Brownish to black, thick liquid/semisolid substance with naphthalene-like odor; [HSDB] 0-2% benzene, toluene, & xylene; 16-18% phenols, cresols, & naphthalene; 8-10% naphthalene derivatives; 16-20% anthracene oils; and 50% pitch; [CHEMINFO MSDS]
Used in surface coatings and sealants (walls, insulation, pipes, roofs, and roads); Used to produce plastics, solvents, dyes, and drugs for psoriasis; Used as a fuel in open hearth furnaces in the steel industry; [HSDB]
May cause first degree burns after short exposure and second degree burns after longer contact; [CHRIS] NIOSH considers coal tar, coal tar pitch, and creosote to be coal tar products. Wood creosote (8021-39-4) is derived from the distillation of beechwood tar; it is yellow, transparent, and chemically distinct from coal tar creosote. [ATSDR ToxProfiles] Chronic exposure to coal tar and its vapors is associated with an increased risk for cancer of the lungs, kidneys, skin, and bladder. Coal tar is a potential photosensitizer. [CHEMINFO MSDS] Coal tar creosote (8001-58-9) and Coal tar pitch volatiles 65996-93-2) are covered separately. Coal-tar pitch is classified as 1 (IARC) and K (NTP); [Guide to Occupational Exposure Values] See "Coal-tar distillation."
For occupational exposure limits, see "Coal tar pitch volatiles."
