Wormald U.S., Inc., Recall of Model EX607 and Model EX589 Portable Fire Extinguisher Hoses
April 10, 1986
MEMORANDUM FOR REGIONAL ADMINISTRATORS
The Consumer Product Safety Commission has brought to our attention a voluntary recall currently being conducted by Wormald U.S., Inc., on Model EX607 and Model EX589 portable fire extinguisher hoses.
Wormald advises that these hoses are used on large wheeled fire protection equipment, cartridge operated fire extinguishers, and large stationary and skid-mounted fire protection equipment. This equipment is generally referred to as "Red Line" equipment and is sold under the trademark "Ansul." EX607 hoses manufactured between 1977 and 1983 are being replaced as a result of reports received by Wormald that some EX607 hoses have ruptured under pressurization. EX589 hoses used only on Ansul Model 20 cartridge-operated Red Line hand portable extinguishers manufactured between 1983 and 1985 are also being replaced in order to change couplings which are attached to the hoses. Based on the information available to us, other Red Line equipment does not present the risk of coupling failure.
The attached Ansul Hose Replacement Identification Chart and the Ansul reprint from the January 1986 Fire Journal offer guidelines for identifying suspect hoses.
The American Welding Society Radiation Committee (American Welding Society, 550 N.W. LeJeune Road, P.O. Box 351040, Miami, Florida 33135) issued a statement two years ago that testing and research are necessary to determine the suitability for use of these devices. Mr. Marvin E. Kennebeck of the American Welding Society and Health Group was informed of the Electronics article on the Wodelic helmet. He has advised that the Radiation Committee will include the article on the agenda for its upcoming April 23 meeting.
The shortest response time of any such device predating the Wodelic helmet has been 10 milliseconds by the Swedish "Hornell" product. It is our understanding that alleged cases of eye burns have been reported with the use of this product. It is not known, however, if the product was used correctly in these cases. In conclusion, we cannot advise on the suitability of the Wodelic helmet without proper testing performed by a recognized laboratory. Such tests must be requested by the manufacturer of the helmet. Please feel free to contact Raymond G. Kunicki of my staff (FTS 523-7065) for additional information.
