The study was conducted to assess the efficacy of an assistive tool to reduce the physical exposures of the ceiling installation task. Based on the idea of using a ‘deadman’ (long narrow piece of panel) to help hold the panels on the ceiling while installing them, a prototype tool was fabricated that could be placed on its own while supporting the ceiling. This tool, which was introduced to the drywall foremen and ceiling installers at a construction site, was implemented as an intervention for the ceiling installation process. To evaluate the efficacy of this tool for exposure reduction, the researcher collected quantitative exposure data (PATH) and qualitative data at the baseline and intervention phases. The data at the two time periods were compared to evaluate any change in the exposure with use of the tool. Results showed that physical exposures (such as overhead arm, postures, heavy load handling, load handling while holding the panels with arms raised while being on a ladder) were reduced while using the tool at the intervention phase. Reduction of physical ergonomic exposures by the use of the prototype tool is evident in the result while the tool itself was a better version of the ‘deadman’ regarding its easy usage and self-supporting structure i.e., the installers need not hold it under the ceiling.
