6、e, solid that consists of crystals or flakes with a pungent odor. This product is corrosive and causes severe irritation and burning of the eyes, skin and mucous membranes. Harmful or fatal if swallowed, inhaled or if absorbed through the skin. Chronic, low level exposure can lead to bone or dental
7、fluorosis. Fire may produce irritating, corrosive and/or toxic vapors (e.g. ammonia, hydrogen fluoride, and nitrogen oxides). Firefighters should use full protective equipment and clothing. Hazard Statements CORROSIVE. CAUSES SKIN, EYE AND RESPIRATORY TRACT BURNS. HARMFUL OR FATAL IF SWALLOWED, INHA
8、LED OR IF ABSORBED THROUGH THE SKIN. Do not taste or swallow. Avoid breathing dusts or particulates. Avoid contact with eyes, skin or clothing. Avoid breathing dusts. Wash thoroughly after handling. Keep container closed. Do not store in glass or silicate-based containers. Use with adequate ventilat
9、ion. Potential Health Effects: Eyes Exposure to particulates or solution of this product may cause redness, pain and blurred vision. Prolonged contact may cause corneal injury or, in severe cases, blindness. Effects may be delayed. Potential Health Effects: Skin This product can cause irritation of
10、the skin with pain, itching and redness. Ammonium Bifluoride can cause severe necrosis to tissue, with symptoms such as redness, itching, burns and scarring. Burns may not be immediately visible or painful. Ammonium Bifluoride can cause a unique, large, pustular skin rash, which is apparently not an
11、 irritant or allergic dermatitis. As a fluoride compound, Ammonium Bifluoride has the potential to decompose upon contact with moisture to form hydrofluoric acid, which can penetrate the skin, causing destruction of the deep tissue layers, including bone tissue. This damage to the bodys tissues may
12、continue for days, as the fluoride ion reacts with the calcium in the skin and bone. Severe skin-contact exposures (especially when the skin contamination exceeds 160 cm2) can lead to hypocalcemia, a life-threatening lowering of serum calcium in the body. Ammonium Bifluoride may be systematically ab
13、sorbed in lethal amounts through intact skin. Effects may be delayed and not felt for hours. Potential Health Effects: Ingestion Harmful if swallowed. Data indicate that ingestion of between 1 teaspoon and 1 ounce may be fatal. This product may cause corrosive damage to gastrointestinal tract, sympt
14、oms of such over-exposure include, salivation, nausea, vomiting, diarrhea, hypocalcemia, burning pain, convulsions, shock, muscle spasms, coma, cardiac arrhythmias, cardio and pulmonary arrest, and possibly, death. At high concentrations, there is a risk of hypocalcemia. Potential Health Effects: In
15、halation This product is irritating to the nose, throat and respiratory tract. Symptoms can include sore throat, coughing and shortness of breath. In severe cases, ulceration and perforation of the nasal septum and upper respiratory tract can occur,. Inhalation of high concentrations can lead to che
16、mical pneumonia, pulmonary edema, and hypocalcemia. Effects may be delayed.

If th
18、ere is a difficulty in keeping eyes open during irrigation, administer anesthetic drops. If calcium gluconate 1% solution is available, it should be administered. Seek immediate medical attention, preferably an ophthalmologist. First Aid: Skin Remove all contaminated clothing. For skin contact, wash
19、 thoroughly with soap and water for at least 20 minutes. Apply calcium gluconate gel (2.5%) and massage into affected area (hands must be gloved); continue massage while repeatedly applying gel until 15 minutes after pain has ceased. Seek immediate medical attention. First Aid: Ingestion DO NOT INDU
20、CE VOMITING. Never give anything by mouth to a victim who is unconscious or having convulsions. Have victim rinse mouth thoroughly with water, if conscious. Attempt immediate administration of a fluoride binding substance with oral exposures. Options include milk (4 to 8 ounces), chewable calcium ca
21、rbonate tablets or Milk of Magnesia. Avoid large amounts of liquid, since this may induce vomiting. Contact a physician or poison control center immediately. First Aid: Inhalation Remove source of contamination or move victim to fresh air. Apply artificial respiration if victim is not breathing. Do
22、not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Get immediate medical attention. First Aid: No
23、tes to Physician Provide general supportive measures and treat symptomatically. For eye contamination rinse eye(s) with a calcium gluconate 1% solution in physiological serum (10 mL of calcium gluconate 10% in 90 mL of physiological serum). In case of difficulty of opening lids, administer an analge
24、sic eye wash (oxybuprocaine). For skin contact, application of calcium gluconate gel (2.5%) should occur 4 to 6 times per day. If victim suffers second or third degree burns, subcutaneous injection of 10% calcium gluconate at a distance of 7 mm around the affected area. If fingers or toes have been
25、contaminated, dip in a bath of 5% calcium gluconate for 15 to 20 minutes. For severe burns of the digits, slow intraarterial infusion (over a 4 hour period) of 10 mL of a 10% calcium gluconate solution diluted in 40 mL of physiological serum. Phlyctenae and necrotic tissue should be debrided (warnin
26、g: liquid in phlyctenae is corrosive). For ingestion exposure, provide oxygen therapy via intratracheal intubation, if breathing is difficult or victim is not breathing. If throat is constricted due to burns, perform tracheotomy. Careful gastric lavage should be performed after administration of 10
27、vials of calcium gluconate. Repeat as often as necessary. In case of intense pain, inject an I.M. morphomimectic analgesic drug (e.g. piritramide) prior to transport. Prevention and treatment for shock, pulmonary edema and esophageal stenosis, as well as hypocalcemia should occur. Examination by dig
28、estive tract endoscopy should be performed in all cases. In case of hypocalcemia, administer I.V. perfusion of 20 mL of a 10% calcium gluconate solution diluted in 1 liter of physiological serum. Surveillance of hyperfluoremia should occur, with possible treatment with hemodialysis should occur, as
29、well as surveillance of cardiac ECG, and respiratory and renal function. * * * Section 5 - Fire Fighting Measures * * * Flash Point: Not flammable Method Used: Not applicable Upper Flammable Limit (UEL): Not applicable Lower Flammable Limit (LEL): Not applicable Auto Ignition: Not available Flammabi
