Request for Authorization to Use Delta Protection French Designed Respiratory Protection Equipment In accordance with the provisions of 10CFR20.1703(b), PSEG Nuclear LLC (PSEG) is requesting authorization to (1) use French designed respiratory protection equipment that has not been tested and certified by the National Institute for Occupational Safety and Health (NIOSH), (2) take credit for an assigned protection factor of 2,000 for this equipment and (3) not provide standby rescue persons whenever this equipment is used.PSEG is requesting authorization to use the Mururoa V4 F1 and V4 MTH2 single use respiratory protection suits manufactured by Delta Protection in France. 10CFR20.1703(a) requires use of respiratory protection equipment that is tested and certified by NIOSH.10CFR20.1703(b) allows licenses to request authorization for use of equipment that has not been tested or certified by NIOSH.NRC guidance provided in NUREG/CR-0041 encourages the use of suits, noting that, in certain work environments, air-supplied suits may be the best respiratory application when factoring in heat stress, minimizing skin contamination, and maintaining worker doses as low as is reasonably achievable (ALARA). Additionally, Appendix A, Footnote (g) to 10 CFR Part 20 allows the use of air-supplied suits, but allows no credit to be taken for protection provided by the non-NIOSH approved units, unless approval is granted under 1OCFR20.1703(b).
Consistent with the provisions and intent of 1OCFR20.1703(b), PSEG is requesting to take credit for the protection provided by these suits to a user, specifically an APF of 2,000. As defined in 1OCFR20.1003, an APF denotes the expected level of protection that would be provided to a trained respirator user by a properly functioning respirator.
A respirator with an APF of 2,000 reduces a user's potential radioactive material intake by 99.95 percent, for JUL 0 3 2008 Document Control Desk LR-N08-0129 purposes of estimating a user's internal dose. Additionally, PSEG is requesting an exception to 10CFR20.1703(f, which requires provision of the standby rescue persons. Due to these design features of the suit, coupled with required training of all suit users on escape methods, and limiting the use of the suits to non-immediately dangerous to life and health (IDLH)atmospheres, the requirement for standby rescue persons in 10CFR 20.1703(D is not applicable.
Exelon previously received NRC approval for use of the requested suits by NRC letter dated January 31, 2005. The NRC Safety Evaluation concluded that, within the provisions of 10 CFR Part 20; no exemption was needed for the requirements of 10CFR20.1703(a) and (f).Enclosure 1 provides the documentation supporting this authorization request. As described in.the enclosure, approval will improve worker safety in areas of airborne radioactivity and high potential for facial/skin contamination.
PSEG will implement the following controls for use of these suits: 1. The Mururoa V4 F1 and V4 MTH2 single use suit will be integrated into the PSEG respiratory protection programs using the information provided by the manufacturer.
: 2. New lesson plans will be developed to train workers on Mururoa's features, donning, use and removal, cautions and use of mouth strip and tear off strips for routine and emergency egress.3. Radiation Protection personnel will be provided additional training for selection, approval, issue, equipment set-up, operation and maintenance instructions for the Mururoa suit.PSEG requests approval of this exemption by March 31, 2009, in order to support use during the Spring 2009 refueling outage.If you have any questions or require additional information, please do not hesitate to contact Mr.Jeff Keenan at (856) 339-5429.Sincerely,* -eT. e , ector-Regulatory Affairs

==1.0 INTRODUCTION==
 
===1.1 PURPOSE===
In accordance with the provisions of 10CFR20.1703(b), PSEG Nuclear LLC (PSEG) is requesting authorization to (1) to use French designed respiratory protection equipment that has not been tested and certified by the National Institute for Occupational Safety and Health (NIOSH), (2) to take credit for an assigned protection factor of 2,000 for this equipment and (3)to not provide standby rescue persons whenever this equipment is used.PSEG is requesting authorization to use the Mururoa V4 F1 and V4 MTH2 single use respiratory protection suits manufactured by Delta Protection in France. 10CFR20.1703(a) requires use of respiratory protection equipment that is tested and certified by NIOSH. 10CFR20.1703(b), allows licenses to request authorization for use of equipment that has not been tested or certified by NIOSH.NRC guidance provided in NUREG/CR-0041 encourages the use of suits, noting that, in certain work environments, air-supplied suits may be the best respiratory application when factoring in heat stress, minimizing skin contamination, and maintaining worker doses as low as is reasonably achievable (ALARA). Additionally, Appendix A, Footnote (g) to 10 CFR Part 20 allows the use of air-supplied suits, but allows no credit to be taken for protection provided by the non-NIOSH approved units, unless approval is granted under 10CFR20.1703(b).
Consistent with the provisions and intent of 10 CFR 20.1703(b), PSEG is requesting to take credit for the protection provided by these suits to a user; specifically an APF of 2,000. As defined in 10 CFR 20.1003, an APF denotes the expected level of protection that would be provided to a trained respirator user by a properly functioning respirator.
A respirator with an APF of 2,000 reduces a user's potential radioactive material intake by 99.95 percent, for purposes of estimating a user's internal dose. Additionally, because of the advanced safety features for emergency breathing and emergency escape built into these models, PSEG requests approval for the use of the Mururoa suits without dedicated rescue personnel, as required by 10CFR20.1703(f).
10CFR20.1703 (f) requires provision of standby rescue persons, whenever an unaided individual would have difficulty in extricating himself or herself from an atmosphere supplying suit. Due to these design features of the suit, coupled with required training of all suit users on escape methods, and limiting the use of the suits to non- immediately dangerous to life and health (IDLH) atmospheres, the requirement for standby rescue persons in 10CFR 20.1703(f) is not applicable.
Exelon previously received NRC approval for use of the requested suits by NRC letter dated January 31, 2005. The NRC Safety Evaluation concluded that, within the provisions of 10 CFR Part 20; no exemption was needed for the requirements of 10CFR20.1703(a) and (f).1.2 REGULATORY REQUIREMENTS The following regulatory requirements are relevant to this request: 10CFR20.1703, Use of Individual Respiratory Protection Equipment, requires that if a licensee assigns or permits the use of respiratory protection equipment to limit the intake of radioactive material.3 of 8 Enclosure 1 LR-N08-0129 10CFR20.1703(a) requires use of respiratory protection equipment that is tested and certified by NIOSH 10CFR20.1703(b) allows that if the licensee wishes to use equipment that has not been tested or certified by NIOSH, or for which there is no schedule for testing or certification, the licensee shall submit an application to the NRC for authorized use of this equipment.
10CFR20.1703 (f) requires provision of standby rescue persons, whenever an unaided individual would have difficulty in extricating himself or herself from an atmosphere supplying suit.10CFR20, Appendix A, Assigned Protection Factors, lists as item II, Atmosphere supplying respirators (particulate, gases and vapors), a suit operating in a continuous flow mode. Per footnote (g), no NIOSH approval schedule is currently available for atmosphere supplying suits. This equipment may be used in an acceptable respiratory protection program as long as all the other minimum program requirements, with the exception of fit testing, are met (i.e., 1 OCFR20.1703).
Therefore, based on the above requirements, PSEG must obtain (1) approval for the use of the respiratory protection suit, (2) assignment of a protection factor for the suit, and (3) exception to the provision of standby rescue persons.2.0 TECHNICAL JUSTIFICATION
 
===2.1 SCOPE===
PSEG reviewed the following documents from Delta Protection, France: (a) Technical information on Mururoa V4 model ventilated suits (Attachment 2.5.1)(b) European Standard CEN/TC 162 N 738 for ventilated protective clothing (Attachment 2.5.2)(c) Protection Factor determined during fit test exercises for V4 F1 (Attachment 2.5.3)(d) Certificate No. 0073/197/162/12/97/0028 for Mururoa V4 F1 issued by the Institute for Nuclear Protection and Security (Attachment 2.5.4)(e) Donning and Removal Instructions for Mururoa V4 F1 (Attachment 2.5.5)(f) Certificate No. 0073/197/162/01/96/0001 issued for Mururoa V4 MTH2 by the Institute for Nuclear Protection and Security (Attachment 2.5.6)(g) Protection Factor determined during fit test exercises for V4 MTH2 (Attachment 2.5.7)(h) Donning and Removal Instructions for Mururoa V4 MTH2 (Attachment 2.5.8)The European Standard (Attachment 2.5.2) requires that suit material be tested for resistance to abrasion, flex cracking, puncture, blocking, tear and flammability, strength of seams, joins and assemblies, damage resistance of exhaust valves, designed flow rates for pressure range of supplied air, noise level and quality of the visor. According to the testing standard, three workers should perform standard exercises; each wearing two different suits inside a chamber filled with a test agent (Sodium Chloride) and measure the leakages during the exercise regimen lasting 20 minutes. Operating parameters are set to manufacturer's instructions.
Standard exercises include walking on a treadmill at 2 mph (3 minutes), moving arms up and down above head while looking upward (3 minutes) and squatting continuously (3 minutes).
To ensure worker's comfort, two additional practical exercises
-walking at 2 mph (5 minutes) and loading a bucket 4 of 8 Enclosure I LR-N08-0129 with wood chips from the base of a hopper and emptying it into the opening on top (1 5 minutes)-should be performed by two workers at specified air flow rates.Certificate No. 0073/197/162/12/97/0028 (Attachment 2.5.4) states that the Mururoa V4 F1 passed in all categories tested and provided a protection factor greater than 50,000. Certificate No. 0073/197/162/01/96/0001 (Attachment 2.5.6) states that the Mururoa V4 MTH2 passed in all categories tested and provided a protection factor greater than 50,000. Note that the term'protection factor' used in the European Standard is equivalent to the 'fit factor' used in the United States and is not the same as the Assigned Protection Factor used in 1OCFR20. The Mururoa V4 F1 and V4 MTH2 suits represent a better design than the currently approved"bubble hood" and "rain suit" combination.
Based on a review of the manufacturer's documentation, the approved use at Exelon facilities (where PSEG personnel participated in informal trials), PSEG concludes that an APF of 2,000 is appropriate because of the enhanced worker protection provided by this respiratory device.

The manufacturer (Delta Protection) indicates that approximately 60,000 Mururoa garments/suits are used by European Nuclear Power plants each year.The Mururoa single use suits have the following desirable features that are not available in the"bubblehoods" and "rain suits" manufactured in the United States: (1) One piece single use suit that includes welded gloves and booties with tie straps.(2) Fire proof (up to 650C).(3) Made of PVC or Ethyfuge with reinforced elbows, knees and crotch areas.(4) Dual zippers -metal zipper inside and plastic zipper outside.(5) Helmet made of clear PVC material that provides distortion-free vision and large enough to accommodate wearing a headset.(6) Welded sleeve to insert communication cable.(7) A removable strip near the mouth that could be used for emergency breathing in the event of loss of supplied air.(8) An egress strip stretching from left arm, over the head, to right arm that is used for undressing and for self-rescue in an emergency, such as loss of supplied air.(9) Air intake located at the waist with a built-in regulator that can adjust, but not block, airflow.5 of 8 Enclosure 1 LR-N08-0129 (10) Two exhaust valves that provide ventilation, and also protect from over pressurization.
(11) Very low noise level at maximum airflow.(12) Air flow to hands, feet, face and chest.Air hoses of any length can be used, but air shall be supplied to the Mururoa suit (model V4 F1)at 85 psig measured at the inlet. A regulator at the inlet can adjust the airflow from 43 CFM maximum to 19 CFM at the minimum. The regulator cannot shut off the air supply to ensure user safety. Noise level is kept between 76 dB at maximum airflow to 58 dB at minimum airflow.Air flows through manifolds to the chest, hands and feet. There are two exhaust vents located on the back; one behind the neck and one at the lower back. The exhaust vents have patented magnetic seals to prevent any aspiration of contaminants if supplied air is lost. The suit is made of non-flammable PVC, but should not be brought in direct contact with any material colder than 41'F or hotter than 140'F. Open flames or sparks could melt or perforate the suit material.There is a shelf life of 3 years for this suit and storage between 32 0 F and 1400F in original packing is required by the manufacturer.
The Mururoa is approved for use with 16 different fittings in Europe and can be~fitted with Schrader or Foster or CEJN fittings used at PSEG.The Mururoa suit model V4 MTH2 is made of Ethyfuge material, which is fully incinerable.
This material is more flexible than the PVC used in V4 Fl. It is constructed the same way as the V4 Fl. Breathing air is required at about the same pressure (87 psig). The regulator can adjust airflow between 19 CFM to 43 CFM. Noise level varies from 58 dB at minimum airflow to 76 dB at maximum airflow. There are two additional air vents near the chin for cooling the face. The suit is also fire-retardant and can be used in ambient temperatures up to 140'F. Storage requirements are the same as V4 Fl. These suits are also available with multiple fittings.2.3.2 Safety Features of V4 F1 and V4 MTH2 Models Both Mururoa suit models are lightweight (2.5 Ibs), made of fire-retardant material and can be used in temperatures up to 140 0 F. Contact with open flames or grinding/welding sparks is prohibited.
Built-in gloves, booties with binding ties, reinforced elbows, knees and crotch protect against accidental tear, puncture and cracking.
A transparent helmet with 6" X 8" clear faceplate provides distortion-free view. Dual magnetic ventilation valves provide needed ventilation and relief of excess pressure in case suit is squeezed/pinched unexpectedly.
Noise level at maximum airflow is less than 80 dB. Length of air hose supplying Grade D breathing air is not stipulated, but the pressure of air at inlet is required to be 85 psig for V4 F1 and 87 psig for V4 MTH2. Airflow can be adjusted by the user for his/her comfort, but cannot be shut off. In case of loss of air, the user can remove the mouth strip and move the opening close to his face, or enlarge the opening, to breathe outside air. Alternately, the user can pull the escape strip from either forearm, over the head and towards the other forearm, and rip the suit in two halves. This escape strip is normally used for egress from the suit when the work activity has been completed.
The Mururoa suit's design does not permit its use in an immediately dangerous to life and health (IDLH) atmosphere.
PSEG plans to use this suit for protection against radioactive particulate contamination only. The Mururoa suit is also not designed for use with any personal cooling units such as a Vortex tube, but can be used with a cooling vest supplied by the manufacturer, if desired.6 of 8 Enclosure 1 LR-N08-0129
 
====2.3.3 Evaluation====
 
Conclusions Based on the approved use at Exelon facilities (where PSEG personnel participated in trial use)and the information received from the manufacturer, PSEG has determined that the Mururoa V4 F1 and V4 MTH2 air supplied suits offer a safer and more efficient means to protect workers in areas of high radiological contamination and in areas where there is a potential for airborne contamination.
The existing rain suits and bubblehoods provide cooling only to the head and force workers to wear the ensemble in a manner that makes self-rescue nearly impossible, thus requiring a rescue worker to be stationed nearby. Ease of removal of the Mururoa suit provides for more desirable self-rescue features, and provides a means to undress that minimizes the potential for personnel contamination events.2.3.4 Implementation PSEG has respiratory programs in full compliance with 10CFR20. The Mururoa V4 F1 and V4 MTH2 suits will be integrated into PSEG's respiratory programs using the information provided by the manufacturer.
New lesson plans will be developed to train workers on Mururoa's features, donning, use and removal, cautions and use of mouth strip and tear off strips for routine and emergency egress. Radiation Protection personnel will be provided additional training for selection, approval, issuance, equipment set-up, operation and maintenance instructions for the Mururoa suit. Instructions will require suit disposal after each use.The Mururoa suit's safety features, namely the tear-off mouth strip and the emergency tear-off strip, make it unnecessary for any standby rescue person. Further justification for requesting exemption from the rescue person provision include the fact that workers wearing air-supplied suits are typically under continuous surveillance by Radiation Protection technicians using remote video monitoring or under direct Radiation Protection surveillance at the job location due to radiological conditions.
Additionally, in many cases, workers are in direct contact with Radiation Protection and work support personnel via audio headsets.
The ability to eliminate the rescue worker is also an ALARA consideration since the work areas where air-supplied suits are used are typically areas with higher radiation and contamination levels. Steam Generator platform work, Cavity decon, equipment decontamination, and under vessel CRD work are specifically targeted for the use of the Mururoa suit. Use of these suits related to the Hope Creek 1 OCFR Part 72 license will primarily be for activities around the spent fuel pool involving spent fuel cask evolutions in support of Independent Spent Fuel Storage Installation activities.
PSEG intends to adhere to all of the manufacturers "instructions for donning and removal","instructions for use", and "emergency features" technical information/directions provided, with one exception.
PSEG will not incorporate the "instructions for donning and removal", Attachment 2.5.5, Caution Step 2, which states, "The buddy system must be in effect with the use of this suit fed with a sufficient breathable air source with either both persons in it or the second person nearby in view with a particulate respirator ready." As discussed previously, the inherent safety features of this suit (mouth and wrist tear-away strips), combined with the use of headsets for communication and remote video monitoring, make the use of a stand-by rescue person or "buddy system" unnecessary.
Additionally, it is noted that PSEG standard practice is to have individuals standing by to assist workers in removing the suits.PSEG will use the Corrective Action Program (CAP) to document any unexpected problems and track corrective actions taken. Problems associated with the suits will be communicated to the manufacturer to ensure that operating experience is shared with other users. Upon discovery of manufacturer defects or usage problems identified by PSEG, the problem will be entered into the 7 of 8 Enclosure 1 LR-N08-0129 PSEG corrective action program. The PSEG corrective action program will enter identified manufacturer defects or significant usage problems into an Operating Experience Report issued to the nuclear power industry via the INPO Nuclear Network. Additionally, procedural guidance will be established to ensure that PSEG identified defects and usage problems are reported to the suit manufacturer.
The vendor has committed to report product issues on a quarterly basis. Delta Protection has in place a vendor-user alert system so as to report any deviations, or deficiencies within the product and manufacturing process should they arise. The manufacturer is subjected to checks from the International Product Safety News (IPSN) to insure the product has no risk of injury to the user. A second organization called Quality Service Association (ASQUAL) performs annual inspections of the factory to certify that the product manufactured is of the same quality approved by the IPSN Notified Body. Several destructive/non-destructive tests are performed by the manufacturer for each order received from clients. Any defects reported by clients, investigations and corrective actions are documented.
Customers are notified of any problems and products are recalled if necessary.
This information is made available to ASQUAL for their annual inspections.
PSEG currently use the bubblehood for work involving high potential for skin contamination and to prevent intake of airborne contaminates.
Because the bubblehood covers only the face and torso, workers have to wear appropriate protective clothing to protect the remainder of their body. Chances of cross contamination during undressing/exit from contaminated areas are high.The Mururoa suits offer a better alternative (with their unitized construction and ease of removal)and should protect the worker much better against facial/skin contamination and airborne radioactivity.
Approval of a protection factor of 2,000 for the Mururoa suits would allow use of the Mururoa suits in PSEG's efforts to control contamination incidents and prevent intakes during operational activities.
 
==2.4 CONCLUSION==
 
In accordance with 1OCFR20.1703(b), PSEG is requesting authorization to use the Mururoa V4 F1 and V4 MTH2 respiratory protection suits that are manufactured by Delta Protection in France. Based on the approved use at Exelon (where PSEG personnel participated in trial use)and review of manufacturer information, the Mururoa suits offer a safer and more efficient means to protect workers in areas of high radiological contamination and in areas where there is a potential for airborne contamination.
PSEG is also requesting authorization to use an APF of 2,000 with the Mururoa suits. The manufacturer's documentation supports the requested APF.Additionally, the Mururoa suits have advanced safety features for emergency breathing and emergency escape. These advanced features allow self-rescue during emergencies to be a reasonable expectation; and limiting the use of the suits to non- immediately dangerous to life and health (IDLH) atmospheres, the requirement for standby rescue persons in 1OCFR 20.1703(f) is not applicable.
Therefore, PSEG is also requesting exception from 1OCFR20.1703(f) in order to use the Mururoa suits without dedicated rescue personnel.
Exelon previously received NRC approval for use of the requested suits by NRC letter dated January 31, 2005. The NRC Safety Evaluation concluded that, within the provisions of 10CFR Part 20; no exemption was needed for the requirements of 1OCFR20.1703(a) and (f).8 of 8 Enclosure 1 LR-N08-0129 ATTACHMENT

/ EXHAUST In the supplied-air Mururoa suit, the ventilation system is composed of-An airflow control valve, preset to a minimum flow of 250 litres/minute (9 CFM) at 3 bar (42 PSIG), located on the right hip and covered with a protection flap. This flow can be adjusted, from 250 to 1150 litres (9 CFM to 41 CFM) per minute. 1150 litres is obtained with the tap fully opened at the feeding pressure of 6 bar (85 PSIG) (refer to graph in annex 11).-A silencer bag which attenuates the noise level less than 58 dBa at 250 litres/minutes to 76 dBa at 1150 litres/minute.
-A manifold system welded to the suit and distributing the air to the helmet, the legs and the arms.-An exhaust by two world patented valves placed in the helmet and in the back. These valves ensure a remarkable airtight seal in case of accidental air-feed cut off, or when putting the suit in under pressure through abrupt movements.
The valves regulate the overpressure in the garment between 3 mbar (0.042 PSIG) and 10 mbar (0. 142 PSIG)for supply air pressure between 3 bar (42 PSIG) and 6 bar (85 PSIG)-The benefits of this system are-High heat removal through superior airflow-Non irritating diffuse ventilation

====6.1.4 Preconditioning====
 
for the practical performance test If the manufacturer does not state the preconditioning atmosphere for the practical performance test.the complete clothing shall be exposed: a) for 4 h to a temperature of (-30 t 3) *C and allowed to return to ambient conditions, followed by b) for 4 h to an atmosphere of 160 +/- 31 "C at 95 % relative humidity.
It shall then be allowed to return to ambient temperature.
 
===6.2 Practical===
 
performance test 6.2.1 General The tests shall be carried out by two test persons at (20 +/- 5i 'C and a relative humidity of less than 60 %. The test temperature and humidity shall be recorded.
The background noise shall not be greater than 75 dBlAl.The test persons shall be selected who are familiar with using such or similar protective clothing.
The persons will be drawn from those people certified as fit to do so by the medical officer. The necessity of a medical examination before or supervision during the tests shall be at the testing orricers Ciscretion.
Prior to the test there .s an examination that the suit is in working-conditton and that it can be used without danger. If more than one size of a clothing is manufactured the subjects are asked to select the appropriate size. Ensure that the air supply is within the specified parameters.
Twc suits shall be tested.each being tested on one test person.After fitting the suit each test person is asked "Does the suit fit?'. If the answer s 'Yes", continue the test. If the answer is -No-. replace the test person or the suit.
Page 10 prEN 1073-1 : 1996 6.2.2 Procedure During the rest the following activities shall be done in simuiaiocn of the practical use of the suit:-the test- shall be completed within a total working time of 20 min-walking on the level with regular rate of 5 km h" for 5 min-filling a small basket (see figure 1. approximate volume 8 1l with 12 mm chippings (e.g. limestone chippings) or other suitable material from a hopper which stands 1,5 m high and has an opening at the bottom to allow the contents to be shovelled out and a furdher opening at the top where the chippings may be returned.
The person stoops or kneels as he wishes and fills the basket with chippings.
He then lifts the basket and empties the contents back into the hopper. This is reoeated 15 to 20 times in 10 min Figure 1: hopper and basket 6.2.3 Information to be recorded During the practical performance test the clothing shall be subjectively assessed by the wearer and the following shall be recorded: a) harness comfort Isee 6.61;b) security of fastening and couplings; c) accessibility of controls and pressure gauge (if fitted);d) clarity and field of vision from the facepiece and/or visor;e) clothing comfort;f) ease of speech transmission; g) any other comments volunteered by the wearer.6.3 Measurement of minimum and maximum air flow rate Connect the ends of the distribution system collectively to a suitable measuring device. Record the maximum air flow delivered at the manufacturers' specified air supply. If a control valve is fitted, record the maximum delivered air flow and the minimum delivered air flow.The value of minimum and maximum air flow rate shall be determined under the condition of exercise 6 of Annex A !person szanding sr'il.6.4 Determination of the protection factor The protection factor shall be determined in accordance with prEN 943-1. Sodium chloride test method shall be useC. Activity sequences for testing are given in Annex A of this standard.The determination has to be done at zhe minimum design air flow rare Isee 5.2.7).On tvo test subjects four new suits snail be tested. Two suits per test subject.

It is the responsibility of the supervisor to qualify, by preliminary test, the ability of the suit to protect the wearer against the harmful atmosphere in each specific environment CAUTIONS 1) Care must always be taken due to the asphyxiation hazard.2) The buddy system must be in effect with the use of this suit fed with a sufficient breathable air source with either both persons in it or the second person nearby in view with a particulate respirator ready.3) Suit removal under ordinary circumstances requires an assistant.
: 4) Thorough knowledge of the safety features of the Mururoa are essential for safety!a) a safety strip for breathing can be pulled open should air supply be restricted.
b) a safety strip for suit egress in an emergency is available by using pull tab on each elbow.c) do not over tighten any tape applied to the suit as it will prevent rapid suit removal.5) An air supply of 1 to 3 minutes exists inside the suit should the air supply fail.During that time, due to the magnetic exhaust valves, the garment will remain overpressurised, avoiding penetration of harmful atmospheres as long as portions of the remaining air have not been forced out of the suit such as if the wearer bends over and forces air out the discharge valves.

: 3) Near the job site remove garment from the bag, shake open and inspect for obvious defects.4) Inspect the emergency egress strip to ensure that the strip can be removed easily if desired.5) Remove the cardboard and the clear plastic faceplate protector.
Remove the paper sheet placed in the head position.
Discard these.6) In the donning and removal area, verify that the local breathable air supply is working properly.7) Connect the garment to the local air supply with a flexible hose. Take care that the hose goes through the throttle valve by using the loop at the back right side of the suit.8) Don the suit from the back with the help of the assistant.
Connect the MURUPHONE phonic system if used and check.9) Bind the shoe joints with the shoe strips and apply tape, if necessary, to the suit gloves.10) Zip up the mechanical zip.11) Zip up the external plastic gas sealing zipper when the suit is inflated.Apply an adhesive tape of sufficient width on the second zip-fastener to be shure no leak occurs.12) Check the air supply valve and adjust to the desired flow for comfort.13) Perform several crouching exercises to ensure the exhaust valves work; the air source is sufficient to recharge the suit to its full volume quickly and to check for leaks.14) Proceed to the job site and begin to work. You can disconnect the hose from the air line, and travel from the donning area to the working area to reconnect your suit at the step off pad;after having insured the air source in the working area is well fed and if the time, disconnected is not more than a few dozen of seconds.15) Comfort in breathing and in temperature can be maintained by adjusting the air inlet regulating valve during work.CAUTION Should the Mururoa feel hot, deflate, or if fog appears on the faceplate, leave immediately and quietly the working area and contact your assistant for suit removal.Remember: 1) The air supply of 1 to 3 minutes exists inside the suit after breaking of air supply feeding.2) The suit emergency strips are there for your use if needed.

+1- 10% at 6 Bars (17 cfm at 87 psig)maximum flow rate 1100 liters/min.
+1- 10% at 6 Bars ; (38cfm at 87 psig)DRESSING-The wearer, with a helper, visually inspects the condition of the garment and its components, then removes the shipping protection (cardboard on the visor and inside the garment, and removable "plastic protection" from the visor).-He enters through the rear opening of the garment and insures that his legs are in the garment.-Connects to the breathable air network by passing the supply line through the loop at the rear of the garment, at the same height as the supply valve.-Connects, if used, the MURUPHONE system, or other communication device through the safety loop and communication loop and finishes dressing.-The helper zips up the dual zipper system and applies a large strip of adhesive tape to the upper extremity of the second zipper at the top to ensure air tightness.
He then, ties the over boot laces around the ankles.-The wearer can control the air supply by turning the adjustment knob. The correct functioning of the supply flow valve and the over pressure valves can be verified by crouching down rapidly a few times.-He then is free to enter the work zone.UNDRESSING
-Undressing may be done in the following manner. While the garment is still being supplied with air, the helper pulls on the orange undressing strip, which runs from one wrist to the other over the hood. Once the undressing strip is removed, the helper can split the suit shell by pulling on the hooded area and separating the suit into two identical pieces. The helper rolls up the front and rear parts in a way that traps the contamination and avoids all contact with the wearer of the garment. (Please consult our video for detailed undressing techniques).
IMPORTANT-Leave the work zone immediately if the clothing deflates during the work phase evolution If the helmet fogs, or if the person has a feeling of excessive warmth.-Remember that the clothing remains pressurised for a few minutes in case of an air supply failure STORAGE In the original packaging; out of the light; between + 5'C and + 45'C.( 41 'F and 11 3&deg;F)USAGE The air supply should be between + 150C and + 45'C.
