Section 3: Hazards Identification
Potential Health Effects Eye Contact: High dust concentrations may cause mechanical irritation to eye.

Skin Contact: No evidence of adverse effects from available data. No cases of sensitization in humans have been reported.

Inhalation: Temporary discomfort to upper respiratory tract may occur due to mechanical irritation when exposures are above the occupational exposure limit.

Ingestion: No evidence of adverse effects from available data.

Subchronic/Chronic Hazards: IARC listed; Group 2B (possibly carcinogenic to humans). See Section 11.

General: There are no known human carcinogenic effects related to the Polycyclic Aromatic Hydrocarbons (PAH) content of carbon blacks. See Section 16.
Section 4: First Aid Measures
After Skin Contact Wash from skin with mild soap and water. Seek medical attention, if irritation occurs.
After Eye Contact Gently flush eyes with water until all foreign matter is completely removed keeping eyelids open. Seek medical attention, if irritation develops or persists.
After Inhalation Remove affected person to fresh air and consult physician. If breathing is difficult, give oxygen. If unconscious, evaluate the need for artificial respiration. Get immediate medical attention.
After Ingestion Do not induce vomiting. If conscious, rinse mouth with water.
Section 5: Fire Fighting Measures
Flash Point Not determined
OSHA Flammability Classification None
Auto-Ignition Temperature Not determined
Fire/Explosion Hazards Dusts at sufficient concentrations can form explosive mixtures with air.
Auto-Ignition Temperature (transport) >284° F. (>140° C.)
Extinguishing Media Use water spray or fog, foam, dry chemical or CO2. Avoid high pressure water stream as this may spread burning powder (burning powder will float). A fog spray is recommended, if water is used.

Note: It may not be obvious that carbon black is burning unless the material is stirred and sparks are apparent. Carbon black that has been on fire should be observed closely for at least 48 hours to ensure no smoldering material is present.
Fire Fighting Procedure Wear full protective fire fighting gear including self-contained breathing apparatus (SCBA).
Hazardous Thermal
Decomposition Byproducts		 Products of combustion include carbon monoxide (CO), carbon dioxide (CO2), and oxides of sulfur.
Section 6: Accidental Release Measures
Spill Procedures Scoop up dry material and use vacuum for residue.

Note: Wet carbon black produces dangerously slippery walking surfaces.
Containment Techniques Small spills should be vacuumed when possible. A vacuum equipped with HEPA (high efficiency particulate air) filtration is recommended. Alternatively, light water spray will reduce dust for dry sweeping.

Large spills may be shoveled into containers. See Section 13. Wear appropriate personal protective equipment and respiratory protection. See Section 8.

Carbon black poses no significant environmental hazards. As a matter of good practice, minimize contamination of sewage water, soil, groundwater, drainage systems, or bodies of water.
Spill Response Equipment The following equipment is recommended for spill response:
• vacuum equipped with HEPA filtration
• dustpan, shovel or scoop
• bags, drums, or sacks for collection
Section 7: Handling and Storage
Handling Avoid dust exposures above the occupational exposure limit. Wash exposed skin daily.

Use local exhaust ventilation to control exposures to below occupational exposure limit.

Fine dust may cause electrical shorts and is capable of penetrating electrical equipment unless tightly sealed.

If hot work (welding, torch cutting, etc.) is required the immediate work area must be cleared of carbon black product and dust.
Storage Store away from ignition sources and strong oxidizers.

Before entering closed vessels and confined spaces containing carbon black test for adequate oxygen, flammable gases and potential toxic air contaminants (e.g., CO). Follow safe practices when entering confined spaces.
Section 8: Exposure Controls / Personal Protection
Engineering Controls Use process enclosures and/or exhaust ventilation to keep airborne dust concentrations below the occupational exposure limit.
General Hygiene Practices Wash hands and face thoroughly with mild soap before eating and drinking. Frequent skin washing may dry skin. Application of a skin lotion is recommended.
Respiratory Protection An approved air-purifying respirator (APR) may be used where airborne concentrations are expected to exceed occupational exposure limits. Protection provided by APRs is limited. Use a positive-pressure, air supplied respirator if there is any potential for uncontrolled release, exposure levels are not known, or any circumstances where air-purifying respirators may not provide adequate protection. Use of respirators must be accompanied by a complete respiratory protection program in accordance with national standards and current best practices.

The following agencies/organizations approve respirators and/or criteria for respirator programs:

U.S.:
NIOSH approval under 42 CFR 84 required.

Section 11: Toxicological Information
Acute Toxicity Ingestion: LD50 (rat), >8000 mg/kg
Primary Irritation:
Skin (rabbit), non-irritative, index score 0.6/8 (4.0 = severe edema)
Eye (rabbit), non-irritative, Draise score 10-17/110 (100 = maximally irritating)
Sensitization: no animal data available.
Subchronic Toxicity Rat, inhalation, duration 90 days
Target organ: Lungs
Effect: Inflammation, hyperplasia, fibrosis NOAEL = 1.1 mg/m3 respirable
Chronic Toxicity Rat, inhalation, duration: 2 years
Target organ: Lungs
Effect: Inflammation, fibrosis, tumors

Note: Tumors in the rat lung are related to the fine particle overload phenomenon rather than to a specific chemical effect of the dust particles in the lung. These effects in rats have been reported in studies on other inorganic insoluble particles and appear to be species specific. Tumors have not been observed in other species (i.e., mouse and hamster) for carbon black under similar circumstances and study conditions.
Carcinogenicity Rat, oral (feeding experiments), duration: 2 years, no tumors (literature)
Mouse, oral (feeding experiments), duration: 2 years, no tumors (literature)
Mouse, dermal, duration: 12-18 months, no skin tumors (literature)

Authoritative body classification:
In 1995, IARC concluded, "There is inadequate evidence in humans for the carcinogenicity of carbon black." Based on rat inhalation studies IARC concluded that there is, "sufficient evidence in experimental animals for the carcinogenicity of carbon black." IARC's overall evaluation in 1995 was that, "Carbon black is possibly carcinogenic to humans (Group 2B)." This conclusion was based on IARC's guidelines that require such a classification if one species exhibits carcinogenicity in two or more studies.

In its 1987 review, IARC concluded, "There is sufficient evidence in experimental animals for the carcinogenicity of carbon black extracts." Carbon black extracts are classified as, possibly carcinogenic to humans (Group 2B). Carbon black is not designated a carcinogen by the U.S. National Toxicology Program (NTP) or the U.S. Occupational Safety and Health Administration (OSHA). The American Conference of Governmental Industrial Hygienists classifies carbon black as A4, Not Classifiable as a Human Carcinogen.

The U.S. National Institute of Occupational Safety and Health (NIOSH) 1978 criteria document on carbon black recommends that only carbon blacks with Polycyclic Aromatic Hydrocarbon (PAH) levels greater than 0.1% require the measurement of PAHs in air. As some PAHs are possible human carcinogens, NIOSH recommends an exposure limit of 0.1 mg/m3 for PAHs in air, measured as the cyclohexane-extractable fraction.

Mutagenic effects:
Because carbon black is not soluble or dispersible in aqueous systems testing in bacterial and other in-vitro systems should be conducted using DMSO.

In an experimental investigation, mutational changes in the hprt gene were reported in alveolar epithelial cells in the rat following inhalation exposure to carbon black. This observation is believed to be rat specific and a consequence of "lung overload" (see Chronic Toxicity above).

Reproductive effects: No effects have been reported in reproductive organs in long term animal studies.
Epidemiology Results of epidemiological studies of carbon black production workers suggest that cumulative exposure to carbon black may result in small decrements in lung function, as measured by FEV1. A recent U.S. respiratory morbidity study suggested a 27 ml decline in FEV1 from a 1 mg/m3 (inhalable fraction) exposure over a 40-year period. An older European investigation suggested an exposure to 1 mg/m3 (inhalable fraction) of carbon black over a 40-year working-lifetime will result in a 48 ml decline in FEV1. In contrast, normal age related decline over a similar period of time would be approximately 1200 ml.

The relationship between symptoms and exposure to carbon black is less clear. In the U.S. study, 9% of the highest exposure group (in contrast to 5% of the unexposed group) reported symptoms consistent with chronic bronchitis. In the European study, methodological limitations in the administration of the questionnaire limit drawing of definitive conclusions about symptoms. This study, however, indicated a link between carbon black and small opacities on chest films. with negligible effects on lung functions. A study of carbon black workers in the UK showed an elevated incidence of lung cancer but it was not considered to be related to carbon black.

Section 16: Other Information
Miscellaneous Manufactured carbon blacks generally contain less than 0.1% of solvent extractable polycyclic aromatic hydrocarbons (PAH). Solvent extractable PAH content depends on numerous factors including, but not limited to, the manufacturing process, desired product specifications, and the analytical procedure used to measure and identify solvent extractable materials. Questions concerning PAH content of carbon black and analytical procedures should be addressed to your carbon black supplier. The carbon black industry continues to sponsor research designed to identify adverse health effects from long term exposure to carbon black.
