Inside, they are frequently exposed to drafts, changing temperature, and loud noise. Outside, they may work in bad weather, in rain or snow, or in wet or icy areas. Both inside and outside, the mechanics are frequently exposed to irritation or discomfort from dust, heat, fumes, and hard damp floors or surfaces. Mechanics work on parts and systems which are dirty and greasy, and which may be dangerous to operate or repair because of defects. They are frequently exposed to the possibility of receiving cuts, burns, bruises, strains, and electrical shock while repairing, positioning, adjusting, and moving equipment, and are exposed to the possibility of receiving bums and skin irritations from acids, fluids, and lubricants. To reduce the dangers and irritations from the above conditions, the mechanics follow numerous safety procedures and wear equipment such as protective eyeglasses, ear devices, hard hats, hard-toe shoes, respirators, gloves, and clothing. Some of these safety items may be uncomfortable to wear or use and may be worn or used for long periods.

They frequently lift and carry items weighing up to about 18 kilograms (40 pounds) and lift heavier items using jacks, hoists, or helpers.
