What is the primary receptacle?

The primary receptacle is defined as the container that directly holds the hazardous material or specimen. This is important because it is the first line of defense against leaks or spills. The primary receptacle is responsible for maintaining the integrity of the contents and ensuring safe transport. It is typically designed to minimize the risk of breakage or leakage, and it must be properly labeled to identify the contents and any hazards associated with them.

In the context of transporting dangerous goods, understanding the role of the primary receptacle is crucial for ensuring compliance with safety regulations and for the protection of both handlers and the environment. Proper containment starts with the primary receptacle, which is followed by secondary and outer packaging for additional safety, but the primary receptacle is the one that directly contacts the hazardous material.
