Guards must be watching monitors. Mr. Graves explained the various types of contractor's theft. Usually on the job site, there are gang boxes or large tool chests, which are on wheels. They should be chained to something permanent. Storage trailers have the potential to be taken.
Office trailers are on wheels as well and can be towed away at any time.
Wheels should be removed once the trailers are placed on the job site. Locks must be sturdy enough to hold with keys held by only one or two people to be of any use. Mr. Barry Tarnef, Loss Control Consultant, Chubb Group of Insurance Companies, discussed cargo crime due to value, portability and marketability. Various controls need to be in place. Physical controls on site include guards and good quality locks on all entrances.
