Why LUNAR matters

NIOSH firefighter fatality reports repeatedly cite trapped firefighters either failing to declare a Mayday at all or failing to communicate clearly when they did. The LUNAR framework — Location, Unit, Name, Air remaining or Assignment, Resources needed — gives a structured 15-second transmission that the IC can act on without follow-up.

Why practice in non-emergency time

Under stress, motor function and verbal recall degrade. Radio mic in hand, low air, hostile environment — this is the wrong time to invent a Mayday script. The training tool generates random drill scenarios so the radio-call habit is built before it matters.

Drill share link

Generate a scenario, copy the share link, and pass it around the kitchen table for the next shift drill. Big-screen mode displays the LUNAR template large enough for projection.

FAQ

Location (where you are — building, floor, room), Unit (your apparatus / company), Name (your name and rank), Air or Assignment (air remaining and what you were doing), Resources (what you need — RIT, additional crews, specific tools, or extraction support).

Mayday criteria typically include: lost or disoriented, low or no air, trapped, fallen through a floor, partner missing, structural collapse, or any condition that prevents self-rescue. NIOSH studies show firefighters often delay or fail to declare — the rule is 'when in doubt, Mayday.' It is easier to cancel than to wait.

Mayday is firefighter in distress (life-threatening, self or partner). Emergency Traffic is a non-life-safety urgent message (fire condition change, structural concern, evacuation order) that needs immediate radio priority. Both clear the channel; both are received and acknowledged by the IC.
