Preventing Injuries from Installing Drywall
Workers who handle drywall sheets are at high risk of overexertion and fall injuries. NIOSH research has led to recommendations for preventing these injuries.
NIOSH research [Chiou et al. 2000] found that the two main causes of injuries to drywall installers and carpenters are overexertion (37%) and falls (32%). These injuries frequently occur while workers are installing drywall sheets [WDLI 2002]. A NIOSH survey of drywall installers and carpenters found that workers believed their biggest risk of physical stress was from lifting, carrying, or holding drywall [Pan et al. 1999]. The State of Washington [WDLI 2002] also found that overexertion hazards were a major source of injury to drywall installers. Overexertion hazards were responsible for the greatest proportion of costs for medical care, impairment, and pay-loss days in Washington State [Lipscomb et al. 2000]. Installing drywall can cause overexertion injuries, usually to the back, because drywall sheets are heavy and bulky. Injuries include strains, sprains, or tears and can range from minor to severe.
Workers should be aware that drywall sheets vary by thickness and weight: some sheets weigh less than 55 pounds, and others weigh more than 120 pounds. NIOSH has studied the relationship between lifting heavy objects and subsequent back pain. The NIOSH Lifting Equation  (which is a formula for judging the risk of lifting heavy objects by the likelihood of subsequent back pain) suggests that lifting heavy objects such as drywall poses a high risk of back pain.
Falls are an additional major cause of injury during drywall installation [Lipscomb et al. 2000]. Fall-related injuries for drywall installers and carpenters can be caused by losing balance as a result of lifting, carrying, or holding heavy and bulky drywall sheets, or by other events, such as falls to a lower level from stairs. Poor lighting and a wet or slippery work floor, along with obstruction of peripheral vision due to handling oversized drywall sheets, can also place drywall installers and carpenters at risk of slip and fall incidents [Pan and Chiou 1999b].
In addition, many workers do not have enough hand grip strength to install drywall without risk of overexertion injury [Pan and Chiou 1999a]. Cold and wet conditions can make it more difficult. Even if a worker has good hand and body strength and uses good installation techniques, continued installation by hand can lead to significant overexertion injuries and loss of balance [Pan et al. 2003].
