Which of the following is NOT a type of hazardous materials incident?

A controlled release is a deliberate act where hazardous materials are released in a manner that is managed and monitored, often with the goal of minimizing risk to health and the environment. It is usually done under specific conditions and for certain purposes, such as testing or demonstration.

In contrast, actual releases, potential releases, and threats represent situations where hazardous materials are either currently being released, could be released, or where there is a risk of a release occurring due to various factors. These scenarios typically reflect unintended or uncontrolled occurrences of hazardous material exposure. Understanding these different classifications helps in emergency response planning and risk mitigation for hazardous materials incidents.
