    If a clean room needs to be shut down it needs to be completely de-contaminated after it is put back in commission. Nothing more then a TON of cleaning and verifying that it is clean.

    What you are looking for is ISO Standard 14644-4 Here is a link to it.

    The premise of ventilation is that the OA is clean or of sufficient quality to be used for dilution. Traditional ventilation is somewhat being threatened by the fact that the EPA is changing the requirements for outdoor air quality which is creating non-attainment zones in what is now becoming a significant portion of the country. That means that buildings in those areas will need to clean up the OA before they bring it into the building.

    Epa is raising the allowable limits on radioactive particulates thanks to the Japanese nuke meltdown. So far they have detected the stuff in something like 27 states. Suddenly it is safer to breathe I guess.
