Environmental Health Training in Emergency Response Conducting Building Assessments

Environmental Health Training in Emergency Response

Conducting Building Assessments

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

Building AssessmentClosing out

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