OSHA PEL ACGIH TLV NIOSH REL NIOSH Ingredient TWA STEL TWA STEL TWA STEL IDLH Sodium none estab. Ferrocyanide Section 4 - First Aid Measures Inhalation: Supply fresh air. If required, provide artificial respiration. Eye Contact: Rinse opened eye for several minutes under running water. Then consult a doctor if irritation persists. Skin Contact: Immediately wash with water and soap and rinse thoroughly. Seek medical advice if irritation persists. Ingestion: If material is swallowed, induce vomiting if patient is conscious. Never give anything by mouth to an unconscious person. Seek medical advice. After first aid, get appropriate in-plant, paramedic, or community medical support. Note to Physicians: Treat symptomatically and supportively. Section 5 - Fire-Fighting Measures Flash Point: not applicable NFPA Flash Point Method: Burning Rate: 0 Auto-ignition Temperature: not determined 2 0 LEL: not determined — UEL: not determined Flammability Classification: Product is not flammable. Extinguishing Media: Product is not flammable. Use firefighting measures that suit the surrounding fire. Unusual Fire or Explosion Hazards: none Hazardous Combustion Products: Fire-Fighting Instructions: Do not release runoff from fire control methods to sewers or waterways. Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear a self-contained breathing apparatus (SCBA) with a full face-piece operated in pressure-demand or positive-pressure mode. Section 6 - Accidental Release Measures Spill /Leak Procedures: Wear protective equipment. Keep unprotected persons away. Ensure adequate ventilation. Avoid raising dust. Eliminate flammables. Eliminate all ignition sources. Dispose contaminated material as waste according to official regulations. Large Spills Containment: For large spills, dike far ahead of liquid spill for later disposal. Do not release into sewers or waterways. Cleanup: Water, if necessary with cleansing agents. Regulatory Requirements: Follow applicable OSHA regulations (29 CFR 1910.120). Section 7 - Handling and Storage Handling Precautions: Keep container tightly sealed. Storage Requirements: Store in a cool, dry, well-ventilated area away from incompatible substances. Section 8 - Exposure Controls / Personal Protection Engineering Controls: Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs (Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at its source. Administrative Controls: Page 2 of 5 Respiratory Protection: Seek professional advice prior to respirator selection and use. Follow OSHA respirator regulations (29 CFR 1910.134) and, if necessary, wear a MSHA/NIOSH-approved respirator. Select respirator based on its suitability to provide adequate worker protection for given working conditions, level of airborne contamination, and presence of sufficient oxygen. For emergency or non-routine operations (cleaning spills, reactor vessels, or storage tanks), wear an SCBA. Warning! Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. If respirators are used, OSHA requires a written respiratory protection program that includes at least: medical certification, training, fit-testing, periodic environmental monitoring, maintenance, inspection, cleaning, and convenient, sanitary storage areas. Protective Clothing/Equipment: Wear chemically protective gloves, boots, aprons, and gauntlets to prevent prolonged or repeated skin contact. Wear protective eyeglasses or chemical safety goggles, per OSHA eye- and face-protection regulations (29 CFR 1910.133). Contact lenses are not eye protective devices. Appropriate eye protection must be worn instead of, or in conjunction with contact lenses. Safety Stations: Make emergency eyewash stations, safety/quick-drench showers, and washing facilities available in work area. Contaminated Equipment: Separate contaminated work clothes from street clothes. Launder before reuse. Remove this material from your shoes and clean personal protective equipment. Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this material, especially before eating, drinking, smoking, using the toilet, or applying cosmetics.

ACIDS: Evolution of highly toxic and flammable hydrogen cyanide gas. OXIDIZERS (STRONG): Fire and explosion hazard. Hazardous Decomposition Products: Thermal oxidative decomposition of Sodium Ferrocyanide can produce oxides of nitrogen, carbon monoxide, carbon dioxide and hydrogen cyanide. Section 11- Toxicological Information SODIUM FERROCYANIDE: ADDITIONAL DATA: Because of the strong chemical bond between the cyanide group and the iron, ferrocyanides do not release cyanide under normal conditions. However, certain industrial processes may release hydrogen cyanide which is a chemical asphyxiant. Toxicity Oral (rat) LD50: 5100 mg/kg HEALTH EFFECTS: INHALATION: ACUTE EXPOSURE: SODIUM FERROCYANIDE: May cause irritation to the respiratory tract. Ferrocyanides have a low order of toxicity. However, certain industrial processes may release hydrogen cyanide which is a chemical asphyxiant. CHRONIC EXPOSURE: SODIUM FERROCYANIDE: No data available. SKIN CONTACT: ACUTE EXPOSURE: Page 3 of 5 SODIUM FERROCYANIDE: May cause irritation. CHRONIC EXPOSURE: SODIUM FERROCYANIDE: No specific data available.
