Leak impact factor sample 71175
Table 7.24 Sample LIF algorithm
Risk rjariable Scoringprotocol Comments
Spill size Square root offpressure) Spill size is modeled as being a function of(proportiona1 to the square root 00 of
internal pipe pressure
Spread I No differences in dispersion potential are recognized
Product hazard 18 Constant for this pipeline; for comparisons with other pipelines. natural gas = 7,
gasoline= IO
Receptors (general population density) Two variables are used to quantify the receptor of interest (population density);
+(special population areas) seeTable 7.18
Leak detection 1 Constant: no changes along pipeline
Emergency response I Constant: no changes along pipeline

Table 7.24 shows the LIF variables used in the model. Future detection, drain volumes, emergency response, additional
improvements to the analyses could include evaluations of leak receptors, and dispersion potential.
