• Description:
  The overall aim of the study is to develop and evaluate a new application of existing ventilation technology to decrease exposure to respirable crystalline silica for cut-offing sawing and conforming to specific construction needs. The proposed control technology would provide local exhaust ventilation protection for workers sawing or working in close proximity to this operation. The evaluation of this new control approach will focus on collection efficiency, applicability for highway construction, and cost efficiency. The first objective is to compare the effectiveness of the respirable silica dust control using the new technology to traditional dry and wet methods. The second objective is to identify the applicability of the proposed technology, as demonstrated during actual construction activities. Using actual field data will allow rigorous assessment of the proposed design in practice. The third objective is to compare managerial information such as relative implementation cost, maintenance cost, supplementary equipment cost, and labor costs. The purpose for comparing managerial data is to determine if the new technology would be comparable or more cost effective than wet methods. [Description provided by NIOSH]
