Health hazards

WARNING! CAUSES EYE, SKIN AND RESPIRATORY TRACT IRRITATION. MAY BE HARMFUL IF SWALLOWED.E

Principle Routes of Exposure

Inhalation and skin contact.

Potential health effects

Carbon Inhalation and skin contact are expected to be the primary routes of occupational exposure to activated carbon. Based on its similarity to graphite, contact with skin and eyes to excessive dust levels may cause irritation from mechanical abrasion. Short- term overexposure to dusts may cause upper respiratory tract irritation. Chronic overexposure to graphite dusts in mining, milling, and electrode production operations has caused pneumoconiosis, characterized by increased lung fibrosis, shortness of breath, cough, and abnormal breathing. Coke (petroleum) Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. Dust may be severely irritating to eyes and respiratory tract.

Medical Conditions Generally Aggravated by Exposure

to this material include lung disease or limited respiratory capacity. I Corrosion Engineering Rev. 4.000 01/13/2 1 of 7 Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. Based on single exposure animal tests, it is considered to be slightly toxic if swallowed, severely irritating to eyes and corrosive to skin. Vapor may cause respiratory tract irritation including coughing, tightness in chest, dizziness and, at very high levels, lung edema (accumulation of fluid in the lungs) which may be delayed for several hours. If swallowed, this material may cause mild to severe burns to the mouth, throat and digestive tract. This material is considered hazardous by the OSHA Hazard Communication Standard (29 CFR 1910.1200). See Section 11 for additional toxicological information.
