Although there may be a temptation to simply treat A2L refrigerants as equivalent to ammonia with respect to flammability hazard, ammonia really is an entity unto itself. Like an A2L, it exhibits a low-flame velocity in flammability tests, but ammonia has the unique safety advantage of a strong and unmistakable odor that is typically present long before the onset of a flammability hazard. All of the current A2L refrigerants, on the other hand, are odorless.
