B1a. Respirable Crystalline Silica (RCS) in Polymer Concrete Manufacturing
A multi-site polymer concrete manufacturer determined they were exceeding the respirable crystalline silica (RCS) permissible exposure limit and needed solutions to reduce exposure. This presentation will focus on the exposure problem statement, job tasks leading to exposure, and success with reducing exposure levels. Details will include: a) the process to determine adequate engineering controls; b) the hierarchy of controls; and c) the sampling strategy. Worker exposure to RCS was reduced within the facility.

A bentonite-based material and water mixture is used as a drilling fluid during directional drilling activities. Bentonite-based material contains varying amounts of respirable crystalline silica. The activity of dumping bags into a hopper is not encompassed within OSHA's Table 1 within the Respirable Crystalline Silica Standard (1926.1153). This case study shows: a) the exposure assessments performed for different volumes of bentonite; b) the control methods used to limit exposure to RCS; and c) how to use this data for controlling similar operations.
