OBJECTIVE
Many workplaces contain spaces that are considered "confined" due to configurations that hinder
the activities of employees entering, working in, or exiting the spaces. OSHA defines a confined
space as any space that is large enough and so configured that an employee can bodily enter and
perform assigned work, has a restricted means of entry or exit, and is not designed for continuous
employee occupancy. All of these criteria must be met for a space to be classified as confined.
Examples of confined spaces include tanks, pits, certain tunnels, utility vaults, and boilers.
In addition, there are many instances where employees who work in confined spaces face
increased risk of exposure to serious hazards. In some cases, confinement poses entrapment
hazards. In other cases, confined space work keeps employees closer to hazards, such as
asphyxiating atmospheres or the moving parts of machinery. OSHA uses the term "permitrequired confined space" to describe those spaces that meet both the definition of confined space
and pose health or safety hazards.
The Confined Space Program should be used in conjunction with other EHS safe work practices
including: use of Personal Protective Equipment (PPE), safe handling of hazardous materials and
isolation of energy sources (Lock-out/Tag-out). It is the objective of this Program to protect
WCMC staff and outside contractors from the health and safety risks associated with working in
confined spaces.

TYPES OF CONFINED SPACES
Many spaces on the WCMC campus can be considered "confined" due to internal configurations
that hinder the activities of employees entering, working in, or exiting the spaces. OSHA defines
a confined space as, “any space that is large enough and so configured that an employee can
bodily enter and perform assigned work, has a restricted means of entry or exit, and is not
designed for continuous employee occupancy”. Confined spaces can be divided into two
categories: Non Permit-Required and Permit-Required Confined Spaces.

NON PERMIT-REQUIRED CONFINED SPACES
A Non Permit Required Confined Space is:
 large enough for an employee to enter fully and perform assigned work;
 not designed for continuous occupancy by the employee; and
 has limited or restricted means of entry or exit.
Some examples of confined spaces are: shafts, crawlspaces, air handling units, vaults,
and tanks.
6.2
INTRODUCTION OF HAZARDS INTO NON PERMIT-REQUIRED CONFINED
SPACES
The introduction of certain hazards may change the atmospheric conditions of a non
permit-required confined space and required additional entry procedures. Some
specific hazards that may require alternate entry procedures are:
 Hotwork (welding, torch cutting, brazing)
 Chemicals (coatings, paints, ect.)
 Compressed Gasses
EHS must be contacted to conduct an evaluation of a confined space when hazards
are to be introduced.
6.3
PERMIT-REQUIRED CONFINED SPACES
A Permit-Required Confined Space also has one or more of the following
characteristics:
 contains or has the potential to contain a hazardous atmosphere;
 contains a material with the potential to engulf someone who enters the space;
 has an internal configuration that might cause an entrant to be trapped or
asphyxiated by inwardly converging walls or by a floor that slopes downward and
tapers to a smaller cross section; and/or
 contains any other recognized serious safety or health hazards.
Examples of Permit-Required Confined Spaces include the acid neutralization tanks
in the basement of the 1300 York Avenue complex and the S Building. Refer to
Appendix A for a full list of Permit-Required Confined Spaces at WCMC.
7.0
IDENTIFICATION AND WARNING
EHS has identified, classified, and recorded the location of confined spaces at WCMC. A list of
Confined and Permit-Required Confined Spaces is available in Appendix A and is kept on file in
the EHS office. Contractors working at WCMC should be provided this manual by Project
Managers, which contains a list of confined spaces at the College. It is the responsibility of
contractors working at WCMC to read and ensure all work is performed in compliance with this
manual and 29 CFR 1910.146. If a location encountered on campus appears to meet the
definition of a confined space, and is not posted as such nor appear in Appendix A, contact EHS.

General Safety
Permit-Required Confined Spaces located inside buildings are identified and posted with
appropriate signs to guard against the entry of unauthorized individuals. Where possible, PermitRequired Confined Spaces will be secured to prevent unauthorized entry. Permit-Required
Confined Space signs at WCMC must state, “Danger Confined Space Enter by Permit Only” (see
Figure 7.1 below).
Figure 7.1
8.0
UNAUTHORIZED ENTRY
Unauthorized entry into Permit-Required Confined Spaces will be prevented using a
combination of signs and placards, training, and physical barriers to bar or lock the entrance or
entrance cover. WCMC employees must not enter Permit-Required Confined Spaces under any
circumstances. All entry into WCMC Permit-Required Confined Spaces must be conducted by a
properly trained contractor and coordinated with EHS.
9.0 NON PERMIT-REQUIRED CONFINED SPACE PROCEDURES
All individuals who enter a non-permit required confined space should be aware of the specific
hazards that are posed in the space and take the appropriate safety precautions to protect
themselves.
10.0 INTRODUCING HAZARDS INTO NON PERMIT-REQUIRED CONFINED SPACE
A variety of tasks and work activities have the potential to create additional hazards in Non
Permit-Required Confined Spaces. If additional hazards will be introduced into a space, PermitRequired Confined Space or additional entry procedures may be required. All work that will
introduce additional hazards into a confined space must first be coordinated and evaluated by
EHS. This includes all hotwork and/or work involving the use of chemicals which have
inhalation hazards associated with them. These work tasks may create a potentially hazardous
atmosphere and necessitate Permit-Required or modified confined space procedures. EHS will
conduct an assessment of the space, make recommendations for personal protective equipment,
engineering controls, and conduct air monitoring for all WCMC work activities that may
introduce additional hazards into confined spaces.

Contractors conducting work in and introducing hazards into Non Permit-Required Confined
Spaces must also have these spaces evaluated by EHS. The WCMC Project Manager or
representative from the contractor should contact EHS to have the space evaluated and the entry
coordinated. The contractor must the follow all entry requirements. Any required atmospheric
monitoring, addition PPE, or equipment must be provided by the contractor.
11.0 PERMIT-REQUIRED CONFINED SPACE PROCEDURES
Due to the extensive training, equipment, and personnel requirements, Permit-Required Confined
Spaces will not be entered by WCMC employees. Entries into the permit-required confined
spaces at WCMC will only be conducted by authorized contractors.
Contractors who are required to enter WCMC permit-required confined spaces must submit their
written Confined Space policies, training certificates, and Material Safety Data Sheets (MSDS’s)
to EHS at least seven days prior to the commencement of work. EHS will apprise the contractor
of any hazards identified, experience with the space, and what classifies it as a permit-required
confined space.
EHS will coordinate entry operations with the contractor if WCMC personnel or other contractor
personnel are working in or near the confined space being entered. If employees of more than
one employer are working simultaneously as authorized entrants in a confined space, procedures
to coordinate entry operations must be developed and implemented.
Contractors entering WCMC Permit-Required Confined Spaces will follow procedure below.
11.1 ENTRY SUPERVISOR / PROJECT MANAGER





Identify the staff members who will enter the confined space and determine
what role they will have while working in the space. Typical roles may include,
but are not limited to, the following:
o Authorized Entrant(s)
o Authorized Attendant(s)
o Rescue / Emergency Services Team
Receive training in the same procedures as authorized entrants and attendant.
Develop procedures prior to the commencement of confined space operations
for:
o Rescuing entrants from permit-required confined spaces.
o Providing necessary emergency services for rescue.
o Summoning rescue and emergency services.
o Preventing unauthorized personnel from attempting a rescue.
o PPE required for safe entry into space.
Obtain a Confined Space Entry Permit from EHS before entry into any permitrequired confined space (see Appendix B).

clean air and re-sample. If the meter reaches levels again, review the space,
implement controls and retest.
Continuous monitoring must be conducted in the space for the duration of the
permit entry.
Readings should be recorded every 15 minutes on the entry permit.
Monitoring for hazardous vapors, dusts, mists and fumes may be necessary to
determine safe exposure levels and the selection of personal protective equipment.
The confined space meters do not detect substance specific hazards from
processes or operations.
13.0 VENTILATION
Forced air mechanical ventilation shall be used to control atmospheric hazards within a confined
space. Caution: Forced air ventilation shall only be used to control a hazard; use of ventilation
does not constitute elimination of hazard.








Select the blower based on the volume of the space, number of elbows in the flex hose
and the length of hose and not just on the CFM on the fan.
Blower must be capable of maintaining a least 20 air changes per hour for a ventilation
rate.
Purge the space for at least 10 minutes prior to entry. Longer purge times may be
necessary for smaller blowers or larger spaces.
The forced air ventilation shall be directed to ventilate the immediate areas where an
employee is or will be present within the space and shall continue until all employees
have left the space.
The air supply for the forced air ventilation shall be from a clean source and may not
increase the hazards in the space.
Place supply air hose near area of work and never lower than 25% of the total height of
the space.
Supply and local exhaust ventilation is necessary for hotwork in confined spaces.
Locate blower away from car exhaust or other contaminant sources.

General Safety
Dangerous Air Contamination: An atmosphere capable of causing death, injury, acute illness,
or disablement due to the presence of flammable, explosive, toxic, or incapacitating substances.
Enclosed space: Spaces that do not meet the definition of a confined space, but may require
precautionary measures upon entering. Examples of enclosed spaces are crawl spaces and service
tunnels with existing general ventilation.
Emergency: Any occurrence (including any failure of hazard control or monitoring equipment)
or event internal or external to the permit space that could endanger entrants.
Engulfment: The surrounding and effective capture of a person by a liquid or finely divided
(fluidic) solid substance that can be aspirated to cause death by filling or plugging the respiratory
system or that can exert enough force on the body to cause death by strangulation, constriction,
or crushing.
Entry: The action by which a person passes through an opening into a permit-required confined
space. Entry includes ensuing work activities in that space and is considered to have occurred as
soon as any part of the entrant's body breaks the plane of an opening into the space.
Entry Permit: The written or printed document that is provided by the employer to allow and
control entry into a permit space. A permit (Attachment B) must be completely filled out by
EHS prior to entering the space. Employees entering confined spaces must have signature
approval from their supervisor on the confined space entry permit prior to entry. No permit shall
be valid for more than 24 hours after the time of issue by the supervisor.
Entry Supervisor: The person (such as the employer, foreman, or crew chief) responsible for
determining if acceptable entry conditions are present at a permit space where entry is planned,
for authorizing entry and overseeing entry operations, and for terminating entry as required by
this section. NOTE: An entry supervisor also may serve as an attendant or as an authorized
entrant, as long as that person is trained and equipped as required by this section for each role he
or she fills. Also, the duties of entry supervisor may be passed from one individual to another
during the course of an entry operation.
Hazardous Atmosphere: An atmosphere that may expose employees to the risk of death,
incapacitation, impairment of ability to self-rescue (that is, escape unaided from a permitrequired confined space), injury, or acute illness from one or more of the following causes:
 Atmospheric oxygen concentration below 19.5 percent or above 23.5 percent
 Flammable gas, vapor, or mist in excess of 10 percent of its lower flammable limit (LFL)
 Airborne combustible dust at a concentration that meets or exceeds its LFL. Note: This
concentration may be approximated as a condition in which the dust obscures vision at a
distance of 5 feet (1.52 m) or less.
 Atmospheric concentration of any substance for which a dose or a permissible exposure
limit is published in Subpart G, Occupational Health and Environmental Control, or in
Subpart Z, Toxic and Hazardous Substances, of 29 CFR1910 and which could result in
employee exposure in excess of its dose or permissible exposure limit NOTE: An
atmospheric concentration of any substance that is not capable of causing death,
incapacitation, or impairment of ability to self-rescue, injury, or acute illness due to its
health effects is not covered by this provision.
 Any other atmospheric condition that is immediately dangerous to life or health.

Introduced Hazard Non Permit-Required Confined Space: A space that meets all traditional
definitions of a confined space but has an introduced hazard through work. Hotwork or
introducing chemicals into a space will cause a Non Permit Required Confined Space into a
hazardous space. Ventilation and Atmospheric monitoring must be conducted to mitigate any
hazardous atmosphere before the space can be entered.
Immediately dangerous to life or health (IDLH): Any condition that poses an immediate or
delayed threat to life or that would cause irreversible adverse health effects or that would
interfere with an individual's ability to escape unaided from a permit-required confined space.
Non-permit confined space: A confined space that does not contain or, with respect to
atmospheric hazards, have the potential to contain any hazard capable of causing death or serious
physical harm.
Permit-Required Confined Space: Confined space that has one or more of the following
characteristics:
 Contains or has a potential to contain a hazardous atmosphere
 Contains a material that has the potential for engulfing an entrant
 Has an internal configuration such that an entrant could be trapped or asphyxiated by
inwardly converging walls or by a floor which slopes downward and tapers to a smaller
cross-section
 Contains any other recognized serious safety or health hazard
Permit System: The employer's written procedure for preparing and issuing permits for entry
and for returning the permit space to service following termination of entry.
Prohibited Condition: Any condition in a permit space that is not allowed by the permit during
the period when entry is authorized.
Rescue Service: The personnel designated to rescue employees from permit spaces.
Retrieval System: The equipment (including a retrieval line, chest or full-body harness,
wristlets, if appropriate, and a lifting device or anchor) used for non-entry rescue of persons from
permit spaces.
Testing: The process by which the hazards that may confront entrants of a permit space are
identified and evaluated. Testing includes specifying the tests that are to be performed in the
permit space. NOTE: Testing enables employers both to devise and implement adequate control
measures for the protection of authorized entrants and to determine if acceptable entry conditions
are present immediately prior to, and during, entry.
