Carbon Monoxide and Associated Dangers
I. Course Prefix/Number: AHR 107
Course Name: Carbon Monoxide and Associated Dangers
Credits: 2 (2 lecture; 2 lab)
III. Course (Catalog) Description
Course covers how to evaluate buildings that may have a high level of carbon monoxide due to being tightly sealed to reduce air infiltration. HVACR technicians and first responders will gain knowledge to analyze building structures and eliminate hazards associated with carbon monoxide poisoning. Course is designed to prepare students to take the ESCO Institute Carbon Monoxide Certification test and gain certification. This is a classroom course only.
