美国海岸警卫队发布了关于船舶固定防火系统压力开关位置的一项新的预警。美国法规要求这种压力开关应当安装在该保护区的范围之外。根据报告，在没有按照上述要求安装压力开关的情况下，火灾事故数量有所上升。
压力开关是固定防火系统的一个关键组件。它能在监测到火灾时使火灾发生区域的通风系统自动关闭。

Pressure Switch Location for Fixed Fire Suppression Systems – USA
The United States Coast Guard (USCG) have released a new alert concerning the location of pressure switches for vessel fixed fire suppression systems. US regulations require this pressure switch to be located outside the area it protects and have reported an increased number of fires where this has not been the case.
The pressure switch is a critical component of the fixed fire suppression system which activates to automatically close the areas ventilation system when a fire is detected.
