Use the word __________ only when expeditious compliance is required to avoid an imminent situation.

• A. Immediately
• B. Urgently
• C. Promptly
• D. ASAP

Answer: (A)

Timing of response in safety instructions is about requiring action without delay to prevent an imminent situation. Immediately means right now, without any pause, signaling that compliance must occur at once to avert danger. The other words carry urgency but allow some delay: urgently suggests priority but not instant action; promptly means without unnecessary delay but can still include a small pause; ASAP indicates as soon as possible, which is flexible and context-dependent rather than strictly no-delay. In situations where waiting could lead to harm, using immediately removes ambiguity about timing and ensures the action is taken right away. For example, telling someone to evacuate immediately conveys that there is no time to wait, whereas the other terms could be interpreted as acceptable with a brief delay.
