CONFINED SPACES

 

 

INTRODUCTION

 

Working in confined spaces presents unique hazards because environmental conditions can change rapidly and it may be difficult to quickly exit the space.  Some of the most common problems associated with confined spaces include hazardous atmospheres (e.g. reduced oxygen, flammable, toxic), slippery surfaces, electric shock, poor illumination, and flooding.  This chapter describes the procedures to be used for entry into these spaces.  If an oxygen deficiency hazard (ODH) exists as identified by Fermilab Environment, Safety and Health Manual (FESHM) Chapter 5064 and is within a confined space, the confined space entry team is also expected to follow any training and monitoring requirements found within FESHM Chapter 5064.

DEFINITIONS

 

Acceptable Entry Conditions-Conditions that must exist in a confined space to allow entry and to ensure that employees involved can safely enter into and work within the space.

 

Authorized Attendant- A trained employee, subcontractor, or scientific user who is stationed and remains outside of the confined space for the purpose of monitoring the entrants and who performs all attendant's duties.  An attendant shall be stationed outside any confined space requiring a permit for each job assignment.

 

Authorized Entrant-A trained employee, subcontractor, or scientific user who will enter a confined space.

 

Confined Space-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; and

3.         Is not designed for continuous employee occupancy

 

“Restricted entry or exit,” means physical impediment of the body, e.g., use of the hand or a contortion of the body to enter into, or exit from, the space.  Underground beamline enclosures are not usually considered confined spaces.  Enclosures that can be accessed by a ladder with no other access/egress points are considered confined spaces.  The Landlord ES&H Department shall evaluate large-scale excavations on a case-by-case basis.

 

Confined Space Entry Permit -The written or printed document established by Fermilab, the contents of which are based on the hazard identification and evaluation for that confined space and is the instrument by which Fermilab authorizes its authorized entrants to enter confined spaces.

 

Confined Space Reclassification Form – A form that allows a division/section to reclassify a permit-required confined space as a non-permit confined space provided that certain conditions are met.

 

Construction Coordinator – A division/section designated individual specifically assigned to oversee the work of a fixed-price construction subcontract for conformance to the subcontract documents.

 

Emergency-Any occurrence or change of conditions (including any failure of hazard control or monitoring equipment) internal or external to the confined space that could endanger entrants.

 

Engulfment- The surrounding and effective capture of a person by a liquid or finely divided (flowable) solid substance that can cause death.

 

Entry-The act by which a person passes through the opening into a confined space.  The entrant is considered to have entered as soon as any part of the entrant's body breaks the plane of an opening into the space.

 

Entry Supervisor– A trained employee, subcontractor or scientific user responsible for determining if acceptable entry conditions are present where entry into a confined space is planned, for authorizing entry and overseeing entry operations, and for terminating entry.

 

Functional Landlord - Division/Section which routinely enters the confined space.

 

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 confined space) injury, or acute illness from one or more of the following causes: (1) Flammable gas, vapor, or mist in excess of 10 percent of its lower explosive limit;  (2) Airborne combustible dust at a concentration that meets or exceeds the lower explosive limit;  (3) Atmospheric oxygen concentration below 19.5% or above 23.5%;  (4) Atmospheric concentration of any substance which may exceed either the OSHA PEL or the ACGIH TLV for that substance;  (5) Any other atmospheric condition that is immediately dangerous to life or health.

 

NOTE:  For air contaminants for which ACGIH or OSHA has not determined a dose or permissible exposure limit, other sources of information, such as Material Safety Data, published information, and internal documents can provide guidance in establishing acceptable atmospheric conditions.

3.                  Permit-Required confined spaces that can be easily or inadvertently entered must be labeled with a sign outside the space that states, DANGER - CONFINED SPACE.  Other confined spaces which require keys, tools, or special procedures to enter, do not have to have signs posted outside them, as long as equally effective arrangements are made to prohibit unauthorized entry (training, special procedures, etc.).

 

4          Each division/section shall evaluate their confined space entry program on an annual basis against the requirements defined in Fermilab’s program.

 

 

PERMIT-REQUIRED CONFINED SPACE ENTRY PROCEDURES

 

Listed below are the requirements for permit-required confined space entry procedures when any Fermilab employee or scientific user (1) enters the space or (2) serves as entry supervisor.

 

1.                  Assign roles of entry supervisor, attendant, entrant. 

 

2.                  Assure that there is at least one attendant outside the permit space, into which entry is authorized, for the duration of entry operations.  The attendant may not monitor more than one confined space entry unless the Fermilab permit is amended to establish the means and procedures needed to enable the attendant to respond to one or more of the confined spaces.

3.                  The confined space entry team (i.e., entry supervisor, attendant, entrant) identifies and evaluates the hazards of the confined space before entry and indicates on the permit the potential hazards and protective measures needed.  They include, but are not limited to:

 

            Lockout/Tagout  All energy sources which are potentially hazardous to confined space entrants shall be secured, relieved, disconnected and/or restrained as per FESHM Chapter 5120 before personnel are permitted to enter the confined space.

 

            Pipelines or similar conveyances carrying any hazardous liquids or gases between the confined space and point(s) of isolation from any hazard shall be drained, cleaned or flushed of such materials as necessary to assure safety.  The pipelines may be isolated by blocking, blinding or disconnecting.

 

NOTE:  In confined spaces where complete isolation is not possible, provisions shall be made for as rigorous an isolation as practical.  Provisions shall be noted on the entry permit.

 

Ventilation shall be maintained during the occupancy of a confined space where there is a potential for the atmosphere to move out of an acceptable range.  Natural ventilation is acceptable if it is determined by the entry supervisor to achieve adequate results.

 

Personal protective equipment, i.e., gloves, coveralls, respirators, hard hats, footwear, etc. shall be available and required for use, when needed.  Personal protective equipment needed for a confined space entry will be based on the work that will be accomplished and the hazard.

 

Appropriate retrieval equipment To facilitate entry and non-entry rescues, retrieval systems shall be used whenever an authorized entrant enters a permit space.  This equipment typically includes a full body harness attached by a retrieval line to a mechanical retrieval device or to a fixed point outside the permit space.  Exceptions exist to this requirement if the use of retrieval equipment would increase the overall risk of entry or would not contribute to the rescue of the entrant.  All entrants are required to wear a full body harness, even if it is not attached to a retrieval line.

 

            Hazardous Atmosphere   Potential atmospheric hazards shall be identified before entry.  These routinely include oxygen deficiency, flammability, carbon monoxide, and hydrogen sulfide.  Other toxic chemicals are added as needed.  The atmosphere must be tested before and during entry by the attendant to assure it is within acceptable limits.  Monitor readings shall be recorded at a minimum of once an hour.  Acceptable atmospheric limits for entry are:

 

(i)         Oxygen - 19.5% to 23.5% (separate requirements are applicable to designated oxygen deficiency hazard (ODH) areas in Chapter 5064).

(ii)        Flammability - Less than 10% of the Lower Explosive Limit (LEL).

 

(iii)              Toxicity - Carbon monoxide in a confined space is 25 parts per million (ppm) and hydrogen sulfide in a confined space is 5 ppm.

 

NOTE:  Contact the Landlord ES&H Department or ES&H Section for limits on other toxic chemicals.

 

Barriers   Barriers shall be in place to protect entrants from external hazards.

 

Welding/Burning/Brazing Permit  The fire extinguishers required for this permit must be placed outside of the confined space.  All permits must be issued by the Fire Department.

 

4.                  Entry supervisor assures all attendants and entrants are trained.

 

5.                  Entry supervisor informs authorized entrants and attendants of the required safety equipment and their proper use.

 

6.                  Entry supervisor verifies, by checking that the appropriate information has been entered onto the permit, that all tests specified on the permit have been conducted, and that all procedures and equipment specified by the permit are in place before approving the permit and allowing entry to begin.

 

7.                  The attendant performs air monitoring before entry and continuously during entry for atmospheric and other hazards associated with the confined space.  As stated earlier, the attendant shall record monitoring results on the permit at a minimum of once an hour.  The entrant(s) may also be required to perform continuous monitoring for the hazards associated with the confined space in the event that the attendant is unable to monitor the immediate vicinity of the workers within the confined space.

 

8.                  The entry supervisor shall authorize the permit before entry.  A Landlord ES&H Department Senior Safety Officer or designee may be required to approve the permit before entry based upon the Landlord’s internal written requirements.  If a written approval is not practical, a verbal approval may be given and so noted on the permit.

 

9.                  The Landlord and Functional Landlord and Fire Department shall be notified prior to entry.

10.              The entry supervisor determines, whenever responsibility for confined space entry operation is transferred to another entry supervisor, that entry operations remain consistent with terms of the entry permit and that acceptable entry conditions are maintained.

 

11.              The attendant must keep in constant communication with the entrant(s).

 

12.              The attendant shall order the entrant(s) to evacuate the confined space immediately when there are:

 

a.         Condition(s) which is/are not allowed in the permitted space.

 

b.         Behavior effects of hazard exposure.

 

c.         Any situation outside of the space which could endanger the entrants.

 

d.         Sudden uncontrolled hazards within the confined space.

 

13.              When the attendant orders an evacuation, the entry supervisor shall be notified and shall cancel the entry authorization.  The entry supervisor shall notify the Landlord ES&H Department.  Re-entry will not be permitted without the written approval of the Landlord ES&H Department Senior Safety Officer or designee.

 

14.              In the event of an emergency, the attendant will contact the Emergency Operator.  If a phone is immediately available, the Operator can by reached by dialing extension 3131 or 840-3131.   If a phone is not immediately available, radio communications shall be used.  It is imperative that the attendant never enters a confined space to attempt a rescue.  In the event of a rescue situation, the attendant's main role shall be to summon help.

 

 

ENTRY PERMITS

 

Listed below are the requirements for filling out confined space entry permits when any Fermilab employee or scientific user (1) enters the space or (2) serves as entry supervisor.

 

1.                  The confined space team shall complete a permit.  Additional check-off items may be added to the permit as needed.

 

2.                  The duration of the permit will be for the length of the job, so long as the conditions remain the same.

 

3.                  In the event that unacceptable conditions arise, the attendant will order an evacuation and inform the entry supervisor.  The permit will be void, and a reevaluation will be required by the Landlord ES&H Department.

 

4.                  All significant identifiable hazards shall be listed on the permit.

 

5.                  If there is a shift change or multiple day jobs or change in entrants/attendants, a roster of entrants/attendants shall be attached to the permit if more space is needed.

 

6.                  Air monitoring records must be recorded on the permit. 

 

7.                  All canceled confined space permits shall be retained by the division/section making the entry for a minimum of one (1) year.

 

 

CONFINED SPACE RECLASSIFICATION PROCESS

 

1.                  A space classified as a Permit-Required Confined Space may be reclassified as a Non-Permit Confined Space by an individual trained in confined space entry after the following provisions have been met:

 

a.                  No actual or potential atmospheric hazard exists (determined following initial atmospheric testing).

 

b.                  All other recognized serious safety or health hazards must be eliminated without entry into the space.

 

NOTE:         If it is necessary to enter the permit space to eliminate hazards, such entry shall be performed following permit-required confined space entry procedures.  If testing and inspection during that entry demonstrates that the hazards within the permit space have been eliminated, the permit space may be reclassified as a non-permit confined space for as long as the hazards remain eliminated.

 

c.                  The basis for determining that all hazards have been eliminated must be documented using the Confined Space Reclassification Form from the ES&H Web-site.

 

NOTE:  Reclassification status may be maintained for the duration of the entry as long as the hazards remain eliminated.  In the event a change in conditions is identified or suspected by those working inside the space, the space shall immediately be vacated.  The confined space will be considered a Permit-Required Confined Space until deemed otherwise through reevaluation.

 

2.                  All completed confined space reclassification forms shall be retained by the division/section making the entry for a minimum of one (1) year.

 

3.         The Landlord and Functional Landlord and Fire Department shall be notified prior to entry.

 

 

TRAINING FOR CONFINED SPACES

 

Fermilab employees and scientific users who are designated as entry supervisors, entrants or attendants for confined space entries shall receive training (TRAIN class # FN000003-CR) prior to initial entry into a confined space.  Additional training shall also be provided when a hazard for which an employee has not previously been trained or whenever there is reason to believe there are inadequacies in the employee's knowledge.  All training records shall be entered into TRAIN.

 

Training shall include a review of:

 

1.                  The Fermilab Confined Space policy and procedures, as well as other applicable environment, safety and health procedures.
