Because petro leum produot tanks are always a source of hazard to the men entering them for any purpose, work of this sort should not "be done unnecessarily. The nature of these hazards is quite veil understood by the petroleum industry generally. Instructions for preventing accidents to nan working in or around tanka are obtainable from the American Petroleum Institute and through many petroleum covnanies. Any tank that ha-, contained leaded fuel may offer serious danger of exposure. This danger la due to volatile organic lead compounds in the sludge, and to the presence of these compounds in the scale a a veil. A further danger exists from the inorganic ieed compounds in the water bottoms and sludge re sulting from treating operations other than tetraethyl lead* IT J APFABSST, TK?IRSrORa, THAT DO TAJdC TIOJT) ?Q?\ Lj SADBD GASPLI DO MAY 2i A35CKS3 TO 12. 7?i:- A LBAD HAZARD. (This applies with equal force in the case of refinery, terminal, bulk, trackside or any other tank which is en tered for cleaning or repair.) If hazards are to be avoided, the following precautions must be taken whenever tardea that have contained loaded gasoline are entered for any purpose: (l) A blover-typ,e or positive-pressure airline hosear.sk should be worn by any person who enters a leaded gasoline tank that has not been thoroughly cleaned. This applies not only to tank cleaners but to all others who go into the tank for any purpose. \2) Roselines for air masks have a limited life and must be kept clean. If a workman notices any odor, ns of gasoline, while wearing his mask* he must leave the tank at once and find the cause or get a new hoaeline.
