Leakage should be prevented, especiallyVacuum Heat Treatment of Aerospace Fasteners Prevent the human body from contacting with liquid ammonia, otherwise it will cause skin burns. 2. Frequently check and maintain the airtightness of the gas system of the device. The leakage of ammonia gas has an irritating odor, while the decomposition gas is colorless and odorless, but it is flammable and explosive gas.
