SYNONYM REFERENCE
- (Budavari, 1996; HSDB , 2000; Lewis, 2000)
USES/FORMS/SOURCES
Carbon black is used as, among many other things, a pigment and conducting filler for inks, plastics, and paints; as a reinforcing agent for tire rubber and other elastomers; carbon paper, typewriter ribbons; nucleating agent in weather modification; expanders in battery plates; and as a solar energy absorber (ACGIH, 1991a; Hathaway et al, 1996a; HSDB , 2000; Lewis, 1997).
Several types of artificially prepared carbon or charcoal are designated by the term carbon black (Budavari, 1996): Animal charcoal - is prepared by charring bones, blood, meat, etc. Gas black, furnace black, channel black - is prepared by the incomplete combustion of natural gas. Lamp black - is prepared by the burning of fats, resins, or oils under ideal conditions. Activated charcoal - is obtained from wood and vegetables
"Carbon blacks are characterized as acetylene black, channel black, furnace black, lampblack or thermal black, according to the process by which they are manufactured. Lampblack is the oldest type of carbon black, having been used as a pigment for centuries. Channel black, produced from natural gas, was introduced in the late nineteenth century and was the major carbon black used worldwide in the early twentieth century for rubber and pigment applications; with the exception of a special product made in Germany, it is no longer produced. Acetylene, furnace and thermal blacks have been produced since the early twentieth century. Over 90% of all carbon black produced today is furnace black" (IARC , 1996). "Depending on the process of manufacture there are variations in the chemical composition of carbon black. It contains 88-99.5% of carbon; 0.3-11% of oxygen; 0.1-1% of hydrogen; up to 1% inorganic materials; small amount of tarry matter and traces of sulfur" (HSDB , 2000). Grades of carbon black include the following (HSDB , 2000): HAF (high abrasion furnace) FEF (fast extrusion furnace) SRF (semireinforcing furnace) HMF (high modules furnace) GPF (general purpose furnace) SAF (super abrasion furnace) ISAF (intermediate abrasion furnace) FF (fine furnace) XCF (electrically conductive furnace) APF (all-purpose furnace) FT (fine thermal) MT (medium thermal) MT-NS-FF (medium thermal, non-staining, free flowing)
A finely divided form of carbon, carbon black can be generated through the incomplete combustion of hydrocarbons in gaseous or liquid forms. Specific types of carbon black (furnace black or channel black) are formed by individual processes. Thermal black is produced by a cracking type process. Some of the other carbon blacks (lampblack, charcoal, etc.) are produced by processes involving bone or fats (ACGIH, 1991a; Budavari, 1996; Harbison, 1998; HSDB , 2000).
SYNONYM EXPLANATION
- Carbon black synonyms may vary based on the type (method of production) of carbon black compound designated (Budavari, 1996; IARC , 1996).
- No health hazards have been demonstrated in humans following acute exposure to carbon black. It has, however, been recognized as a possible carcinogen to humans.
-CLINICAL EFFECTS
GENERAL CLINICAL EFFECTS
- There are no well documented health hazards to humans from acute exposure to carbon black. Potential health effects are generally due to impurities adsorbed on its surface rather than to the carbon itself.
- Carbon black may be irritating to the skin and nose, mouth, throat and respiratory tract. Contact may cause burns to skin and eyes.
- POTENTIAL HEALTH HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 133 (ERG, 2004)
Fire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.
ACUTE CLINICAL EFFECTS
- The major route of occupational exposure to carbon black is inhalation, but there are no well-documented human health effects from acute exposure (Hathaway et al, 1991). Effects expected from acute exposure to carbon or carbon black are irritation of the eyes, nose, and respiratory tract at high-level exposures from frictional action.
CHRONIC CLINICAL EFFECTS
- Most research on the effects of chronic exposure to carbon or carbon black have focused on pulmonary effects, particularly pneumoconiosis and lung cancer. Chronic exposure to high levels of carbon black can cause an accumulation in the lung with chronic bronchitis and an obstructive-like condition (Kandt, 1985).
- In this form of pneumoconiosis, emphysema can sometimes also be present (ILO, 1983). However, there is usually little effect on pulmonary function (Wehr, 1975; Clayton & Clayton, 1994; Hathaway et al, 1991).
- Channel process carbon black was more fibrogenic than other types in a Russian study (Troitskaya, 1975). In one epidemiological study of carbon pneumoconiosis, all patients had smoked for at least 20 years (Ray, 1967), introducing a confounding factor.
- Carbon black had a minimal impact on pulmonary function of workers who smoked, but this group did have signs of obstructive airway disease more frequently than non-smoking workers. Exposure to fine dust had no effect on pulmonary function among nonsmokers and former smokers (Kupper et al, 1996).
- No significant increases in total mortality or mortality from heart disease were found in a retrospective study on 1,200 men exposed to carbon black from 1935 to 1974 (Hathaway et al, 1991).
- Carbon black can accumulate in the skin after chronic exposure, producing a tattooing effect called ANTHRACOSIS, consisting of black follicular dots (Capusan & Mauksch, 1969).
- A summary of major occupational studies on carbon black concluded that it acts like any other nuisance dust in its pure form. It can interact with disease states (tuberculosis) or other exposures (smoking, silica) to reduce pulmonary function or induce fibrosis (Clayton & Clayton, 1994).
- Inhalation exposure in hamsters, mice, guinea pigs, and monkeys had no effect (Nau, 1962), except that in monkeys there were ECG abnormalities indicating left ventricular cardiac hypertrophy (Nau, 1976). In mice exposed by inhalation, carbon black suppressed the immune response (15).
- Rats exposed to 7.1 or 52.8 mg/m(3) carbon black for up to 13 weeks showed inflammation in the lung, increased chemokine expression, epithelial hyperplasia, and pulmonary fibrosis (Driscoll et al, 1996).

SUMMARY
- FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 133 (ERG, 2004)
Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Removal of solidified molten material from skin requires medical assistance. Keep victim warm and quiet. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
FIRST AID EYE EXPOSURE - Promptly wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention if any discomfort continues. Contact lenses should not be worn when working with this chemical. However, as recommended by the Occupational Safety and Health Administration (OSHA), individuals who wear contact lenses in the workplace must combine them with appropriate industrial safety eyewear. INHALATION EXPOSURE - Move the exposed person to fresh air at once. Other measures are usually unnecessary. TARGET ORGANS - Respiratory system and eyes (National Institute for Occupational Safety and Health, 2007; OSHA, 2000).
INHALATION EXPOSURE - INHALATION: Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with an inhaled beta2-adrenergic agonist. Consider systemic corticosteroids in patients with significant bronchospasm.
DERMAL EXPOSURE - DECONTAMINATION: Remove contaminated clothing and jewelry and place them in plastic bags. Wash exposed areas with soap and water for 10 to 15 minutes with gentle sponging to avoid skin breakdown. A physician may need to examine the area if irritation or pain persists (Burgess et al, 1999). If clothing is contaminated, wet the clothing to keep down the dust. Do not shake or blow dust off clothing or the body.
EYE EXPOSURE - DECONTAMINATION: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, the patient should be seen in a healthcare facility.
ORAL EXPOSURE - Have the victim rinse mouth several times with cold water and spit out. DILUTION: If no respiratory compromise is present, administer milk or water as soon as possible after ingestion. Dilution may only be helpful if performed in the first seconds to minutes after ingestion. The ideal amount is unknown; no more than 8 ounces (240 mL) in adults and 4 ounces (120 mL) in children is recommended to minimize the risk of vomiting.
-RANGE OF TOXICITY
MINIMUM LETHAL EXPOSURE
CARCINOGENICITY -- According to the International Agency for Research on Cancer (IARC), evidence for the carcinogenicity of carbon black in humans is inadequate; evidence is sufficient for the carcinogenicity of carbon black and carbon black extracts in experimental animals. IARC's overall evaluation is to classify this compound as a 2B - possibly carcinogenic to humans - carcinogen (IARC, 2000). Lewis (2000) states that although tiny particulates of carbon black may contain carcinogenic material, the carcinogens are held too tightly to be eluted by water, blood plasma, or gastric juices.
MAXIMUM TOLERATED EXPOSURE
No health hazards have been well demonstrated for acute exposure of carbon black to humans (Hathaway et al, 1996). Organic impurities adsorbed to the surface of this compound are usually responsible for the potential health effects associated with carbon black (Hathaway et al, 1996). "A significant loss in pulmonary function was reported in a group of 125 Nigerian carbon-black workers exposed to levels of up to 34 mg/m(3). The most common respiratory symptom was cough with phlegm, but radiograms were normal. Significant annual declines were reported in another group of 35 workers exposed to concentrations of less that 10 mg/m(3). In contrast, a survey of over 500 carbon-black workers in the United States and in the United Kingdom found no statistical difference in spirometry, chest radiograph, physical examination, or repeated symptoms" (Hathaway et al, 1996). "Sixteen healthy subjects, including 11 smokers, were exposed in an environmental chamber for a 5-hr period to Xerox toner, carbon black, at total dust levels of 2, 10, and 25 mg/m(3). The latter two exposures are almost three and six times the threshold limit value (TLV), respectively, for carbon black. Nasal mucociliary clearance rate and nasal resistance were unaffected. The forced expiratory volume in 1 second decreased at all dust concentrations while the forced vitality capacity (FVC) and forced expiratory flow remained unchanged. Discomfort, manifested as dryness in the nose and pharynx, was not excessive, was proportional to the dust concentration, and lagged the changes in dust concentration for almost 2 hr" (HSDB , 2000).
No malignancies or other significant effects were observed in any of five species of animals exposed for prolonged periods of time, 7 hours/day, 5 days/week to dust concentrations of either 84.7 mg/m(3) of channel black or 56.5 mg/m(3) of furnace black (ACGIH, 1991).

-HANDLING AND STORAGE
SUMMARY
HANDLING
- Safety glasses should be worn when handling this compound (ITI, 1995).
STORAGE
Store carbon black so that it does not come into contact with bromates, chlorates, and nitrates. Prohibit smoking, open flames, and other sources of ignition where carbon black is handled, used, or stored to decrease potential fire or explosion hazards. Use, store, and handle carbon black containing more than 0.1% polycyclic aromatic hydrocarbons (PAHs) in a regulated area as a carcinogen (Sittig, 1991).
Carbon black is incompatible with bromates, chlorates, nitrates, and other strong oxidizers (NIOSH , 2000; Sittig, 1991).
-PERSONAL PROTECTION
SUMMARY
- RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 133 (ERG, 2004)
- Skin contact with carbon black should be avoided by wearing appropriate protective clothing, footwear, gloves, headgear, suits, and barrier creams that are resistant to carbon black penetration. This clothing should be provided by the employer, have elastic cuffs at the wrists and ankles, be clean, and be put on before each workday (HSDB , 2000; Sittig, 1991).
- Remove clothing contaminated with carbon black immediately and place in storage containers prior to disposal or cleaning. The individual cleaning the clothing should be made aware of the hazardous properties of carbon black. Check reusable clothing or equipment for contamination prior to reuse or storage. Wash thoroughly before smoking, eating, using toilet facilities, and before leaving work premises (HSDB , 2000).
- "Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants" (HSDB , 2000).
EYE/FACE PROTECTION
- When working with carbon black powders or dust, dust-proof goggles (or full facepiece respiratory protection) should be worn (Sittig, 1991).
- Do not wear contact lenses (HSDB , 2000).
RESPIRATORY PROTECTION
- Refer to "Recommendations for respirator selection" in the NIOSH Pocket Guide to Chemical Hazards on TOMES Plus(R) for respirator information.

CONTAINMENT/WASTE TREATMENT OPTIONS
SPILL OR LEAK PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 133 (ERG, 2004) ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch or walk through spilled material.
RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 133 (ERG, 2004) Those persons not wearing appropriate protective equipment should be restricted from the spill area until cleanup is complete. All ignition sources should be removed from the area of the spill. Powdered material should be collected in a convenient and safe manner and deposited in sealed containers (Sittig, 1991). Sittig (1991) suggests landfill disposal or slurry incineration. "If carbon black is spilled or leaked, the following steps should be taken: Remove all ignition sources. Ventilate area of spill or leak. Carbon black dust may be collected by vacuuming with an appropriate high efficiency filtration system or by using wet methods; it should then be placed into in an appropriate container. If a vacuum system is used, there should be no sources of ignition in the vicinity of the spill, and flashback prevention devices should be provided" (HSDB , 2000). If dusty conditions are anticipated, workers should be supplied with respiratory protection to wear while cleaning up spills. When appropriate, wet methods or vacuum cleaning can be used to remove the last traces of dust from the area (Clayton & Clayton, 1994).
-ENVIRONMENTAL HAZARD MANAGEMENT
