D5743-21 – Standard Test Method Technical Guide
📐 Scope and Applicability
This practice covers typical equipment and methods for collecting samples of single or multilayered liquids, with or without solids, in drums or similar containers. It is specifically adapted for drums having a volume of 110 gallons (416 liters) or less. These methods are applicable to hazardous material, product, or waste. Specific sample collection and handling requirements should be described in a site-specific work plan.
Note: This standard uses inch-pound units as standard, with SI units provided for reference only. Always verify the applicability of regulatory limitations before sampling.
⚙️ Sampling Procedure and Equipment
The procedure begins with a thorough inspection of the drum and its contents. A clean sampling device is selected and slowly lowered into the liquid. After the material enters the device, it is removed from the drum and discharged into a sample container. The device is then either disposed of or cleaned and decontaminated following Practice D5088.
For drums that are unstable, ruptured, or compromised, special handling procedures such as remote drum opening or over-pressurized drum opening may be necessary. These methods are described in supplementary documents like the Drum Handling Practices at Hazardous Waste Sites.
📊 Key References and Safety
