Hazards and Protection.
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Reacts as acid to neutralize bases.
When heated to decomposition, emits toxic fumes of hydrogen fluoride.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
Some may burn but none ignite readily. May polymerize explosively when heated or involved in a fire. Containers may explode when heated. Some may be transported hot.
Fire may produce irritating, corrosive and/or toxic gases.
Hyperactive reflexes, painful muscle spasms, weakness and tetanic contractures may be noted due to fluoride induced hypocalcemia. Prenatal fluoride supplementation (2.2 mg NaF or 1 mg fluoride daily) during the last two trimesters of pregnancy has been reported to be safe.
Epigastric pain, nausea, dysphagia, salivation, hematemesis, and diarrhea may be noted. These effects may be delayed for several hours following exposure. Gi symptoms are noted when 3 to 5 mg/kg of fluoride are ingested.
Respirations are first stimulated then depressed. Death is usually from respiratory paralysis. Following inhalation, coughing and choking may be noted.
Urticaria and pruritus have been reported following exposure to fluoride.
Zirconium and its compounds are eye irritants.
Seek medical assistance.
Move to fresh air.
Wash with soap and water.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
