Extinguishing Media: Dry chemical, Class D extinguisher. DO NOT USE WATER.
Special Fire Fighting Procedures: Firefighters should wear a NIOSH/MSHA approved self-contained breathing apparatus and full protective clothing.
Unusual Fire and Explosion Hazards: Product will burn under fire conditions. May react with water liberating flammable, explosive hydrogen gas. Like all organic and most dry chemicals, as a powder or dust, this product (when mixed with air in critical proportions and in the presence of an ignition source) may present an explosion hazard.
V. HEALTH HAZARD INFORMATION
Acute Effects:
Inhalation: Low acute inhalation toxicity. May cause upper respiratory tract irritation.
Ingestion: Evidence suggest low toxicity potential due to poor absorption by the oral route.
Skin: Skin absorption not likely. Essentially non-irritating.
Eye: Non-irritating. May cause foreign body irritation only.
Chronic Effects: No data found.
Other: Has anticoagulant effect when given intravenously.
Medical Conditions Possibly Aggravated by Overexposure: Inhalation of product may aggravate existing chronic respiratory problems such as asthma, emphysema or bronchitis.
Carcinogenicity: NTP: No IARC: No OSHA: No ACGIH: No
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: If respiratory irritation or distress occurs remove victim to fresh air. Seek medical attention if respiratory irritation or distress continues.
INGESTION: If victim is conscious and alert, give 1-2 glasses of water to drink. Do not give anything by mouth to an unconscious person. Seek medical attention. Do not leave victim unattended.
SKIN: In case of contact, wash with plenty of soap and water. Seek medical attention if irritation develops or persists.
EYES: In case of contact, immediately flush eye with plenty of water for at least 15 minutes using an eyewash fountain. Lift upper and lower lids and rinse well under them. Get medical attention if irritation develops or persists.
NOTE TO PHYSICIAN: All treatments should be based on observed signs and symptoms of distress in the patient. Consideration should be given to the possibility that overexposure to materials other than this product may have occurred. Treat symptomatically. No specific antidote available.

Protective Gloves: Impervious gloves
Eye Protection: Safety glasses with side shields, chemical workers dust-proof goggles.
Protective Clothing: Work clothing and gloves.
IX. SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in a cool, dry place in tightly closed containers. Air and moisture sensitive. Store away for oxidizers and other materials listed under incompatibility. STORE UNDER ARGON OR OTHER INERT ENVIRONMENT. Avoid breathing dusts. Avoid direct or prolonged contact with skin and eyes. Do not rub eyes with soiled hands.
Other Precautions: Avoid creating dusts as this product, like most materials in powder form, is capable of creating a dust explosion.
Work Practices: Do not store, use, and/or consume foods, beverages, tobacco products, or cosmetics in areas where this material is stored. Wash hands and face carefully before eating, drinking, using tobacco, applying cosmetics, or using the toilet. Wash exposed skin promptly to remove accidentally splashes of contact with this material. Maintain a sink, safety shower and eyewash fountain in the work area. Have oxygen readily available.
