Field <br />personnel are strictly forbidden to enter any confined <br />spaces, for any reason, as a safety mandate of this SEP. <br />Therefore, the SHP does not currently address confined space <br />entry hazards and/or safety procedures. The SHP shall be <br />revised, reviewed, and approved prior to any confined apace <br />entry work. should this operation become necessary. <br />8.3.7 HOT WORK• <br />Hot work may be defined as any operation which may <br />potentially create a source of ignition. This operation is <br />extremely dangerous when conducted anywhere that A flammable <br />and/or explosive atmosphere (or fire hazard) may be present. <br />because the tanks and pipelines to be removed and scrapped <br />are expected to contain at least some residues (if not <br />measurable Quantities) of gasoline (i.e., flammable or <br />combustible. depending on the substance). sources of <br />ignition shall be eliminated during all operations that say <br />Interact with tank atmosphere. <br />For tank removal operations, all tanks shall be inerted <br />using dry ice at 30 lbs. per 1,000 gallons. tank <br />atmospheres shall be checked using a properly calibrated <br />combustible gas meter for percent oxygen (X Ox) prior to <br />removal from the ground. AND prior to opening and scrapping. <br />Representative samples shall be taken from various <br />locations/levels within each tank to ensure that the <br />environment is consistant. Prior to lifting and cutting. <br />atank atmospheres must be less than 10 percent LEL (<ION <br />LEL) and less than 12 percent oxygen (<12% 0w). <br />
