Abstract
Our interest in respiratory protective devices began at a meeting of the Interdepartmental Committee on Pest Control in 1949, when it was found that no suitable device was available for protection against organic phosphorus insecticides that were then being used on an experimental basis. In cooperation with manufacturers, all the absorbing materials and filters then available were tested to determine the type of unit that would remove the toxic vapors of these compounds, as well as chlorinated hydrocarbons, from sprays, mists, and dusts.
