4.3.5 Document all satisfactory and unsatisfactory results on PBF-4077d.
4.4 Annual Maintenance NOTE.: Use only manufacturer's approved replacement parts.
4.4.1 Replace the two charcoal.(Part No. 46727) (Lot No. 915-0184) and one air particulate (Part No. 79030) (Lot No. 912-0297) filters.:in the MSA manifold inlet filter assembly whenever an abnormal odor is detected.and on an annual frequency-as a minimum.
4.4.2 Inspect the.0-rings and gaskets used in the inlet filter assembly when replacing the filters and replace if wear or deterioration is observed.
4.4.3 Post the date of the filter change on the filter.cover.
4.4.4 Change outthe filter on the Bullard airline filter (Part No. 41-AF)
(Lot No. 915-2808). The lhead bolts on the filter are to be tightened'to 60 ft/lbs.
4.4.5 The filter on the Bullard airline filter should also be changed when user smells or tastes contaminants in the air, or a large pressure drop.is noted across the filter.
4.4.6 Post the date of the filter change on the Bullard airline filter housing.
4.4.7 Document the results on PBF-4077d for MSA manifolds.
4.5 Annual Calibration of MSA Manifold Pressure Gauges Send each pressure gauge to I&C for calibration on an annual basis.
4.6 Repair 4.6.1 Repairs are to be made only by personnel trained to repair the equipment.
4.6.2 Use only manufacturer's approved replacement parts for the repair of Bullard airline filter, supplied-air hoses,.and manifolds. If any reasonable doubt exists regarding the integrity of a supplied air hose, remove it from service.
4.6.3 The regulator in the MSA manifold assembly will be sent to the manufacturer for repair whenever repair is required.

POINT BEACH 'NUCLEAR PLANT HPIP 4.51.3 l HEALTH PHYSICS IMPLEMENTING PROCEDURES Revision 8 May 7, 2004 AIR LINE RESPIRATORY EQUIPMENT 4.7 Air Supply Hood Respirator Inspection NOTE: Air supply hood respirators must be inspected prior to use.
4.7.1 Inspect all air supply respirator hoods for material softness, clarity, cracks, and seam strength.
4.7.2 Ensure.that the complete assembly consists of hood and cape, air distribution unit with supply air hose, and belt assembly prior to issue. Make sure that the air distribution unit is'snapped securely into place.
NOTE: A shelf life of three (3) years is recommended as a safety precaution;
'however, this is not'mandatory if a visual 'inspection of all components is made in accordance with Step 4.6.1 and found to be satisfactory prior to putting the respirators'in service.
4.7.3 Hoses should be inspected -fortears and cracks, excessive wear and material memory.
4.7.4 CEJN fittings are recommended for supply hoods and associated airline hoses.
4.8 Supply Air Hose and Extension Hose Assembly 4.8.1 Guidance for assembly.of air supply hose:
- a. Obtain a section of 3/4" ID blue hose (Lot No. 915-1844).
- b. Attach to the 3/4" ID bluehose at one end a standard'.3/4" barbed fitting.
Use two hose clamps and secure the fitting.
- c. At the other end of the 3/4" ID bluelhose, attach a Gates coupling or equivalent (PBNP No. 915- 839). Use two hose clamps and secure the fitting.
- d. To the threaded end of the 'Gates coupling, install a Schrader Bellows quick connect coupling check unit (Lot No. 915-1841).
NOTE: Air supply respirator systems are normally used with approximate 25-50 foot length of air supply hose but may be used with extension hoses as approved by RP management personnel.
4.8.2 Guidance for assembly of air supply extension hose:
I a. Obtain a section of 3/4" ID blue hose (Lot No. 915-1844).
POINT BEACH NUCLEAR PLANT HPIP 4.51.3 HEALTH PHYSICS IMPLEMENTING PROCEDURES Revision 8 May 7, 2004 AIR LINE RESPIRATORY EQUIPMENT
- b. At both ends of the 3/4" ID blue hose, attach a Gates coupling or equivalent (Lot No. 915-1839). Secure each coupling with two hose clamps.
- c. To the threaded efid of one of the Gates coupling, install a Schrader Bellows quick connect coupling check unit (Lot No. 915-1841).
- d. To the threaded end of the other Gates coupling, install a Schrader Bellows quick connect couplings adapter (Lot No. 915-1843).
4.9 Bullard Airline Filter Assembly Replace the filter (Lot No. 915-2808) 4.9.1 Shut off air supply and check that there is no moisture in filter if filter is being used, and disconnect the.filter.
4.9.2 Separate the filter-head from housing by removing the fasteners.
4.9.3 Remove the filter cartiddge, clean the inside of filter housing.
4.9.4 Insert new filter (Part'No. 41-AF) (Lot No. 915-2808) into the housing, and put on filter head.
