DENTSPLY NEACID Chemwatch Material Safety Data Sheet Issue Date: 26-Feb-2009 CHEMWATCH 4613-90 C9317EC Version No:5 CD 2008/4 Page 2 of 6 Section 4 - FIRST AID MEASURES lids. - If pain persists or recurs seek medical attention. - Removal of contact lenses after an eye injury should only be undertaken by skilled personnel. SKIN » If skin contact occurs: - Immediately remove all contaminated clothing, including footwear. - Flush skin and hair with running water (and soap if available). - Seek medical attention in event of irritation. INHALED » - If dust is inhaled, remove from contaminated area. - Encourage patient to blow nose to ensure clear passage of breathing. - If irritation or discomfort persists seek medical attention. NOTES TO PHYSICIAN » Treat symptomatically. 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. Section 5 - FIRE FIGHTING MEASURES EXTINGUISHING MEDIA » - Water spray or fog. - Foam. - Dry chemical powder. - BCF (where regulations permit). FIRE FIGHTING » - Alert Fire Brigade and tell them location and nature of hazard. - Wear full body protective clothing with breathing apparatus. - Prevent, by any means available, spillage from entering drains or water course. - Use fire fighting procedures suitable for surrounding area. When any large container (including road and rail tankers) is involved in a fire, consider evacuation by 800 metres in all directions. FIRE/EXPLOSION HAZARD » - Non combustible. - Not considered to be a significant fire risk. - Acids may react with metals to produce hydrogen, a highly flammable and explosive gas. - Heating may cause expansion or decomposition leading to violent rupture of containers. Decomposition may produce toxic fumes of: ammonia, nitrogen oxides (NOx), sulfur oxides (SOx). FIRE INCOMPATIBILITY » None known. HAZCHEM: 2X Personal Protective Equipment Gas tight chemical resistant suit. Section 6 - ACCIDENTAL RELEASE MEASURES EMERGENCY PROCEDURES MINOR SPILLS » - Drains for storage or use areas should have retention basins for pH adjustments and dilution of spills before discharge or disposal of material. - Check regularly for spills and leaks. - Clean up all spills immediately. - Avoid contact with skin and eyes. - Wear protective clothing, gloves, safety glasses and dust respirator. - Use dry clean up procedures and avoid generating dust. MAJOR SPILLS » - Clear area of personnel and move upwind. - Alert Fire Brigade and tell them location and nature of hazard. - Wear full body protective clothing with breathing apparatus. - Prevent, by any means available, spillage from entering drains or water course. Personal Protective Equipment advice is contained in Section 8 of the MSDS. continued...
DENTSPLY NEACID Chemwatch Material Safety Data Sheet Issue Date: 26-Feb-2009 CHEMWATCH 4613-90 C9317EC Version No:5 CD 2008/4 Page 3 of 6 Section 7 - HANDLING AND STORAGE PROCEDURE FOR HANDLING » - Avoid all personal contact, including inhalation. - Wear protective clothing when risk of exposure occurs. - Use in a well-ventilated area. - Avoid contact with moisture. SUITABLE CONTAINER » - DO NOT use aluminium or galvanised containers. - Glass container is suitable for laboratory quantities. - Lined metal can, lined metal pail/ can. - Plastic pail. - Polyliner drum. - Packing as recommended by manufacturer. STORAGE INCOMPATIBILITY » - Inorganic acids are generally soluble in water with the release of hydrogen ions. The resulting solutions have pH's of less than 7.0. - Inorganic acids neutralise chemical bases (for example: amines and inorganic hydroxides) to form salts - neutralisation can generate dangerously large amounts of heat in small spaces. - The dissolution of inorganic acids in water or the dilution of their concentrated solutions with additional water may generate significant heat. - The addition of water to inorganic acids often generates sufficient heat in the small region of mixing to cause some of the water to boil explosively. The resulting "bumping" can spatter the acid. Avoid contamination / mixing with oxidising agents as ignition may result. - Avoid strong bases. Avoid halogens STORAGE REQUIREMENTS » - Store in original containers. - Keep containers securely sealed. - Store in a cool, dry, well-ventilated area. - Store away from incompatible materials and foodstuff containers. Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION EXPOSURE CONTROLS The following materials had no OELs on our records • sulfamic acid: CAS:5329- 14- 6 PERSONAL PROTECTION RESPIRATOR Particulate EYE » - Safety glasses with side shields. - Chemical goggles. - Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document, describing the wearing of lens or restrictions on use, should be created for each workplace or task. This should include a review of lens absorption and adsorption for the class of chemicals in use and an account of injury experience. Medical and first-aid personnel should be trained in their removal and suitable equipment should be readily available. In the event of chemical exposure, begin eye irrigation immediately and remove contact lens as soon as practicable. Lens should be removed at the first signs of eye redness or irritation - lens should be removed in a clean environment only after workers have washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59]. HANDS/FEET » - Wear chemical protective gloves, eg. PVC. - Wear safety footwear or safety gumboots, eg. Rubber. Suitability and durability of glove type is dependent on usage. Factors such as: - frequency and duration of contact, - chemical resistance of glove material, - glove thickness and - dexterity, OTHER » - Overalls. - PVC Apron. - PVC protective suit may be required if exposure severe. - Eyewash unit. » - Respirators may be necessary when engineering and administrative controls do not adequately prevent exposures. - The decision to use respiratory protection should be based on professional judgment that takes into account toxicity information, exposure measurement data, and frequency and likelihood of the worker's exposure - ensure users are not subject to high thermal loads which may result in heat stress or distress due to personal protective equipment (powered, positive flow, full face apparatus may be an option). - Published occupational exposure limits, where they exist, will assist in determining the adequacy of the selected respiratory .
