our ventilation contractors (we are a hospital) are stating that the air quality in theatres, haematology and other intensive care areas should be measured and tested on a regular basis, according to the HTM.
We regular change the high efficiency filters and ensure we have correct air flows and pressures. I cant find anything specific regarding testing air quality - does any one have further experiences / information of this. The test are appear to be similar to passive sampling.
