CONFINED SPACE ENTRY PROCEDURE POLICY
VILLAGE OF NASHVILLE
October 14, 2005
Purpose
The purpose of this document is to communicate the Village of Nashville’s compliance with MIOSHA requirements for a permit-required confined space entry and to outline the Village of Nashville’s confined space entry program.
The Village of Nashville has
identified all permit-required confined spaces at this location and has determined entry and rescue procedures.
This document contains:
·
the employer’s procedures for permit-required confined
space entry,
·
the names of the entry supervisors trained to issue permits,
·
the names of all employees (authorized entrants) trained
to enter permit-required confined spaces or serve as attendants,
· the names of the trained rescue and emergency service members.
In addition, the document specifies:
·
all personal protective equipment (PPE), air monitoring
equipment, and rescue equipment that employees use at this location.
· the Village of
Nashville’s responsibilities to contractors
and the contractor’s duties to the Village
of Nashville.
Scope and Application
The Village of Nashville defines a permit-required confined space as a space that has all four (4) of
the following characteristics:
1. It is large enough and has a configuration that allows an employee to bodily enter it and perform
assigned work; and
2. It also has limited or restricted means for entry or
exit; and
3. It is not designed for continuous employee occupancy, and
4.
It has one or more of the following characteristics:
· It contains, or has a potential to contain a hazardous atmosphere,
·
Contains a material with the potential for engulfing
an entrant,
·
Has an internal configuration such that an entrant could
be trapped or asphyxiated by inwardly converging walls, or a floor which slopes downward and tapers to a smaller cross-section,
or
·
Contains any other recognized serious safety or health
hazard.
Administrative Measures for Preventing Unauthorized
Entries Into Permit-Required Confined Spaces
The Village of
Nashville has taken administrative measures
to prevent unauthorized entries. These measures include the use of signs, barriers, covers, guardrails, fences, and locks.
Entry supervisors will remove unauthorized individuals who enter or attempt to enter the permit-required confined
spaces.
Attendants will advise unauthorized persons that they must exit immediately if they have entered the PERMIT-REQUIRED
confined space. Attendants will also inform authorized entrants and the entry supervisor if unauthorized
persons have entered the PERMIT-REQUIRED confined space
It is the responsibility of the individual(s) entering a PERMIT-REQUIRED confined
space to be sure they have been issued a PERMIT-REQUIRED confined space entry permit. Entering permit-required confined space
without a permit or required training is an unauthorized entry and violates the Village of Nashville’s
policy.
Identification and Evaluation of Permit-Required Confined Spaces
The Village of Nashville has
conducted a survey of this facility and determined that the following locations are PERMIT-REQUIRED Confined Spaces.
Employer performed an analysis to determine the hazards, entry procedures, protective equipment required, rescue and emergency
services necessary.
·
INSERT LIST (DPW must complete this list)
Entry supervisors will review the analysis
for the location for which they are to issue a permit.
An analysis of each PERMIT-REQUIRED confined space at this facility follows this
section.
Means, Procedures, And Practices
It is the responsibility of the Village of Nashville to issue permits and
to enforce compliance with PERMIT-REQUIRED confined space entry procedures.
The Village of Nashville has trained entry supervisors in the skills necessary to issue permits.
The entry supervisor is responsible
for testing the atmosphere and evaluating the hazards the PERMIT-REQUIRED confined space. The entry supervisor will place
the written permit at the entry point into the PERMIT-REQUIRED confined space prior to entry.
The entry supervisor will make certain that employees comply with
the following means, procedures, and practices for safe permit space entry operation.
Acceptable Entry Conditions
The entry supervisory
shall test the PERMIT-REQUIRED confined space for acceptable entry conditions.
Acceptable Entry Conditions Are:
· more than 19.5%, but less than 23.5% oxygen, and
· less than 10% of the Lower Flammable Limit (LFL) of a flammable liquid or gas, and
·
not to exceed the Permissible Exposure Level (PEL) of
a toxic chemical.
Isolation and Lockout
The entry supervisor shall assure the isolation of the permit-required confined space from serious
hazards. Mechanical equipment that poses a hazard in the space must be “locked out” accordance with the MIOSHA
General Industry Standards. Chemical or gas lines that are open within the permit space must be isolated by appropriate means.
These include blanking, misaligning or removing sections of lines, pipes, or ducts, or a double block and bleed system.
Atmospheric Hazards
The entry supervisor
will assure adequate purging, inerting, flushing, or ventilation of the space before authorized entrants enter a permit-required
confined space. This is accomplished by ventilating the atmosphere, after purging, if the space is a flammable liquid container
or if purging is otherwise necessary, before an authorized entrant enters the space.
Inerting is the displacement of the atmosphere in
a permit space by a noncombustible gas to such an extent that resulting atmosphere is noncombustible. This procedure produces
an IDL oxygen-deficient atmosphere. The entry supervisor must ensure proper respiratory protection provided to the authorized
entrant before entering the permit space using this procedure.
Barriers
The entry supervisor will provide (if applicable) for barriers
around the permit space opening to:
· prevent unauthorized entry into the space, and
· protect authorized entrants inside the space from objects and persons outside the space.
Verification
The entry supervisor
will assure that conditions in the permit space are acceptable for entry throughout the duration of entry operations. To accomplish
this, the supervisor will
use
calibrate test instruments to monitor the atmosphere within the space and make inspections to assure that isolation is being
maintained for the space.
Attendant
The entry supervisor will provide at least one attendant outside the permit space into which entry is authorized for the duration of entry operations.
NOTE: An entry
supervisor who receives adequate training may serve as the attendant.
Personal Protective Equipment
(PPE)
The Village of Nashville will provide any personal protective equipment (PPE) necessary for safe entry into and rescue
from permit-required confined spaces at no cost to employees. The Village of Nashville will
maintain that equipment properly and assure that employees use it
properly.
Permit-Required Confined Space equipment program includes:
· testing and monitoring equipment
· ventilation equipment
· communications equipment
· lighting equipment
· barriers
and shields
·
ingress and egress equipment
· rescue and emergency equipment
· FFE
· any
other equipment necessary for safe entry into and rescue from permit spaces.
Evaluation of Permit Space conditions
The entry supervisor
will evaluate permit-required confined space conditions as follows when entry operations take place. The entry supervisor
will:
·
Test conditions in the permit space to determine if acceptable
entry conditions exist before entry is authorized.
If it is not feasible to isolate the space because the space is large or is part of a continuous system,
pre-entry testing shall be performed to the extent feasible before entry is authorize Entry conditions shall be monitored
in the areas where authorized entrants are working.
· Test or monitor the permit space as necessary to determine if acceptable entry conditions a being maintained during
the course of entry operations.
· When testing for atmospheric hazards, test for oxygen first, then flammables (LFL), and then for toxic substances
(PEL).

Preparation, Issuance, Use, and Cancellation of Entry
Permit
Permit
System
Before
entry begins, the entry supervisor identified on the permit shall sign the entry permit to authorize entry,
The permit shall be made available
to all authorized entrants, by posting it at the confined space opening or by any other equally effective means. This enables
entrants to confirm the pre-entry preparations are complete.
The duration of the permit may not exceed the time required to complete the task
or job identified on the permit in accordance with the purpose of the entry. The duration of the permit can not exceed one
shift. If the job requires two shifts for completion, then at least two permits are necessary.
The entry supervisor should terminate
entry and cancel the permit when:
· The
entry operations that the entry permit covers are complete; or
· A condition that the entry permit does not allow arises in or near the permit space.
Any individual designated as the entry
supervisor has the authority to terminate entry and cancel a permit.
The Village of Nashville shall
retain each canceled entry permit for at least one year to facilitate the review the permit-required confined
space entry program. The entry supervisor should note any problems encountered during an entry operation on the appropriate
permit so that revisions to the permit space program can be made.
Entry Permit
The entry permit that documents compliance and authorizes
entry to a permit space should identify:
1. The permit space to be entered;
2.
The purpose/reason of the entry;
3. The date and the authorized duration of the entry permit;
4.
The authorized entrants within the space, by name, as this will enable the attendant to determine quickly and accurately,
for the duration of the permit, which entrants are inside the space;
5. The personnel,
by name, currently serving as the attendant(s);
6. The individual, by name, currently
serving as the entry supervisor, with a space for the signature or initials of the entry supervisor who originally authorized
entry;
7. The potential or real hazards of the space to be entered;
8. The
measures used to isolate (lockout) the permit space and to eliminate or control permit space hazards during entry;
9.
The acceptable entry atmospheric conditions;
10. The results of initial and periodic air monitoring tests performed, accompanied
by the name or by an indication of when the tests were performed;
11. The rescue
and emergency services that can be summoned and the means for calling those services;
12. The communication procedures used by authorized entrants
and attendants to maintain contact during the entry operations;
13. The equipment, such as PPE, air testing equipment, communications equipment,
alarm systems, and rescue equipment to be provided.
14. Any other information whose inclusion is necessary, given the circumstances of the particular confined
space, in order to ensure employee safety; and
15. Any additional permits, such as for hot work, that have been issued to authorized work in the permit
space.
A
copy of the Village of Nashville entry permit is included at the end of this written program. The
entry permit can be thought of as a safety checklist.
Concluding Permit-Required Confined Space Operations
The entry supervisor must perform four
major tasks to conclude a permit-required confined space entry. They are:
1. Making sure that all employees are out of the confined
space.
2.
Securing the permit-required confined space. The entry supervisor will assure that the appropriate employees remove
all lockout devices, replace any safety guards that may have been removed, and will assure that the opening to the space is
left in a securely close position.
3. Assuring that appropriate personnel perform the proper
maintenance of equipment.
4. Notifying rescue and emergency services that the
entry is complete.
Review of Permit-Required Confined Space Operations
Employer will:
· Review entry operations whenever measures taken under the permit space program fail I properly protect
employees, and
·
Correct any deficiencies in the program before authorizing
subsequent entries.
The following are some examples of circumstances requiring the review of the permit-require confined space program:
· any unauthorized entry of a permit-space,
· the detection of a permit space hazard that the permit did not cover,
·
the occurrence of an injury or near-miss injury during
entry,
·
a change in the use or configuration of a permit space,
and
·
employee complaints about the effectiveness of the program.
Annual Review
The Village of Nashville will review the permit-required confined space program, annually, using the cancel permits from the previous year
entry operations. Revisions to the program will be done, if necessary, to ensure that employees participating in entry operations
are protected from the known permit space hazards.
Contractors
Employer’s Responsibilities
to Contractors
When the Village of Nashville arranges to have employees of another employer perform work that
involves permit space entry, the responsibilities
of the Village of Nashville include:
1. Informing the contractor that the workplace contains permit-required confined
spaces an that permit space entry is allowed only through compliance with a permit space program meeting the requirements
of MIOSHA.
2.
Informing the contractor of the elements, including the hazards identified and the Village of Nashville’s experience
with the space (copies of canceled permits), that make the space in question permit space.
3. Apprising the contractor of any
precautions or procedures that the Village
of Nashville has implemented for the protection
of employees in or near permit spaces where contractor personnel will be working.
4. Coordinate entry operations with the contractor if the
Village of Nashville employees and contract employees will be working in or near permit
spaces.
This includes developing and implementing procedures to coordinate entry operations when employees of
more than one contractor are working simultaneously as authorized entrants in a permit space, so that employees of one employer
do not endanger the employees of are other employer.
5. Debriefing the contractor at the conclusion of the entry
operations regarding the permit space program followed and regarding any hazards confronted or created in the permit spaces
during entry operations.
Contractor’s Responsibility to the Company
In addition to complying with the permit-required confined space requirements that
apply to all employers, each contractor whom the Village of Nashville retains to perform permit
space entry operations should:
1.
Obtain any available information regarding permit space hazards and entry operations from the Village of Nashville.
2. Coordinate
entry operations with the Village of Nashville, when both Village employees and contract employees
will be working in or near permit-required confined spaces. This includes developing and implementing procedures to coordinate
entry operations when employees more that one employer are working simultaneously as authorized entrants in a permit space,
so that employees of one employer do not endanger the employees of any other employer.
3. Inform the Village of Nashville of the permit space program that the contractor will follow and any hazards confronted or created in a permit space,
either through a debriefing or during entry operations. MIOSHA requires this exchange of information from both the Village
and the contractor.
