At THOUGH THE INTEGRITY (holes, etc. ) OF THE TANKS WAS GOOD, PETROLEUM HYDROCARBONS HAVE BEEN DETECTED IN THE SOIL DURING THE TANK REMOVAL.

THE LOWER EXPLOSION LIMIT (LEL) OF GASOLINE VAPOR IS 1.3 PERCENT IN AIR. IF THE [ t' CONCENTRATION OF GASOLINE VAPOR IN AIR EXCEEDS 1.3 PERCENT (13,U3. PARTS PER MILLION) AND SUFFICIENT QUANTITIES OF OXYGEN ARE PRESENT, THEN THE INTRODUCTION OF SUFFICIENT HEAT, SPARK, OR FLAME WILL RESULT IN AN EXPLOSION. A LESSER KNOWN HEALTH HAZARD RESULTING FROM EXPOSURE TO GASOLINE IS TOXICITY. SEVERAL COMMON CONSTITUENTS or GASOLINE HAVE BEEN LINKED TO VARIP'JS HEALTH PROBLEMS.
