  • New Workplace Crystalline Silica Requirements Begin this Month

    Silica is a part of the environment, commonly occurring in most soils. Chronic exposure to respirable crystalline silica particulates has long been known to cause restrictive lung disease and complications that can lead to cancer.  Worker exposures to airborne crystalline silica are tightly restricted by California’s Occupational Safety and Health Administration (Cal/OSHA). Federal ...

  • TSI Introduces New AEROTRAK™ 9000 - Nanoparticle Aerosol Monitor

    The AEROTRAK 9000 is an industrial hygiene tool for measuring a new metric for nanoparticle aerosol exposure – lung deposited surface area. Surface area is the measurement metric that research has shown to be highly correlated with exposure and dosing of nanoparticle aerosols. It provides a simple and fast solution for indicating the surface area equivalent dose of particles in the size range of ...
