Limitation of use: filters for respiratory protection may be used everywhere, except for some inherent limitation e.g. containers or confined spaces. Principally, the following conditions must be known:
*Type, property and composition of contaminant Oxygen content of the inhalation air must be sufficient [> 17 vol.%]
*Local or national restrictions or conditions should be observed
*For all gases and vapors which may be present in combination with particles [dust, smokes, mist, spray] a combined filter [protection from gases and particles] must be used. The filter recommendations are based on pure substances. With mixtures, by?products, or decomposition products, the impurities must be taken into account. For compounds with a boiling point below 65°C, AX Filters must be used. If the above list mentions a particle filter [e.g. A–P2] for a specific substance, particles are commonly found with the gas or vapor. For information on other substances, please contact one of our MSA subsidiaries.
*Protection against toxic gas and vapors
*Protection class P3 against particles
*Gas filter classes 1 or 2 Single (A, B, E, K, AX) range or - Multiple (AB, ABEK) range
