Modern agriculture depends on mechanization, but these large machines can present hazards, especially when combined with long hours and solitary working conditions. Manufacturers strive to build equipment that is safe to operate and maintain by following industry-wide safety standards. Using injury data, field tests, and laboratory analysis, safety specialists study the use, and possible misuse, of agricultural machines, and help ensure the equipment’s compliance with safety regulations. To keep informed of new standards, they often participate in the organizations that develop these guidelines. Safety specialists and engineers are employed by equipment manufacturers and government agencies, and they often work as consultants.
