Behavioral measures as means of reducing workplace hazards were discussed. The need for hazard control in the workplace was considered. The role of behavioral measures in occupational hazard control was reviewed. The characteristics of eight broad classes of hazard control behaviors were described. Directive methods for shaping self protective action in the workplace were reviewed. These were based largely on behavioral management strategies. Behavioral managements could be regarded as consisting of four key components: assessment, formulation of objectives, applying behavior change methods, and evaluation. Examples of behavioral management approaches were given. Nondirective approaches for shaping self protective actions were reviewed. These were based on changing attitudes, increasing knowledge, and heightening awareness through incentive plans and communication and information programs. New industrial trends that have implications for worker self protection were described. These included increasing use of robots on shop floors and video display terminals in offices, the increasing number of women entering the work force, the increasing number of white collar jobs, and eliminating the mandatory retirement age. The author concludes that these developments may redefine and sharpen issues of worker self protection against occupational hazards.
