BS 8468-6.1:2020 pdf download.Respiratory protective devices for use against chemical, biological, radiological and nuclear (CBRN) agents Part 6.1: Positive-pressure compressed air line equipment一 Specification.
3.2 biological agent
microorganism that is a pathogen and that has the potential to be used intentionally to cause harm NOTE Human pathogens are relevant to RPD selection.
3.3 radiological agent
substance that emits ionizing radiation and that could be disseminated to cause harm
3.4 nuclear agent
radioactive matter resulting from a nuclear explosion or accidental release from a nuclear facility
3.5 emergency breathing facility (EBF)
facility, as specified by the manufacturer, which comes into operation when the normally operating respiratory protective device is not functioning and provides an adequate level of protection for a period to enable the device wearer to exit the work area, unassisted, to a place of safety
3.6 decontamination
physical and/or chemical process of removing as much contamination as possible from people or equipment
3.7 rapid intervention team (RIT) fitting
system that allows emergency replenishment of breathing air to the self-contained breathing apparatus (SCBA) of disabled or entrapped fire or emergency personnel
4 Requirements
4.1 General
The apparatus shall be positive pressure equipment conforming to:
a) HSEN14593-1;
b) the inward leakage specified in 4.4 and
c) the chemical agent permeation resistance and penetration specified in 4.
Where the apparatus has been designed to be used at temperatures outside those specified in BS EN 14593-1, the manufacturer shall have tested and marked the product appropriately.
NOTE In certain cases, the apparatus may be connected to an emergency breathing facility (6SF conforming to BS 8468.3.1) or to an SCBA (conforming to BS 8468-1).
