Wettable Cement Black

SECTION 2: Hazards identification

EMERGENCY OVERVIEW ********************************** Solid black powder with little to no odor. Inhalation can cause temporary lung irritation. May ignite in air above 500ºF. Will burn in fire. Carbon monoxide and carbon dioxide are emitted. It may not be obvious that product is burning unless it is stirred and sparks are apparent. Packaging material can burn or melt in fire, producing toxic smoke and fumes. *************************************************************************************************************************************

HMIS CODES

H=0, F=1, R=0, P=0 (0=Minimal, 1=Slight, 2=Moderate, 3=Serious, 4=Severe)

Potential health effects

Eyes: Non-irritating to the eyes. Excessive exposure to airborne dust may reduce visibility and/or cause unpleasant deposits. Skin: Will not irritate skin and is not likely to cause allergic skin reaction. Irritation to skin or mucous membranes can occur by direct mechanical action or by rigorous skin cleaning necessary for removal of dust. Ingestion: Small amount (less than one ounce/30 grams) swallowed is not likely to cause injury. If large amount ingested, may cause gastric irritation, nausea and diarrhea. Seek medical attention. Inhalation: Not a hazard in normal industrial use. As with all dusty materials, inhalation may cause respiratory irritation, sneezing, coughing, and runny nose. Human Effects and symptoms of overexposure: Acute: Dust concentrations above the permissible exposure limit may cause temporary upper respiratory tract discomfort. Chronic: Epidemiological studies of workers in the Carbon Black pigment producing industries of North America and Western Europe show no significant adverse health effect due to occupational exposure to Carbon Black pigment. Early studies in the former USSR and Eastern Europe report respiratory diseases among workers exposed to Carbon Black pigment, including bronchitis, pneumonia, emphysema, and rhinitis. Such studies are of questionable validity, due to inadequate study design and methodology, lack of appropriate controls for cigarette smoking, and other confounding factors such as concurrent exposures to carbon monoxide, coal oil and petroleum vapors. Moreover, review of these studies indicates that concentrations of Carbon Black pigment were greater than current occupational exposure standards. In Monograph 65, issued in April 1996, the International Agency for Research on Cancer (IARC) re-evaluated Carbon Black pigment and concluded that: “Although one cohort study on the Carbon Black pigment production industry showed slight excesses of cancer, the totality of the epidemiology studies, both in the Carbon Black pigment production industry and in some user industries, suggested that there is inadequate evidence for the carcinogenicity in humans of Carbon Black pigment." Other Effects: None known. Medical Conditions None known. Carbon Black pigment, like any nuisance dust, may aggravate certain pre-existing upper Aggravated by Exposure: respiratory disorders, such as bronchitis or asthma. Carcinogenicity: IARC: Listed Group 2B/Possible Human Carcinogen NTP: Not Listed OSHA: Not Listed Other: The IARC changed the listing of Carbon Black pigment April 12, 1996 from Category 3 (insufficient evidence to make a determination) to Category 2B (Known animal carcinogen/possible human carcinogen) based on the results of rat inhalation studies of Carbon Black pigment, despite the lack of any parallel evidence in humans or other animal species.
