3108F.2 Hazard Assessment and Risk Analysis
A fire hazard assessment and risk analysis shall be performed, considering the loss of commercial power, earthquake and other relevant events.
A site-specific Fire Protection Assessment shall be prepared by a registered engineer or a competent fire protection professional. The assessment shall consider the hazards and risks identified per Section 3108F.2.1 and shall include, but not be limited to, the elements of pre-fire planning as discussed in Section 9 of API RP 2001 [8.1] and Chapter 19 of ISGOTT [8.2]. MOT operational and training requirements, as related to fire protection, shall be considered (see 2 CCR 2385 [8.3]). The Fire Protection Assessment shall include goals, resources, organization, strategy and tactics, including the following:
- MOT characteristics (e.g., tanker/manifold, product pipelines, etc.)
- Product types and fire scenarios, including products not regulated by the Division that may impact development of fire scenarios
- Possible collateral fire damage to adjacent facilities
- Firefighting capabilities, including availability of water (flow rates and pressure), foam type and associated shelf life, proportioning equipment, and vehicular access
- The selection of appropriate extinguishing agents
- Calculation of water and foam capacities, as applicable, consistent with area coverage requirements
- Coordination of emergency efforts
- Emergency escape routes
- Requirements for fire drills, training of personnel, and the use of equipment
- Life safety
- Rescue for terminal and vessel personnel
- Cooling water for pipelines and valves exposed to the heat
- Contingency planning when supplemental fire support is not available. Mutual aid agreements can apply to water and land based support.
- Consideration of adverse conditions, such as electrical power failure, steam failure, fire pump failure, an earthquake or other damage to the fire water system.
The audit team shall review and field verify the firefighting equipment locations and condition to ensure operability.
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).
