V. HUMAN HEALTH DATA

ROUTE(S) OF ENTRY

 Eyes, Skin, Inhalation and Ingestion
INHALATION May cause severe burns or deep ulcerations of respiratory tract. Inhalation of high concentrations can result in permanent lung damage.
INGESTION Irritation and/or burns may occur to entire gastrointestinal tract, characterized by nausea, vomiting, diarrhea, abdominal pain.
SKIN CONTACT May case severe burns or deep ulcerations. Prolonged skin exposure can cause destruction of dermis with impairment of the skin at site of contact to regenerate.
EYE CONTACT May cause severe burns or deep ulcerations. Contact may cause impairment of vision and corneal damage.
CHRONIC EXPOSURE Prolonged skin exposure is similar to similar exposure. Prolonged inhalation may cause impairment of lung function and permanent damage.
AGGRAVATION OF PRE-EXISTING CONDITIONS Asthma and respiratory and cardiovascular disease.
CARCINOGENICITY Not listed by NTP, IARC or regulated as a carcinogen.


VI. FIRST AID
INHALATION Remove to fresh air. Call a physician. If breathing is difficult, give oxygen. If not breathing, give artificial respiration.
INGESTION If swallowed call a physician. If person is conscious, immediately drink large quantities of water. *****DO NOT INDUCE VOMITING*****
SKIN CONTACT In case of contact with skin, wash skin with soap and water. Wash clothing before reusing. Call a physician if irritation persists.
EYE CONTACT Immediately flush eyes with running water for 15 minutes. Call a physician.


VII. EMPLOYEE PROTECTION RECOMMENDATIONS
EYE PROTECTION Use chemical safety goggles. Do not wear contact lens if airborn dust is present.
SKIN PROTECTION Use chemically resistent gloves and clothing. Wash face and hands before eating or drinking.
PERSONAL RESPIRATORS Use a NIOSH/MSHA approved dust respirator.
VENTILATION SYSTEM Use local exhaust if dust concentration exceeds nuisance exposure limit or if worker discomfort exists.
ADDITIONAL MEASURES Prolonged skin exposure is similar to similar exposure. Prolonged inhalation may cause impairment of lung function and permanent damage.
