process and emergency procurement of additional equipment in addition to equip-l ment operating instructions.
CONDITIONS AND PREREQUISITES O
A.
Airborne conditions exist requiting the use of SCBA equipment, or 4
B.
The Radiological Emergency Coordinator (R.E.C.).has required use of SCBA due to the potential for airborne conditions.
1 PRECAUTIONS A.

PERSONNEL REQUIRED Radiological Emergency Coordinator - In Charge Maintenance Group Personnel to fill and run bottles as required Radiation Protection Personnel to issue respirators DISCUSSION A.
In the event of radioactivity release determined or estimates to be equivalent to or greater than the levels contained in Guide #1, " Radioactive Effluents" for an Alart in Procedure A.2-101, " Classification of Emergencies", and if directed by the R.E.C., SCBA use may be required to perform Plant Emergency Functions.
B.
SCBA use may also be required for d 11ing with non-radiological hazards.
C.
Scott " Air-Pak II" 1)
Description The Scott " Air Pak II" is a self-contained unit.
The cylindgr is fully charged at 2215 psig, contains an equivalence of 45 ft of air at STP, and is designated to provide maximum mobility and supply approximately 30 minutes of breathable air to the user.
The unit provides personnel with adequate respirator protection while perform-ing work in objectional and unbreathable atmospheres regardless of oxygen deficiencies.
The face mask consists of a single lens facepiece, soft rubber sealing surfaces and c speaking diaphragm.
The regulator is chest mounted and contains a tank pressure gauge, regulator shut-off valve (yellow) and a regulatot bypass valve (red). A double action alarm rings and vibrates to warn of low cylinder pressure. The weight of the unit is 30 pounds.

Protection Factor
(
)
When used in the supply demand regulated mode, the Scott Self-Contained Breathing Apparatus may be used when the airborne radioactive particu-late
- ivity, radioiodine vapors and radiogases are less than 50 times MPCa. When used in the constant flow mode, the Scott " Air-Pak" may be used shen the airborne radioactive particulate activity, radioiodine vapors and radiogases are less than 10,000 times MPCa. This respirator has no protection for tritium oxide.
PROCEDURE STEP 1 Check individuals GDE Respirator File for medical qualifications, respirator training and Scott mask fit dates.
If any date is greater than 15 months old the SCBA should not be issued.
NOTE:
In situations where the health or safety of the general public or individuals is concerned, this requirement may be waived by the Emergency Director or Radiological Emergency Director.
STEP 2 Check SCBA bottle to ensure pressure indicates in yellow region, approximately 2215 psi.
If not, replace bottle.
STEP 3 Issue SCBA units and instruct users to follow Attachment #1, SCBA Donr.ing and Usage Procedure.
(/
NOTE:
SCBA equipment may be used by any qualified personnel without being issued by Radiation Protection if an emergency exists and approved by the Emergency Director.
STEP 4 Ensure that the Maintenance Group personnel are available to transport and refill SCBA bottles per Attachment #2 and #3.
STEP 5 Ensure all SCBA units and bottles are cleaned, inspected, repaired and deconned if necessary.
STEP 6 Return equipment to storage areas or off-site sources.

Procedure A.2-409 Revision 0 Page 4 of 7 ATTACIIMENT #1 SCBA DONNING AND USAGE PROCEDURE PROCEDURE CAUTION:
SCBA should not be used by personnel not trained in their use.
STEP 1 Don all protective clothing required by RWP(s) or the REC.
STEP 2 Don air pak.
Fasten chest strap and waist belt. Adjust harness to fit.
STEP 3 Check regulator hose coupling for tightness.
Open cylinder valve at least two full turns.
Check that cylinder valve is locked open by safety lock lever by attempting to close the valve.
Check regulator gauge for full indication.
STEP 4 Adjust straps on mask " Full Out".
Put mask on chin first and tighten neck straps, temple straps, and head straps in that order.
STEP 5 Close mask hose quick-connect coupling with palm of hand and inhale slowly. Mask should collapse and stay collapsed until you exhale.
Test exhalation valve by exhaling with hose still closed off.
~~ STEP 6 h.egulator bypass valve should be closed (red knob turned fully clock-wise) and regulator shutoff valve should be open (yellow knob turned lf fully counterclockwise), and demand lever should be off.
STEP 7 Con-t mask hose quick-connect couplins to the regulator when ready to ente, contaminated area.
STEP 8 Should automatic demand regulator become dan. age J or inoperative, open emergency bypass valve (red knob) first. Depr.ss locking tab and close regulator shutoff valve (yellow knob). Adjust bypass valve to suit user's requirements then leave contaminated area.
NOTE 1:
STEP 8 is for emergency use only.
The duration of air supply is reduced.
Use for escape from area, not to continue work.
STEP 9 When Pak-Alarm Bell in the regulator starts ringing, it is a warning that only 20-25% of air remains in cylinder.
Leave the contamination area at once.
STEP 10 Return all used Scott Air Pak's to a designated area for cleaning, inst
- ion and reuse, if necessary.
NOTE:
See E.1.5.V.D.2 for Scott Air Pak maintenance.
