A water-based fire-fighting system required by SOLAS 2000-Amendments Regulation 10.5.6 and MSC/ Cir. 913 in order to provide early suppression of a fire in machinery space Category “A”. The main idea behind local protection is the immediate application without having to evacuate space, stop ventilation, close openings, etc. Once the system has been started all these measures required before the release of the main fire fighting system can be taken.
In principle, fire-fighting systems such as high/low-expansion foam systems, water spray, high/low-pressure water mist system may be used. The use of seawater, though not prohibited, is not desirable due to increased corrosive potential.
