Repair technicians work indoors in body shops, which are often noisy. Most shops are well ventilated to disperse dust and paint fumes. Repair technicians sometimes work in awkward and cramped positions, and their work can be physically demanding. Auto body repairers held about 170,900 jobs in 2010. About 61% worked in automotive repair shops, 16% worked for automobile dealers, and another 16% were self-employed.
