P was working when a workmate nearby was electrocuted and killed because D (employer) was in breach of safety regulations, and as a result suffered psychiatric illness. CA allowed P’s claim for negligence causing nervous shock saying: (1) D, as an employer, was under a duty of care to P; (2) P suffered harm as a secondary party; and (3) P came within the protection of fear for personal injury as established in EE Caledonia, that a person could sue if he was in the area of actual danger even though he escaped.
