Respiratory protective devices for use against chemical, biological, radiological and nuclear (CBRN) agents - Self-contained open-circuit compressed air breathing apparatus incorporating a hood for escape. Specification Ingestion-build-58320 different test methods1 Scope This British Standard specifies requirements for self contained open circuit compressed air breathing apparatus incorporating a hood, intended to be used only during escape by emergency responders (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
