Building Assessment Objectives
• Know why environmental health assessments are conducted in buildings
• Identify building components and function• Develop an awareness of building assessment
processes, specific response issues, and close-out needs
• Introduce concept of building-related public health hazard and how it plays into building re-occupancy and recovery decisions
Building Assessment Purpose
• Assess impact to building function• Identify building-related public health hazards• Reduce or remove building-related public
health hazards
Building AssessmentThe Why
• Why does a building exist?
• Physiological needs• Psychological needs• Must evaluate
components holistically, not individually
Building AssessmentBuilding Components

Building AssessmentResponse Issues
• Team safety• Situational awareness• Know the building,
contents and hazards• Equipment needs/use• Communication/contact
needs• Information sharing
Building AssessmentRe-occupancy and Recovery
• A 3-step assessment process• Chemical, physical or
biological hazard present in the building?
• Does a pathway exist to transport the hazard to the occupant?
• If so, can the exposure be quantified?

A few things about mold…Take home points:• A visual walk through will give you all the
information you need– Look for mold growth and water damage
• Find moisture source(s) and eliminate• Remove mold growth
– Porous surfaces? Dispose and replace– Impervious surfaces? Clean and disinfect
• Should you sample for mold?– Typically not indicated for emergency response

Building AssessmentRe-occupancy and Recovery
• Public health hazard exists now or in future?
• Does hazard or remediation impact building use?
• Disaster need considerations• Use Recommendations
