4? Compliance? with? Regulations? and? Safety? Considerations 4.1? Compliance? with? Regulations? and? Standards 4.1.1 The closure in place, removal, storage, and of-site disposal of UST systems that have contained fammable or combustible fuids shall be accomplished in accordance with federal, state, and local requirements, this recommended practice, and accepted safety standards. 4.1.2 Before initiating work, the authority having jurisdiction (AHJ) should be notifed and consulted concerning applicable regulatory and permit requirements. 4.1.3 All applicable permits shall be obtained prior to beginning any work. Certifed or licensed contractors may be required in some states. Consult the AHJ for contractor requirements. Contractors, subcontractors, and their employees responsible for tank closure in place or removal shall be familiar with the following: a) all applicable safety rules and regulations, including OSHA’s Occupational Safety and Health Standards (Title 29 CFR Part 1910); b) the use of equipment and procedures for testing and vapor-freeing tanks; c) the handling and disposal of the types of wastes likely to be encountered; and d) the applicable sections of the publications referenced in Section 2. 4.2 Special Precautions During UST removal or closure in place, workers may be exposed to petroleum hydrocarbon liquids, vapors, or wastes. The precautions in 4.2.1 and 4.2.2 should be observed by all individuals engaged in the procedures discussed in this recommended practice.
4.2.1? Toxicity? Considerations? for? Petroleum? Substances 4.2.1.1 General All personnel involved in the work shall be aware of appropriate health and safety precautions. When high concentrations of petroleum hydrocarbon vapors are inhaled, symptoms of intoxication may result. These symptoms, ranging from dizziness to excitement or unconsciousness, are similar to those produced by alcohol or anesthetic gases. If such efects occur, the individual shall be removed to fresh air. For minor efects of exposure, breathing fresh air or oxygen results in rapid recovery. If breathing has stopped, artifcial respiration shall be applied promptly. Medical attention shall be obtained as soon as possible. Paragraphs 4.2.1.2 and 4.2.1.3 contain special toxicity considerations for benzene and tetraethyl lead, which may be present in petroleum products or wastes found in or around USTs. Care shall be exercised to minimize exposure to these substances when they are present during the handling of used underground petroleum storage tanks. WARNING? — Tests have shown that prolonged or repeated exposure to some petroleum substances in liquid or vapor form may cause serious illness, including cancer, in laboratory animals. Although the signifcance of these test results to human health is not fully understood, exposure to petroleum substances should be minimized. The following health precautions are suggested. a) Avoid contact with skin and inhalation of vapors.
b) Keep petroleum liquids away from eyes, skin, and mouth; they can be harmful or fatal if inhaled, absorbed through the skin, or ingested. c) Use soap and water or waterless hand cleaner to remove any petroleum product that contacts skin. Do not use gasoline or similar solvents to remove oil and grease from skin. d) Promptly wash petroleum-soaked clothes and avoid using soaked leather goods, taking care not to expose to ignition sources. Properly dispose of rags. e) Keep work areas clean and well ventilated. f) Clean up spills promptly. 4.2.1.2 Benzene High occupational exposures to benzene have been associated with various human blood disorders, including an increased risk of leukemia. Very high levels have also been known to afect the central nervous system. Benzene administered by mouth has induced cancer in laboratory animals in long-term tests. Benzene is rapidly absorbed through the skin. The Occupational Safety and Health Administration (OSHA) imposes limits on occupational exposure and requirements concerning the communication of hazards to workers. See 29 CFR Part 1919.1000 (Table A-2), Part 1910.1028, and Part 1910.1200. All exposure limit values should be based on the most current and stringent published industry and regulatory values.
