NH3 Anhydrous Ammonia

Potential health effects

Causes skin and eye burns; eye damage may be permanent, including blindness. Causes nose, throat, and lung irritation. Contact with liquid may cause frostbite. Gross overexposure may be fatal. Skin contact may cause skin irritation with discomfort or rash. Skin contact with liquified compressed gas will cause frostbite and dermatitis. Eye contact may cause eye irritation with discomfort, tearing, or blurring of vision. Inhalation may cause irritation of the upper respiratory passages, or nonspecific discomfort such as headache. Ingestion may cause corrosive injury to the mouth, esophagus, and stomach, leading to pain, vomiting, and circulatory collapse. Perforation of the gastrointestinal tract can occur. Higher exposures may lead to skin burns or ulceration; eye corrosion with corneal or conjunctival ulceration, or blindness; temporary lung irritation effects with possible modest initial symptoms such as cough, discomfort, difficulty in breathing or shortness of breath, followed in hours by severe shortness of breath requiring prompt medical attention; nonspecific discomfort such as nausea, headache, or weakness. Fatality may occur from gross overexposure. The compound has been infrequently associated with skin sensitization in humans. The concentration of ammonia that is Immediately Dangerous to Life and Health (IDLH) is 300 ppm in air. Individuals with preexisting diseases of the lungs, skin, or eyes may have increased susceptibility to the toxicity of excessive exposures. Carcinogenicity Information None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen. ----------------------------------------------------------------------
