In going through some papers today I rediscovered “Murphy’s Fire Behavior Rules” that govern wildfire suppression. I have no idea who created them. It’s possible that Rick Gale handed them out during a session in S-520, Advanced Incident Management, but I don’t think he was the author.
Murphy’s Fire Behavior Rules
- Winds will remain constant until your backfire is lit.
- Upon reaching the far side of the fire, all batteries cease to function.
- The last hard freeze of winter occurs the day after you fill the pumper.
- Rain occurs only after a fire is finally controlled.
- The arrival time for backup coincides precisely with fire containment.
- A 3:1 gas/diesel mixture burns hotter than 3:1 diesel/gas. So does the person carrying the drip torch.
- You are always one lunch short.
- Leakproof bladder bags will. Self-priming pumps won’t.
- Burning out the wrong side of the line will prolong the time of containment.
- Critiques are sometimes painful.
You may have some suggestions for #11.
