Is it really... a "Permit-Required" Confined Space?

OSHA Defines a Confined Space as having all 3 hazards:

Large enough and configured so an employee can enter and perform assigned work.
Has limited or restricted means of entry or exit. Some examples include vessels, tanks, storage bins, silos, hoppers, vaults, and pits.
Is not designed for continuous human occupancy.

Main Difference Between Permit Required and Non-Permit Required

Permit-Required Confined Space: This is a space where the hazards to employees are controlled but still present. These spaces are usually IDLH (immediately dangerous to life and health; i.e., toxic air, no air, uncontrolled energy transmission).

Non-Permit Required Confined Space: This is a space where the hazards are “eliminated” or "controlled".

Permit-Required Confined Space (OSHA Standard 1910.146)

A permit-required confined space is defined by having 1 of any of the following:

Contains or potentially contains a hazardous atmosphere, or
Contains a material that has the possibility of engulfing someone, or
Has a configuration where someone could get trapped or asphyxiated by inwardly converging walls or by a floor that slopes downward and tapers to a smaller cross-section.
Or, contains any other recognized serious safety and health hazard.

Permit-Required Confined Space Hazards include

Mechanical Entrapment (LO/TO, Isolation)
Engulfment Atmospheric (Air Testing)
Gas Temperature Extremes (Testing, Ventillation)
Dust Excessive Noise (Cleaning, Removal, or PPE)
Slick or Wet Surfaces Falling Objects (Wipe up, Dry up, Bracing or Blocking)
Falling Hazards Electrical Shock (Fall Protection, LO/TO)
Poor Lighting or Work Created Hazards (Additional Lighting, JSA)

Host Employers are required to evaluate a space to determine if it is a permit required or a non-permit required confined space. If you need assistance assessing Confined Spaces, contact CFPC's Safety Manager kenreisig@cfpsprinkler.com for a free evaluation.
