CM Credit Hours:


This PDC will use research and case studies to review applications of sampling techniques that work for identifying post fire hazards for both residential home fires and urban wildfires. This course will compare and contrast the use of traditional IH sampling and pumps to real-time detection systems equipment. Something as simple as a particle counter can be the best tool used in certain situations. This course goes back to the industrial hygiene fundamental of being the detective behind the detector.

In-person participants: *Registration includes boxed luncheon. **Power strips will not be provided at each attendee's seat; however, charging stations for laptops will be provided in each course room.

Course Outline

• Understanding Why Sampling is Needed
• How to Determine What to Sample
• Potential Airborne Hazards
• Limitations of Using Summa Canisters
• Gas Detection (PID, GASMET, Indoor Air Quality Meter)
• Sampling Plans Using Traditional IH Sampling
• Using an Array of Real-time Detection Systems Equipment
• Understanding Cross Sensitivities (Chemicals, Environmental)
• How Much Data is Enough
• Data Interpretation 

Learning Outcomes

Upon completion, the participant will be able to:

• Determine a sampling plan for an after fire project.
• Identify hazards to firefighters, trade workers, and occupants.
• Assess the limitations of broad band analysis tools.
• Define when to use/not use gas detection equipment.
• Use IH sampling in sampling plans for these environments.
• Utilize real-time detection systems equipment in sampling plans.
• Manage cross sensitivities to the chemicals present and environmental conditions.
• Use data interpretation to decide if the occupational or residential environment is safe to occupy. 


Attendees should have some experience using direct-read monitoring equipment. 

Value Added

Participants will have a working knowledge of applying sampling techniques after fire environments to ensure the built environment is safe for occupants to re-enter. Attendees will receive a hard copy of "EXPOSED: Carcinogenic Exposures on the Fire Ground and 11 Work Practices to Minimize the Risk". 

Business Case/IH Value Statement

Hazard recognition in post fire environments is largely overlooked. Any person making entry into a post fire environment should be aware of the hazards involved and should wear appropriate PPE including respiratory protection.
