Which statement about handheld flares is true?

• A. They typically burn for 30-60 seconds
• B. They burn for several minutes
• C. They do not require caution
• D. They are used underwater

Answer: (A)

Handheld distress flares are signaling devices whose usefulness depends on how long they burn. The standard burn time is about 30 to 60 seconds, which is long enough to be seen by rescuers over a distance but short enough to limit heat and fire risk. This short, visible interval is why the statement about 30–60 seconds is the true description of typical handheld flares.

They require caution because of the open flame and hot casing—so keep the flare away from your body and gear and use it in open water with others nearby. They do not burn for several minutes; that longer duration isn’t typical for handheld signals. They are not used underwater, since they need air to burn and to create a visible signal.
