Dry Chemical Powder (DCP) Fire Extinguisher
The DCP Fire extinguisher is highly suitable for fires involving metallic substances and liquid oils. However, it can be used on all classes of fires. The principle of the DCP extinguisher is to interrupt the flame chemistry by quenching free radicals. Additionally, it supports a smothering process to extinguish the fire.
Fire extinguishers are of utmost importance inside ships due to the unique and critical nature of the marine environment. Ships are confined spaces with limited access to emergency services, making it essential to have adequate firefighting equipment on board to handle potential fire incidents. Therefore, compartments inside ships are equipped with CO2 fire extinguishers, AFFF fire extinguishers, or DCP fire extinguishers, depending on the type of fire that could potentially occur in each compartment.
DCP fire extinguishers are always available in machinery compartments and on Helo Decks during helicopter landing operations. The extinguisher is painted red.
