5.1 This practice is intended for use in collecting samples of consolidated or compacted materials from drums or similar containers, but only in compliance with a suitable work plan prepared according to Practice D5283 and Guide D4687. If the plan so provides, samples may be collected from drums not intended to be opened and from drums that are unstable, ruptured or otherwise compromised. Special handling procedures (for example, remote drum opening, overpressurized drum opening, drum deheading, etc.) are described in Drum Handling Practices at Hazardous Waste Sites.

1.1 This practice covers typical equipment and methods for collecting samples of consolidated solids in drums or similar containers. These methods are adapted specifically for sampling drums having a volume of 110 U.S. gal (416 L) or less. These methods are applicable to hazardous material, product, or waste. Specific sample collection and handling requirements should be described in the site-specific work plan.
