Stay compliant with MSHA's new silica standard

Understand if you're compliant, pinpoint sources of exposure, and put effective controls in place.

Measure silica exposure with personal monitors

Attach dust monitors to your workers to measure silica exposure.

Use data to stay within MSHA's new silica limits

Quickly see if you're compliant, and how you can reduce silica exposure.


No upfront costs with monitoring as-a-service

Buying your own sensors comes with upfront costs, takes time to set up, and requires ongoing maintenance. Let us take the hardware off your plate: Sensors, setup, and maintenance are included in your contract.

Data quality

Independently tested and validated air quality data

We’ve partnered with AQ-SPEC and the EPA to guarantee reliable air quality data.

With shift average samples, we don't know what's contributing to exposures.

But using APT's real-time particulate monitoring, we're able to understand which tasks contribute the most to their exposure, and justify with data where we need to put our money and effort.
