PRIMARY ROUTE(S) OF ENTRY: Eyes, skin, ingestion. MOST IMPORTANT SYMPTOMS / EFFECTS, ACUTE AND DELAYED: GENERAL: to skin and eyes. Causes long term effects if inhaled EYE CONTACT: SKIN CONTACT: May be harmful to the unborn child if ingested Causes respiratory irritation, and long term effects with repeated exposure. CHRONIC SYMPTOMS: Long term inhalation of dust may cause Pneumoconiosis (Black lung disease), which causes shortness of breath that gets progressively worse and result in lung damage. If ingested, may cause reproductive harm. INDICATION OF ANY IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED, IF NECESSARY: If you experience any of the symptoms / effects listed above seek medical advice. SECTION 5: FIRE FIGHTING MEASURES EXTINGUISHING MEDIA: Use dry chemical powder, alcohol resistant foam, carbon dioxide SPECIFIC HAZARDS ARISING FROM THE SUBSTANCE OR MIXTURE: Emits toxic fumes under fire conditions. Product itself is not explosive, but if dust is generate, dust clouds suspended in air can be explosive. ADVICE FOR FIRE FIGHTERS: Wear self-contained breathing apparatus with full face piece operated in positive pressure mode and full body protective clothing. Use water spray to keep containers cool.
