How to protect from and avoid ammonia exposure.
Structural fire fighting clothing can provide limited protection from anhydrous ammonia vapors provided it is during an outdoor release and the responders are using proper technique. Only firefighters trained in anhydrous ammonia response should be allowed to approach an ammonia release.
The SCBA will provide eye and respiratory protection and the fire fighter's turnout gear will protect from skin exposure. Skin exposed through the openings around the pant legs and sleeves are usually enough to cause only slight skin irritation. Always keep the ear flaps down and the coat collar up as well as having manned water lines nearby and ready.
Remember, structural fire fighting gear will NOT protect you from liquid ammonia.
Under emergency conditions where contact with liquid ammonia or highly concentrated vapors is probable, chemically resistant, gastight totally encapsulating suits with positive pressure SCBA is required.
