They may replace panes of glass, ceiling tiles, and doors, as well as repair desks, cabinets, and other furniture. In manufacturing firms, carpenters may assist in moving or installing machinery. As in other building trades, carpentry work is sometimes strenuous. Prolonged standing, climbing, bending, and kneeling often are necessary. Carpenters risk injury from slips or falls, from working with sharp or rough materials, and from the use of sharp tools and power equipment.
Many carpenters work outdoors.
Some carpenters change employers each time they finish a construction job. Others alternate between working for a contractor and working as contractors themselves on small jobs. Four of every 5 worked for contractors who build, remodel, or repair buildings and other structures. Most of the remainder worked for manufacturing firms, government agencies, wholesale and retail establishments, and schools. About 4 of every 10 were self-employed.
