Safety is paramount when working with ammonia refrigerants. Why? If something does go wrong in such a situation, it can have grave consequences.
Ammonia is a health risk because of its corrosiveness to skin, eyes, and lungs. In fact, exposure to 300 ppm creates an imminent danger to life and health. It is important to remember that the safety of technicians and engineers who work with ammonia is as important as in any other working conditions.
