What is the common characteristic of incidents described in the material?

• A. Potential loss of containment
• B. Environmental contamination
• C. Fire hazard
• D. Explosion risk

Answer: (A)

The key idea is that these incidents share the possibility that hazardous material could escape from its containment. In process safety, loss of containment means a release could occur if containment fails, even if a release hasn’t happened yet. So the material describes events where the concern is the potential for a release, not necessarily the actual result.

Environmental contamination, fire, or explosion are possible outcomes that can follow a release, but they aren’t present in every incident. The overarching, common feature across the described incidents is the risk of containment failure leading to a release.
