Safety note: Mayday protocols vary by department. Use this guide as an education and rehearsal framework—not as a replacement for policy.
What LUNAR Means (and Why It Works)
LUNAR is a memory framework that forces the message to include the minimum details command and RIC need fast. Many departments use a version like:
- L – Location: where you are (best possible description you can give).
- U – Unit: your company/apparatus identifier.
- N – Name: who is in trouble (or “one firefighter”).
- A – Air / Assignment: air status and what you were doing.
- R – Resources / Rescue needs: what you need now (e.g., line, ladder, disentanglement, RIC contact).
Rule: Short and structured beats long and emotional. A clear location + needs often matters more than extra story.
When to Call a Mayday (Training Triggers)
Departments vary, but training should include common trigger conditions so members act early:
- Lost / disoriented
- Trapped / entangled
- Fall through floor / collapse involvement
- Low air or emergency breathing
- Injured and can’t self-rescue
