Abstract : This patent discloses an apparatus for marking safe areas in an explosive hazard environment such as a minefield. The marking apparatus is carried and deposited into a minefield with explosive cloud forming fuel. When the explosive cloud is set off, mines under the cloud are exploded by the overpressure which simultaneously activates a timer securing the apparatus lid. The lid is pushed away by the spring-like, coiled telescoping members which then fully extend beyond the apparatus housing. The tapered ends of each extended telescoping member bear an electroluminescent light stick for nighttime apparatus and location marking, and a member length flag for daytime marking. Patents. Minefield markers; Land mines; Unexploded ammunition. (edc)
