ASTM E2238-02

1.1 This standard is intended to provide minimum guidelines for the design and placement of evacuation route diagrams (ERDs) used in buildings. It covers the evacuation of building occupants when directed by emergency response authorities in emergencies such as fire, windstorm, earthquake, hazardous materials release, and other events anticipated in the geographic area of the facility.

Note 1 - Evacuation from the facility is not appropriate in all emergencies. For example, a tornado may require sheltering within the building. This diagram standard is intended to be used in conjunction with a facility emergency plan and instructions on appropriate actions from building management, or emergency response authorities, or both.
