BROWN COUNTY
CONFINED SPACE PROGRAM
Purpose of this program:
This program is intended to comply with OSHA 29 CFR 1910.146
This program is intended to protect workers that may enter a confined space. Employees
will be made aware of the hazards of a confined space, how to enter a confined space
safely and what to do in case of an emergency.
Identification of Confined Spaces:
Confined Space. A space that:
Is large enough and so configured that an employee can bodily enter
and perform assigned work; and
(2) Has limited or restricted means for entry or exit (for example, tanks,
vessels, silos, storage bins, hoppers, vaults, and pits are spaces that
may have limited means of entry.); and
(3) Is not designed for continuous employee occupancy.
(1)
NOTE: Confined spaces are labeled and shall not be entered without the appropriate
permit. If there is an unlabeled space that you feel qualifies as a confined space, notify
your supervisor and the Safety Coordinator before entering.
Classification of Confined Spaces:
Confined spaces are classified on the basis of measurements of the oxygen content,
flammability, toxicity, physical hazards, and mechanical hazards. All personnel will
assume a confined space is permit-required until proven otherwise by testing and
inspection.
A Permit-Required Confined Space:
1. contains or has the potent to contain a hazardous atmosphere or
2. contains a material that has the potential for engulfing or entrapping an entrant
or
3. has an internal configuration that might cause an entrant to be trapped or
asphyxiated by inwardly converging walls or by converging walls or by a floor
that slopes downward and tapers to a smaller cross section, and/or
4. contains any other recognized serious safety or health hazards.
A Non-Permit Confined Space: means 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.

1) Scope
This program contains requirements for employees of the Facility Management Department
while working for the department in their normal work duties. This program does not cover:
Immediately Dangerous to Life or Health (IDLH) situations: IDLH spaces will be
handled by someone other than the Facility Management staff. We value our
employees and do not believe in putting them at unnecessary risk, thus, these
situations will be handled by others with more experience in entering an IDLH space.
NOTE: Only for rescue situations may a Facility Management employee enter an
IDLH space if, and only if, they have the resources to protect themselves and are
properly trained for rescue.
Outside contractors: Contractors are covered in the Confined Space Program. (See
section 6.)
Spaces outside of the realm of the Facility Management department: These spaces will be
covered by other departments and shall not be entered before contacting the Safety
Coordinator.

Entry Supervisor: Duties of entry supervisors. The employer shall ensure that each entry
supervisor:
1. Knows the hazards that may be faced during entry, including information on the
mode, signs or symptoms, and consequences of the exposure;
2. Verifies, by checking that the appropriate entries have been made on the permit,
that all tests specified by the permit have been conducted and that all procedures
and equipment specified by the permit are in place before endorsing the permit
and allowing entry to begin;

6. Determines, whenever responsibility for a permit space entry operation is
transferred and at intervals dictated by the hazards and operations performed
within the space, that entry operations remain consistent with terms of the entry
permit and that acceptable entry conditions are maintained.
Confined Space Attendants: The definition of Attendant is an individual stationed outside
a Permit Space who monitors an authorized Entrant and who performs all Attendant’s
duties assigned in our Confined Space program:
1. Knows the hazards that may be faced during entry, including information on the
mode, signs or symptoms, and consequences of the exposure;
2. Is aware of possible behavioral effects of hazard exposure in authorized entrants;
3.
Continuously maintains an accurate count of authorized entrants in the permit
space and ensures that the means used to identify authorized entrants who are in
the permit space;
4. Remains outside the permit space during entry operations until relieved by another
attendant;
5. Communicates with authorized entrants as necessary to monitor entrant status and
to alert entrants of the need to evacuate the space;

16. Performs non-entry rescues as specified by the employer's rescue procedure; and
17. Performs no duties that might interfere with the attendant's primary duty to
monitor and protect the authorized entrants.
Confined Space Entrants: (Entrants) are employees who we authorize to enter a Permit Space.
1. Know the hazards that may be faced during entry, including information on the
mode, signs or symptoms, and consequences of the exposure;
2. Properly use equipment as required;
3. Communicate with the attendant as necessary to enable the attendant to monitor
entrant status and to enable the attendant to alert entrants of the need to evacuate
the space;
Alert the attendant whenever:
4. The entrant recognizes any warning sign or symptom of exposure to a dangerous
situation, or
5. The entrant detects a prohibited condition; and
Exit from the permit space as quickly as possible whenever:
6. An order to evacuate is given by the attendant or the entry supervisor,
7. The entrant recognizes any warning sign or symptom of exposure to a dangerous
situation,
8. The entrant detects a prohibited condition, or
9. An evacuation alarm is activated.
3) Testing:
Confined Space Tester and Monitor: The person designated to conduct tests of confined
space atmospheric conditions must be trained in the operation and care of the specific
testing equipment to be used.
Calibration:
All equipment will be calibrated prior to use by either the Safety
Coordinator or a member of the CSPT. The user will field check equipment
according to the manufactures instructions immediately before testing the confined
space.
Equipment: All equipment used in confined space shall be approved for Class 1,
Division 1 use. Only direct reading equipment with current calibration will be used.
Atmospheric Monitoring: Many operations, due to the potential to generate hazardous
conditions, may require atmospheric monitoring as work progresses. No single rule
can be established. The supervisor in charge of entry, shall establish frequency and
type of tests for atmosphere and shall enter these requirements on the entry permits.
Revised 11/2010

Continuous monitoring of O2, LEL, & Toxicity should be considered for all permit
required operations. The entry supervisor shall evaluate the following types of
operations for continuos atmospheric monitoring:
1) Work which has the potential of generating hazardous concentrations of toxic
materials.
2) Application of paint, epoxies, etc. which may involve toxic or flammable
vapors.
3) Cleaning operations, sludge removal, etc. that may produce a hazardous
environment.
Testing sequence: Oxygen content, flammable hazard, toxic material. (NOTE: this is an
OSHA requirement; however, our gas tester tests four gasses simultaneously.)
Revised 11/2010

4) Emergency and Rescue Procedures:
If self rescue or non-entry rescue can not be performed, contact rescue personnel
immediately by dialing 911. Also call the entry supervisor immediately for assistance
in the rescue operation.
Self Rescue: Employees are trained to exit from the confined space as rapidly as possible
without help, the entrant must also know toxic effects or symptoms of exposure to
the anticipated hazard, the entrant must also be able to relay an alarm to the attendant
and to attempt self-rescue immediately.
Rescuers may enter a space if the space does not contain a hazardous atmosphere (i.e. the
employee tripped and broke his ankle and needs assistance getting out). The attendant
must first wait for the entry supervisor before entering the space.
When an employee collapses or is non-respondent, all rescuers should consider the space
to be IDLH and take the appropriate precautions. Call 911. Note: this is the only
situation that it is acceptable to enter a known IDLH space, IF you have the
appropriate PPE, AND you can enter the space without putting yourself in
unnecessary danger, AND you have been trained for this type of rescue.
Non-Entry Rescue: This is the preferred method of rescue.
1) Entrants must wear a chest or full body harness with a retrieval line attached to the
center of their back (near shoulder level) or above the Entrant’s head.
2) Wristlets can be used instead of a harness if using the harness is not feasible or
creates a greater hazard than if wristlets are used.
3) The other end of the retrieval line must be attached to a fixed point or mechanical
device outside the Permit Space so that rescue can begin as soon as needed.
4) A mechanical device (such as a winch) must be available if entrants are working
in a vertical space that is more than five feet deep.
5) There are exceptions to the requirement, retrieval equipment does not have to be
used if it would increase the overall risk or injury, or increase the chance of an
accident to entrants working in confine spaces, or if it would not contribute to the
ability to rescue entrants.
Emergency Rescue Information: OSHA wants to make sure that medical personnel
treating an entrant who has been injured in a confined space have as much helpful
information as possible. OSHA requires that if an injured entrant is exposed to a
substance for which you are required to keep a Material Safety Data Sheet (MSDS) or
other similar written information on site, that information must be made available to
the medical facility treating the exposed entrant.
Revised 11/2010

5) Non Permit Confined Spaces: These confined spaces are not considered hazardous and
have no potential to become hazardous. Entries into non-permit confined spaces are allowed
without an entry permit, but it is required that the entrant wear a “Four Gas Detector” and to
evacuate if the alarm goes off.
Welding, Cutting, and Brazing: Hot Permits must be completed before hot work is
performed in confined space. Note: A Non-Permit Required Confined Space will
become a Permit Required Confined Space when hot work is performed.
1. Compressed gas cylinders or gas manifolds are prohibited in a confined space.
2. Gas supplies will be turned off at the cylinder.
3. Electric ARC units are prohibited in a confined space.
6) Contractors
All contractors will be notified of hazards concerning the entrance of particular confined
spaces. This notification will be done in writing by the Department Manager or Safety
Coordinator. All contractors are to have their own Confined Space program prior to
undertaking a contract that entails the entrance of confined spaces.
