Containment

"Containment" in the sampling of bulk materials refers to the application of specific methods and procedures to prevent the bulk material from being contaminated or released during sampling, transportation, and storage. It is of particular concern when the bulk material is hazardous or harmful to health or the environment.

Containment methods may include several strategies:

  1. Closed systems: Sampling is performed in a closed system to minimize exposure and contamination.
  2. Use of appropriate containers: Samples are collected in specialized containers designed to securely contain the bulk material and prevent any release.
  3. Controlled environments: Sampling can be conducted in a controlled environment, such as a glovebox, to minimize exposure and contamination.
  4. Special tools and equipment: Special tools and equipment may be used to make sampling safer and more effective.

Containment helps ensure the safety of personnel, preserve the quality of samples, and minimize the loss of bulk material during sampling and analysis. It is a critical aspect of quality control and compliance in many industries, including food processing, pharmaceuticals, mining, and chemical manufacturing.
