Abstract
We are developing a standard guide that delineates a general approach for
determining the health effects of the occupants of mechanically ventilated
structures exposed to an intentional release of airborne chemical or biological
agents, radiological materials, or an accidental release of toxic industrial
chemicals or materials in or near a building. This Practice/Guide is under the
jurisdiction of ASTM Committee E54 and is the direct responsibility of the
E54.02 Subcommittee. This requires an understanding of building air flow
characteristics and processes to calculate the agent concentration profiles
throughout a structure based on agent fate and transport. Such analysis may take
the form of equations, algorithms, combinations of equations/algorithms, or a
fully developed building model to calculate inter-zonal airflow, contaminant
concentration, and exposure. The standard guide is intended to provide the user
with guiding principles to prepare for, respond to, and/or recover from an
incident involving the overt or covert release of chemical agents, biological
agents, or radioactive materials in or near a building with subsequent dispersion
of that agent throughout the building. Preparation may include threat
vulnerability, protection assessments, and emergency response planning and
training. Response can include decision aides to help first responders. Recovery
would include occupant treatment, forensics, detailed characterization, and
remediation. The guidance will present assessment, analysis, and modeling
options that provide assessments ranging from fast, coarse, and qualitative to
slower, refined, and quantitative.
