Attachments <br />(Tank Removal) <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 around 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 (CO2). 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 />0 <br />
