Coal tar pitch volatiles. Quantitative levels of coal tar pitch volatiles .
Coal tar pitch volatiles : Biological exposure limit for occupational exposure to coal tar pitch volatiles at cokeovens. Petroleum asphalt removed from coverage under the Coal Tar Pitch Volatiles Standard (April 08, 1983). Coal tar pitch volatiles are compounds given off from coal tar pitch when it is heated. 0 Approximately half of the cohort had ever been exposed to coal tar pitch volatiles. Exposure to coal tar pitch volatiles occurs within the potrooms, potlining, potshell repair, and the anode plant. 1000 (Table Z-1), coal tar pitch volatiles include the fused polycyclic hydrocarbons which volatilize from the distillation residues of coal, petroleum (excluding asphalt), wood, and other organic matter. 63(8):511-516, 1992. 1972]; however, no studies have been made on carcinogenic effects by any route from single short-term exposure to CTPV that could relate to a 30-minute IDLH. 2 mg/m 3, as Benzene Solubles. March 2002. Workers in casting, wharf, power operations, and administration departments have minimal exposure. Asphalt (CAS 8052-42-4, and CAS 64742-93-4) is not covered See full list on nj. Once the pitch is heated, chemicals vaporize and may be inhaled by workers. COAL TAR PITCH VOLATILES. No more recent occupa-tional exposure surveys were found. OSHA Method 58 specifies the collection of particulates using a glass fibre filter (GFF) and the gravimetric determination of the benzene-soluble fraction (BSF). SAMPLING SAMPLER: FILTER (2-µm, 37-mm PTFE membrane) FLOW RATE:1 to 4 L/min VOL-MIN: 500 L @ 0. Coal tar pitch volatiles (CTPVs) are found in the industry when heating of coal tar or coal tar pitch takes place. Applicability of the Coal Tar Pitch Volatiles Standard to dust of coal tar pitch (May 17, 1982). Coal tar pitch is a black or dark-brown amorphous residue produced by the distillation or heat treatment of coal tar. Acridine, Anthracene, Benzo(a)pyrene, Chrysene, Coal tar, Phenanthrene, pyrene [Note: NIOSH considers coal tar, coal tar pitch, and creosote to be coal tar products. NIOSH: Occupational Health Guideline for Coal Tar Pitch Volatiles. ] Black or dark-brown amorphous residue. National Institute for Occupational Safety and Health (NIOSH) Publication No. Overview Coal tar pitch volatiles (CTPVs) are composed of various chemical vapors that become airborne during the heating of coal tar pitch. 1978; NIOSH/CEC/IPCS: International Chemical Safety Cards - Coal Tar Pitch. 5. 81-123, (January 1981). Coal tar is obtained by the distillation of bituminous coal (Ref. 1002 Coal tar pitch volatiles; interpretation of term. of coal for the production of coke (Ref. 2 mg/m3-MAX: 2400 L SHIPMENT: routine SAMPLE STABILITY: unknown BLANKS: 2 to 10 field blanks per set MEASUREMENT TECHNIQUE: GRAVIMETRIC Natural or mined asphalts do not fall within the scope of the Coal Tar Pitch Volatiles Standard (May 26, 1983). Other animal data: The major health effects resulting from longterm repeated exposure to coal tar pitch volatiles (CTPV) are cancer of the lung, kidney, and skin [Redmond et al. 3). gov to coal-tar-pitch volatiles (NIOSH 1990). coal tar pitch volatiles Benzene soluble particulate matter should not be attributed to coal tar pitch volatiles unless polynuclear aromatic hydrocarbons (PNAHs) are present. Jongeneelen, F. As used in § 1910. 1972]; however, no studies have been made on carcinogenic effects by any route from single shortterm exposure to CTPV that could relate to a 30minute IDLH. Coal tar pitch is similar in composition to coal tar creosote and is not presented separately. Coal tar pitch volatiles; Coke oven emissions; Occupational Health Guidelines for Chemical Hazards. (Ref. Workers potentially exposed to coal-tar pitches include those pro-ducing or using pavement tar, roofing tar, coal-tar pitch, coal-tar paints, coal-tar enamels, other coal-tar coatings, or refractory bricks. The volatile component is not shown separately because it. TLV–TWA, 0. This was used to spike filters approximating a Coal Tar Pitch Volatile sample. Evaluating Exposure Coal tar pitch volatiles (CTPVs) are measured by passing workplace air through a sampling device and then analyzing the sample for the compounds of interest. A portion of the "dried" tar was used to prepare a stock solution in benzene. A1 — Confirmed Human Carcinogen. Coal tar pitch is composed almost entirely of polynuclear aromatic compounds and constitutes 48-65% of the usual grades of coal tar. To view TLV and Documentation, you must be logged in as an ACGIH member or have previously purchased the documentation. CAS number: 65996-93-2. Int Arch Occup Environ Health. Quantitative levels of coal tar pitch volatiles As used in § 1910. 2). ). 2. 3. § 1910. 3) The purpose of this work was to evaluate the sampling and analytical method routinely The solution was concentrated with a stream of dry nitrogen and the gooey tar was placed in a heated oven (60°C under 20 in. The purpose of this work was to evaluate the sampling and creosote, coal tar creosote, and coal tar is provided in Tables . coal for the production of coke (Ref. SYNONYMS: benzene-solubles, cyclohexane-solubles, coal tar pitch volatiles, creosote from coal tar. The following references aid in evaluating levels of CTPVs. Industries where workers are potentially exposed to CTPVs include coking, roofing, road paving, aluminum smelting, wood preserving and any others where Other animal data: The major health effects resulting from long-term repeated exposure to coal tar pitch volatiles (CTPV) are cancer of the lung, kidney, and skin [Redmond et al. Hg vacuum) for 4 h. 4-1 through 4-3. Coal tar pitch is composed almost entirely of polynuclear aromatic compounds and constitutes 48-65% of the usual grades of coal tar (Ref. Asphalt (CAS 8052-42-4, and CAS 64742-93-4) is not covered under the "coal tar pitch volatiles" standard. rurdwrcyyjofhjykfkcueukhwuidlnacptuyyhosjqyffudzudxasexdmwp
