Attachments <br /> (Tank Removal) <br /> u'N <br /> -SITE WORK PLAN <br /> FOR TANK REMOVAL AND EXCAVATION <br /> Removal of Flammable Vapors and Removal of Tanks <br /> Removal of flammable vapors and removal of tanks will be performed <br /> in accordance with the requirements of Local Regulatory Agencies. <br /> The following are general guide lines. <br /> A review of available codes, standards, and recommended procedures <br /> produces the following consensus: <br /> A. All possible sources of ignition must be kept from <br /> impacting the tank or the area in which flammable vapors <br /> may reside during excavation or after removal. <br /> B. Drain and flush all piping into tank. Flammable or <br /> combustible free standing liquid production stock will be <br /> removed from the tank prior to removal. Avoid spilling <br /> product on the ground during disconnection of the tank <br /> from its associated lines. <br /> C. Vent lines should not be sealed and should be cut last. <br /> Keep all sources of ignition away from vent lines as well <br /> as tanks. <br /> D. Once all liquid has been removed from the tank, any tank <br /> with flammable vapors in excess of 10% of the LEL or 5% <br /> oxygen will be purged with dry ice (Cod . Thirty pounds <br /> of dry ice per 1, 000 gallons of tank capacity is added to <br /> render the tank inert. All piping except the vent pipe <br /> should be disconnected. <br /> Emergency Services <br /> The address and telephone number of the local hospital, ambulance <br /> and medical emergency room should be prominently posted. In <br /> addition, the telephone number of the fire department/rescue unit <br /> should be posted. <br /> General information regarding emergency services may be found on <br /> front page. <br />
