Forensic Engineering Evaluation and Testing of Horizontal Intrusion Protection Equipment for Stand-Up Forklifts
Keywords:Stand-up, forklift, horizontal intrusion, under-ride
AbstractIn 2004, a report issued by the National Institute of Occupational Health and Safety (NIOSH) evaluated a fatal stand-up forklift accident where a warehouse forklift operator was crushed against a rack beam after it intruded into the operator’s compartment. One of the recommendations of the report was that “Manufacturers of stand-up reach forklifts should include vertical framing or posts at the rear corners of their machines, from the operator’s console to the overhead guard, to protect the operator from horizontal components entering the operator’s station 1.” Other published studies have also recognized the risk associated with the hazard of a horizontal rack beam entering the operator’s compartment of a stand-up forklift. It has been previously reported that there have been at least 250 incidences of horizontal intrusion as of June 2008 2. The ANSI B56.1 “Safety Standard for Low Lift and High Lift Trucks” has recognized such guarding as permissible since 1993, and almost all stand-up forklift manufacturers have made such guarding standard equipment. The evaluation that is the subject of this paper is related to the fatal horizontal intrusion incident involving a stand-up lift truck (forklift) operated by a 44-year-old male.
