1.0 ACTIONS AGREED
1.1 PROJECT DEFINITION
1.2 PROCESS DESCRIPTION
1.3 CONTROL PHILOSOPHY
1.4 INCIDENT REVIEW
1.5 INHERENT SHE
Eight GBHE Process SSHE Questions
1) What alternative routes or processes can be used to allow substances or
solvents of lower impact on man and the environment to be considered?
(2) What alternative routes or processes can be used to minimize the
inventories of hazardous substances?
(3) What alternative routes or processes can be used to make process
conditions as benign as possible?
(4) What is the ultimate fate of all substances used in the process that are not
part of the product?
(5) How will processing stages permit internal recycles with minimum or nil
purges?
(6) Can the effluents be further processed to allow a recycle or a better
means of disposal?

(7) What are the consequences on man and the environment of the release of
any of the materials during processing, transport and storage (including
both normal and abnormal conditions)?
(8) What is the impact on capital and operating costs of lower SHE impact
options and higher safety, health or environmental standards?
