We have a couple of questions showing that in dry times a flare can start forest fires.
- Is there a safer way to use a flare in a wooded area?
- What is the risk of starting a forest or wildland fire with a flare gun?
Most flares will start easily when wet and even burn underwater. So would seem a tempting fire starting tool.
I am wondering about in wet times, if a flare would be effective for starting fires. Flares burn pretty hot 1,600 °C (2,900 °F) and I suspect that might actually make it more difficult to light a fire with wet wood/kindling.
We have some related questions, but they don't address flares.
