spaces that may be accessed by untrained personnel.
Training
All personnel involved in confined space work are required to receive appropriate training in hazard recognition, personal protective equipment, safety equipment, communications equipment, procedures for calling rescue services and proper use of non-entry rescue equipment as needed.
Specialized training is required based upon an individual’s role (e.g., Entry Supervisor, Authorized Entrants) when entering a PRCS.
Confined Space Entry
Confined space entry procedures are defined for non-permit and permit-required areas. PRCSs require completion of permit entry forms as needed.
