After receiving a clarification request regarding the use of eCassandra, guidance has been updated which reinforces the mandatory requirement to use eCassandra. Whilst eCassandra is mandated to use as a Hazard Log Tool, any Delivery Team wishing to use an alternative Hazard Log Tool must be able to demonstrate that the proposed Alternative Acceptable Means of Compliance offers the same level of information/granularity so that visual representation and appropriate audit trail can be clarified and justified against the envisaged accident sequence in comparison to the mandated eCassandra tool. SMP11 and the Hazard Log within the ASEMS Toolkit have been updated to provide the clarification required.
