Presentation 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 closeout needs
• Introduce concept of building-related public health hazards and how they play into building reoccupancy and recovery decisions
How Do Disasters Impact Buildings?
• Function affected• Critical services
reduced or eliminated• Acute and chronic
exposure to health risks• Long-term infrastructure
costs
Major Concerns
• Are building-related public health hazards present?
• How do these hazards impact building occupancy or purpose?
• If impacted, how can the hazard be abated to allow reoccupancy and relicensure?
Partners during Building Assessments
• Building owners• Building support services• Administrators • Engineers• Permitting/occupancy authorities
Roles for Environmental Health Staff
• Assessment– Evaluating the indoor environment
(may include sampling and monitoring)• Consultation• Public information• Planning• Liaison activities
Equipment Needs for a Building Assessment
• Standard EH survey tools– Flashlight, camera,
multiuse tool, etc.
• Moisture meter• Basic IAQ meter• Environmental sampling
supplies• PPE and protective
clothing
Safety Concerns for Building Assessment
Activities • Safety of team• Situational awareness• Knowledge of building,
contents, and hazards• Communication/contact
needs
Why Conduct Building Assessments?
• Why does a building exist?• Physiologic needs• Psychologic needs• Must evaluate components
holistically, not individually
Primary Activitiesfor Building Assessments
• Plan the assessment process• Conduct the assessment• Document all information• Communicate findings and
recommendations
Building AssessmentProcess
• 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?

• Public health hazard exists now or in future?
• Does hazard or remediation impact building use?
• Disaster need considerations• Use Recommendations

A Few Things About Mold…
Take-home points:• A visual walkthrough will give you all the
information you need– Look for mold growth and water damage
• Find moisture source(s) and eliminate them• Remove mold growth
– Porous surfaces? Dispose and replace– Impervious surfaces? Clean and disinfect
• Should you sample for mold?– Typically not indicated for emergency response

• Assessment close out with owner/operator• Assessment close out with permitting authority
