UNITED STATESNUCLEAR REGULATORY COMMISSIONOFFICE OF NUCLEAR REACTOR REGULATION &OFFICE OF NUCLEAR MATERIAL SAFETY AND SAFEGUARDSWASHINGTON, D.C. 20555May 16, 1994NRC INFORMATION NOTICE 94-35: NIOSH RESPIRATOR USER NOTICES, 'INADVERTENTSEPARATION OF THE MASK-MOUNTED REGULATOR (MMR)FROM THE FA Ee1JCE ON THE MINE SAFETYAPPLIANCES MSA COMPA"R SELF-CONTAINEDBREATHING APPARATUS t AND STATUS UPDATE"

Addressees

All holders of operating licenses or construction permits for nuclear powerreactors, and all licensed fuel facilities.PurgoseThe U.S. Nuclear Regulatory Commission (NRC) is issuing this informationnotice to alert addressees to two recent respirator user notices issued by theNational Institute for Occupational Safety and Health (NIOSH) of theDepartment of Health and Human Services concerning the unexpected separationof mask-mounted regulators from self-contained breathing apparatus (SCBA)facepieces during firefighting activities. It is expected that recipientswill review the information for applicability to their facilities and consideractions, as appropriate, to avoid similar problems. However, suggestionscontained in this information notice are not NRC requirements; therefore, nospecific action or written response is required.

Description of Circumstances

On February 23, 1994, NIOSH issued a respirator user notice (Attachment 1)describing factors that can contribute to the separation of mask-mountedregulators from SCBA facepieces. The unexpected separation of a mask-mountedregulator could result in an individual being unprotected in an environmentthat might pose an immediate threat to the life and health of that individual.These regulators are used on mask-mounted regulator SCBA with the followingNIOSH certification numbers: TC-13F-256, TC-13F-257, TC-13F-258, andTC-13F-302. The affected regulators have a quick-connect mechanism and aredesignated as Mine Safety Appliances Company part number 492488.In addition, the respirator user notice applies to certain Mine SafetyAppliances Company combination air-line and SCBA devices with the followingcertification numbers: TC-13F-266 and TC-13F-267. The affected regulatorshave a quick-connect mechanism and are designated as Mine Safety AppliancesCompany model number 7-1047-1.9405110141 P RL c35- AM Lo0I(t.,f jLa vo, 148 '

IN 94-35May 16, 1994 Mask-mounted regulator and combination air-line and SCBA devices withregulators that attach to the facepiece with a threaded connector are notaffected by the respirator user notice.On March 31, 1994, NIOSH issued a respirator user notice status update(Attachment 2), describing the development of a Neckstrap/Regulator-RetainerKit by Mine Safety Appliances Company and accepted by NIOSH. Thisneckstrap/regulator-retainer, when properly installed, provides a lock for theregulator-to-facepiece connection. The user notice update states that thisretainer must be installed on all Mine Safety Appliances Company mask-mountedregulator respirators used at temperatures below 32 degrees Fahrenheit (F) inorder to maintain the NIOSH approval. Although NIOSH believes that propermaintenance will prevent these failures in warm-weather service, NIOSHsuggests continual use of the retainer to prevent further occurrences ofinadvertent regulator/facepiece separation.Licensees may wish to share this information with other potential users, suchas local fire departments.This information notice requires no specific action or written response. Ifyou have any questions about the information in this notice, please contactthe technical contacts listed below or the appropriate Office of NuclearReactor Regulation project manager.Robert F.

The affectedregulators have a quick-connect mechanism and are designated as MSA part number 492488.In addition this User Notice applies to certain MSA combination air-line devices with the followingcertification numbers: TC-13F-266 and TC-13F-267 (combination air-line and SCBA). The affectedregulators have a quick-connect mechanism and are designated as MSA model number 7-1047-1.It should be noted that MMR and combination air-line and SCBA devices with regulators that attachto the facepiece with the threaded connector are not affected by this Notice.If the MMR separates from the facepiece, the wearer is left unprotected. Such a separation could belife threatening since these SCBA may be used in immediately dangerous to life and healthenvironments.The manufacturer has identified three contributing factors that can lead to regulator separation:1. Lack of lubrication of the facepiece adapter 0-ring. Not lubricating this O-ring will greatlyincrease the force required to insert the second-stage regulator into the facepiece. This canresult in a user believing the regulator is locked into the facepiece when it is actually onlyheld in by the friction of the 0-ring. If the regulator is not properly locked into thefacepiece, subsequent disengagement can occur. The manufacturer has published the properlubrication procedure for the facepiece adapter 0-ring which must be followed to ensureproper operation. The manufacturer has reported that many users are not lubricating thisO-ring.2. Dirt and debris in the quick-connect mechanism. Dirt and debris in the quick-connectmechanism can prevent it from properly locking into the facepiece. The manufacturer haspublished a procedure for the proper cleaning of the quick-connect mechanism, as describedin MSA's Product Information News, Number 2, June 1992.3. Ice formation in the quick-connect mechanism during cold weather operation. If water entersthe quick-connect mechanism and freezes during cold weather operation the regulator may notproperly lock into the facepiece. Care must be taken before the regulator is inserted into the Attacb 1ent 1 Pageafacepiece to ensure that any Ice formation Inside the quick-cornect mechanism will notinterfere with its ability to return to the locked position. This can be done by operating thequick-connect mechanism and visually checking to make sure the mechanism is workingproperly prior to insertion of the regulator into the facepiece.In the Interim, MSA recommends the following: (1) Follow the manufacturer's instructions regardingthe proper lubrication and cleaning of the quick-connect mechanism. (2) Make sure the quick-connectmechanism is operating properly prior to inserting it into the facepiece. (3) Follow the proceduredetailed in the MSA Level I instruction manual including checking the regulator-to-facepiececonnection by grasping and pulling on the regulator. Perform this check often during use to ensurethe regulator is properly secured. Contact your local MSA office at 1-00-672-2222 if you havequestions or need to obtain Instruction manuals or maintenance Instructions for the proper use andcare of the MMR SCBA.In addition to these three known causes for regulator disengagement, there have been several fieldreports that Ice buildup on the second-stage regulator and facepiece assembly may cause inadvertentdisengagement. In subfreezing temperatures ice may form on the junction between the facepiece andthe quick-connect handwheel. When this junction is not free to rotate, force on the air-lineconnecting the air bottle to the regulator may activate the quick-disconnect and cause inadvertentseparation to occur. The investigation into the role that ice buildup plays in inadvertent regulatordisengagement is continuing by both MSA and NIOSH. Further information will be released as itbecomes available.At this time, NIOSH does not recommend removing the MMR SCBA from warm-weather service;the cleaning and lubrication procedures recommended by the manufacturer seem sufficient to eliminatethe possibility of inadvertent warm-weather MMR separation. However, in subfreezing temperaturesin the presence of water spray, NIOSH recommends against the use of MMR SCBA. Thisrecommendation stands until data and information are sufficient to convince NIOSH that inadvertentMMR separation is not possible for a properly used and maintained SCBA. Because of the life-threatening implications of any SCBA failure, NIOSH considers the possibility of any failure to beunacceptable.Users of MSA MMR SCBA who have experienced inadvertent regulatorlfacepiece separations, orother failure modes, are encouraged to report these incidents to both NIOSH and MSA. Informationshould be forwarded in writing to NIOSH in care of Mr. Tim Merinar, NIOSH, Certification andQuality Assurance Branch, 944 Chestnut Ridge Road, Morgantown, West Virginia 26505 and MSA incare of Mr. Charles Seibel, Manager of Product Safety, MSA, P.O. Box 426, Pittsburgh,Pennsylvania 15230 or by telephone at 1-800-672-5555 (FAX 412-967-3309). Separations or anyother failures involving any SCBA should also be reported to NIOSH.

Theseregulators are used on MMR SCBA with the following certificationnumbers: TC-13F-256 (30-minute low-pressure SCBA), TC-13F-257(30-minute high-pressure SCBA), TC-13F-258 (60-minute high-pressure SCBA), and TC-13F-302 (45-minute high-pressure SCBA).The affected regulators have a quick-connect mechanism and aredesignated as MSA part number 492488.These regulators are also used on certain MSA combination airlinedevices with the following certification numbers: TC-13F-266 andTC-13F-267 (combination airline/SCBA). The affected regulatorshave a quick-connect mechanism and are designated as MSA modelnumber 7-1047-1.A Neckstrap/Regulator-Retainer Kit has been developed by MSAand has received NIOSH acceptance. This neckstrap/regulator-retainer, when properly installed, provides a lock for theregulator-to-facepiece connection. This retainer mqust beinstalled on all USA MMR respirators usea at temperaturesbelow 32 degrees Fahrenheit (F) in order to maintain the NIOSHapproval. Although not required at temperatures above32 degrees F, continual use of the retainer will preventfurther occurrences of inadvertent regulator/facepieceseparation, should the quick-disconnect mechanism fail to lockproperly when inserted into the facepiece.Use of the neckstrap/regulator retainer is not a substitutefor following the manufacturer's recommendations formaintenance and use. Failure to properly lubricate thefacepiece adapter O-ring can result in increasing the forcenecessary to insert the MMR. Failure to properly clean andmaintain the quick-disconnect mechanism can result in thebuild-up of dirt and debris in the locking mechanism. Both ofthese conditions can result in the regulator failing to Attachment 2-- Page 2properly lock onto the facepiece, thus making inadvertentregulator/facepiece separation likely, even at temperaturesabove 32 degrees F. The Institute has requested that NSAdistribute the neckstrap/regulator retainer to all end usersof MMR SCBA, as well as provide it on all new purchases.In the February 23 Respirator User Notice, NIOSH recommendedthat MMR SCBA not be used at temperatures below 32 degrees Fin the presence of water spray. This recommendation is nolonger in effect for those respirators that have theneckstrap/regulator retainer properly installed. All field-deployed MMR SCBA used at temperatures below 32 degrees F musthave the neckstrap/regulator retainer properly installed.Contact MSA for the specific details regarding the availabilityof the Neckstrap/Regulator Retainer Kit.
