Self-contained breathing apparatus may be required when chemical is heated to decomposition or in a spill area. Eye and Face Protection:Splash-proof goggles should be worn when there is danger of splash from solution containing chemical. Protection against splash or mist from solution containing chemical with 8-inch minimum face shield is recommended. Eye protection should be worn in presence of dry chemical, or solution containing chemical, at all times. Hand, Arm and Body Protection:Impervious gloves should be worn. Protective, impervious clothing should be worn in presence to prevent contact with skin (coveralls, boots, etc.) Other Protective Clothing and Equipment:Protect open wounds. Heating to decomposition requires full protective clothing and self-contained breathing apparatus. Engineering Controls:Adequate ventilation to maintain fluoride concentrations below applicable standards. Section III HEALTH INFORMATIONOSHA Permissible Exposure Limit (PEL):2.5mg/m3(as F) ACGIH Threshold Limit Value (TLV):2.5mg/m3(as F) Listing in the following: New Jersey Right to Know laws-Yes Toxic Substances Control Act Inventory of Toxic Substances (TSCA)-Yes Workplace Hazardous Materials Information System (WHMIS)-Yes OSHA Health Hazard Classification:Toxic. Primary Route(s) of Entry:Eye and skin contact, inhalation Symptoms of Exposure:Acute:Fluoride dust may cause irritation to eyes and respiratory tract. Swallowing fluoride dust may cause nausea, vomiting, abdominal pain or burning, diarrhea, shortness of breath, difficulty in speaking, thirst, weakness of pulse, disturbed color vision, muscular weakness, convulsions, loss of consciousness and death. Kidney injury and bleeding from injury may occur.Chronic:Repeated exposure above the PEL or TLV to fluoride dust may cause excessive calcification of ligaments of the ribs, pelvis and spinal column. Sclerosis of changes of bones and ligaments can be seen by x-ray. Enzyme system effects and pulmonary fibrosis are reported. Stiffness and limitation of motions may result. Common findings are eye, skin, and mucous membrane irritation, loss of weight, anorexia, anemia, wasting, cachexia, and dental defects. Repeated or prolonged exposure to the skin may cause skin rash. Aggravated Medical Condition:Pre-existing respiratory diseases including asthma and emphysema.toxic Data:125 mg/kg (Oral - Rat) Section IV EMERGENCY AND FIRST AID PROCEDURESInhalation:If a person breathes in chemical dust, remove exposed person promptly to fresh air. If breathing has stopped, perform artificial respiration. Oxygen should be provided for a person having difficulty breathing (but only administered by an authorized individual) until the person is able to breath easily by themselves. Keep the affected person warm and at rest. Get medical attention as soon as possible.Eye Contact:Flush eyes with large amounts of water, lifting the upper and lower lids at periodic intervals to insure contact of water with all accessible tissue of the eyes and lids. Medical attention should be given as soon as possible, preferably an eye specialist.Skin Contact:Promptly wash the contaminated skin using soap or mild detergent and water. If chemical, or solution containing chemical, soaks through clothing, remove the clothing promptly and wash the skin using soap or mild detergent and water. Medical attention should be given as soon as possible for all burns, regardless of how minor thy seem.Ingestion:If conscious, give the exposed person large quantities of water immediately. Do NOT induce vomiting. Several glasses of milk may be given for its soothing effect. A physician should be contacted immediately.Note to Physician:Exposed person should be observed for 48 - 72 hours for delayed onset of pulmonary edema.

Section VII REACTIVITY Stability:Stable.Hazardous Polymerization:Will not occur.Conditions and Materials to Avoid:Contact with strong acids and alkalis,such contact will cause formation of hydrogen fluoride gas.Hazardous Decomposition Products:Temperatures above 500C, such as fires, will cause decomposition and formation of hydrofluoric acid and fluorine. Section VIII FIRE AND EXPLOSION HAZARDS Flash Point and Method Used:N/AFlammable Limits - % Volume in Air:LowerN/AUpperN/AExtinguishing Media:This chemical is not flammable, but for fires in area where this chemical is stored, use foam, dry chemicals or CO2.Special Fire Fighting Procedures and Precautions:When this product is heated to decomposition (500C), it will generate highly toxic gases such as hydrogen fluoride.Auto Ignition Temperature:N/AUnusual Fire and Explosion Hazards:Extreme temperatures, such as fires, will cause decomposition and formation fluorine. Firefighters should avoid all bodily contact, wear full protective clothing and self-contained breathing apparatus. Section IX STORAGE AND SPECIAL PRECAUTIONS Handling and Storing Precautions: Store in a cool, dry place and away from acids. Use only with adequate ventilation, dust mask or self-contained breathing apparatus. Protective clothing should always be worn. Avoid contact with eyes, skin, and clothing. Keep bag or container closed when not in use. Avoid breathing dust or mist.Ventilation:Provide adequate general and/or local exhaust to maintain vapors below acceptable air level maximums.Other Precautions:Do not get on skin, clothing, or in eyes. Wash off with water. Do not take internally. Do not breathe dust. Keep separated from strong acids and alkalis.Section X TRANSPORTATION REQUIREMENTSDOT Proper Shipping Name:Sodium FluorosilicatePacking Group:IIIDOT Hazard Class:6.1 (Poison)Subsidiary Hazard Class:N/AIdentification Number:UN 2674Reportable Quantity:N/APlacarding Requirement:Toxic.EPA Hazardous Substance:NoIMDG Placarding Requirement:Toxic.RCRA Status of Unused Material if Discarded:Not ListedHazardous Waste Number:Not ListedWaste Disposal Method:Disposer must comply with federal, state and local disposal or discharge laws.Additional Comments:For International transportation, Sodium Fluorosilicate is regulated by the International Maritime Organization (IMO) and the International Air Transport Association (IATA)for vessel and air movement as a Class 6.1 toxic and NOT marked as a marine pollutant, (MDG pg. 6250).
