Respirable crystalline silica is created whenever you cut, grind, drill, or crush materials like concrete, stone, brick, and mortar — which puts it squarely in the path of a lot of construction and masonry work. When workers are exposed above the level OSHA sets, the respirable crystalline silica standard requires a written Exposure Control Plan.
A silica ECP generally has to identify:
The tasks that create silica exposure in your specific operations.
The engineering controls and work practices used for each — often the water-delivery or dust-collection methods tied to specific tools.
Respiratory protection where controls alone aren't enough.
Housekeeping practices that limit dust accumulation.
A designated competent person to implement the plan.
Because silica shows up in such common tasks, this is a plan many contractors need but don't realize they're missing until a client or reviewer asks for it.
