Emergency overview: This product is corrosive and will cause eye and skin burns. This product may also cause severe irritation and burns of the respiratory tract. Hydroscopic. Appearance: White solid pellets. Flash Point: N/A Warning! Target Organs: Skin, eyes, respiratory tract, mucous membranes. Potential Health Effects Eye: Contact may cause severe burns, chemical conjunctivitis, or corneal damage. Skin: Contact may cause skin burns, deep skin ulcers, rashes, cold/clammy skin with cyanosis or pale color. Ingestion: This product may cause permanent, severe damage of the digestive tract. May cause gastrointestinal burns, perforation of the digestive tract, severe pain, nausea, vomiting, diarrhea, or shock. This product may corrode tissue in the esophagus or digestive tract. May cause systemic effects. Inhalation: Irritation may lead to pulmonary edema or chemical pneumonitis. In addition, inhalation may severely irritate the upper respiratory tract, with symptoms of coughing, burns, difficulty breathing, or potential coma. Causes chemical burns to the respiratory tract. Chronic: Prolonged exposure may cause delayed dermatitis.
Eyes: Immediately flush with running water for at least 15 minutes while holding eyes open. Check for and remove contact lenses. Seek medical attention immediately. Skin: Flush contaminated area thoroughly with water for at least 15 minutes. Remove contaminated clothing and launder before reuse. Seek medical attention immediately.
