H allows this respirator to be used for protection against a mixture of contaminants that are present simultaneously or alternately against one contaminant then another using the same cartridges or filters if the mixture meets the following conditions e The cartridge filter must be approved for all contaminants present e NIOSH permits mixing of the following contaminants Organic vapors sulfur dioxide chlorine ammonia methylamine chlorine dioxide hydro gen sulfide and hydrogen chloride e Particulates can be mixed with any other particulate or any gas or vapor for which the cartridge is approved e Contaminants present simultaneously must be below IDLH levels for the specific contaminants If anyone contaminant in the mixture exceeds the IDLH concentration then the entire mixture must be treated as IDLH and the respirator cannot be used except for escape from particulates with the appropriate filter e Mersorb and Mersorb P100 cartridges can be used against a mixture of chlorine and mercury that are both present simultaneously but can not be used if alternating between mercury contaminated atmospheres and chlorine contaminated atmospheres Mersorb and Mersorb P100 respirators utilize an end of service life indi cator for use against metallic mercury vapor The small area at the cen ter of the inlet surface of each Mersorb cartridge and the band around the side of each Mersorb P100 cartridge consists of chemically treated
