9. Cable, hoses, and other equipment shall be kept clear of passageways, ladders, and stairways.

10. All hollow spaces, cavities, or containers shall be vented to permit the escape of air or gases before preheating, cutting, or welding.

Department of Transportation, Office of Pipeline Safety, 49 CFR Part 192, Minimum Federal Standards for Gas Pipelines, shall apply when welding, cutting, and heating on steel pipelines containing natural gas. Pipelines containing gases or flammable liquids or conduits containing electrical conductors shall not be used as a ground return.

11. When welding or cutting must be done an AF Form 592 USAF Welding, Cutting and Brazing Permit shall be obtained. Contact the WPAFB Fire Prevention Office at (937) 257-4075 at least 24 hours in advance to request a permit. Weekend Permits can only be authorized by the Contracting Officer who shall notify the Fire Prevention Office that work is authorized, Notification must be accomplished before Friday morning for permits to be issued for weekend work. The location shall be checked for latent fires after the work is completed.

12. Cylinders shall be kept beyond the range of sparks, hot slag, or flame and properly secured in a valve upright position. Backflash devices shall be installed on all tanks at the regulator location.

13. Positive mechanical and/or personal protective measures shall be taken when welding, cutting, or heating metals of toxic significance in enclosed spaces.

SECTION 01 01 50 Page 9

14. Oxygen shall not be used for ventilation, comfort cooling, blowing dust from clothing, or for cleaning the work area.

15. Before welding, cutting, or heating is commenced on any surface covered by a preservation coating whose flammability is not known, a test shall be made to determine its flammability. Preservation coatings shall be considered to be highly flammable when scrapings burn with extreme rapidity.

16. Precautions shall be taken to prevent ignition of highly flammable hardened preservation coatings. When coatings are determined to be highly flammable, they shall be stripped from the area to be heated to prevent ignition.

17. In enclosed spaces, all surfaces covered with toxic preservatives shall be stripped of all toxic coatings for a distance of at least 4 inches from the area of heat application or the employees shall be protected by air line respirators.

18. In the open air, workers shall be protected against toxic preservation coatings by a respirator that meets the requirements of NIOSH.

19. Preservative coatings shall be removed a sufficient distance from the area to be heated to ensure that the temperature of the unstripped metal will not be appreciably raised.

20. When the welding, cutting, or heating operation is such that normal fire prevention precautions are not sufficient, additional personnel shall be assigned to guard against fire and instructed in anticipated fire hazards and how fire fighting equipment is to be used.

21. Hose which has been subject to flashback, or which shows severe wear or damage, shall be tested to twice the normal pressure to which it is subject but in no case less than 300 psi. Defective hose, or hose in doubtful condition, shall not be used.

22. No welding, cutting, or heating shall be done where the application of flammable paints, or the presence of other flammable compounds, or heavy dust concentrations creates a hazard.

23. Noncombustible barriers shall be installed below welding or burning operations in or over a shaft.

24. When welding, cutting, or heating is performed on walls, floors and ceilings, the same precautions shall be taken on the opposite side as are taken on the side on which the welding is being performed.

25. All structural welding accomplished by the contractor on critical items such as scaffolding, shoring, forms, ladders, piling, Gas and Fuel Lines, etc., shall be performed by certified welders using qualified welding procedures. The contractor shall provide copies of the welders certificate to the Contracting Officer and the Fire Prevention Inspector when Requested.

F. Gas Equipment

1. Torch valves shall be closed and gas supply shut off whenever work is suspended for 30 minutes or more.

SECTION 01 01 50 Page 10

2. The torch and hose shall be removed from confined spaces whenever work is suspended.

3. All oxyacetylene or other fuel gas-oxygen combinations used in cutting or welding equipment shall have reverse-flow check valves between torch and regulator. Manifold systems shall have the reverse-flow valves installed at the manifold connections.

4. Boxes used for the storage of gas hose shall be ventilated.

5. Acetylene regulators shall not be adjusted to permit a discharge pressure greater than 15 psig.

6. Connection of multiple sets of oxyacetylene hoses to a single regulator on a single set of oxyacetylene tanks may only be accomplished by installing a commercially available fitting approved by Compressed Gas Association (CGA) Standards and UL listed. The fitting shall be installed on the output side of the regulator and shall have a built-in shut-off valve and reverse-flow check valve on each branch.

G. Electric Equipment

1. Switching equipment for shutting down the welding machine shall be provided on or near the welding machine.

2. The noncurrent carrying metal parts of electrically powered welding machines shall be grounded. Grounding circuits, other than by means of the structure, shall be checked to ensure that the circuit between the ground and the equipment to be grounded has resistance low enough to permit sufficient current to flow to cause the overcurrent device to interrupt the circuit.

3. Neither terminal of the welding generator shall be bonded to the frame of the welder.

4. Pipe lines containing gases or flammable liquids or conduits carrying electrical conductors shall not be used for a ground return circuit.

5. The equipment shall be shut down when the leads are unattended.
