• Toxic o VOCs Exposure Route: (Petroleum/Fuel-related Hydrocarbons) • Inhalation -Yes • Ingestion -No • Absorption -No Anticipated Acute Physiologic Response Pertinent Physical Properties: Volatile Qualified Exposure Risk: Moderate Primary "Control": • Dust Suppression (Water application) Work upwind Gasoline Lightheadedness Hazard: Gasoline is a complex blend of petroleum hydrocarbons primarily composed of paraffins, naphthalenes, aromatic and olefins. It is a colorless to red liquid with a petroleum odor that can be detected at extremely low concentrations. It is a flammable liquid with a high volatility and its vapors are heavier than air. Under conditions where exposure occurs, eye, nose, and throat irritation, headache, nausea, drowsiness, and dizziness/intoxication may possibly occur. Gasoline contains benzene, toluene, ethyl benzene and xylenes (BTEX) which are toxic or carcinogenic. A hazard assessment of these compounds follows this gasoline assessment. When certain proporti ons of a combustible vapor are mixed with air and a source of ignition is present, an explosion can also occur. The range of concentrations within which this will occur with gasoline is 1.3 percent to 8 percent. Therefore, under normal conditions, the lowest percentage of the material in the air in which an explosion will occur is the lower explosive limit (LEL) or 1.3 percent and the highest percentage of the material in the air is which an explosion will occur is the upper explosive limit (UEL) or 8 percent. Gasoline has a flash point of 45oC or 49oF. Controls : In open work areas, ventilati on is usually adequate to minimize prolonged breathing of high gasoline vapor concentrations. Extreme caution must be taken to prevent sources of ignition from coming into contact with COSTERA WA51'E &ENVIRONMENTAL, INC. 20 MAY 412021
