I. Program Goals and Objectives This program establishes a process to protect employees from the hazards associated with the entry into confined spaces and provides guidance for the safe access, entry, and egress of confined spaces.

II. Scope and Application This program applies to all Northwestern employees and contractors working in confined spaces.

A. Definition Confined spaces are defined as areas that:

1. Are large enough for an employee to enter and perform work 2. Have limited or restricted means for entry or exit, and 3. Are not designed for continuous occupancy

Examples of confined spaces at Northwestern are sewers, manholes, tunnels, tanks, boilers, transformers, pipes, excavations, elevator pits, vaults, and ducts.

For the purpose of this program, there are two classifications of confined spaces: • Non-permit required confined space • Permit required confined space

B. Evaluation Conduct assessments to determine whether a confined space is classified as a non-permit required confined space or a permit required confined space. When there are changes in the use or configuration of a non-permit confined space, or when certain operations (e.g. welding, steam lines, chemicals) that might introduce or create new hazards to entrants, the confined space shall be re-evaluated prior to entry. If necessary, the space will be reclassified as a permit-required confined space. Refer to Appendix 1 for assessment instructions and Appendix 2 for the assessment form.

III. Responsibilities C. Risk Management Services

i. Review, audit, and revise this program and permit process annually or anytime deemed necessary.

ii. In collaboration with Facilities Management, assess new and existing confined spaces.

iii. Provide guidance and technical assistance as needed.

D. Facilities Management Operations

i. Prior to entry into a confined spaces, conduct assessments to determine hazards and if a permit is required.


ii. Communicate all findings from confined space assessments with all employees or contractors involved or affected.

iii. Department chief, supervisor, or designee to approve entry into permit required confined spaces.

iv. Ensure employees are fully informed, authorized, and trained in confined space entry requirements and procedures as outlined in this program.

v. Prevent unauthorized entry into permit required confined spaces through training, signage, and security measures.

vi. Monitor employees need for additional or refresher training, based upon assigned duties, changes in confined spaces, or changes to this program.

vii. Collaborate with Risk Management Services to assure that contractor’s Confined Space Program and permit process is compliant with regulatory requirements.

E. Project Managers i. Inform contractors of work that involves any confined space entry and provide

assessments for those spaces. ii. Collaborate with Facilities Management when energy shutdowns or lifesaving

impairments are necessary. iii. Collaborate with Risk Management Services to assure that contractor’s Confined

Space Program and permit process is compliant with regulatory requirements. iv. Inform and provide contractors with the Northwestern Confined Space Program

and specific procedures developed for confined space entries.

F. Authorized Entry Supervisors, Attendants, and Entrants i. Successfully complete confined space entry training.

ii. Conduct assigned tasks in a safe manner at all times. iii. Wear appropriate personal protective equipment. iv. Report any injuries, illnesses, questions, or any unsafe working conditions to

Departmental Supervisor.

G. Contractors i. Provide a copy of a site specific/project specific confined spaced program to

Northwestern Project Managers and Risk Management Services; this program must meet or exceed the minimum requirements set forth in this program in addition to the Confined Spaces in Construction regulations if applicable.

ii. Obtain copies of all necessary confined space assessments and coordinate all confined space entries with Facilities Management; this includes entry when both Northwestern personnel and contractor personnel will be working in or near confined spaces.

iii. Ensure that employees are properly trained in confined space entries. iv. Provide the necessary equipment, PPE, personnel, and resources necessary for

safe entry into confined spaces, including air-monitoring equipment. v. Post permits at confined space entry sites for the duration of the entry.


vi. Inform Northwestern Project Manager of any hazards confronted or created in the confined space.

vii. Develop rescue procedures specific to the space(s) entered. Effective means of rescue must be in place by use of a non-entry retrieval system, such as a tripod, winch, lifeline, and body harness. If a non-entry retrieval system will be ineffective for entrant rescue, a rescue team must be on standby outside the space with all necessary tools and equipment to perform an entry rescue, if needed.

viii. In the event of an emergency requiring confined space rescue, the authorized entry supervisor or attendant will immediately notify emergency services as indicated in Appendix 3.

IV. Training A. Responsibility Departments are responsible for ensuring employees are properly trained and proficient in the duties required for confined space entry. Additional training is required when procedures are updated or a new hazard exists.

B. Requirements Confined space entry training is required:

i. Before an employee is initially assigned a task involving a confined space as a supervisor, entrant, or attendant

ii. Whenever there is a change in a confined space that presents hazards(s) to which the employee has not been previously trained

iii. If there are observed inadequacies in an employee’s knowledge or execution of confined space procedures

C. Refresher Training Confined space refresher training is required every 3 years for all employees involved in confined space operations.

V. Signage A. Requirements For all permit-required confined spaces, post appropriate signage at the entry portal, hatch, cover, or equally effective location. B. Outdoor manhole covers and hatches

i. Outdoor manhole covers and hatches for permit-required confined spaces are not required to have signage, as long as access points are kept locked or require special tools, such as a cro-bar or pry-bar, to open.

ii. Number all access points to permit-required confined spaces that do not have posted signage in a conspicuous manner, such as with paint, tag, or other effective means, for identification purposes.


VI. Communication Departments and contractors must ensure that two-way communication is available during all permit-required confined space entries and are responsible for ensuring adequate communication:

i. Between those inside the confined space ii. Between those inside the confined space and those outside

iii. To summon emergency responders in the event of an emergency

Examples of acceptable forms of communication are: i. UHF portable radio

ii. Cellular phone iii. Verbal iv. Tapping v. Fixed telephone, if available

vi. Visual (e.g.: hand signals) vii. Tugs on a lifeline

Cellular service and UHF radio coverage may be limited in certain confined spaces at Northwestern. Effective communication is required for all permit-required confined space entries.

VII. Air Monitoring Instrumentation Departments are responsible for maintaining, calibrating, and operating all air monitoring equipment according to the manufacturer’s instructions.

i. Prior to performing air monitoring for permit-required confined space entry, perform a bump test or full calibration in accordance with the manufacturer’s instructions using the appropriate test gas.

ii. Adjust any instrument that fails a bump test by a full calibration before further use. iii. Calibration of air monitoring equipment must be performed monthly and documented.

Atmospheric conditions must remain within the following limits while workers are in the space:

i. Oxygen: 19.5-23.5% ii. Lower Explosive Limit (LEL): < 10%

iii. Carbon Monoxide (CO): < 35 PPM (Parts per Million) iv. Hydrogen Sulfide (H2S): < 10 PPM (Parts per Million)

VIII. Rescue A. Rescue Procedures

i. Rescue procedures are required for all permit-required confined space entries. ii. If an entrant requires rescue from a confined space, the Entry Supervisor or

Attendant shall always notify the Department of Safety and Security (formerly Northwestern University Police) immediately.


B. Rescue Methods There are two types of rescue: entry and non-entry.

i. Trained rescue professionals can only perform entry rescue. ii. Trained attendants and entry supervisors may perform non-entry rescue with the

use of a retrieval system.

C. Rescue Method Selection i. Retrieval systems, such as tripods, shall be set-up and used whenever an employee

enters a permit-required confined space to facilitate non-entry rescue, if needed. ii. Retrieval systems shall include a chest or full body harness, retrieval line, and a

mechanical retrieval device (if the vertical space is over 5 feet deep). iii. The retrieval system is not required if the equipment would increase the overall risk

of entry or would not contribute to the rescue of the entrant. iv. If non-entry retrieval equipment will not be effective, a means of entry rescue must

be in place, such as a standby rescue team with SCBA’s. Northwestern employees are not permitted to enter a confined space to perform a rescue under any circumstances.

IX. Reclassification and Alternate Entry Procedures A. Reclassification

i. Temporary entry into a permit-required confined space without the use of a permit may be allowed, if certain criteria are met.

ii. If no actual or potential atmospheric hazards are present, and all other serious hazards are eliminated, the space may be temporarily entered using the reclassification form in Appendix 5.

iii. Entry operations are immediately canceled when the work is completed, a condition that is not allowed under the form arises, or after 8 hours. Re-entry into the space requires a permit or new reclassification form.

iv. The reclassification form may not be used at the following locations: a. Evanston campus lift stations b. Evanston Central Utility Plant c. Chicago Utility Plant

B. Alternate Entry Procedures Risk Management Services has determined there are no permit-required confined spaces at Northwestern that meet the criteria for using alternate entry procedures. However, in the rare circumstance that a space becomes eligible for using alternate entry procedures, written approval and authorization is required from Risk Management Services and the Entry Supervisor. Refer to Appendix 6 for the alternate entry procedures form.


X. Recordkeeping Departments are responsible for maintaining confined space records.

i. Entry permits and forms shall be retained for at least three years. ii. Air monitoring instrument records (bump tests, calibrations, and service repairs) must

be retained for at least three years. Electronic means, such as instrument software, may be used to record this information in lieu of paper logs, if available. Refer to Appendix 7 for an example of a bump test log sheet.

iii. Facilities Management shall be responsible for maintaining the confined space assessments, either electronically or in a hard copy format. Assessments shall be kept readily available as long as they are valid and accurate. Any new assessments or changes to existing assessments shall be included as necessary.

iv. Departments are responsible for maintaining employee training records and must be kept for a minimum of three years; records must include employees names, trainers signatures or initials, and dates of training.

XI. Regulatory Authority Northwestern and contractors will comply with the Occupational Health and Safety Administration’s (OSHA) standards and any other applicable codes and standards.

Appendix 1 Confined Space Assessment Instructions These instructions address how to conduct a Confined Space Assessment. The purpose is to determine if a space is non-permit required space or a permit required confined space. This assessment does not replace the required Confined Space Permit, but provides guidance for the safe entry into Confined Spaces at Northwestern. Take into account the work that will be performed and decide if the work itself will create a hazard.

Step 1: Confined Space Determination: Section A Determine if the space is a Confined Space. Confined spaces are defined as areas that:

1. Are large enough for an employee to enter and perform work 2. Have limited or restricted means for entry or exit, and 3. Are not designed for continuous occupancy

If ‘NO’ is answered to any question in Section A, no further assessment is required as the area would not qualify as a Confined Space.

Step 2: Permit-Required Determination: Section B Determine if the Confined Space qualifies as a Permit-Required Space. Take into account the work that will be performed and decide if the work itself will create a hazard. Hazard considerations in this section include: atmospheric, engulfment, work space configuration, entry and egress, ventilation requirements, and lifeline considerations.

Step 3: Alternate Entry Determination: Section C Determine if alternate entry procedures may be used in the confined space. Information from Section B will be used to help determine if alternate entries are appropriate.

Step 4: Final Determination: Section D Determine whether the work is Non-Permit Required, a Permit-Required Confined Space, or whether Alternate Entry Procedures can be used. If ‘YES’ was marked for any hazards in section B items 2-4, then the space is a Permit-Required Confined Space.

If the work being conducted is considered a Permit-Required Confined Space, proceed to Appendix 4, Confined Space Entry Permit.

Confined Space Assessment

Date of Assessment: Conducted By:

Building: Space Location:

Type of Space: Purpose of Entry:

Section A: Confined Space Determination Yes No

1. The space is large enough and is so configured that an employee can bodily enter and performassigned work.

2. The space has limited or restricted means of entry or exit. (i.e. tanks, vaults, vessels, silos,storage bins, hoppers, pits, diked areas)

3. The space is not designed for continuous employee occupancy.

If you answered YES to all three of the questions above, then the space is considered a confined space. Proceed to Section B.

If you answered NO to any one of the three questions above, the space is not a confined space, check the box below and proceed no further.

The area does not qualify as a “confined space.”

Section B: Permit-Required Confined Space Determination: Yes No

1. Does the space have or have the potential for a hazardous atmosphere?

If YES, please check the hazards(s) below:

a. Oxygen Deficient (O2 concentration below 19.5%)

b. Oxygen Enriched (O2 concentration at or above 23.5%)

c. Explosive Gas/Vapor

d. H2S (Hydrogen Sulfide)

b. Forced Positive

c. Forced Negative

7. Will the entrant need to detach from the lifeline requiring rescue on site?

Section C. Alternate Entry Procedure Determination Yes No

1. If any items 2-4 of Section B were marked YES, then alternate entry procedures are NOT allowed for the space.

2. Is the only hazard an actual or potential hazardous atmosphere?

3. If yes, will ventilation alone maintain safe conditions?

If YES was marked in item 2 above, the space may use alternate entry procedures. If at any time the space changes and other hazards are present, it is automatically a permit-required confined space again.

Section D. Final Determination

If alternate entry procedures (section C) are not allowed and if “yes” was marked for any hazards in section B items 2-4, then a permit is required.

1. Non-Permit Confined Space

2. Permit-Required Confined Space

3. Alternate Entry Procedures Allowed

NOTE: Careful consideration must be given to spaces that have limited radio or cellular phone coverage. Effective communication is required for all permit required confined space operations.

Yes No



Appendix 3 General Confined Space Entry Guidelines A. Pre-Entry Guidelines

i. Notify the Department of Safety and Security (formerly Northwestern University Police)prior to entry into a Permit-Required Confined Space. This information should be notedon the entry permit.

Evanston Campus: (847) 491-3254 Chicago Campus: (312) 503-3456

ii. Confined spaces may be immediately dangerous to life or health (IDLH);iii. Conduct a confined space assessment to evaluate work activities that will reclassify a

confined spaced as a permit-required confined space; refer to Appendix 1 for instructionand Appendix 2 for an example of the form;

iv. Conduct pre-work briefings describing work conditions, hazards, responsibilities,assigned duties, communication, and rescue/emergency services procedures;

v. Test all air monitoring equipment before each entry into a confined space in accordancewith the manufacturer’s instructions; calibrate if necessary;

vi. Retain and record all air monitoring test/calibration data with the entry permit;vii. Entry Supervisor will assure air monitoring has been conducted within 15 minutes prior

to entering any permit-required confined space;viii. Atmospheric testing must check for oxygen levels (must be between 19.5% and 23.5%),

explosive gas levels (must be lower than 10% of the lower explosive limit), carbonmonoxide (must be less than 35 ppm) and hydrogen sulfide (must be less than 10ppm) in that order;

ix. No employee may enter a confined space until all identified hazards are eliminated orcontrolled, and acceptable entry conditions have been established;

x. If the minimum oxygen content of 19.5 percent cannot be maintained by forced airventilation, and the environment is oxygen deficient, consult with FacilitiesManagement Operations and Risk Management Services;

xi. When continuous forced air ventilation is used to eliminate a hazardous atmosphere, airshould be taken from a clean source and should be continued until all employees haveleft the space. This method shall not be used if asbestos is present in the space;

xii. Complete and post the authorized confined space permit at the entry portal, or by anyother equally effective, conspicuous manner prior to beginning work.

B. Entry Guidelines i. Only trained and authorized employees may enter a confined space or act as an

attendant; measures shall be in place to prevent unauthorized entries;ii. During permit-required confined space entries, an attendant must be present at all

times; the attendant shall not perform any other tasks that could potentially interferewith his/her abilities to provide any/all support necessary to the entrant(s);

iii. Smoking is prohibited in confined spaces and near the entrance/exit area. Keep runningvehicles away from the permit workspace;


iv. Maintain constant visual or voice communication between the attendant and entrantsentering a permit-required confined space using intrinsically safe communications;

v. Access spaces with engulfment hazards away from affected areas or by top entry only;vi. Communicate all air monitoring results to all entrants or their authorized

representative;vii. Protect all openings to confined spaces with barriers when hatches, covers, or lids are

removed to protect entrants and others from potential hazards;viii. When the possibility of a release of hazardous energy exists, the appropriate

lockout/tag out procedures shall be utilized;ix. Utilize all required personal protective equipment;x. In the event a hazardous atmosphere or condition is detected or suspected at any time

during a confined space entry, all personnel shall exit the space immediately andmeasures shall be implemented to protect employees from the hazards before anysubsequent entries take place; department supervisors should be notified;

xi. If an emergency rescue becomes necessary, the Entry Supervisor or Attendant shallnotify emergency services immediately and provide information, guidance andassistance as necessary to emergency services. Northwestern employees are not

permitted to enter a confined space to perform a rescue under any circumstances.

C. Post Entry

i. Upon completion of work and all personnel have exited the confined space, the EntrySupervisor will ensure that the worksite has been returned to safe conditions and willclose out the permit.

ii. The Department of Safety and Security should be notified upon completion of theconfined space entries.
