Monitoring for PELs, TLVs of Toxic/Combustible Gases

The TLV for chemical substances is defined as a concentration in air, typically for inhalation or skin exposure. Its units are in parts per million (ppm) for gases and in milligrams per cubic meter (mg/m ) for particulates such as dust, smoke and mist. The basic formula for converting between ppm and mg/m for gases is ppm = (mg/m^3) * 24.45 / molecular weight. This formula is not applicable to airborne particles.
