The selection of <br /> sampling equipment and procedures should be based on site-specific conditions such as the <br /> type and volume of material to be sampled. The selected sampling equipment should be <br /> constructed of inert materials that will not react with the material being sampled. The <br /> following equipment may be required to sample bulk materials: <br /> • Trier <br /> • Scoop <br /> • Trowel <br /> • Grain thief <br /> • Spoons or spatulas <br /> • OVA/FID or PID <br /> • Decontamination materials <br /> • Sample containers and labels <br /> • Chain-of-custody and shipping materials <br /> • Field logbook <br /> • Stainless-steel or Teflon®tray <br /> Additional resources for sampling bulk materials are discussed in The Sampling of Bulk <br /> Materials by R. Smith and G. V. James of the Royal Society of Chemistry, London (1981). <br /> Although this book does not deal specifically with hazardous waste sampling, the concepts <br /> discussed are applicable, especially those regarding establishment of sampling scheme. <br /> 2.0 PROCEDURES <br /> Bulk materials are usually contained in bags, drums, or hoppers, although large amounts of <br /> material may be piled on the ground, either deliberately or as the result of a spill. <br /> Material surfaces exposed to the atmosphere may undergo chemical alteration or <br /> degradation and should be removed before initiating sample collection. Because the process <br /> conditions that produced the bulk material may have varied over time, a series of samples <br /> should be collected and composited into one sample to represent the material.
