A personal safety system for lifting material or supporting person therefrom includes a base and a mast rotatably coupled to the base. The mast has a plurality of mast sections that telescope relative to each other along an axis such that the mast is movable into and between a lowered configuration and an extended configuration. A jib is coupled to the mast and a cable is coupled to the jib such that a cable is configured to couple to the material or the person such that the system is capable of lifting the material or supporting the person. An attachment device coupled to the base is configured to permit a vehicle to couple to the system via the attachment device.
