ACID stands for what four actions?

• A. Assess, Contain, Initiate, De-escalate
• B. Assess, Contain, Isolate, Debrief
• C. Assess, Contain, Isolate, De-escalate
• D. Assess, Calibrate, Isolate, De-escalate

Answer: (C)

ACID is a step-by-step safety response framework used to manage potentially escalating incidents. It starts with Assess, quickly gathering information about what’s happening, who’s involved, and what risks exist. Then Contain, establishing boundaries and actions to prevent the situation from worsening and to keep others safe. Next Isolate, separating individuals or hazards when necessary to reduce risk and prevent contact or interference. Finally De-escalate, using calm communication and nonthreatening actions to reduce tension and resolve the situation safely without force.

This sequence fits the standard protocol because it moves from understanding the danger, to controlling the environment, to separating threats, and finally to calming the situation. The other options change one term to another that doesn’t align with this established process—for example, Debrief occurs after an incident, not during the active response; Calibrate isn’t part of this safety framework; Initiate doesn’t capture the necessary step of separating individuals when needed.
