If tests indicate a dangerous atmosphere, you must NOT enter the space until it is thoroughly ventilated and subsequent tests indicate the air is safe to breathe.
Test the atmosphere in the following order: (1) for oxygen, (2) for combustible gases, and then (3) for toxic gases and vapors.2 The testing results -- the actual test concentrations --must be recorded on the permit near the lev-els identified for safe entry. Duration of Testing For each test … NOTE 3 Where an explosive gas atmosphere and a combustible dust atmosphere are, or can be, present at the same time, the simultaneous presence of both often warrants additional protective measures. Additional guidance on the use of Ex Equipment in hybrid mixtures (mixture of a flammable gas or vapour with a combustible dust or combustible flyings) is given in IEC 60079-14.
Characterizing atmospheres beyond the Solar System is now within reach. ... of paradigm-shifting astronomical discoveries overshadowed by the deepest financial ... All that remains is the light of the exoplanet and its atmosphere (if it exists). ... Solar System and motivates theoreticians to test their tools in unfamiliar territory.
Thus, atmospheres might be determined, mapped, and measured through quantitative methods tracing emotional, cognitive, and neurophysiological responses of individuals to spatial conditions.The exploratory study illustrated attempts to test this hypothesis, by undertaking an experiment informed by phenomenological and embodied cognition theories.
