In this class, first responders learn about ammonia characteristics, environmental concerns, associated health effects, EMS options, as well as public safety. Instructors also discuss responder safety and protection, including personal protection equipment (PPE) concerns and isolation or protect-in-place options. There is also a discussion on evacuation versus shelter in-place tactics. The class also covers Material Safety Data Sheets (MSDS) used with alarm scenarios, risk-benefit analysis and troubleshooting real life incidents with illustrations of “first-ins” and incident command responsibilities.
