ABSTRACT:
A method and device has been developed to enable emergency responders to maintain and communicate their orientation relative to a fire building or other emergency incident area as they work in and around it. The device is a specialized compass enhancement providing a standalone unit that each responder can carry. The device has a multipart structure including: (1) an underlying base is a simple compass that the responder orients to north. (2) A bezel rotatable around the simple compass is preferably square in shape and represents the building or incident area and is labeled with NIMS standardized ABCD designations. (3) An optional rotatable pointer can be independently positioned to indicate a direction to be remembered such as the direction in which the responder entered the incident area. All of the parts can be synchronized among users at any time by radioing simple verbal descriptions of the rotational setting(s).
