One of the most common questions we hear from safety professionals is: "How often does OSHA require air sampling?" The honest answer is that it depends, and that answer alone can make or break a compliance program.

Novel species of fungi described in this study include those from various countries.

In the world of Industrial Hygiene, data is our currency. The decisions we make - whether to implement expensive engineering controls, require respiratory protection, or certify a work area as safe - are only as good as the samples we collect.

As a result of long-term field work in subtropical Texas, USA, three novel genera and three new species are introduced in Pezizomycotina to accommodate new or previously described taxa lacking DNA sequence data.

Respirable crystalline silica (RCS) is one of the most significant occupational hazards in mining. With MSHA’s recent final rule lowering permissible exposure limits (PEL) to 50 µg/m³ (8-h TWA) and introducing an action level of 25 µg/m³, mine operators must now adopt more precise monitoring and analytical strategies.

The U.S. Environmental Protection Agency (EPA) has rolled out a critical new Toxic Substances Control Act (TSCA) compliance requirement for facilities that use Trichloroethylene (TCE). This update is a game-changer, demanding technical precision and meticulous record-keeping from EHS professionals and Certified Industrial Hygienists (CIHs).

Hexavalent chromium, or Cr6+ is a highly regulated hazard in industrial hygiene with a strict permissible exposure limit (PEL) of just 5 µg/m³ for an 8-hour time-weighted average. This low limit makes meticulous sampling and analysis crucial, but it also means that seemingly small errors can have a big impact.
