Crystalline Silica Monitoring in San Diego
Respirable crystalline silica is generated when workers cut, grind, drill, or crush materials containing silica — including concrete, brick, stone, mortar, and sand. Prolonged exposure to respirable crystalline silica can cause silicosis, lung cancer, and other serious respiratory diseases.
When is Silica Monitoring Needed?
- Construction activities involving cutting, grinding, or drilling concrete, stone, or masonry
- Demolition projects generating concrete dust
- Countertop fabrication (natural and engineered stone)
- Sand blasting and abrasive blasting operations
- Tunneling and mining operations
- Compliance with Cal/OSHA Table 1 requirements or when exposure assessment is required under 8 CCR 1532.3
Our Crystalline Silica Monitoring Services Include:
- Personal breathing zone air sampling using calibrated sampling pumps and cyclone samplers
- Area air monitoring to assess general workplace exposure levels
- Laboratory analysis for respirable crystalline silica (quartz) via NIOSH Method 7500 (XRD) or 7602 (IR)
- Comparison of results to Cal/OSHA PEL (25 µg/m³ TWA) and Action Level
- Written exposure assessment report with findings and recommendations
- Guidance on engineering controls, work practices, and respiratory protection
- Support for written Silica Exposure Control Plans as required by regulation
Service Area: San Diego, Los Angeles, Orange County, and throughout California.
