ENACTED BY LEGISLATURE: MAY 20, 2002

LAST AMENED AND RESTATED: December 6, 2022

CITE AS: 6 HCC § 8-15

1. Authority. See basic document (Occupational Safety and Health Program Act).

2. Purpose. This subsection of the Occupational Safety and Health Program Act contains the

requirements for practices and procedures to protect the employees of the Ho-Chunk Nation from the

hazards of entry into permit-required confined spaces.

3. Scope. Each facility of the Ho-Chunk Nation, as required by this subsection, shall develop, and

implement a written confined space program which will require each facility to do the following:

a. Identify and evaluate all confined spaces and determine if they will be classified as PermitRequired. (See Appendix A - Flow Chart.)

b. Inform employees by posting signs reading Danger Permit Required, Confined Space, Do Not

Enter or similar language at the entrance of the confined space. (See Appendix B – Sample Sign.)

c. Identify and evaluate permit-space hazards prior to allowing employee entry.

d. Test the atmospheric conditions in the permit space before entry operations and monitor the space

during entry as necessary using a direct reading instrument. The direct reading instrument must be

calibrated per manufacturer’s recommendation.

e. Perform testing in a manner that oxygen is monitored prior to or simultaneously with combustible

gases or vapors and toxic vapors and in this order if done separately.

f. Implement necessary measures to prevent unauthorized entry.

g. Establish and implement the means, procedures, and practices, such as specifying acceptable entry

conditions, isolating the permit space, providing barriers, verifying acceptable entry conditions, purging,

making inert, flushing, or ventilating the permit space in order to eliminate or control hazards necessary

for safe permit-required space entry operations.

h. Identify employee job duties.

the authorized entrants and who performs all attendant’s duties assigned in the permit-required confined

space program.

c. “Authorized Entrant” means an employee who is authorized by the supervisor to enter a permitrequired confined space.

d. “Blanking or Blinding” means the absolute closure of a pipe, line, or duct by the fastening of a

solid plate (such as a spectacle blind or a skillet blind) that completely covers the bore and that is capable

of withstanding the maximum pressure of the pipe, line, or duct with no leakage beyond the plate.

e. “Confined Space” means a space that:

(1) 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.

equipment) or event internal or external to the permit space that could endanger entrants.

h. “Engulfment” means the surrounding and effective capture of a person by liquid or finely divided

(flowable) 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.

i. “Entry” means the action by which a person(s) passes through an opening into a permit-required

confined space. Entry includes 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.

j. “Entry Permit (Permit)” means the written or printed document that is provided to allow and control

entry into a permit-required confined space and that contains the information specified in paragraph 5a of

this subsection.

k. “Entry Supervisor” means a qualified person 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 subsection. (Note: Any entry supervisor may also

serve as an attendant or as an authorized entrant, as long as that person is trained and equipped as required

by this subsection for each role he/she fills. Also, the duties of the entry supervisor may be passed from

one individual to another during the course of an entry operation.)

l. “Hazardous Atmosphere” means an atmosphere that may expose employees to the risk of death,

incapacitation, impairment of ability to self-rescue (i.e., escape unaided from a permit space), injury, or

acute illness from one or more of the following causes:

(1) Flammable gas, vapor, or mist in excess of 10% of its Lower Flammable Limit (LFL). (Note:

Entry not allowable until appropriate methods are used to lower LFL.)

(2) 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 five

(5) feet (1.52m) or less. Entry shall not be allowed until appropriate methods are used to lower LFL.)

(3) Atmospheric oxygen concentration below 19.5% or above 23.5%.

(4) Toxic atmospheric conditions with potential to be dangerous to life or health.

cutting, burning, or heating) capable of providing a source of ignition.

n. “Immediately Dangerous to Life or Health (IDLH)” means 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 space.

o. “Inerting” means the displacement of the atmosphere in a permit space by a noncombustible gas

(such as nitrogen) to such an extent that the resulting atmosphere is noncombustible. (Note: This

procedure produces an IDLH oxygen-deficient atmosphere.)

atmospheric hazards, have the potential to contain any hazard capable of causing death or serious physical

harm.

s. “Oxygen Deficient Atmosphere” means an atmosphere containing less than 19.5% oxygen by

volume.

t. “Oxygen Enriched Atmosphere” means an atmosphere containing more than 23.5% oxygen by

volume.

u. “Permit-Required Confined Space” means a “confined space” (see paragraph e, above) that has one

or more of the following characteristics:

(1) Contains or has the potential to contain a hazardous atmosphere.

(2) Has the potential for engulfing an entrant.

(3) 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.

(4) Contains any other recognized uncontrolled physical hazard.

v. “Permit-Required Confined Space Program (Permit Space Program)” means the overall program

for controlling, and where appropriate, protecting employees from permit-required space hazards and for

regulating employees’ entry into permit spaces.

w. “Permit System” means a written procedure for preparing and issuing permits for entry and for

returning the permit-required space to service following termination of entry.

x. “Prohibited Condition” means any condition in a permit-required space that is not allowed by the

permit during the period when entry is authorized.

y. “Purging” means to clean out various impurities which may create a hazardous atmosphere (i.e.,

steam heating, hot water, or using chemical solutions to remove combustible or flammable or other

aa. “Retrieval System” means equipment (including a retrieval line, full-body harness, wristlets, if

appropriate, and a lifting device or anchor) used for non-entry rescue of persons from permit-required

spaces.

bb. “Testing” means the process by which the hazards that may confront entrants of a permit-required

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.)

cc. “Ventilation” means that air supply for confined space ventilation must be from a clean source,

which will not increase the hazard in the space. Forced air ventilation shall be so directed as to avoid

recirculation of contaminated air and when possible cross ventilation with one air mover as an intake and

one as an exhaust should be established.

5. Permit System/Procedures.

a. Permit-required confined space entry will be controlled by the use of the Confined Space Entry

Permit. (See Appendix C – Confined Space Permit).

(1) The permit shall be signed by the appropriate supervisor or team leader. This signature shall

designate them as the “Entry Supervisor.”

(2) This permit shall be displayed in a conspicuous place close to the entrance of the permitrequired confined space.

(3) The duration of the permit may not exceed the time required to complete the assigned task or

job identified on the permit.

(4) Each permit shall be dated and carry an authorized duration time. Permits will be filled out on

the shift in which the work is to be performed. The checking and testing that precedes the issuing of a

permit should be as close as practicable to the time the work is to be started. The results of each

atmospheric test, initials of the tester, and the time the tests were taken shall be written on the permit. The

Entrant(s) shall be provided an opportunity to observe the testing procedure and the completion of the

permit.

(5) Every permit shall be filled out completely before entry into a permit-required confined space

is permitted.

(6) The Permit-Required Confined Space Attendant shall sign their name on the line provided on

the permit.

(7) Each Entrant shall sign the permit in the area provided signifying they understand and agree

with air testing procedures and preparation of the confined space. Signatures are also a personnel

accountability tool. Entrants will sign before every entry and after every exit from the permit-required

confined space.

(8) If conditions change due to a possible hazard, the Confined Space Entry Permit shall be

invalid. No work shall be resumed until a new permit is properly issued.

(9) Once all work has been completed inside the permit-required confined space and it is returned

to service, the Entry Supervisor shall sign off and date the permit that the job is completed. The permit

shall then be sent to the directed Department to be kept on file.

b. Confined Space Procedures. Confined Space Procedures will be indexed and maintained in each

facility and one copy posted at the confined space entrance. These procedures shall provide the following

information:

(1) The recommended cleaning and ventilating method to eliminate atmospheric hazards.

(b) All electrical/mechanical equipment to be locked out for each confined space and where

to be locked.

(3) The specific gases to be checked in each confined space.

(4) Special considerations (i.e., radioactive materials, lead seals, asbestos gaskets, combustible or

flammable material, continuous gas monitoring required and why).

(5) Special requirements when necessary for communication between entrants and Attendant.

(6) Low voltage or electrical lighting safety requirements (12-volt transformers or ground fault

interrupters (GFCI)).

(7) Rescue preparation necessary for the confined space.

(8) A drawing or sketch of the confined space may be used to help illustrate the hazards listed.

(9) Entrapment situations, if present, shall be identified. Self-closing hatches, or doors that may

be accidentally closed, should be locked open.

(10) Barriers required to protect entrants from external hazards (i.e., pedestrian, vehicle traffic).

c. Training for Confined Space Supervisor, Attendant, and Entrant.

(1) Persons assigned duties under this subsection shall be properly trained to ensure they have the

knowledge and skills necessary for the safe performance of their duties.

(2) Training documentation shall include employee name, instructor signatures, and date.

6. Responsibilities/Duties.

(4) Verify that rescue service are available and that the means for summoning them are operable.

(5) Take appropriate measures to remove unauthorized entrants.

(6) Determine whenever responsibility for a permit-required 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.

(7) Authorize the permit entry and closure by signature, date, and time, prior to entry, and when

the project is complete.

c. Attendants. Each permit-required confined space entry will have a capable person that has the

knowledge of the hazards that may be faced during entry including information on the mode, signs,

symptoms, behavioral effects, and consequences of exposure, stationed outside to serve as an attendant.

Authorized attendant duties are:

(1) Maintain communications with authorized entrants as necessary to monitor their activity and

status. (Visual communication is preferred if possible.)

(2) Alert entrants of the need to evacuate when a prohibited condition is detected inside or outside

the space.

(3) Remain at their post during entries until relieved by another authorized attendant and perform

no duties which might interfere with monitoring or protection of the entrants.

(4) Maintain an accurate record of authorized entrants in the space.

(5) Summon rescue and other emergency services as soon as authorized entrants may need

assistance to escape, and know facility communication procedures.

(6) Perform non-entry rescue techniques as appropriate as soon as practical after emergency

may face during entry, including information of mode, signs, or symptoms, and consequences of the

exposure. Authorized entrant duties are:

(1) Maintain communications with attendants as necessary to enable attendants to monitor

entrant’s status and enable attendants to alert them to evacuate if required.

(2) Alert attendant, if warning signs or symptoms are detected in their own or other entrant’s

status or they detect a prohibited condition.

(3) Evacuate space immediately if ordered to do so or an evacuation alarm is activated or they or

other entrants detect a prohibited condition.

(4) Wear personal protective equipment and retrieval equipment as provided.

(5) Harness and lifeline shall be worn by entrants unless it increases the risk of injury or would

not contribute to the rescue effort. Wristlets would be an acceptable alternative if a harness could not be

used. The free end of the retrieval line must be attached to a mechanical hand-power lifting device or

fixed point outside of the space.

(6) Prepare for non-entry rescue retrieval with a mechanical hand-powered lifting device from

vertical type entries that are more than five feet deep.

7. Securing the Confined Space.

a. The Entry Supervisor shall see that the confined space is emptied, cleaned, cooled and ventilated.

b. All electrical and mechanical equipment on the Confined Space Entry Procedure shall be secured

according to the Lock-Out/Tag-Out procedures. (See 6 HCC § 8-5.)

c. All lines (including sewer lines) connected to the confined space shall be secured in one of the

following manners (valves and blanks are to be locked or tagged per Lock-Out/Tag-Out procedures (6

HCC § 8-5).

8. Terminating Entry Permit.

a. The permit may be terminated after the following conditions are met:

(1) All repair material has been cleaned up.

(2) The Confined Space Attendant shall make sure all individuals listed on the Permit have exited

the confined space.

(3) All locks have been removed as required by Lock-Out/Tag-Out procedures.

Entry Supervisor shall ensure that no employees are still inside by whatever means necessary including,

but not limited to:

(1) Inspection of the sign-in list.

(2) Communication with the attendant.

(3) Personal visual inspection of the space.

c. The Confined Space Entry permit shall be removed at this time and the Entry Supervisor shall sign

the permit indicating the job is complete. The permit shall then be sent to the directed Department to be

retained on file for one calendar year.

d. The confined space can now be put back into operation.

9. Rescue and Emergency Service.

a. Facilities Providing Confined Space Rescue Teams.

(1) Facilities must insure that each member of the rescue service is provided with, and trained to

use properly, the personal protective equipment and rescue equipment necessary for making rescues from

permit spaces.

(2) Each member of the rescue service shall be trained to perform the assigned rescue duties.

(3) Each member of the rescue service shall also receive the training required of authorized

entrant.

(4) Each member of the rescue service shall practice making permit space rescues at least once

every 12 months, by means of simulated rescue operations in which they remove dummies or manikins or

actual persons from the actual permit spaces or from representative permit spaces. Representative permit

spaces shall, with respect to opening size, configuration, and accessibility, simulate the types of permit

spaces from which rescue is to be performed. (Note: It is not recommended to use actual persons for

hazardous vertical type rescues.)

(5) Each member of the rescue service shall be trained in basic first-aid and in cardiopulmonary

resuscitation (CPR). At least one member of the rescue service holding current certification in first aid

and CPR shall be available.

b. Facilities choosing outside rescue services shall: (See also Appendix F, 29 C.F.R. § 1910.146.)

(1) Inform the rescue services of the hazards they may confront when called on to perform rescue

at the host employer’s facility, and

(2) Provide the rescue service with access to permit spaces from which rescue may be necessary

so that the rescue service can develop appropriate rescue plans and practice rescue operations.

10. Special Situations or Alternate Methods. Certain spaces may fit the definition of a confined space

but have very limited hazard potential as evidenced by its design, use, or testing history. Each space must

be evaluated on a case by case basis to see if all aspects of a permit entry system must be followed or if

some may be safely accepted. Examples include:

a. Certain non-permit spaces may have characteristics, which if liberally interpreted could be called

confined spaces. If these spaces have no physical hazards and history shows there is no potential for

atmospheric hazards, then no mandated precautions are required. Activities and conditions in the

immediate area must be noted prior to entry to ensure the space will not be affected. A permit is not

necessary.

b. If a confined space has no potential for atmospheric hazards and all other hazards can be controlled

or eliminated without entering the space (e.g., by remote lock-out), then a Confined Space Entry Permit is

not needed. Conformance to the provisions of the Lock-Out/Tag-Out provisions of 6 HCC § 8-5 is

required.

c. A confined space classified as a permit-required confined space may be reclassified as a non-permit

confined space by the entry supervisor.

d. Additional permits such as Hot Work Permits may be necessary under special circumstances and

shall be used if required.

11. Outside Contractors.

a. Outside contractors who enter a confined space will be briefed by facility personnel on the

procedural requirements of the space to be entered.

b. Facility personnel will ensure the safe start of the entry by making initial air tests, supervising

lockouts by contractors, and confirming the availability of a rescue team. This will be documented on a

facility permit and will be signed at the bottom left hand corner in the space provided for the contractor’s

signature. The contractor will then provide their own permit.

c. The contractor will provide an entry supervisor and will be responsible for all subsequent air tests,

attendant requirements, and job safety.

d. Contractors will furnish all required safety equipment, hardware, and permits required for their

safety.

12. Administrative and Enforcement. See Section 12 of the Occupational Safety and Health Program

Act.
