Drywall and ceiling tile installers hang wallboards to walls and ceilings inside buildings. Tapers prepare the wallboards for painting, using tape and other materials. Many workers do both installing and taping. Drywall and ceiling tile installers and tapers spend most of the day standing, bending, or stretching. Injuries include falls from ladders or stilts, cuts from sharp tools, and muscle strains from lifting heavy materials. The work also can be dusty, irritating the skin, eyes, and lungs.
