Dennis B. Brickman and Ralph L. Barnett

The flexible flight auger gives rise to a new set of hazards and risks without fulfilling its promise of eliminating the amputation hazards. Failure modes of the auger are discussed.


Auger Elevator: Failure Modes and Effects
Triodyne Safety Brief
v. 9 #2 (January 1992)

Dennis B. Brickman and Ralph L. Barnett

Analysis of a fatal auger elevator accident reviews a number of fundamental failure modes in order to determine the cause of the accident. Analysis showed that the accident was caused by unusual misuse of the product. Known safety control concepts do not preclude such unforeseeable events.


Small Agricultural Tractor ROPS: New Operator Protective Zone
Triodyne Safety Brief
v. 7 #4 (August 1992)

William G. Switalski and Edward A. Fritz

A literature search attempts to identify all Operator Protective Zones (OPZ) ever utilized in the world, in order to determine whether published information exists to define a more compact OPZ than those of current SAE/ASAE standards. The researchers conclude that the OPZ upon which the current standards are based is the only substantiated zone available for possible application to small agricultural tractors.


On the Safety of Agricultural Disk Mowers
ASME DE v.83
, in Design Engineering Technical Conference 1995. New York, American Society of Mechanical Engineers, 1995, pp. 107-113

Dennis B. Brickman

A thrown object test protocol was developed and performed, based on agricultural rotary mower safety standards, to analyze the safety of an agricultural disk mower. Test results are analyzed, and the Safety Hierarchy is used to explore safety strategies for mitigating the thrown object danger.
