Non-Permit Required Confined Spaces

Two options for entry into a permitted confined space

Option 1 – Reclassification of the Confined Space
The OSHA standard states:
“A space classified by the employer as a permit-required confined space may be
reclassified as a non-permit confined space. If the permit space poses no actual or
potential atmospheric hazards and if all hazards within the space are eliminated without
entry into the space, the permit space may be reclassified as a non-permit confined space
for as long as the non-atmospheric hazards remain eliminated.”

This is considered a C7 reclassification (C7 refers to the applicable paragraph in the OSHA
standard.)

Reclassification requires:
1. No Actual or potential atmospheric hazards in the space
2. Safety hazards can be eliminated without going into the space
3. The employer must monitor/inspect the confined space and record data supporting use of
non-permit entry procedures

NOTE 1: Control of atmospheric hazards through forced-air ventilation does not
constitute elimination of the hazards.

NOTE 2: The employer must document the basis for determining that all hazards in a
permit-required confined space have been eliminated through a certification that
contains the date, the location of the space and the signature of the person making the
determination. The certification must be made available to each employee entering the
space or to that employee’s representative.

NOTE 3: Reclassified of a permit-requires confined space does not automatically make
it reclassified for the next entry operation. Each entry operation must be assessed,
rendered safe and certified before it can be reclassified as a non-permit required space.

Option 2 – Alternate Entry Procedures
Employees needing to enter a permit-required confined space can utilize an alternate entry
procedure if it can be demonstrated that the only risk associated with the confined space is an
actual or potential hazardous atmosphere and the space can be made safe for entry.

Alternate Entry Requires the Following:
1. Any potential or actual hazardous atmosphere must be controlled (made safe) by
continuous forced-air ventilation and the atmosphere assessed to be safe for entry.
Ventilation alone must ensure that the space can be made safe for entry.
2. There must be no safety hazards associated with the entry process.
3. The employer must monitor/inspect the confined space and record data supporting use of
the alternate entry procedures.
