11. Toxicological information
EFFECTS OF OVEREXPOSURE - EYE CONTACT: May cause eye irritation. Extremely irritating to the eyes and may cause severe
damage, including blindness. Substance causes severe eye irritation. Injury may be permanent. Irritating, and may injure eye tissue
if not removed promptly.
EFFECTS OF OVEREXPOSURE - SKIN CONTACT: May cause severe irritation. May cause dryness, cracking, irritation, and
chemical burns. May produce cement dermatitis due to primary irritation from alkaline, hygroscopic, and abrasive properties. May
cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Low hazard for usual
industrial handling or commercial handling by trained personnel.
EFFECTS OF OVEREXPOSURE - INHALATION: High vapor concentrations are irritating to the eyes, nose, throat and lungs. Avoid
breathing fumes, spray, vapors, or mist. High gas, vapor, mist or dust concentrations may be harmful if inhaled.
EFFECTS OF OVEREXPOSURE - INGESTION: May cause obstruction in stomach, as it hardens with moisture. Symptoms include
stomach pain, distress. Drinking glycerin, gelatin solutions, or large volumes of water may delay the hardening of calcium sulfate in
the stomach. Surgical relief of obstruction, particularly at the pylorus, may be necessary. Substance may be harmful if swallowed.
Expected to be a low ingestion hazard.
EFFECTS OF OVEREXPOSURE - CHRONIC HAZARDS: Contains carbon black. Chronic inflammation, lung fibrosis, and lung
tumors have been observed in some rats experimentally exposed for long periods of time to excessive concentrations of carbon black
and several insoluble fine dust particles. Tumors have not been observed in other animal species (i.e., mouse and hamster) under
similar circumstances and study conditions. Epidemiological studies of North American workers show no evidence of clinically
significant adverse health effects due to occupational exposure to carbon black.
Carbon black is listed as a Group 2B-"Possibly carcinogenic to humans" by IARC and is proposed to be listed as A4- "not classified
as a human carcinogen" by the American Conference of Governmental Industrial Hygienists. Significant exposure is not anticipated
during brush application or drying. Risk of overexposure depends on duration and level of exposure to dust from repeated sanding of
surfaces or spray mist and the actual concentration of carbon black in the formula. Reports have associated repeated and prolonged
occupational overexposure to solvents with permanent brain and nervous system damage.
PRIMARY ROUTE(S) OF ENTRY: Eye Contact, Ingestion, Inhalation, Skin Absorption, Skin Contact
