Unusual Fire Fighting and Explosion Hazards: The dust of citric acid anhydrous and monohydrate can be explosive under some conditions, in air. Where dust concentrations exist sources of ignition should be eliminated. Section V - Reactivity Data Stability Unstable Stable XXX Conditions to Avoid: Compatibility (Materials to Avoid): Alkalies, strong oxidizing agents. Aqueous reaction with strong caustic can create heat (strong exotherm) Hazardous Decomposition or Byproducts: Under combustion conditions carbon dioxide and/or carbon monoxide are evolved.

Hazardous Polymerization May Occur Will Not Occur XXX Conditions to Avoid: ----------------------------------------------------------Section VI - Health Hazard Data ----------------------------------------------------------Route(s) of Entry: Inhalation? Yes Skin? Yes Ingestion? Yes Eyes? Health Hazards (Acute and Chronic): Eyes: Can cause irritation. Severe irritation of the eye indicated in rabbit eye testing. Skin: May cause irritation: Inhalation of dust may cause irritation of nasal and respiratory passages. Ingestion: In excess can cause gastrointestinal irritation. Oral LD (50) (mouse)-504 mg/kg (3) (rat) 11700mg/kg. Carcinogenicity: None NTP? IARC Monographs? OSHA Regulated? Signs of Symptoms of Exposure: Burning eyes, skin, mouth, or mucous membranes. Medical Conditions Generally Aggravated by Exposure: Not determined. Emergency and First Aid Procedures: Eye Contact: Flush with water for 15 minutes while holding eyelids open. Get medical attention if irritation persists. Skin Contact: Flush with water and remove contaminated clothing and shoes, follow by washing with soap and water. Do not reuse clothing or shoes until cleaned. If irritation persists, get medical attention. Inhalation: Move to fresh air, consult with a physician if irritation persists. Ingestion: Drink plenty of water and get medical attention. ----------------------------------------------------------Section VII - Precautions for Safe Handling and Use ----------------------------------------------------------Steps to Be Taken in Case Material is Released or Spilled: Vacuum or sweep up and shovel into containers. Workers should wear the protective gloves, goggles and bodycovering clothing. Residual material may be wetted, neutralized with soda ash or Sodium Bicarbonate, diluted with water, and wet vacuumed into containers for disposal. Keep out of natural waterways. Waste Disposal Method: Subject to approval by federal, state, and local authorities unrecoverable product, dissolved in water, neutralized, and diluted by further addition of water may be washed to the sewer. With regard to citrate's effect on sewage treatment, citrate has been shown to be highly degradable, in laboratory-activated sludge systems. (0(2) consumptions, 98% of theoretical) and in trickling filters. Precautions to Be Taken in Handling and Storing : Store in closed containers to prevent dusting. No open flames, sparks, or other sources of ignition where dusty atmospheric conditions may exist. Other Precautions: None specified. ----------------------------------------------------------Section VIll - Control Measures ----------------------------------------------------------Respiratory Protection (Specify Type): If needed use a NIOSH/MSHA jointly a roved dust respirator. Ventilation Local Exhaust: As needed to maintain exposure level below PEL/TLV for nuisance dust. Mechanical (General): See local exhaust Special: Other:
