Respiratory protective devices for use against chemical, biological, radiological and nuclear (CBRN) agents - Air-purifying devices incorporating a hood for escape. Specification Ingestion-build-48183 Immunity measurements are based upon1 Scope This British Standard specifies the requirements for air purifying devices incorporating a hood intended to be used only during escape by emergency responders (e. g. re, ambulance, police) and adult civilians from areas contaminated by chemical, biological, radiological and nuclear (CBRN) agents. This British Standard is applicable to Type ES CBRN devices. Type ES CBRN devices provide resistance to liquid and gaseous chemical agent permeation
