"Your Safer Source for Science Supplies" MSDS #: 355.00 Revision Date: March 14, 2001 Material Safety Data Sheet (MSDS) Section 1 — Chemical Product and Company Identification Formic Acid Flinn Scientific, Inc. P.O. Box 219 Batavia, IL 60510 (800) 452-1261 CHEMTREC Emergency Phone Number: (800) 424-9300 Section 2 — Composition, Information on Ingredients Formic Acid Synonym: aminic acid CAS#: 64-18-6 Section 3 — Hazards Identification Clear, colorless, fuming liquid; penetrating odor. FLINN AT-A-GLANCE Corrosive to body tissue. Highly caustic to skin. Slightly toxic by ingestion and inhalation. Avoid Health-2 contact with skin, eyes or mucous membranes. Flammability-1 Combustible liquid. Reactivity-1 Exposure-3 Storage-3 0 is low hazard, 3 is high hazard Section 4 — First Aid Measures Call a physician, seek medical attention for further treatment, observation and support after first aid. Inhalation: Remove to fresh air at once. If breathing has stopped give artificial respiration immediately. Eye: Immediately flush with fresh water for 15 minutes. External: Wash continuously with fresh water for 15 minutes. Internal: Give no more than 1-2 cups of water for dilution. Do not induce vomiting. Call a physician or poison control at once. Section 5 — Fire Fighting Measures Class IIIA Combustible liquid. NFPA CODE Flash Point: 156 F Upper: 57% Lower: 18% Autoignition Temperature: 1004 F H-3 When heated to decomposition, emits acrid smoke and fumes. F-2 Fire Fighting Instructions: Use triclass, dry chemical fire extinguisher. Firefighters should wear PPE R-0 and SCBA with full facepiece operated in positive pressure mode. Section 6 — Accidental Release Measures Restrict unprotected personnel from area. Remove all ignition sources and ventilate area. Contain spill with sand and absorbent material, neutralize with sodium bicarbonate or calcium hydroxide and deposit in sealed bag or container. See Sections 8 and 13 for further information. Section 7 — Handling and Storage Flinn Suggested Chemical Storage Pattern: Organic #1. Store with acids, anhydrides and peracids. Store in a dedicated acid cabinet and away from any source of water; if an acid cabinet is not available, store in a Flinn Sar-Cube. Recent information suggests it ages poorly and may be an explosion risk. Avoid extended storage. Use and dispense in a hood. Section 8 — Exposure Controls , Personal Protection Avoid contact with eyes, skin and clothing. Wear chemical splash goggles, chemical-resistant gloves and chemical-resistant apron. Use ventilation to keep airborne concentrations below exposure limits. Always wear a NIOSH-approved respirator with proper cartridges or a positive pressure, air-supplied respirator when handling this material in emergency situations (spill or fire).
