Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. Continue flushing until advised to stop by the Poisons Information Centre or a doctor, or for at least 15 minutes. Transport to hospital or doctor without delay. Removal of contact lenses after an eye injury should only be undertaken by skilled personnel. If there is evidence of severe skin irritation or skin burns: Avoid further contact. Immediately remove contaminated clothing, including footwear. Flush skin under running water for 15 minutes. Avoiding contamination of the hands, massage calcium gluconate gel into affected areas, pay particular attention to creases in skin. Skin Contact Contact the Poisons Information Centre. Continue gel application for at least 15 minutes after burning sensation ceases. If pain recurs, repeat application of calcium gluconate gel or apply every 20 minutes. If no gel is available, continue washing for at least 15 minutes, using soap if available. If patient is conscious, give six calcium gluconate or calcium carbonate tablets in water by mouth. Transport to hospital, or doctor, urgently. If dust is inhaled, remove from contaminated area. Encourage patient to blow nose to ensure clear breathing passages. Ask patient to rinse mouth with water but to not drink water. Seek immediate medical attention. For massive exposures: If dusts, vapours, aerosols, fumes or combustion products are inhaled, remove from contaminated area. Lay patient down. Inhalation Keep warm and rested. Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures. Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. If victim is conscious, give six calcium gluconate or calcium carbonate tablets in water by mouth. Transport to hospital, or doctor, urgently. For advice, contact a Poisons Information Centre or a doctor at once. Urgent hospital treatment is likely to be needed. If swallowed do NOT induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and Ingestion prevent aspiration. Observe the patient carefully. Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious. Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink. Transport to hospital or doctor without delay. Indication of any immediate medical attention and special treatment needed For acute or short term repeated exposures to fluorides: Fluoride absorption from gastro-intestinal tract may be retarded by calcium salts, milk or antacids. Fluoride particulates or fume may be absorbed through the respiratory tract with 20-30% deposited at alveolar level. Peak serum levels are reached 30 mins. post-exposure; 50% appears in the urine within 24 hours. For acute poisoning (endotracheal intubation if inadequate tidal volume), monitor breathing and evaluate/monitor blood pressure and pulse frequently since shock may supervene with little warning. Monitor ECG immediately; watch for arrhythmias and evidence of Q-T prolongation or T-wave changes. Maintain monitor. Treat shock vigorously with isotonic saline (in 5% glucose) to restore blood volume and enhance renal excretion. Where evidence of hypocalcaemic or normocalcaemic tetany exists, calcium gluconate (10 ml of a 10% solution) is injected to avoid tachycardia. BIOLOGICAL EXPOSURE INDEX - BEI These represent the determinants observed in specimens collected from a healthy worker exposed at the Exposure Standard (ES or TLV): Determinant Index Sampling Time Comments Fluorides in urine 3 mg/gm creatinine Prior to shift B, NS 10mg/gm creatinine End of shift B, NS B: Background levels occur in specimens collected from subjects NOT exposed NS: Non-specific determinant; also observed after exposure to other exposures. For acute or short term repeated exposures to strong acids: Airway problems may arise from laryngeal edema and inhalation exposure. Treat with 100% oxygen initially. Respiratory distress may require cricothyroidotomy if endotracheal intubation is contraindicated by excessive swelling Intravenous lines should be established immediately in all cases where there is evidence of circulatory compromise. Strong acids produce a coagulation necrosis characterised by formation of a coagulum (eschar) as a result of the dessicating action of the acid on proteins in specific tissues. INGESTION: Immediate dilution (milk or water) within 30 minutes post ingestion is recommended. DO NOT attempt to neutralise the acid since exothermic reaction may extend the corrosive injury. Be careful to avoid further vomit since re-exposure of the mucosa to the acid is harmful. Limit fluids to one or two glasses in an adult. Charcoal has no place in acid management. Some authors suggest the use of lavage within 1 hour of ingestion. SKIN: Skin lesions require copious saline irrigation. Treat chemical burns as thermal burns with non-adherent gauze and wrapping. Deep second-degree burns may benefit from topical silver sulfadiazine. EYE: Eye injuries require retraction of the eyelids to ensure thorough irrigation of the conjuctival cul-de-sacs. Irrigation should last at least 20-30 minutes. DO NOT use neutralising agents or any other additives. Several litres of saline are required. Cycloplegic drops, (1% cyclopentolate

Box 13501 Research Triangle Park, North Carolina 27709 October 2001 Toxicological Summary for Sodium Hexafluorosilicate [16893-85-9] and Fluorosilicic Acid [16961-83-4] 10/01 Executive Summary Nomination Sodium hexafluorosilicate and fluorosilicic acid were nominated for toxicological testing based on their widespread use in water fluoridation and concerns that if they are not completely dissociated to silica and fluoride in water that persons drinking fluoridated water may be exposed to compounds that have not been thoroughly tested for toxicity. Nontoxicological Data Analysis and Physical-Chemical Properties Analytical methods for sodium hexafluorosilicate include the lead chlorofluoride method (for total fluorine) and an ion-specific electrode procedure. The percentage of fluorosilicic acid content for water supply service application can be determined by the specific-gravity method and the hydrogen titration method. The American Water Works Association (AWWA) has specified that fluorosilicic acid contain 20 to 30% active ingredient, a maximum of 1% hydrofluoric acid, a maximum of 200 mg/kg heavy metals (as lead), and no amounts of soluble mineral or organic substance capable of causing health effects.

    ECONOMIC COMMISSION FOR EUROPE INLAND TRANSPORT COMMITTEE INF.6 Working Party on the Transport of Dangerous Goods Joint Meeting of the RID Safety Committee and the Working Party on the Transport of Dangerous Goods (Geneva, 1-10 September 2003) Harmonization with the UN Recommendations on the Transport of Dangerous Goods Bulk containers Transmitted by the Government of the United Kingdom 1. Introduction New provisions for bulk containers from the UN Model Regulations are being proposed for inclusion in RID/ADR based on text prepared by the UN Secretariat and as discussed at the ad hoc Working Group on the Harmonization of RID/ADR/ADN with the UN Recommendations on the Transport of Dangerous Goods that met from 26-28 May 2003. The results of the discussions on this subject are recorded in paragraphs 39 to 46 of the report of the ad hoc Working Group TRANS/WP.15/AC.1/2003/56 and the proposed text for inclusion in RID/ADR in the relevant parts of Addendum 1 to 7 of 2003/56, in particular a new chapter 6.11 and a modified chapter 7.3. 2. Proposal and Justification A new chapter 6.11, reflecting UN chapter 6.8, is contained in 2003/56 Add 6 dealing with the requirements for the design, construction, inspection and testing of bulk containers and new UN chapter 4.3 dealing with the use of bulk containers has been integrated into a modified chapter 7.3 contained in 2003/56 Add 7. Now that there are comprehensive provisions for bulk containers developed at UN level, the UK believes as reflected in paragraph 43 of 2003/56, that these should now apply to carriage in bulk in RID/ADR rather than have two separate systems based on the provisions for bulk containers in UN and the existing provisions in RID/ADR.

Calgary, AB, T2E6P6 [email protected]: ABSTRACT The removal of silica scale deposits from process equipment Table 2 : Heat transfer coefficients for various scales represents a substantial challenge in chemical cleaning. Q/A for various Scale types Silicates form in a variety of systems as the result of their presence in natural water and in water treatment chemistry. T1-T2 (°C) The exact nature of the silicate in deposits depends on the Scale K2 20 40 100 type of cations present as well as temperature and flow rates when the silicate is deposited. Removing silicate deposits None 0 270.00 540.00 1350 has depended on using fluorine based acids, such as HF, Glass 0.96 112.21 224.42 561.04 Ammonium bifluoride, and Fluoroboric acid. HF and related Silica 0.06 11.49 22.98 57.45 acids are very hazardous. In addition Fluoride ions form a number of insoluble salts that can limit the effectiveness of Clay 0.15 27.00 54.00 135.00 the acid in dissolving silicate scales.

Noncombustible. Corrodes aluminum. Used as a disinfectant, in etching glass, metal casting, and electroplating. Hazards Reactivity Alerts Water-Reactive Air-Reactive Air & Water Reactions Water soluble. Fire Hazard Special Hazards of Combustion Products: Toxic and irritating hydrogen fluoride, silicon tetrafluoride, and oxides of nitrogen may form in fires. (USCG, 1999) Health Hazard Inhalation of dust can cause pulmonary irritation and can be fatal in some cases. Ingestion may be fatal. Contact with dust causes irritation of eyes and irritation or ulceration of skin. (USCG, 1999) Reactivity Profile Salts, basic, such as AMMONIUM FLUOROSILICATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Ammonium fluorosilicate reacts with water to form hydrofluoric acid, a source of fluoride ions. Unlike other halide ions, the https://cameochemicals.noaa.gov/report?key=CH5407 1/4 10/16/2017 Report | CAMEO Chemicals | NOAA fluoride ion is quite reactive, acting as a weak base and participating in some unique reactions.
