Dear Commissioners and Staff:

Pacific Gas & Electric Company (PG&E) is requesting authorization to use Delta Protection respiratory protection suits at Humboldt Bay Power Plant (HBPP) and Diablo Canyon Power Plant (DCPP). These suits are manufactured in France and have no National Institute for Occupational Safety and Health (NIOSH) approval for use as a respirator in the United States. Pursuant to 10 CFR 20.1703(b), PG&E must request authorization from the Nuclear Regulatory Commission (NRC) for the use of equipment that has not been tested or certified by NIOSH. Pursuant to 10 CFR 20.1705, PG&E must also request authorization from the NRC before using an assigned protection factor (APF) in excess of those specified in Appendix A of 10 CFR 20. Since these suits have no NIOSH approval for use as a respirator in the United States, PG&E is requesting authorization for their use as respiratory protection equipment and assignment of an APF.

PG&E has evaluated the Mururoa V4 MTH2 and Mururoa V4 F1 models of the respiratory protection suits manufactured in France. The Enclosure to this letter provides the documentation supporting the request for authorization for the Mururoa V4 MTH2 and V4 F1 suits. As described in the enclosure, approval of this request would improve worker safety in areas of airborne radioactivity and minimize the potential for facial/skin contamination and heat stress.

Authorization to use these suits will allow PG&E to proceed with procedure changes and complete training necessary for the use of the suits during decontamination and decommissioning efforts that are scheduled to take place at HBPP in the beginning of 2006. Therefore, PG&E is requesting NRC approval by December 31, 2005.

Document Control Desk PG&E Letter DCL-05-112 October 7, 2005 HBL-05-024 Page 2 As mentioned in Section 1.3 of the enclosure, the NRC has previously authorized use of Mururoa V4 suits for Duke Energy Corporation in a letter dated June 30, 2003 (ADAMS Accession No: ML031810133), for Entergy Operations, Incorporated in a letter dated February 1, 2005 (ADAMS Accession No: ML050330405), and most recently for Florida Power and Light Company in a letter dated April 8, 2005 (ADAMS Accession No: ML050980119).

PG&E has identified the following as commitments associated with this request:

1. The Mururoa V4 F1 and V4 MTH2 single-use suits will be integrated into the PG&E respiratory program using all instructions for use and emergency features supplied by the manufacturer except for the step that involves performing a visual inspection of the suit before removing the shipping protection. PG&E proposes to perform the visual inspection after the shipping protection has been removed. See the Implementation section of the enclosure for a more detailed explanation.

2. New lesson plans will be developed to train workers on Mururoa's features, donning, use and removal, cautions and use of the mouth strip and tear off strips for routine and emergency egress. PG&E will use all instructions for use and emergency features (see Implementation section of the enclosure) supplied by the manufacturer to develop these lesson plans, with the one exception noted in item 1 above.

3. Radiation Protection personnel will be provided additional training for selection, approval, issue, equipment set-up, operation and maintenance instructions for the Mururoa suits.

4. PG&E will use the Corrective Action Program to document any unexpected problems with the suits and track corrective actions taken. PG&E will report to the manufacturer any defects or incidences that may occur with the suits.

5. All suits are understood to be "single-use," and will be discarded after a single use.

6. The Mururoa V4 F1 and V4 MTH2 suits will not be used in environments that are immediately dangerous to life and health (IDLH) atmosphere.

If you have any questions, please contact Jack Chadwick at HBPP (707) 444-0878 or Mark Somerville at DCPP (805) 545-4007.

1.0 INTRODUCTION

1.1 PURPOSE Regulation 10 CFR 20.1703(b) indicates that all respiratory equipment that is not certified by the National Institute for Occupational Safety and Health (NIOSH) must be submitted to the Nuclear Regulatory Commission (NRC) for analysis and approval based on quantified test data. Regulation 10 CFR 20.1 705 requires authorization from the NRC before using an assigned protection factor (APF) in excess of those specified in Appendix A to 10 CFR 20.

Pacific Gas and Electric Company (PG&E) is requesting authorization to use the Mururoa fully enclosed suit models V4 F1 and V4 MTH2, manufactured by Delta Protection in France, at Humboldt Bay Power Plant (HBPP) and Diablo Canyon Power Plant (DCPP). PG&E is also requesting authorization to use an APF of 5,000 with the Mururoa V4 suits. Because of the advanced safety features for emergency breathing and emergency escape built into these models, PG&E may choose to use the Mururoa V4 F1 and V4 MTH2 suits without dedicated rescue personnel.

1.2 REGULATORY REQUIREMENTS 1.2.1 Requirements of 10 CFR 20 The following regulatory requirements are relevant to this request:

Regulation 10 CFR 20.1703(a) requires that if a licensee assigns or permits the use of respiratory protection equipment to limit the intake of radioactive material, the licensee shall use only respiratory protection equipment that is tested and certified by NIOSH.

Regulation 10 CFR 20.1703(b) allows the licensee to use equipment that has not been tested or certified by NIOSH, or for which there is no schedule for testing or certification to submit an application to the NRC for authorized use of this equipment.

Regulation 10 CFR 20.1703(f) requires provision of standby rescue persons, whenever an unaided individual would have difficulty in extricating himself or herself from an atmosphere-supplying suit.

2

Enclosure PG&E Letter DCL-05-112 HBL-05-024 Regulation 10 CFR 20.1705 requires the licensee to obtain authorization from the NRC before using an APF in excess of those specified in Appendix A to Part 20.

Regulation 10 CFR 20 Appendix A, APFs for Respirators, lists as item 11, atmosphere supplying respirators (particulate, gases and vapors), suit in a continuous flow operating mode. 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., 10 CFR 20.1703).

Therefore, based on the above requirements, PG&E requests authorization to use the Mururoa V4 F1 and V4 MTH2 respiratory protection suits and an APF of 5,000 for the suits.

The technical justification demonstrates that there will be no undue hazard to life or property.

1.3 PRECEDENTS The NRC has previously authorized use of Mururoa V4 suits for Duke Energy Corporation, Entergy Operations, Inc., and most recently for Florida Power and Light Company. The following table summarizes the date of the NRC approval letters, the NRC's ADAMS accession number for each of the approval letters, the Mururoa suit model that was approved for each company and the APFs approved by the NRC per each company's request.

(g)

Instructions for Use - Mururoa V4 MTH2 and V4F1 (Attachment 5.7)

PG&E also physically inspected the Mururoa V4 F1 and V4 MTH2 suits.

The European Standard EN 1073-1 (Attachment 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 miles per hour (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 with wood chips from the base of a hopper and emptying it into the opening on top (15 minutes), should be performed by two workers at specified air flow rates.

Certificate No. 0073/197/162/12/97/0028 (Attachment 5.4) states that the Mururoa V4 F1 passed in all categories tested and provided a protection 5

Enclosure PG&E Letter DCL-05-112 HBL-05-024 factor greater than 50,000. Certificate No. 0073/197/162/01/96/0001 (Attachment 5.5) states that the Mururoa V4 MTH2 passed in all categories tested and provided a protection factor greater than 50,000. Please 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 APF used in 10 CFR 20. Based on a review of the manufacturer's documentation, the Mururoa V4 F1 and V4 MTH2 suits represent a better design than the currently approved bubble hood and rain suit combination and provide better worker protection. This data supports an APF of 5,000.

2.2 DISCUSSION 2.2.1 Suit Construction The Mururoa suit models V4 F1 and V4 MTH2 meet International Standards Organization (ISO) 8194 and EN 1073-1 standards and the manufacturer is ISO 9001 certified. The manufacturer 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 bubble hoods 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 for 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 case 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, air flow 6

Enclosure PG&E Letter DCL-05-112 HBL-05-024 (10) Two exhaust valves that provide ventilation, and also protect from overpressure (11) Very low noise level at maximum air flow (12) Air flow to hands, feet, face and chest The Mururoa V4 F1 suit shall be supplied with air at 85 pounds per square inch gauge (psig) measured at the inlet. Air hoses of any length may be used with the Mururoa V4 F1 as long at the required inlet pressure is provided. A regulator at the inlet can adjust the air flow from 41 cubic feet per minute (cfm) maximum to 9 cfm at the minimum. The regulator cannot shut off the air supply to ensure user safety. Noise level is kept between 76 decibels (dB) at maximum air flow and 58 dB at minimum air flow. Air flows through manifolds to the chest, hands and feet. There are two exhaust vents 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 nonflammable PVC, but should not be brought in direct contact with any material colder than 41 OF or hotter than 1400F. Open flames or sparks could melt or perforate the skin. The suit has a three year shelf-life and is required by the manufacturer to be stored between 320F and 1400F. The Mururoa suit is approved for use with many different fittings in Europe and can be fitted with Schrader, Foster or CEJN fittings.

The Mururoa V4 MTH2 suit is made of Ethyfuge material which is fully incinerable. This material is more flexible than the PVC used in the V4 F1 suit. The Mururoa V4 MTH2 is constructed the same way as the V4 F1 suit.

Breathing air is required at the same pressure (85 psig). The regulator can adjust air flow between 9 cfm and 41 cfm. Noise level varies from 58 dB at minimum air flow to 76 dB at maximum air flow. 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 1400F. Storage requirements are the same as for the V4 F1 suit. The V4 MTH2 suits are also available with multiple fittings.

2.2.2 Safety Features of V4 F1 and V4 MTH2 Models Both Mururoa suit models are light-weight (2.5 pounds), made of fire-retardant material and can be used in temperatures up to 1400F. 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 a six inch by eight inch clear face plate provides a distortion-free view. Dual magnetic ventilation valves provide needed ventilation and relief of excess pressure in 7

Enclosure PG&E Letter DCL-05-112 HBL-05-024 case suit is squeezed or pinched unexpectedly. Noise level at maximum air flow 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 both the V4 F1 and V4 MTH2 suits. Air flow 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. Altemately, 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. PG&E plans to use this suit for protection against radioactive particulate contamination only and not in IDLH situations. 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.

2.2.3 Implementation PG&E has a respiratory program in full compliance with 10 CFR 20. The Mururoa V4 F1 and V4 MTH2 suits will be integrated into PG&E's respiratory program using all instructions for use and emergency features (see attachments 5.1 and 5.7) supplied by the manufacturer with one exception.

Under the Dressing section of the Instructions for Use, the manufacturer describes performing a visual inspection of the suit before removing the shipping protection, which includes cardboard on the visor and inside the garment, and removable plastic protection on the visor. PG&E proposes to perform this visual inspection of the suit and its components after the shipping protection material has been removed. This will allow removing the shipping protection material outside of the contaminated area, thus, reducing the potential for radioactive waste. According to the manufacturer, both the cardboard and the plastic are used solely to maintain the integrity of the visor during transit and storage.

The Mururoa V4 Fl and V4 MTH suits are single-use suits, and each suit will be discarded after a single use.

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 with additional training for the selection, approval, issue, equipment set-up, operation and maintenance 8

Enclosure PG&E Letter DCL-05-1 12 HBL-05-024 instructions for the Mururoa suit. The safety features of the Mururoa suits, namely the tear-off mouth strip and the emergency tear-off strip, make it unnecessary for any standby rescue person to be present. Further justification for requesting exemption from the rescue person provision includes 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 via audio headsets. The ability to eliminate the rescue worker is also an As Low As Reasonably Achievable (ALARA) consideration since the work areas where air-supplied suits are used are typically areas with high surface and airborne contamination levels.

Decontamination activities in enclosed areas are specifically targeted for the use of the Mururoa suit. In addition, the suits will offer excellent protection at HBPP with respect to high alpha contamination concerns during decommissioning use.

PG&E will use the Corrective Action Program to document any unexpected problems with the suits and track corrective actions taken. PG&E will communicate problems associated with the suits, if they arise, to the manufacturer to ensure that operating experience is shared with other users.

A relationship with the manufacturer will also be developed that allows operating experience from other users to be incorporated into PG&E processes. PG&E will share this experience with the NRC and other utilities that may be interested in the Mururoa suits. PG&E will advise the manufacturer and the NRC as to any defects or concerns regarding the suits and their function. Delta Protection has in place a vendor-user alert system to report any deviations or deficiencies within the product or manufacturing process should they arise. The manufacturer is subjected to checks from the Institute for Nuclear Protection and Security (IPSN) to insure the product has no risk of injury to the user. A second organization called 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/nondestructive 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.

PG&E currently uses Powered Air Purifying Respirators (PAPR) for jobs involving high potential for skin contamination from discrete radioactive particles and to prevent intake of airborne contaminants. Because the PAPR covers only the face, workers have to wear protective clothing consisting of coveralls, a hood, gloves, shoe covers and tape for sealing. Plastic outer 9

Enclosure PG&E Letter DCL-05-112 HBL-05-024 garments may also be required if working in a wet environment. The chance of cross contamination during undressing and exit from contaminated areas is high. The Mururoa V4 F1 and V4 MTH2 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, while allowing the worker complete freedom of movement and minimizing heat stress. Approval of an APF of 5,000 for the Mururoa V4 F1 and V4 MTH2 air-supplied suits would allow use of the suits in efforts to control contamination incidents, prevent intakes, and minimize heat stress during decontamination and decommissioning evolutions at PG&E's HBPP and during steam generator replacement and reactor head replacement at DCPP.

10

Enclosure PG&E Letter DCL-05-112 HBL-05-024

3.0 CONCLUSION

Based on the physical inspection of the suits and vendor supplied documentation, PG&E has determined that the Mururoa air-supplied suits offer a safer and more efficient means to protect workers in areas of high radiological contamination, in areas where there is a potential for airborne contamination, and during evolutions which may result in worker heat stress.

The existing rain suits and bubble hoods 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.

Pursuant to 10 CFR 20.1703(b), PG&E is hereby requesting authorization to use the recently NRC approved Mururoa V4 F1 and V4 MTH2 respiratory protection suits that are manufactured by Delta Protection in France.

Pursuant to 10 CFR 20.1705, PG&E is also requesting authorization to use an APF of 5,000 with the Mururoa V4 F1 and V4 MTH2 suits. 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. Therefore, PG&E may choose to use the Mururoa V4 F1 and V4 MTH2 suits without dedicated rescue personnel present. All test results indicate that this request is reasonable, is authorized by regulation, and will not result in undue hazard to life or property.

a) for 4 h to a temperature of (-30 +/- 3) 'C and allowed to return to ambient conditions, followed by b) for 4 h to an atmosphere of (60 +/- 3) 'c at 95 % relative humidity. It shall then be allowed to return to ambient temperature.

5.2 Practical performance test 5.2.1 General The tests shall be carried out by two test persons at (20 +/- 5) '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 dB(A). 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 officers discretion. Prior to the test there shall be an examination that the suit is in working-condition and that it can be used without danger. If more than one size of clothing is manufactured the subjects are asked to select the appropriate size. Ensure that the air supply is within the specified parameters. Two 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 is 'Yes", continue the test. If the answer is "No", replace the test person or the suit.

5.2.2 Procedure During the test the following activities shall be done in simulation of the practical use of the suit:

a) the test shall be completed within a total working time of 20 min b) walking on the level with regular rate of 5 km/h for 5 min 8

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 shall be repeated 15 to 20 times in 10 min.

Figure 1: Hopper and basket 5.2.3 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 (see 5.6);

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.

5.3 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 standing still).

5.4 Determination of the protection factor The protection factor shall be determined in accordance with prEN 943-1. Sodium chloride test method shall be used. Activity sequences for testing are given in Annex A of this standard. The determination has to be done at the minimum design air flow rate (see 4.8).

Enclosure.2 PG&E Letter DCL-05-112 HBL-05-024 Page 10 EN 1073-1 :1998 On two test subjects four new suits shall be tested. Two suits per test subject.

For each individual test calculate the arithmetic mean over the time period. Calculate the percentage inward leakage (IL) as follows:

IL = C2x 100%

C, where:

C, is the challenge concentration in the test chamber, C2 is the mean concentration in the breathing zone for each exercise. For classification according to table 2, the average value for the four suits shall be taken.

5.5 Join and assemblage pull test Assemble the means of attachment according to the manufacturers' information. If the assembled item (e.g. glove or boot) is itself not strong enough to apply the required pull substitute an item that is.

Securely attach one part to a fixed clamp. Apply the required force longitudinally. Record at which force it parts or state that at the required force it was still complete.

5.6 Exhaust device pull test Mount the suit on to a dummy torso which can be adjusted so that the load can be applied axialiy to the exhaust device. A system of retaining straps or bands is fitted over the suit around the exhaust device so that the load is applied as directly as possible to the fitting of the exhaust device in the suit.

Exert a force of (50 +/- 2,5) N to the exhaust device and hold for 10 s. Repeat 10 times.

Examine the exhaust device for signs of damage or failure.

In accordance with the paragraph 4.6; the connection between the compressed air supply system and the suit has been tested for a steady pull of 250 N. The three suits have been tested successfully. However, it appears a deformation of the fabric, near the regulation air flow device. A reinforced area could certainly avoid this deformation.

NO/841 442T Enclosure INDICE: e Mururoa V4F1 and MTH2-V4.7 DATE: 12/00 PG&E Letter DCL-05-112 PAGE:1/1 HBL-05-024 INSTRUCTIONS FOR USE Preliminary remarks This clothing is to be used under the authority of the person responsible for issuing the equipment for its dedicated use:

- the clothing offers the necessary protection for it's intended use.

- Breathable air *network, hoses with connectors compatible with that of the clothing, are actually available on site and that they are capable of supplying a sufficient quantity of air:

minimum flow rate 600 liters/min. +1 0% at 6 Bars; (20 cfm at 85 psig) maximum flow rate 1200 liters/min. +1-10% at 6 Bars ; (40dfm at 85 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,a communication device, if applicable, 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 3F)

USAGE The air supply should be between + 15-C and + 45-C. ( 59'F and 113'F)

EXPIRY DATE The clothing should be used by the third year from the date of manufacture.

CLEANING Not necessary for this type of equipment which is for a single use only.

EMERGENCY FEATURES

- Air outside of the garment can be breathed by removing the safety strip at the front of the helmet/hood.

- The undressing strip, removed by the wearer, enables the wearer to self escape t in less than 5 seconds.

Breathable air: see the EN 132 standard.
