A self evaluation procedure was developed for managers and labor personnel to use for the identification and prevention or control of various potential hazards in the work environment. According to the authors, most industries should benefit from the core of basic information provided. Employee centered programs include the setting of specific goals and objectives with program elements designed to meet goals, staffing the program, employee involvement, and budgeting. Recognizing and controlling hazards requires adequate recordkeeping, inspections, priority setting, and employee incentives. Matching employees with job selection and training can be achieved through preplacement examinations, medical followup and surveillance, ergonomic studies, attention to alcohol and drug abuse and the proper use of supervisory personnel. Effectiveness of a program can be measured through objective and subjective measurements and an assessment of relative risk factors.
