John Neiger
John Neiger was a founding director of Envair Limited in 1972, becoming Chairman from 1990 until 2004. He is now a consultant to that company and is also pursuing a second career in technical writing. Envair specialises in the design and construction of a wide range of clean air and containment facilities including hospital pharmacy aseptic suites and negative pressure isolators for the safe preparation of cytotoxic drugs.
John sits on various standards committees including BSI CH 101, which concerns itself with microbiological safety cabinets, and BSI LBI 30, which concerns itself with the new ISO 14644 series of international cleanroom standards. He is also on two international working groups: WG 6, which assembled ISO 14644-6: Vocabulary, and WG 7, which developed ISO 14644-7: Separative devices, the standard covering isolators. He was an active co-editor under Brian Midcalf of Pharmaceutical Isolators, which was published in May 2004. John now edits the S2C2 Cleanroom Monitor — the technical newsletter for the Scottish Society for Contamination Control.
John has presented papers in a number of countries promoting the use of negative pressure isolators rather than open-fronted safety cabinets for cytotoxic work. In the debate regarding positive or negative pressure isolators for cytotoxics, he stands for negative isolators.
