3108F.2.3 Cargo Liquid Volatility Ratings and Fire Hazard Classifications (N/E)
The cargo liquid volatility ratings are defined in Table 31F-8-1, as either High (HC) or Low (LC), depending on the flash point.
Fire hazard classifications (Low, Medium or High) are defined in Table 31F-8-2, and are based on the cargo liquid volatility ratings and the sum of all stored and flowing volumes (VT), prior to the emergency shutdown (ESD) system stopping the flow of oil.
The stored (VS) volume is the sum of the HC and LC volumes (VSH and VSL, respectively).
During a leak, a quantity of oil is assumed to spill at the maximum cargo flow rate until the ESD is fully effective. The ESD valve closure time shall conform with 2 CCR 2380 [8.3]. The flowing volume (VF), calculated in Equation (1-1), is the sum of the HC and LC liquid volumes (VFH and VFL, respectively).
