Air monitoring and sample identification are critical skills essential to the successful outcome of hazardous materials incidents. It is essential to determine airborne contaminant levels in order to remain compliant with action levels, especially those associated with personal protective equipment (PPE) level selection. This course is designed to make hazmat responders aware of the latest equipment available as well as proficient in its use. This week-long course has many hands-on activities involving actual gas samples. Students will become intimately familiar with common air monitoring equipment such as 4-gas meters, photoionization detectors (PID), colorimetric tubes, and Geiger counters.
