DRAFT IE INFORMATION NOTICE N0.
FIRE EXTINGUISHER NOTICE:
HOSE MAY RUPTURE DURING OPERATION IN A FIRE EMERGENCY Addressees:
All nuclear power reactor. facilities holding an operating license (OL) or a construction permit (CP), research and test reactor licensees, fuel cycle
~
licensees, and material licensees.
Purpose:
This Information Notice is to alert licensees of an announcement made by Ansul Fire Equipment Company in the January 1986 Fire Journal, published by the National Fire Protection Association, regarding the potential fcilure of-EX-607 and EX-589 model hoses on Ansul fire extinguishing equipment. The EX-607 and EX-589 hoses are manufactured by Uniroyal and Goodyear, respectively.
It is expected that licensees will review the information for applicability to their facilities and consider actions, if appropriate, to preclude use of these potentially defective' fire extinguisher hoses.
It is our understanding that these hoses are used by at least two other companies, Badger and General Fire Equipment Companies. Suggestions contained in this notice do not constitute NRC requirements;.therefore, no specific action or response is required.
DRAFT Description of Circumstances:
The Ansul announcement indicated that a small number of Underwriter Laboratories listed fire extinguisher hoses, Model Number EX-607 (manufactured I
by Uniroyal), have failed. These are used on Ansul Red Line cartridge-operated hand-held portable types; wheeled extinguishers; stationary units; and hoses-l provided as replacement for Ansul Red Line equipment. Ansul emphasized that the EX-607 hose may rupture during operation rendering the unit inoperable i
and possibly causing injury to the person using the fire extinguisher.
The Ansul announcement also warned that in a few instances the hose coupling on certain model EX-589 extinguisher hoses (manufactured by Goodyear) had separated from the hose.
It is believed that this extinguisher hose type is also used with the portable hand-held cartridge-operated extinguishers, wheeled extinguishers, and stationary extinguishers. Badger and General Fire Equipment Companies also supply fire extinguishers using these type hoses.
Ansul has initiated a program (free of charge) to replace the EX-607 and EX-589 hoses. No information is available on programs that may have been
)
initiated by Badger or General Fire Equipment Companies.
No specific action or written response is required to this Infonnation Notice.
If you have any questions regarding this matter, additional information may be obtained by calling Ansul's toll-free telephone number.
