Section II. Composition and Information on Ingredients

• Material

• Ammonium Dichromate

Section III Hazards Identification:

• Accute Health Effects:  Irritating to the skin and eyes on contact. Inhalation will cause irritation to the lungs and mucus membrane. Irritation to the eyes will cause watering and redness. Reddening, scaling, and itching are characteristics of skin inflammation. Follow safe industrial hygiene practices and always wear protective equipment when handling this compound. Inhalation of dichromate dusts can also cause ulceration and perforation of the nasal septum. Contact with breaks in the skin can cause ulceration (chrome sores). Other symptoms of exposure include erosion and discoloration of the teeth, nephritis, epigastria pain(Inflammation and ulceration of the gastrointestinal tract).
• Chronic Health Effects:  Carcinogen. May alter genetic material.
• Accute Health Effects:  This product is not listed by NTP, IARC or regulated as a Carcinogen by OSHA.

Section IV. First Aid Measures

• First Aid For Eye:  In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a physician.
• First Aid For Skin:  In case of contact, flush skin with water. Wash clothing before reuse. Call a physician if irritation occurs.
• First Aid For Inhalation:  If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
• First Aid For Ingestion:  If swallowed, call a physician immediately.
