D. BACKGROUND:

A Confined Space Entry Program is required by the Occupational Safety and Health Administration (OSHA). The specific program requirements are stated in 29 CFR 1910.146 and

ANSI/ASSE Z117.1.

E. APPLICABILITY AND SCOPE:

The program applies to all Agriculture Research Service (ARS), Beltsville (BARC, BHNRC, and USNA) personnel that enter into confined spaces in accordance with 29 CFR 1910.146, Permit- Required Confined Spaces. The program applies to all Agriculture Research Service; Beltsville confined space entry operations. It sets forth requirements, standards, procedures, recordkeeping and reporting systems appropriate to provide safe confined space entry to Beltsville operations which require work in and around such spaces.

F. PURPOSE:

The purpose of this program is to provide specific procedures/safe work practices for employees required to enter confined spaces. These procedures/practices will be implemented in compliance with all applicable state and federal regulations pertaining to confined space entry.

G. POLICY:

No person will be permitted to enter or work in, on, or adjacent to an area that may contain or produce hazardous atmospheres except under the conditions and precautions contained in this program. Testing and Confined Space Entry Permits will not be provided for contractor operations. The contractor shall provide an Entry Supervisor and the appropriate equipment in order to test and permit the confined space in accordance with 29 CFR 1910.146, and must comply with any other applicable parts of this and other regulations listed in Paragraph O, References. The Beltsville Confined Space Entry Contractor Specification is attached as Appendix E. Where Beltsville personnel and contractor personnel are to occupy the same space for a given task or operation, the space in question will be tested and permitted for the Beltsville personnel by the affected Management Unit's Entry supervisor(s). However, such testing, permitting, and subsequent notification will in no way relieve the contractor of any pertinent statutory obligations for the safety and health of contractor personnel and the contractor will be so informed.

H. RESPONSIBILITIES:

1. Center Director(s) shall:

(a) Have ultimate responsibility for the Confined Space Entry Program for BARC, BHNRC or USNA and must provide continuing support for the Beltsville Confined Space Entry Program. 29 CFR 1910.146(c)(1) The employer shall evaluate the workplace to determine if any spaces are permit-required confined spaces.

1. The Entry Supervisors have the compliance authority to order anyone out of an area immediately or to suspend operations if they determine that an UNSAFE condition exists.

Entry Supervisors will notify SOHES of this condition; in turn SOHES will promptly notify the Area Safety and Health Manager of any work stoppage and the reason for such action.

2. The Management Unit Entry supervisor(s) and SOHES are authorized access into all spaces within the confines of Beltsville for the purposes of performing official duties under the Confined Space Entry Program.

J. CONFINED SPACE ENTRY:

1. Operation Evaluation:

Prior to starting any operation that involves entry or work on, in, or adjacent to confined spaces, the Management Unit Entry Supervisor(s) will comply with the requirements of 29 CFR 1910.146. Assistance and information is available from the SOHES Office. All operation evaluations will include, but are not limited to, the following considerations:

(a) Contents and/or previous contents of the space that may result in the presence of oxygen-depleted or enriched atmospheres, flammable, or toxic contaminants.

(b) Location and configuration of the space including restricted access, obstructions, remoteness, etc., which may inhibit or interfere with movement, ventilation, rescue, and firefighting efforts.

BARC, BHNRC, USNA - Confined Space Entry Program Page 11 of 16

(c) Types of operations that are conducted within the space, particularly those that by the very nature of the process produce toxic and/or flammable atmospheres, oxygen depletion or enrichment, or ignition sources.

(d) Fixtures, devices, or equipment within the space that may create or contribute to hazardous conditions including piping systems, conduits, ducts, machinery, pressurized lines, etc.

(e) The presence of other hazards such as slippery surfaces, deteriorated or unstable ladders, irritant or caustic materials, etc.

(f) Boundary spaces and their contents to ensure that fire or explosion will not be caused in these spaces by the operation to be conducted.

2. Testing:

The testing and examination of a confined space will, as a minimum, incorporate the following sequentially listed procedures:

(a) Pre-calibration of all test equipment will be performed in accordance with standard operating procedures and manufacturers' recommendations. All calibrations must be logged and be signed by the calibrator.

(b) Initial testing will be performed from outside the space. Initial testing in the interior of the space may be performed by insertion of sample probes into the space.

(c) Tests for oxygen content will be conducted first utilizing an approved and calibrated oxygen meter. The oxygen level should be 20.9%, since the normal oxygen level of ambient air at sea level is 20%. Oxygen levels less than 19.5% or greater than 22% represent potentially dangerous situations and entry will not be permitted under these conditions.

(d) An approved and calibrated combustible gas indicator will be used to test for combustible vapors. The lower explosive level (LEL) for combustible vapors must be zero.

(e) Tests will be made for the presence of specific toxics dependent upon the nature of the space and its contents or previous contents. See Subpart G, Occupational Health and Environmental Control, or in Subpart Z, Toxic and Hazardous Substances for safe levels.

(f) If initial tests indicate the presence of hazardous concentrations of flammables, toxics or deviations in oxygen levels, personnel will not enter the space. The space will be ventilated and/or cleaned in a safe manner to remove flammable and toxic atmospheres and provide proper oxygen levels.

BARC, BHNRC, USNA - Confined Space Entry Program Page 12 of 16

(g) If initial tests do not indicate the presence of hazardous concentrations of flammables or toxics or deviations from the normal oxygen levels, the space may be entered and the tests described in paragraphs 2 (c), (d), (e), and (f) will be performed continuously throughout the space by the Management Unit Entry Supervisor(s). The readings of the continuous monitoring (tests) will be recorded on Appendix A at fifteen (15) minute intervals. If subsequent tests indicate the presence of hazardous concentrations of flammables, toxics or deviations from normal oxygen levels; the Management Unit Entry Supervisor(s) will evacuate workers and the space will be ventilated and/or cleaned as necessary.

(h) The space will also be inspected for the presence of blisters or scale that may trap hazardous substances or for other residues that may become dangerous during the course of the work being performed. Additionally, any specific structure, equipment, or location that may be affected by the intended work will be tested and/or inspected as applicable.

(i) Post-calibration of all test equipment will be performed in accordance with standard operating procedures and manufacturers' recommendations.

3. Securing Area:

(a) All confined space entrances will be posted as a confined space and the potential hazards will be denoted, see attached Appendix A and paragraph 3 (b).

(b) All entry areas, when open, shall be guarded by a railing, pedestrian or vehicular barriers, temporary covers, or other barriers that will prevent accidental falls and foreign objects from entering the space.

4. Permitting:

(a) Upon completion of the evaluation and testing, a Confined Space Entry Permit, attached as Appendix A, will be issued by the Management Unit Entry supervisor(s). A copy of this permit will be posted at the main or most commonly used entrance to the space and at all other access areas that are open and readily accessible to personnel.

(b) A permit must be completed for all tests and distribution of copies will be done in accordance with this program. A Confined Space Entry Permit will not be in effect longer than eight (8) hours.

(c) For confined spaces where the only hazard is atmospheric and ventilation alone can control the hazard, Management Unit personnel may use "Alternative Protection Procedures" for entry. Spaces that are considered "Alternate Protection Procedure" confined spaces exempt the Management Unit personnel from using a permit.

"Alternative Protection Procedure" confined spaces do require the use of the Alternative Protection Procedures attached as Appendix C.

BARC, BHNRC, USNA - Confined Space Entry Program Page 13 of 16

5. Monitoring:

Once the confined space has been certified for the operations to be performed, all work will be monitored by the Management Unit Entry Supervisor(s) to ensure that the policies, procedures, and requirements of this program are being followed.

6. Ventilating Confined Spaces:

(a) Mechanical ventilation systems shall be set at 100% outside air. Where possible, open additional manholes, hatches, etc., to increase air circulation.

(b) After ventilating period that provides several air changes in the confined space, repeat the testing. Continue to ventilate until testing has demonstrated that the hazardous atmosphere has be eliminated.

(c) Ventilation air shall be clean and uncontaminated. Confined spaces will be continuously ventilated during all operations to ensure that the atmosphere within the space remains safe. Short circuiting of ventilation air flow shall always be avoided. Never ventilate a confined space where combustible gas or vapor levels have been measured to exceed 50%. When levels are above 50% LEL immediately notify the Fire and Rescue Service (9-911) and SOHES.

7. Respirators:

(a) Respirators are required as an alternative to ventilation, or when ventilation does not adequately reduce or remove a hazardous substance for an employee, required to enter a confined space, shall be appropriate for the hazard/situation. The selection of the appropriate respirator will be made in accordance with the ARS Beltsville Respiratory Protection Program.

(b) Supplied Air or Self-Contained Breathing Apparatus Respirators will provide:

(1) Air capacity sufficient to perform task. This may require more than one tank depending on the task.

NOTE: The time spent in confined space while wearing supplied air or self-contained breathing apparatus respirators must be monitored.

(2) Reserve air supply for emergency situations.

K. STANDBY/RESCUE WORK PRACTICES:

1. An attendant will stand by at the scene of each confined space entry where a Confined Space Permit is issued and will, in case of any emergency, be able to establish immediate contact with emergency rescue personnel (9-911). This can include radio and/or telephone communication.

BARC, BHNRC, USNA - Confined Space Entry Program Page 14 of 16

2. The local rescue and emergency service personnel will serve as the rescue control point for all confined space operations. Under no circumstances will unprotected, untrained persons enter a space to attempt rescue of a person overcome by toxic gases or oxygen deficiency.

Rescue will be undertaken only by trained rescue personnel properly equipped to perform the task.

L. INSTRUMENTATION:

Atmospheric testing instruments require calibration and will be calibrated in accordance with manufacturer's instructions immediately prior to and after each work shift or test procedure in which the instruments are used. A log will be maintained by the Management Unit Entry Supervisor(s) and copies of all instrument calibration checks will be provided to SOHES monthly.

Test instruments or their component parts when repaired or changed will be annotated in the log and on the instrument.

M. RECORDKEEPING:

1. A list of the current designated confined space areas for Beltsville is attached as Appendix F.

A master Confined Space Entry Log consisting of copies of all permits issued for testing and inspections of confined spaces at Beltsville will be maintained by SOHES. The Management Unit Entry Supervisor(s) will be responsible for maintaining a log for their specific area.

Permits will be maintained for a period of one (1) year from the date of the last permit issued.

2. The master copy of the records for maintenance and calibration of all confined space entry instrumentation will be kept by SOHES.

3. The master copy of the Management Unit Entry Supervisor(s) training certifications will be maintained by SOHES. Each Entry Supervisor(s) will be issued a training certification after completion of the required training and then annually after the certification training.

N. TRAINING:

1. All designated Management Unit Entry Supervisor(s) will be initially trained and certified in accordance with 29 CFR 1910.146, Permit-Required Confined Space and ANSI/ASSE Zl17.1, Safety Requirements for Confined Spaces. An annual recertification training review is required for all Entry Supervisor(s).

2. Attendants, entrants and other associated confined space personnel will only be required to receive initial training in the hazards of confined spaces and the safety precautions necessary to control such hazards.

PERMIT REQUIRED CONFINED SPACE ENTRY PROCEDURES

BEFORE ARRIVAL AT JOB SITE:

1. Entry supervisor gets permit from his/her supervisor.

2. Entry supervisor assigns jobs and reviews the jobs as a team.

3. Collects and inspects the equipment specified on the permit.

4. Turn on the air monitor and conduct the pre-calibration checks (pump check, field check with span gas, audible and visual alarm check, and then zero.)

BEFORE ENRY AT THE JOB SITE:

1. Set up traffic control and confined space equipment.

2. Zero the air monitor.

3. Perform Lockout/Tagout all energy systems.

4. Remotely monitor the air around and in the space before ventilating.

5. Ventilate as long as the Lower Explosive Level (LEL) readings are less the 50% LEL. Assume readings >50% LEL are above the Upper Explosive Level (UEL) which are too rich to burn. If the real concentration is above the UEL, ventilating the space may bring the concentration down into the flammable range (between LEL and UEL). A spark in this environment could lead to an explosion or fire. Report these readings immediately to your supervisor, SOHES, and the fire rescue services (9-911). Do not ventilate any space unless the readings are <50% LEL as indicated on the air monitoring equipment.

BARC, BHNRC, USNA - Confined Space Entry Program Page 2 of 2

Appendix B (Cont.)

6. Set up and start the blower.

7. Monitor the air in the space again to ensure acceptable entry conditions.

8. When conditions are acceptable, entry supervisor signs the permit.

9. Permit is prominently posted next to the permit required confined space.

10. Check all communication equipment or review all non-verbal communications.

11. Ensure authorized entrant has donned their proper PPE is hooked up to lifeline and the retractable lifeline (if practical), steps into the opening, and communicates to the attendant as they enter the permit required confined space.

12. The Entry Supervisor(s) will continuously monitor air readings while entrant is in the confined space. These readings will be recorded on Appendix A every fifteen (15) minutes.

13. If a prohibited condition occurs, all entrants evacuate the permit confined space. The Entry

Supervisor will contact SOHES of the prohibited conditions. After the space has been evacuated, steps 4 thru 8 will need to be repeated before reentry can occur.

14. When the entry operations are completed, the entry supervisor completes the permit. The permit will then be sent to SOHES for review and record keeping.

RESCUE:

1. If a prohibited condition occurs and the entrant is injured or unresponsive, the attendant will initiate rescue and emergency procedures.

2. The attendant will contact the rescue and emergency services indicated on the permit.

3. The attendant will then contact the Entry Supervisor and SOHES of the situation.

4. The attendant WILL NOT enter the permit required confined space to rescue the injured entrant.

Only trained personnel in confined space rescue will enter the space to perform rescue actions.

ALTERNATIVE PROTECTION PROCEDURES

For permit required confined spaces where the only hazard is atmospheric and ventilation alone can control the hazard, Beltsville personnel may us “alternative protection procedures” for entry. The communications manholes and the catch-basins in Beltsville fall into this category unless otherwise noted. Spaces that are considered “alternative procedure” spaces exempt the Beltsville personnel from using the Beltsville Confined Space Entry permit, a space entry team, and arrange for rescue. ARS Beltsville must ensure that workers entering such spaces have confined space entry training. To qualify for alternative procedures as par 29 CFR 1910.146(c)(5) Beltsville must:

1. Demonstrate that the only hazard of the permit space is an actual or potential hazardous atmosphere.

2. Demonstrate that ventilation alone is sufficient to maintain the permit space for entry and work to be performed within the permit required space must introduce no additional hazards.

3. Gather monitoring and inspection data to support #1 and #2.

4. If entry is necessary to conduct initial data gathering, perform such entry under the full permit required confined space program.

5. Document the determinations and supporting data and make information available to employees.

ALTERNATIVE PROCEDURES CAN TAKE PLACE AFTER:

a. The Entrant Supervisor(s) determines that it is safe to remove the entrance cover.

b. Guard any openings to protect against falling and falling objects.

c. Testing the atmosphere with a direct-reading calibrated air monitor the tests for oxygen levels, LEL, and potential toxic air contaminants (such as carbon monoxide, and hydrogen sulfide).

Remotely monitor the air around and in the confined space before ventilating.

d. Ventilate as long as the LEL reading are less than 50%. Assume readings >50% LEL are above the UEL (too rich to burn). If the real concentration is above the UEL, ventilating the confined space may bring the concentration down into the flammable range (between LEL and UEL).

Even a spark could start a fire or cause an explosion. Report these reading to immediately to your

Appendix C (Cont.)

supervisor, SOHES, and rescue service. Do not ventilate unless the readings are >50% LEL.

With LEL readings that high, such a space would not be classified as an “alternate procedure” space.

e. Set up and run the blower.

f. Monitor the air in the confined space again to ensure acceptable entry conditions.

g. Continuously ventilate and monitor the confined space to ensure the air remains without hazards whenever any Beltsville personnel enter the confined space.

h. Employees must exit immediately if a hazardous atmosphere is detected during entry, and the confined space must be evaluated to determine how the hazardous atmosphere developed.

i. While OSHA’s alternate procedures require only one person for entry, these are the minimum requirements. Alternative procedures at Beltsville are conducted with two personnel, an entrant and an attendant. There must be an emergency action and rescue plane in effect prior to entry.

CONTRACTORS

OSHA also has requirements whenever contractors are performing Permit Required Confined Space (PRCS) work your site. These requirements can be found in 1910.146(c)(8) and include:

1. Inform the contractor that the workplace contains PRCSs and the entry is only allowed through compliance with a PRCS program that meets the following requirement:

a. The employer must inform the contractor of the elements, including the hazards identified and the host employer's experience with the space and why the space is a PRCS.

b. Inform the contractor of any precautions or procedures that the host employer has implemented for the protection of workers in or near PRCSs where contractor personnel will be working.

c. Coordinate entry operations with the contractor when both host employer personnel and contractor personnel will be working in or near PRCS as per 1910.146(d)(11): Develop and implement procedures to coordinate entry operations when employees of more than one employer are working simultaneously as entrants in the PRCS so that employees of one employer do not endanger the employees of any other employer.

d. Debrief the contractor at the conclusion of the entry operations regarding the PRCS program followed and regarding any hazards confronted or created in the PRCS during entry operations.

In addition to complying with PRCS requirements that apply to all employers, easch contractor as per 29

CFR 1910.146(c)(9) must:

1. Obtain any available information regarding PRCS hazards and entry operations from the host employer.

2. Coordinate entry operations with the host employer when both host employer personnel and contractor personnel will be working in or near PRCS as per 1910.146(d)(11): Develop and implement procedures to coordinate entry operations when employees of more than one employer are working simultaneously as entrants in the PRCS so that employees of one employer do not endanger the employees of any other employer.

3. Inform the host employer of the PRCS program that the contractor will follow and of any hazards confronted or created in permit spaces, either through a debriefing or during the entry operation.
