Airborne contaminants present the greatest danger to hazardous waste and emergency response workers. Air monitoring is required to identify and quantify airborne hazards, so appropriate protective measures can be implemented. An air-monitoring plan must be included as part of a site-specific Health and Safety Plan (HASP). This module will discuss the requirements of an air monitoring plan, the sensors used to detect hazardous conditions, and what actions should be taken based on monitoring results.

• Describe the purpose of an air monitoring plan • List and describe air monitoring requirements • Describe the different units used to measure gas and vapor concentrations in air • Describe the uses of common gas sensors • Define the different instrument calibration methods • List the action limits for combustible gas, oxygen, and toxic gas concentrations
