Abstract:
The concept of “research to practice” informs us that a successful control intervention does not just remove dust or reduce noise in the laboratory or during its first implementation onto a construction site. It is also used regularly, maintained and becomes part of the normal work process. This type of control also requires on-going management support and worker acceptance to be effective.
Silica dust, generated by demolition and concrete finishing operations, can be controlled on construction sites through the effective use of engineering controls, such as using water and local exhaust ventilation on tools. Nevertheless, these controls are not used on most worksites. Noise has been a persistent and well-documented hazard in construction. However, we have yet to gain a foothold in the effective control of noise exposures to construction workers.
The successful use of controls on construction sites is determined by factors which can be identified so that the effective use of engineering and/or administrative controls in construction can become sustainable. This project partners with demolition and concrete contractors, unions and tool manufacturers to identify and overcome obstacles to the successful implementation of controls for noise and silica dust on construction sites. The focus for the control of dust and silica exposures will be on implementation of local exhaust ventilation and water suppression for powered hand tools and demolition equipment. Efforts to reduce the noise exposures generated by these tools will focus on implementing a “Buy-Quiet” and a “Noise Perimeter Zone” approach.
