The TLV® includes a table for estimating HAL from F and D originating from data in Latko et al.

American Industrial Hygiene Association Journal, 58(4):278-285, 1997) and post hoc adjustments that include extrapolations outside of the data range. Multimedia video task analysis determined D for two additional jobs from Latko's study not in the original data-set, and a new nonlinear regression equation was developed to better fit the data and create a more accurate table.

The COV-DIS is a survey instrument designed dot measure the impact of the novel coronavirus (COVID-19) pandemic on the lives of persons with disabilities. Those with disabilities (e.g. deaf and hard of hearing, blind and visually impaired, physically disabled) may be particularly vulnerable to complications of COVID-19 and to difficulties in daily living related to government mandated lock-down measures. The COV-DIS includes items related to the following domains: general health, depressive symptoms, social isolation, COVID-19 infection/exposure, daily activities, access to medical care, employment and financial impact, and transportation, and information access. This survey is freely and publicly available at no cost.

Approximately 33 percent of U.S. adults are affected by musculoskeletal signs or symptoms, including limitation of motion or pain in a joint or extremity which are the leading cause of disability among individuals of working age (18 to 64 years of age). Annual costs of MSDs are estimated to be: • $15-$20 billion in workers compensation costs alone • $45-$50 billion total when including other expenses

The four horizontal work locations ranged from 13-88 cm in front of the body and were placed at 25 cm intervals. The vertical placement of the horizontal beam was at midthigh, elbow, and midchest height. Subjects drove 25 screws at each tool/work location combination before rating that condition using the Borg 10-point ratio rating scale. The ratings of perceived exertion increased with increasing horizontal distance from the body. When tool shape was not considered, the perceived exertion was virtually equal for driving screws at midthigh or elbow height. The ratings at midchest height were significantly higher than elbow and midthigh height. When tool shape was taken into account, subjects perceived less exertion driving screws with the pistol-shaped tool at midthigh height. The in-line and right-angle tools had the lowest ratings of perceived exertion for driving screws at elbow and midchest height.

To do this, safety and health professionals rely on a variety of information sources to identify and prioritize opportunities for ergonomic interventions. As part of a 4-year project to reduce overexertion injuries in the service parts division of a major auto maker, a study was performed in 19 parts distribution centers to evaluate the contributions of the following information sources in identifying specific high-risk work locations and activities: (1) archival medical/injury records, (2) identification of "problem tasks" by plant-based ergonomic committees, (3) facility walk-throughs by experienced ergonomists, and (4) detailed ergonomic job analyses. Archival records were not particularly useful in identifying high-risk activities because essential exposure information (e.g., t...
