For example, school districts employ carpenters to replace glass, ceiling tiles, and doors, and to repair desks, cabinets, and other furniture. Some work in industries which manufacture products made of wood, such as prefabricated houses, boats, and furniture. As in other building trades, the work is active and sometimes strenuous. Prolonged standing, climbing, bending, and kneeling often are necessary. Carpenters risk injury from slips or falls, from contact 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. Seven of every ten work for contractors who build, remodel, or repair buildings and other structures. Most of the remainder work for manufacturing firms, government agencies, wholesale and retail establishments and schools. About 1 out of 3 is self-employed.
