Recommendation 7: Safety Case specification of TSR and escape

In connection with the above the Safety Case should specify the following:- In respect of the TSR- — its function — the conditions which constitute its integrity — the conditions for integrity of its supporting structure — the events in which and the period for which it is to maintain its integrity (paras 19.157-158). In respect of escape routes to the TSR and from the TSR to the embarkation points- — the conditions which constitute their passability — the conditions for integrity of their supporting structure — the events in which and the periods for which they are to maintain their passability (provided that for each location on the platform there should be a minimum of two escape routes to the TSR, at least one of which should remain passable for the period) (para 19.164). In respect of embarkation points and lifeboats- — the number and location — the conditions for their integrity and that of their supporting structure — the events in which and the periods for which they are to maintain their integrity — the minimum complement for the TSR (para 19.164).
