Llama Fire in HWMD: a WUI Success Story
|
On February 24, 2008, a fire in a burn barrel on private land started a wildfire that spread onto the neighboring,
federally owned Maga Ta‑Hohpi WPA.
Wolsey VFD responded to the wildfire.
The head of the fire burned up to, and was stopped by, the black line put in during HWMD's Blackline Trials.
This freed the forces on scene to contol the flanks of the fire.

Burning Blacklines on a Game Farm Near Sterkfontein, South Africa
Blacklining was done in windy conditions using a crew of four: a tractor driver, a high-pressure handgun operator directly behind the
Blackline Burner, a spotter with a backpack sprayer 200 yards behind the Blackline Burner, and a standby high-pressure handgun operator.
Vegetation was a dense mix of dry grass and
Seriphium plumosum (Bankrupt Bush)
