The commercial and industrial property insurer An individual or company who, through a contractual agreement, undertakes to compensate specified losses, liability, or damages incurred by another individual. An insurer is frequently an insurance company and is also known as an underwriter. found problems in some Central Sprinkler Model GB fire sprinklers that could prevent them from working in a fire. FM Global, the brand name for Factory Mutual Insurance Co. and its subsidiaries, said it had not received any reports of GB sprinklers failing to operate during a fire. Its recommendation followed reports from building owners who saw leakage LEAKAGE. The waste which has taken place in liquids, by their escaping out of the casks or vessels in which they were kept. By the act of March 2, 1799, s. 59, 1 Story's L. U.

GB sprinklers indicates that the problem appears to be the result of water leakage past the O-ring seal found in sprinklers manufactured before 2000. Additional testing revealed that while all the sprinklers operated, a few required extra water pressure. Although the problem was identified in the GB sprinklers, the company recommended that property owners immediately replace any sprinkler with signs of problems. FM Global wants its insureds to report problems to their local offices. Those who suspect problems may be asked to send samples to Factory Mutual Research's labs for testing. "Based on the limited data collected to date, it appears that this problem has affected a small percentage of the approximately 28 million GB sprinklers manufactured with O-rings since 1988," said Joseph Hankins, a senior engineering specialist at Factory Mutual Research. "If you don't see encrustation, corrosion or signs of leakage, the technical data collected so far seems to indicate there is little reason for immediate concern." Factory Mutual Research is continuing its investigation and will post additional findings on the FM Global Web site at www.fmglobal.com/news. |
