Constant handling of massive and bulky drywall sheets creates hazards among drywall installers. Among handling activities, hanging/lifting/carrying were found to be the most hazardous tasks, in a focus group-based study. The objective of this study was to identify the most hazardous activities associated with drywall hanging tasks. A questionnaire was used for the survey. In the questionnaire, three hanging tasks were included: (1) hanging drywall on the ceiling; (2) hanging drywall on the wall (upper half)j and (3) hanging drywall on the wall (lower half). Each of the three tasks was broken into 15-17 constituent activities. Workers were asked to rate the physical stress, fall potential, and risk of being struck by /against an object for these activities, using a seven-point scale (1=hardly at all to 7=a great deal). Sixty carpenters (mean age: 43.7 + / - 9.6 years) with drywall hanging experience (mean experience; 14.1 + / - 8.7 years) from the Carpenters' Union located in Charleston, West Virginia, participated in this study. All the participants completed the survey. Workers rated hanging drywall on the ceiling as the most hazardous task with the mean ratings of 3.65 for physical stress, 3.05 for fall potential, and 3.06 for risk of being struck by/against an object. Among all activities associated with hanging drywall on the ceiling, lifting/carrying/holding drywall in an overhead position was perceived as most stressful (physical stress=5.6), followed by lifting drywall to scaffolding (physical stress=5.3) and carrying drywall to be cut at ground level (physical stress=4.6). The activity of ascending scaffold/stilts before hanging drywall on the ceiling was perceived as having the greatest fall potential (mean=4.6). In addition, lifting drywall to scaffolding was perceived as having the greatest risk of being struck by/against an object. Results from this study provide detailed jnformation to understand hazardous tasks/activities related to drywall hanging as viewed from the workers' perspectives.
