A barrier apparatus provides a portable perimeter barrier between people, animals, property or equipment and incoming potential hazards. The apparatus functions as a security or safety device which may be operated by one person in multiple conditions, and may be hand operable or motor-driven. The apparatus is capable of providing alternative electric power distribution and lighting. The apparatus comprises a housing, retractable barrier material, and a mechanical system. The apparatus may include lights, an alarm, and a motion detector. The apparatus may be used with or without a vehicle, and may be carried by a vehicle tow hitch. The apparatus is easily operable by extending the rolls of barrier material from the housing. The apparatus may provide a barrier covering a distance of up to about 170 feet across a road or any area to quickly block or direct the flow of traffic or to establish a perimeter.
