Stay ahead of the MSHA silica rule—with data that drives action
Real-time exposure alerts. Task-level insights. SEG-level risk visibility. APT helps you move from “we think” to “we know.”
The new rule is here.
So are the risks.
The updated MSHA standard cuts the permissible exposure limit (PEL) for respirable crystalline silica in half and mandates corrective action when exposures exceed the action level. But outdated sampling methods and unclear data make compliance harder than ever.
Frequent re-sampling
Filter-based methods delay results and don’t pinpoint sources.
Inability to identify high-risk tasks or SEGs
Makes it hard to deploy targeted engineering controls.
Noncompliance risk
Failure to meet the new PEL or action level can trigger citations, fines, or shutdowns.
Data gaps
Lack of continuous, defensible data puts your industrial hygiene program at risk.
Cost drivers turned savings
Sites spend millions of dollars per year to manage dust and silica without the right data—from $20K–$50K per sampling run up to $8K per MSHA citation (plus legal fees).
APT helps teams turn those costs into measurable savings:

Case study
A leading aggregates producer used APT’s LEAP™ platform to deploy 10 dust monitors, automate real-time alerts, and proactively respond to community dust complaints—backed by defensible, season-spanning exposure data.
APT’s technology helps our facilities pinpoint our silica exposures, reducing our risks and improving operational efficiencies in real time.

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.
