scope:

This Specification relates to hazards on Network Rail's controlled infrastructure, access points and other locations (e.g. stations and sidings) on the rail infrastructure.

Hazards listed in the directory shall be of a permanent or semi-permanent nature, not of a temporary nature e.g. a missing drain cover. Such temporary hazards should be notified to Network Rail staff and contractors responsible for their repair.

Purpose

This Specification provides the minimum content of the National Hazard Directory and stipulates the management arrangements, data maintenance and hazard notification process so that contractors and others can be supplied with current details of hazards at site specific locations.
