' Maierr j&afety Data Sheets Coiiection GenluAbllshlrlg Corporation 1145 Catalyn Street Sheet No. 470 Schenectady,NY 12303-1836 USA Diesel Fuel Oil No 2-D (518)377-8854 t Issued 10181 Revision A, 11190 Section 1. Material ITentificatlon 33 Diesel Fuel Oil No 2-D Description Diesel fuel is obtained from the middle distillate in petroleum separation,a distillate l NFPA Oil of low sulfur content.It is composed chiefly of unbranched paraffins Diesel fuel is available in vanous grades,one of I 2 which is synonymous with fuel oil No 2-D This diesel fuel oil requires a minimum Cetane No (efficiency rating for S 2 0 0 ' diesel fuel comparable to octane number ratings for gasoline)of 40(ASTM D613) Used as a fuel for trucks,ships,and - other automotive engines,as mosquito control(coating on breeding waters),and for drilling muds Other Designations CAS No 68334-30-5,diesel fuel HMIS Manufacturer Contact your supplier or distributor Consult the latest Chemicalweek Buyers Guide(13)for a suppliers list. F 2 R 0 Cautions Diesel fuel oil No 2-D is a skin untant and central nervous depressant with high mist concentrations Itis an environmental PPG* hazard and moderate fire risk, •Sec 8 ' Section 2. ln�!redients and Occupational Exposure Limits Diescl fuel oil No 2-D• , 1989 OSHA PEL 1990-91 ACGIH TLV 1988 NIOSH REL 1985-86 Toxicity Data$ None established Mineral Oil Mist None established Rat, oral,LD,, 9 g/kg produces gastrointestinal (hypermouhty,diarrhea) ' TWA 5 mglm't effects STEL 10 mg/ml Dicscl fuel No 2-D tends to be low in aromatics and high in paraffinics This fuel oil is complex mixture of 1)x95%paraffinic,olefinie,naphthemc,and aromatic hydrocarbons 2)sulfur(<0.5%),and 3)benzene(<100 ppm) [A low benzene level reduces carcinogenic nsk.Fuel oils can be exempted under the benzene standard(29 CFR 1910 1028)] Although low in the fuel itself,benzene concentrations arc likely to be much higher in processing areas ' t As sampled by nonvapor-collecting method J- t Monitor MASH,RTECS(HZ1800000),for future toxicity data Section 3.
