3. e Select the appropriate sampling accessories based on the location to be sampled Common sampling accessories include rigid and collapsible wands floats and sintered filters Each is available in variety of lengths e Prior to drawing a sample through a pump wand or other accessory the entire sample train must be tested for leakage This should be accomplished by blocking the inlet at the point furthest from the instrument and ensuring a bump block alarm is obtained CAUTION Most refinery gases are heavier than air and settle or flow to the lowest level within a space At the same time some hazardous gasses are lighter than air Hydrogen and natural gas are both much lighter than air and will normally rise and diffuse into upper atmospheric levels They will be trapped in the top of the unvented spaces of vessels fireboxes roofs and platforms Make sure gas testing is performed at various elevations within every space to ensure proper characterization of the atmosphere e Place the probe inlet at the lowest level of the space being tested Continue to check each open manway or at various elevations in open spaces to obtain representative gas test results e Keep sampling probe inlet above flammable liquid or water levels Liquids drawn into the instrument will make it inoperative Also you want to measure the vapors not the liquid The use of a float accessory on the sample wand may be helpful Page 2 of 13 PAPER COPIE
