Performance test of technical cleanroom clothing systems

The work presented in this paper deals with aseptic cleanroom clothing systems performance and gowning procedures. The study had the purpose of evaluating the inert and viable airborne particle concentration shed by personnel when gowning a complete cleanroom clothing system suitable for aseptic operations at different washing, drying, sterilization (WDS) cycles. The tests procedure consisted of a normal working activity carried out in a stainless steel body box test rig. Inert and viable airborne contamination has been monitored continuously and in parallel throughout all experimental tests following aseptic procedures during the sampling task. Results have shown how WDS cycles, clothing size and personnel activity may influence the particle content shed by personnel and therefore the air cleanliness of an environment. Personnel working in clean environments might be aware of the importance of gowning system clothing and their procedures as well as the importance of training in operational behaviors in aseptic environments.
