Non -floating swing line Indicators show <br />the opposite. <br />2 <br />Cable: check for wear or fraying. <br />3 <br />Does the floating suction board indicator have <br />top and bottom position markings on the shell <br />with written labels? <br />4.0 <br />FIXED ROOF <br />4.1 <br />GENERAL <br />E <br />OK <br />NA <br />Comments: <br />1 <br />Is the roof free of debris? <br />o r- a a <br />2 <br />Record the roof type, roof slope, and roof -to - <br />shell connection dimensions. <br />3 <br />For aluminum dome roofs, record the <br />manufacturer and serial number. <br />4 <br />Record roof thickness measurements (steel <br />roofs). Take at least 10 thickness <br />measurements at a maximum spacing of 10 ft <br />along two perpendicular lines. If any thickness <br />Is less than 0.09 in., measure 3 additional <br />thicknesses In a 100 int area around that <br />location. <br />4.2 <br />ROOF <br />CORROSION <br />I E <br />I OK <br />NA <br />I Comments: <br />Revision Date: Oct2013 Page 4 of 9 <br />-IZALTH <br />T <br />
