The following precautions will <br />be observed by all individuals engaged in the tank removal activity. <br />2.1.1 Toxicity considerations, Petroleum Substances: <br />All individuals should be aware of appropriate health precautions. When high <br />concentrations of petroleum hydrocarbon vapors are inhaled, symptoms of <br />intoxication may result. These symptoms range from simple dizziness to <br />unconsciousness. Care will be exercised to minimize exposure to these <br />substances when they are present. Avoid skin contact with petroleum <br />substances whenever possible. Use soap and water to remove any petroleum <br />product that contacts skin. <br />2.1.2 Flammability and Combustibility Consideration: <br />Flammable and combustible vapors are likely to be present in the work area. <br />Precautions will be taken to eliminate all potential sources of ignition, to <br />prevent the discharge of static electricity during venting, and to prevent the <br />accumulation of vapors. <br />2.1.3 Physical Considerations: <br />During the excavation some physical hazards can be present, in the form of <br />large holes, exposed piping, debris piles, and excavation equipment. All <br />workers will be aware of these hazards and take all necessary actions to <br />eliminate accidents, when left unattended the excavated area will be <br />appropriately marked and barricaded at all times. <br />
