This can be a totally different incident from the Route Hearth that burned 454 acres a number of miles away alongside Interstate 5 September 11, 2021. It's possible you'll do not forget that hearth because the one the place 13 firefighters who have been turning into quickly entrapped have been crammed into two US Forest Service engines and rescued with solely moments to spare. There have been 23 our bodies within the two engines, with seating designed for 5 every. One other 11 firefighters not fairly as near the flames have been rescued by Los Angeles County engines.
The 4 QRF helicopters are all staffed for 24-hour protection and outfitted for evening flying. With most of their base funding provided by Southern California Edison they’re positioned in Orange, Los Angeles, and Ventura Counties. Two of the helicopters are CH-47 Chinooks, one is an S-61, and the fourth is an S-76 used for aerial supervision. The helicopters are dispatched as a unit together with a cell hearth retardant base and may drop water till the bottom is established. The truth that they’ll drop retardant 24 hours a day, when fastened wing plane can’t work the fireplace at evening, generally is a sport changer. In the course of the Route Hearth the cell retardant base didn’t need to journey, it was arrange at its base about 10 miles from the fireplace.
The task given to the QRF by Los Angeles County Hearth Division on the Route hearth was for it to cease the unfold to the north. The S-61 was tasked to carry a specific location on the fireplace, utilizing water from the adjoining Castaic Lake. It averaged of 696 gallons per drop.
The 2 Chinooks dropped averages of two,434 gallons of water per drop and 1,896 gallons of retardant per drop. The three suppression helicopters flew a mean of 9 hours every that afternoon and into the evening, dropping 223,000 gallons of water and 55,000 gallons of retardant. The S-76 was used for 17 hours. The whole price of the retardant and flight time for the 4 ships was $403,950.
The report compares the Route Hearth to the 1996 Marple Hearth which began in about the identical location on the identical time of the day and time of yr in comparable climate situations. By midnight the Marple Hearth had exceeded 10,000 acres and continued spreading for 2 or three days till it was stopped at 19,860 acres.
In distinction, the unfold of the Route Hearth was stopped at 8 a.m. on Day 2. The three helicopters dropped water and retardant a lot of the evening to carry it at a ridge on the north aspect, permitting hand crews and dozers to finish hearth line.
It is rather troublesome to check the suppression prices of two fires that occurred 26 years aside, however the authors of the QRF report estimated that the price of the Marple Hearth in right this moment’s {dollars} can be someplace between $70 million and $140 million. The price of the Route Hearth was $7 million to $8 million.
