NIOSH Program Portfolio



NORA Construction Sector Strategic Goals

Goal 5.0: Reduce silica exposures and future silica-related health risks among construction workers by increasing the availability and use of silica dust controls and practices for tasks associated with important exposures.

Intermediate Goal 5.5: Evaluate hazard and exposure assessment research gaps associated with silica in construction

Research Goals
Research Goal Number Goal Description Status
5.5.1 Reactive species hazard component - Support research to improve understanding of health effects and field exposures associated with mixed exposures to silica particulates co-generated with metal exposures
5.5.2 Exposure assessment component Support research to improve sampling methods to support the ability to reliably and accurately measure respirable crystalline silica levels at concentrations below the current NIOSH REL of 0.05 mg/m3.
Respirable silica measurements with high flow rate samplers
