    • AUse physical force immediately
    • BDe-escalation first, then physical intervention only if necessary
    • CIgnore them
    • DAlways fight back

    Answer: De-escalation through calm communication is always the first approach. Physical intervention should only be considered as a last resort when de-escalation fails and there is genuine danger.

    • AYour physical size
    • BThe threat level, the person's behaviour, and available alternatives
    • CYour experience level
