PDC 413

Assessing Inhalation Hazards During an Emergency Response





intermediate | Credits: 8 CM Credit Hours / 0.8 CEU / 0.5 CMP
Sunday, May 22 | 8:00 AM – 5:00 PM
Limit: 60


Exposure Assessment Strategies, Hazardous Chemicals, Incident Preparedness and Response



Catastrophic events involving hazardous chemicals often result in a greater potential for inhalation exposures for responding workers and unsuspecting off-site receptors. The industrial hygienist has a critical role in the recognition, evaluation, and control of inhalation exposures during the subsequent response and mitigation activities. This interactive PDC will present strategies for the quantitative assessment of chemical hazards that are anticipated during emergency situations for the purpose of determining human health risks. Real-time air monitoring instrumentation and integrated air sampling methodologies will be discussed along with predictive air dispersion modeling capabilities. A brief review of the applicable exposure guidelines and standards will be presented. Actual experiences of professionals responding to multiple emergency situations will be shared. The presenters will describe aspects of hazard recognition, evaluation, and control during an emergency response. The panel of professionals will examine the types of resources called on by the industry sector to assess human health risks during an emergency response. A hands-on group mock scenario will give the participants the opportunity to implement evaluation strategies and generate valuable discussion.

Learning Aids

Participants must bring a laptop OR tablet/iPad, smartphone (Blackberry, Android, iPhone).

Value Added

Presenters will share lessons-learned on overcoming challenges encountered during emergency events: extreme weather, changing site conditions, complex chemical hazards, and poor communication systems, to name a few.


Upon completion, participants will be able to:

  • Identify the potential inhalation exposure hazards related to unexpected events.
  • Determine the applicable exposure guidelines and regulatory standards.
  • Select the proper air monitoring / sampling equipment and effectively characterize exposures.
  • Utilize predictive air dispersion modeling information to assess potential risks to affected on-site workers and off-site receptors.
  • Implement air monitoring / sampling strategies to evaluate inhalation exposures during an emergency event.
  • Establish safe work zones for affected workers and select appropriate PPE for use during mitigation activities.
  • Apply industrial hygiene principles to assess inhalation exposures for workers and community receptors and determine potential risks.
  • Discuss the exposure assessment strategies implemented at multiple different emergency events.


  • Introduce the main components to consider during the evaluation of inhalation hazards during an emergency response
