Definition - What does Primary Containment mean?
A primary containment is a device or container that is in direct contact with a hazardous material and is designed to limit the effects of harmful byproducts by reducing the risks of environmental and human contamination. It provides protection for personnel and the environment. This equipment is important for hazardous material handling processes.
Corrosionpedia explains Primary Containment
Accidents such as spills and chemical leaching can occur when dealing with chemicals and harmful materials. This loss of primary containment (LOPC) may lead to personnel injuries and water contamination. Therefore, linings are used in tanks and containers to prevent the leaching of harmful materials and in laboratories where hazardous materials are being handled. HEPA (high efficiency particulate arrestance) filters are used in primary containments when microbial agents exists as aerosols.
Primary containments are tested and inspected by health agencies before they are certified for use.
Examples of primary containments include:
- Biological safety cabinets
- Clean benchs
