Guidance for Filtration and Air-Cleaning Systems to Protect Building Environments for Airborne Chemical, Biological, or Radiological Attacks [open pdf - 781KB]
"This document discusses air-filtration and air-cleaning issues associated with protecting building environments from an airborne chemical, biological, or radiological (CBR) attack. It provides information about issues that should be considered when assessing, installing, and upgrading filtration systems--along with the types of threats that can be addressed by air-filtration and air-cleaning systems. It is intended to provide guidance regarding measures that may be taken to prepare for a potential CBR attack, rather than in response to an actual CBR event. The complex issues regarding response and cleanup in the aftermath of an actual CBR event are situation dependent and are beyond the scope of this guidance document. This is a companion document to the previously released NIOSH document titled 'Guidance for Protecting Building Environments from Airborne Chemical, Biological, or Radiological Attacks.' That document provided a broad array of recommendations for protecting buildings, including physical security, heating, ventilating, and air conditioning (HVAC) system operation, maintenance and training, and filtration. This document gives specific and detailed guidance for one area of concern--filtration and air cleaning."
