Also, many firms have automated inspection with the help of advanced vision systems, using machinery installed at one or several points in the production process. The inspectors in these firms generally are trained to operate this equipment. Working conditions vary from industry to industry. Most remain at one work station, but some travel from place to place to do inspections. Some may have to lift heavy objects.
Some inspectors work evenings, nights, or weekends.
In these cases, shift assignments generally are made on the basis of seniority. Overtime may be required to meet production goals. Employment Inspectors, testers, and graders held about 654,000 jobs in 1994. More than 3 out of 4 worked in manufacturing industries, including industrial machinery and equipment, motor vehicles and equipment, primary and fabricated metals industries, electronic components and accessories, textiles, apparel, and aircraft and parts. Others worked in temporary help services, communications and utilities, wholesale trade, engineering and management services, and government agencies.
