It is commonly admitted that the great majority of industrial accidents are caused directly by specific unsafe acts of persons or exposure to specific mechanical or physical hazards. It is agreed that these causes and the accidents that they create interfere seriously with the quality, volume, and cost of production and are of a preventable nature. There is general agreement, also, that successful methods in accident prevention are similar to those that are used in controlling production and, therefore, that industrial management is well equipped to solve its employee-safety problems.
