Which 10-code should be used to check if there are available units to respond?

• A. 10-40 Advise if Available
• B. 10-32 Answer Units Needed
• C. 10-36 Correct Time
• D. 10-45 Death

Answer: (A)

The key idea here is checking whether any units are free to respond before you assign a call. The code that asks for a status on unit availability is the one that directly serves this purpose: it prompts the dispatcher or units to report if there are any available to take the assignment. This keeps operations efficient and avoids sending calls to units that are tied up. The other codes aren’t about confirming who is free. One signals that you need additional units to respond, rather than simply asking who is available. Another is used for confirming the current time, which isn’t related to resource status. The last one is for reporting a fatality, not for coordinating responses.
