29 CFR 1910. 146 - Confined Space Standards
The purpose of this program is to ensure that CSB|OSB employees who enter and perform work in confined spaces found on campus are protected from the hazards associated with confined space entry.
This program must be observed by all CSB|OSB employees authorized to participate in confined space entry operations.
NOTE: CSB|OSB employees may NOT enter permit-required confined spaces, or any such that has hazards detected at or above permissible exposure limits. Employees may enter a permit space, which has been re-classified as non-permit required. Monitoring instruments must be used prior.
The Occupational Safety and Health Administration under 29 CFR 1910.146 established requirements for practices and procedures to protect employees from the hazards of entry into confined spaces. Examples of confined spaces found on campus include underground storage tanks, boilers, manholes, crawl spaces, electrical vaults, and cooling towers. The hazards that may be associated with these spaces include but are not limited to: hazardous atmospheres, explosive vapors, toxic chemicals, extreme temperatures, risk of drowning, or electrocution.
Attendant: An individual stationed outside one or more permit spaces who monitors the authorized entrants and who performs all attendant's duties as assigned by this program.
Authorized Entrant: An individual authorized to enter a permit space.
Confined Space: A space that:
Entry: The action of passing through an opening into a confined space. Entry includes work activities in that space and occurs as soon as any part of the entrant's body breaks the plane of an opening into the space.
Entry Permit (permit): The written or printed document that is provided by the employer to allow and control entry into a permit space and that contains specific information for entering the space safely.
Entry Supervisor: The individual responsible for authorizing entry into a permit space, determining if entry conditions are acceptable, overseeing entry operations, and for terminating or revoking the entry permit.
NOTE: An entry supervisor may also serve as an authorized entrant, provided the supervisor is trained and equipped as required. Also, the duties of entry supervisor may be passed from one individual to another during the course of an entry operation.
Non-permit-required confined space: A confined space that does not contain or, with respect to atmospheric hazards, does not have the potential to contain any hazard capable of causing death or serious physical harm.
Permit-Required Confined Space or Permit Space: A confined space that has one or more of the following characteristics:

Participating Department Directors/supervisors will identify all confined spaces that fall within their area of supervision. The confined spaces must be evaluated for hazards (both known and potential) and subsequently classified as one of the following:
The confined space will be classified as a Permit-Required Confined Space (Permit Space) if it is known or suspected to present one or more of the following hazardous conditions:
CAUTION: In the course of identifying and evaluating confined spaces, DO NOT ENTER any space known or suspected of containing any hazard listed above.
A database of campus located confined spaces that lists for each space: a brief description of the space, its location on campus, its classification, the associated hazards reported, and the name and telephone number of the Department Director or Manager who controls entry into the space, shall be maintained and made accessible to authorized personnel.
PREVENTION OF UNAUTHORIZED ENTRY INTO PERMIT SPACES
Participating Department Directors or Managers will inform employees of the existence, location, and dangers posed by permit spaces by posting a warning sign at the entrance to the permit space. The sign will read:
Where it is not possible to post a warning notice visible from outside the entry point (e.g., manholes) the sign will be posted at a location that is immediately visible upon opening of the entry point.
CSB employees are not authorized to enter any permit spaces.
Go to Confined Space index.
The hazards associated with entry to a confined space vary in degree (from least to most severe) as follows:
Entry into a Non-Permit-Required Confined Space
A non-permit-required confined space, by definition, poses no hazard to an employee more serious than its restricted means of entry and exit. Therefore, provided that the work to be performed lacks any potential to create a prohibited or unacceptable condition, entry to a Non-Permit-Required confined space may proceed as described below.
Prior to entry:
NOTE: If the work to be performed in the space has potential to create a prohibited or unacceptable condition, do NOT enter the space.
Reclassification from Permit-Required to Non-Permit-Required, Prior to Entry
Under certain conditions the Entry Supervisor may temporarily reclassify a permit space as non-permit-required. This action can facilitate entry to the space by reducing the entry requirements. The specific conditions necessary to allow this temporary reclassification are that:
A: All hazards within the permit space be eliminated prior to entry, and
B: The space poses no atmospheric hazard (actual or potential) during entry.
Condition (a) calls for elimination of all hazards through isolation techniques such as lockout/tagout, line blocking, purging, etc., which must be accomplished without having to enter the space. (See Section Atmospheric Testing).
Condition (b) requires that any atmospheric hazard eliminated by condition (a) remain eliminated throughout the duration of the entry operation. Note that the use of continuous forced air ventilation to control an atmospheric hazard does not "eliminate" the hazard and thus, does not constitute compliance with this condition.
The Entry Supervisor must prepare a Permit Space Reclassification Certificate that documents the basis for determining that all hazards in the space have been eliminated. The certification is then made available to all employees entering the space by posting of the certificate at the entry point to the space.
The reclassification remains valid only for as long as the hazards remain eliminated. If a hazard arises within a declassified space, all employees must exit the space immediately and the space be reevaluated to determine whether it must once again be classified as permit-required.
Entry into a permit space reclassified as Non-Permit-Required will proceed as detailed below.
Prior to entry, the Entry Supervisor will:
NOTE: If any prohibited condition is detected during entry, all employees will immediately evacuate the space and the Entry Supervisor will:
Upon completion of entry, the Entry Supervisor will:
RECLASSIFICATION CERTIFICATE
A Reclassification Certificate is used to conduct safe entry into permit spaces reclassified as non-permit-required. The Entry Supervisor performing a reclassification as detailed in above, will prepare a Reclassification Certificate prior to any initial entry into the permit space. Copies of such certificate must be made available to EH&S.
Duration of Reclassification Certificate
Unless revoked for cause by the Entry Supervisor, a Reclassification Certificate remains valid for the duration of the entry operation or for a single, eight-hour work shift. If necessary, the certificate may be extended for over-time work performed by the same entry crew.
Revocation of Reclassification Certificate
The Entry Supervisor will immediately revoke the Reclassification Certificate and notify employees to evacuate the space upon detection of a prohibited condition in or around the space. Likewise, the certificate will be immediately revoked and evacuation ordered if work activities deviate from those described on the certificate in a manner that threatens to introduce a hazard in or around the permit space.
Posting of Reclassification Certificate
The Reclassification Certificate will be made available for review by all employees actively involved with the entry operation by posting the certificate at the permit space entry point.
Termination and Disposition of Reclassification Certificate
The Entry Supervisor will terminate (cancel) the Reclassification Certificate upon completion of the entry operation and forward a copy of the canceled certificate to EH&S. Each canceled certificate will be retained for at least 1 year by EH&S to facilitate the review of the Confined Space Program. Any problems encountered during an entry operation will be noted on the pertinent certificate so that appropriate revisions to the program can be made.
Go to Confined Space index.
Atmospheric testing is required to evaluate the hazards of the permit space, to verify that acceptable atmospheric conditions exist in the permit space prior to entry, and to ensure that atmospheric conditions remain acceptable throughout the duration of the entry operation.
Specification of Acceptable Atmospheric Conditions
Acceptable atmospheric conditions in CSB|OSB permit spaces will meet the following specifications:
NOTE: For air contaminants for which OSHA has not determined a dose or permissible exposure limit, other sources of information, such as Material Safety Data Sheets, published information, and internal documents can provide guidance in establishing acceptable atmospheric conditions.
Evaluation/Verification Testing
To re-classify a permit space as non-permit required, the atmosphere of the space will be analyzed using a calibrated, direct reading, gas monitor of sufficient sensitivity and specificity to identify and evaluate any hazardous atmospheric condition that is known or suspected to exist. At a minimum, tests will be conducted to evaluate:
Toxicity tests for substances other than carbon monoxide and hydrogen sulfide will be required only if other toxins are known or suspected to be present in the permit space.
Go to Confined Space index.
Contractor entry operations into a CSB|OSB permit-required confined space will be performed under the contractor's own Confined Space Program. Contractors will be required to submit to the CSB|OSB Project Manager a copies of their Confined Space Programs prior to any entry.
It is the responsibility of each contractor who performs entry operations to obtain any available information regarding confined space hazards and entry operations from CSB|OSB. Contractors must also coordinate entry operations with CSB|OSB when both CSB|OSB and contractor personnel will be working in or near permit spaces.
Coordinating Entry Operations
The CSB|OSB Project Manager will inform contractors of CSB|OSB 's safety rules and emergency plans which may be applicable to the contractors' employees. Contractors and their employees must not be allowed to enter a permit-required confined space until the provisions of this program have been satisfied. When both CSB|OSB and contractor personnel are working in or near permit-required confined spaces, entry operations must be coordinated to avoid endangering any personnel.
All contractors performing entry into a permit-space will be informed of any fire, explosion, health or other safety hazards of that confined space. This information will be based on current or past history of the confined space and the nature of the work being performed by the contractor.
RESCUE AND EMERGENCY SERVICES
Each contractor who enters a permit required space is responsible for rescue operations in case of an emergency. In addition, the Fire Department that has jurisdiction, will be notified of the emergency and will be made aware of the hazards they may confront when called on to perform rescues. Upon request, CSB|OSB will provide the Fire Department with access to all permit-required confined spaces from which rescue may be necessary so that they can develop appropriate rescue plans and practice rescue operations.
If an injured entrant is exposed to a substance for which a Material Safety Data Sheet (MSDS) or other similar written information is required to be kept at the work site, that MSDS or written information will be made available to the medical facility treating the exposed entrant.

The Environmental Health & Safety will assist in providing training so that all employees whose work is regulated by this program acquire the understanding, knowledge, and skills necessary for the safe performance of the duties assigned.
Training will be provided to each affected employee:
Training will ensure employee proficiency in the duties required by 29 CFR 1910.146 and will include new or revised procedures, as necessary, to maintain compliance with this program.
EH&S will certify that the training required by the previously mentioned paragraphs has been accomplished. The certification will contain each employee’s name, the signatures or initials of the trainers, and the dates of training. The certification will be available for inspection by employees and their authorized representatives. However, employees will not be trained to enter permit required confined spaces.
The department management or EH&S will review entry operations when there is reason to believe that the measures prescribed in the Confined Space Program may fail to protect employees and revise the program to correct deficiencies found to exist before any subsequent entries are authorized.
Examples of circumstances requiring review of the program are:
EH&S will perform an annual review covering all entries performed in the twelve month period as part of the program review.
