The PPM landscape is evolving rapidly as a result of the growing preference for managing multiple capital investment initiatives from a single, enterprise-wide system. This more centralized approach, and resulting ' single version of the truth ' for project and project portfolio information, provides the transparency of performance needed by ...
During the COVID-19 pandemic, the mask and respirator market rapidly grew, along with counterfeit respirators. [1] NIOSH, on behalf of the Department of Health and Human Services, filed a trademark application on June 17, 2020, for various 42 CFR 84 trademarks, including the N95, allowing NIOSH to enforce rules on counterfeit masks outside of rules defined in 42 CFR 84.

Its units are in parts per million (ppm) for gases and in milligrams per cubic meter (mg/m 3) for particulates such as dust, smoke and mist. The basic formula for converting between ppm and mg/m 3 for gases is ppm = (mg/m^3) * 24.45 / molecular weight. This formula is not applicable to airborne particles.
The respiratory protective devices (RPD) can protect workers only if their protective properties are adequate to the conditions in the workplace.Therefore, specialists have developed criteria for the selection of proper, adequate respirators, including the Assigned Protection Factors (APF) - the decrease of the concentration of harmful substances in the inhaled air, which (is expected) to be ...
