A

comparable

17
Q

Units of Measure in Consequence Analysis:

The following provide some units of measure of consequence that can be used in an RBI assessment

Safety: ,,,,,,
Cost,,,,,

A
  • e.g. A through E

- low, moderate, and high

18
Q

Units of Measure in Consequence Analysis:

Formula;
loss of fluid =

A

volume of fluid lost × value of fluid per unit volume

19
Q

Flammable Events (Fire and Explosion):

Flammable events can cause damage in two ways:

A

thermal radiation and blast overpressure.

20
Q

Environmental Consequences:

The consequences of environmental damage are best understood by cost. The cost may be calculated as follows;

Formula;
environmental cost =

A

cost for cleanup + fines + other costs

21
Q

Production (Business Interruption) Consequences:

The main production consequences for RBI are ,,,,

financial

22
Q

Production (Business Interruption) Consequences:

Formula;
coat of lost fluid =

Volume released X Value of Fluid Lost

23
Q

Production (Business Interruption) Consequences:

Formula;
Business Interruption =
