Particulates such as dusts, mists, and fumes could be sampled by a cassette and membrane filter, generally by using a personal high-flow pump. Vapors and gases could be sampled by adsorbent tubes with media like activated charcoal, silica gel, alumina, or certain polymers by using calibrated pumps. Oxygen-deficiency could be sampled using an oxygen meter. Flammable atmospheres, such as hydrocarbon vapors, could be sampled using a combustible gas meter.
