10 Ten-year service
At least once every 10 years, the following inspections should be carried out for the specified equipment:
10.1 Fixed gas fire-extinguishing systems
.1 perform a hydrostatic test and internal examination of 10 per cent of the
system's extinguishing agent and pilot cylinders. If one or more cylinders fail, a total of 50 per cent of the onboard cylinders should be tested. If further cylinders fail, all cylinders should be tested;
.2 flexible hoses should be replaced at the intervals recommended by the
manufacturer and not exceeding every 10 years; and
.3 if permitted by the Administration, visual inspection and NDT
(non-destructive testing非破坏性试验) of halon cylinders may be performed in lieu of hydrostatic testing.
10.2 Water mist, water spray and sprinkler systems
Perform a hydrostatic test and internal examination for gas and water pressure cylinders according to flag Administration guidelines or, where these do not exist, EN 1968:2002 + A1.
10.3 Fixed dry chemical powder systems
Subject all powder containment vessels安全壳 to hydrostatic or non-destructive testing carried out by an accredited可信的 service agent.

关于消防水带长度的规定
根据SOLAS公约第II-2章“构造-防火、探火和灭火”第10条“灭火”第2.3款“消防水带和水枪”中的规定：
“消防水带的长度应至少为10 m，但不超过下述长度： .1 机器处所，15 m；
.2 其他处所和开敞甲板，20m；和
.3 最大型宽超过30 m 船舶的开敞甲板，25 m。”
也即是说，配备在机舱、舵机房的消防水带长度不超过15米，配备在生活区、物料间等处所的水带长度不超过20米，最大型宽超过30米的船舶配备在主甲板的水带长度不超过25米。
目前供应上船的消防水带长度一般为20米，如果直接配备在机舱、舵机间，将违反SOLAS公约的规定。
请各自管船尽快检查核对机舱、舵机间等机器处所的消防水带长度是否合乎规定。对于长度超过15米的水带，应进行更换或剪短处理。
