Controlled Atmospheric Chamber
The Controlled Atmospheric Chamber is a key facility for various
types of decontamination testing.
It is a 34m3 LEV facility with temperature and
humidity-controlled inlet air and total loss airflow operation
(i.e. not recirculating).
The chamber can be closed off once airflow is stopped, using gas
impermeable dampers operating over both inlet and outlet vents,
thus rendering the room a sealed test chamber.
The facility allows HSE to work with biological agents,
including those classified up to Hazard Group 2, though wherever
possible bioaerosol work is undertaken using the lowest possible
hazard grouping, including surrogate microorganisms, thus aligning
with COSHH best practice.
