CCOL - Compartment Check-Off List
Provide an itemized list of all classified fittings and closures used in damage control to set the specified material condition of readiness
Halon System
Halon 1301 is used to extinguish large class Bravo fires. It inhibits the chemical chain reaction of the fire. There are 3 systems located on board that cover the EDG, Fire Room, and Engine Room. The soak time for Halon is 15 minutes, in addition the space should be ventilated for a minimum of 15 minutes prior to entering. Halon decomposes into two gases when exposed to temperatures in excess of 900 degree. The two gases are Hydrogen Fluoride and Hydrogen Bromide. Halon is 5 times heavier than air. There are two time delays associated with the system. In the EDG the time delay is set for 30 seconds. In the Fireroom and engineroom the time delay is set for 60 seconds. The time delay allows for personnel evacuation and ventilation shutdown.
CO2 System
CO2 fixed flooding is used to extinguish large class Bravo fires typically found in flammable liquid store rooms and paint mixing areas. There are 7 systems located on board. . CO2 is 2 times heavier than air and discharge at a temperature of negative 110 degrees. CO2 smothers the fire by removing oxygen from the compartment thusly making it a extreme personnel hazard.
