HYDROCARBON RELEASES INVESTIGATION READY RECKONER

Use these sheets to help determine the investigation level for hydrocarbon releases.

If necessary, use the Unit Converter to convert field units into the required SI units.

Input data into unprotected cells (RED zeros) in Ready Reckoner or Unit Converter and then press enter to generate the required value.

Use Working Pressure and Hole Diameter and Duration estimates to generate the estimated release Quantity for the hydrocarbon type.

You can also estimate the Quantity in kg in Unit Converter for various scenarios.

Use Quantity and Investigation Criteria to determine Investigation Action.
