Company Identification: Fisher Scientific 1 Reagent Lane Fair Lawn, NJ 07410 For information, call: 201-796-7100 Emergency Number: 201-796-7100 For CHEMTREC assistance, call: 800-424-9300 For International CHEMTREC assistance, call: 703-527-3887 Section 2 - Composition, Information on Ingredients CAS# Chemical Name Percent EINECS/ELINCS 5949-29-1 Citric acid monohydrate >97 unlisted Section 3 - Hazards Identification EMERGENCY OVERVIEW Appearance: white crystalline powder. Danger! Causes severe eye irritation and possible injury. Causes skin and respiratory tract irritation. Target Organs: Respiratory system, eyes, skin. Potential Health Effects Eye: Causes severe eye irritation and possible injury. Skin: Causes skin irritation. Some references state that citric acid has allergenic properties but, no animal or human studies were found to support this claim. It does not seem likely that citric acid is a sensitizer since it is found in the body as an essential component of the citric acid cycle which releases energy for physiological functions. Citric acid is widely distributed in plants and in animal tissues and fluids. Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Excessive intake of citric acid may cause erosion of the teeth. Inhalation: Causes respiratory tract irritation. Chronic: Repeated exposure may cause erosion of teeth. Chronic exposure may cause effects similar to those of acute exposure. Section 4 - First Aid Measures Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid immediately. Skin: In case of contact, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse. Ingestion: If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to Physician: Treat symptomatically and supportively. Section 5 - Fire Fighting Measures General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam. Flash Point: Not applicable. Autoignition Temperature: 1010 deg C ( 1,850.00 deg F) Explosion Limits, Lower:Not available. Upper: Not available. NFPA Rating: (estimated) Health: 3; Flammability: 1; Instability: 0 Section 6 - Accidental Release Measures General Information: Use proper personal protective equipment as indicated in Section 8.
