The Reality at the Site

Why Traditional Testing Fails in Aggregates

Mobile vans can't reach every quarry. OSHA/MSHA overlap creates compliance complexity most vendors can't handle.

Crushers and Screens at 95–110 dBA

Primary crushers, vibrating screens, and conveyor transfer points generate continuous noise well above OSHA's PEL. 8-hour TWA exposures near crushing are among the highest in any industry.

Multiple Pits, Plants & Portable Crushers

Operations span quarries, sand pits, batch plants, and portable crushers that move between sites. Testing workers across 5–20+ locations requires a solution that travels.

OSHA + MSHA Regulatory Overlap

Quarry operations fall under MSHA 30 CFR Part 62 with different action levels and STS criteria. Operating across both jurisdictions requires dual-standard compliance tracking.

Dust and Vibration Degrade HPD

Concrete dust, aggregate particles, and whole-body vibration affect earplug seal. Workers frequently adjust HPD during shifts — without fit verification, protection is uncertain.

Built for Your Operations

How Soundtrace Fits Into Aggregate Operations

Test at the Pit or Plant

On-site

at any location

Set up in a site trailer or batch plant office. Test quarry workers and truck drivers on-site without pulling them off active operations.

Equipment-Specific Monitoring

Per role

exposure mapping

Dosimeters capture actual TWA by equipment — crusher operator, screen tender, loader driver, batch plant mixer.

OSHA + MSHA in One Dashboard

Dual

standard compliant

Both OSHA 1910.95 and MSHA 30 CFR Part 62 tracked automatically. Different STS criteria, action levels, and reporting — all managed without manual switching.

Multi-Site Central Records

30+

year retention

Every audiogram from every quarry, pit, and plant in one dashboard. Workers who transfer carry their full history. 30+ year digital retention.
