Which is the final event in the six-event sequence?

• A. Stress
• B. Breach
• C. Harm
• D. Release

Answer: (C)

In this hazmat incident model, the events unfold in a chain from an initial trigger to the consequences. Stress on the system or container is the starting trigger. That stress can lead to a breach, where the container or system fails. Once breached, the hazardous material releases into the surroundings. People or the environment may then be exposed to the released substance, and the exposure can lead to adverse effects. The end result of this sequence is harm—the actual injury, illness, or damage caused by the exposure. So harm is the final event because it represents the culmination of the preceding steps. Stress is the starting point, breach comes next, release follows, exposure leads to harm, and safety efforts aim to interrupt this progression to prevent harm.
