1.1 Identifying hazards

Contextual description: It is not possible to define safe behaviour without first identifying all of the hazards associated with the RAS operation. Although it is not possible to prove that all hazards have been correctly identified, it is important to demonstrate there is sufficient confidence in the completeness and correctness of the hazards for the defined operation of the RAS through the approach taken to hazard identification.

Practical guidance:  In many cases standard hazard identification techniques such as structured brainstorms or checklists will be applicable, particularly in a closed environment where the RAS is replacing a human in well-understood tasks. More guidance will be required in open environments and where the RAS is introducing novel behaviour.
