Exercise 8.2

a) Carry out HFSP calculations for one of the following hypothetical hazardous facilities – assume you have to work with the information which you have at hand in this training course. Use the HFSP calculation forms and refer to the Consent Status Tables in Module 4 to decide on the likely consent status of the hazardous facility in question. Assume that the assessment is for the storage (not use) of the substances in question.
