silica dust Control in small scale building structure demolition operations using good Work Practice guidance
Journal of Physics: Conference Series, 2009Co-Authors: Custodio V Muianga, Carol Rice, Paul SuccopAbstract:Work Practices can influence exposure, especially in small-scale operations conducted by mobile Work crews. This study evaluated the use of information on good Work Practice in Control guidance sheets adapted from UK Silica Essentials guidance sheets by trained Workers and supervisors employed in small-scale concrete and masonry demolition operations. A one-page employee silica task-based Control guidance sheet for each of four demolition tasks and multiple-page silica Control guidance for supervisors were developed. Interactive, hands-on Worker training on these task-based good Work Practice Controls was developed. Training was presented to 26 participants from two demolition crews. Feedback on the training and task-based good Work Practice Control guidance sheets was elicited. Observations of Work Practices were made before and after training. Participants indicated gains in knowledge and checklists were used to document skill attainment. The quality of the training and usefulness of the material/skills was rated high by trainees. Increased use of water to suppress dust and wet cleaning methods on the job were documented following the training. Additional follow-up after training is required to determine long-term impact on sustained changes in Work Practices, and to evaluate the need for refresher training.

Evaluation of the Effectiveness of Hygenall © Leadoff TM Foaming Soap in Reducing Lead on Workers’ Hands and the Uptake of Lead on Bridge Painting Projects
2020Co-Authors: Kevin Guth, Marie Bourgeois, Giffe T. Johnson, Raymond D. HarbisonAbstract:Although considerable research has been conducted regarding airborne lead exposures during lead paint removal, little data has been collected measuring the lead concentration on Workers’ hands in the construction industry. As a result, there are gaps in our understanding of the effectiveness of a standard Work Practice Control (handwashing) in the prevention and Control of elevated blood lead levels (BLLs) in the Workplace. The primary objective of this study was to assess if a National Institute for Occupational Safety and Health (NIOSH) formulation intended to remove lead from skin (Hygenall© LeadoffTM Foaming Soap) is more effective than a commonly used soap in the industrial painting industry (Zep Cherry Bomb Soap) in reducing the concentration of lead on Workers’ hands after exposure. A secondary aim was to assess if using LeadoffTM Foaming Soap during handwashing reduces Worker uptake of lead on bridge painting projects. We evaluated hand wipe, air sample and blood lead level data collected by two industrial bridge painting contractors. Airborne exposures ranged from 350 μg/m3 to 19,700 μg/m3. The geometric mean lead concentration remaining on Workers’ hands after using Zep Cherry Bomb Soap was 77 μg per hand wipe compared with 61 μg per hand wipe after use of LeadoffTM Foaming Soap for all Work classifications. The geometric lead concentration on Workers’ hands decreased by 16 μg/hand wipe for all Work classifications combined after using LeadoffTM Foaming Soap—a decrease of 21%. The use of Hygenall LeadoffTM Foaming Soap reduced the maximum lead concentration on Workers’ hands by 85%. The geometric mean BLL for all Work classifications was 12.1 μg/dl before the use of LeadoffTM. After two months of airborne exposure and use of LeadoffTM Foaming Soap at breaks and at the end of the Workday, the geometric mean BLL for all Work classifications increased to 18.1 μg/dl. Worker BLLs increased despite the reduction in the concentration of lead measured on Workers’ hands—most likely a result of ineffective inhalation exposure Controls. We found that the LeadoffTM Foaming Soap was more effective in removing lead from Workers’ hands than Zep Cherry Bomb.
