 The death toll is believed to be the third worst for firefighters battling a wildfire 
 
 Firefighter fatalities have declined in recent years 
 
 The Arizona wildfire tragedy that has claimed the lives of 19 firefighters is the deadliest incident for firefighters since 9/11 and the third highest firefighter death toll on record for wildfires, the National Fire Protection Association said Monday. 
 
 The collapse of the World Trade Center's twin towers in 2011 killed 341 firefighters and two paramedics. 
 
 Among wildfires, the 1910 Devil's Broom wildfire in Silverton, Idaho, killed 86 firefighters; the 1933 Griffith Park blaze in Southern California killed 29, the association reported. 
 
 California has had three of the five most deadly wildfires for firefighters. Besides the Griffith Park fire, the Rattlesnake Fire in the Mendocino National Forest killed 15 firefighters in July 1953 and the Inaja Fire in the Cleveland National Forest killed 11 in November 1956. 
 
 In recent years, firefighter fatalities actually have been declining, the NFPA said. The group recently released its annual Firefighter Fatality Report that listed 64 firefighter on-duty deaths in 2012, the second lowest in 35 years. For the past four years, the annual total has been less than 100, dropping the annual average over the past 10 years to 88 deaths, the NFPA said.

– It's clear that yesterday was a brutal day for firefighters, with 19 killed in Arizona's Yarnell Hill Fire. But USA Today puts the tragedy in starker terms: It's the worst day our nation's firefighters have suffered since 9/11, and in terms of wildfires, it's the third deadliest day on record. It references data from the National Fire Protection Association, which adds the fatalities to its list of deadliest occurrences of all kinds: 340: Killed at World Trade Center on 9/11 86: Dead in Silverton, Idaho's Devil's Broom wildfire, 1910 29: Dead in California's Griffith Park fire, 1933 27: Killed in Texas City, Texas, ship explosion, 1947 21: Killed in a meat packing plant fire in Chicago, 1910 19: Those who died in the Yarnell blaze will tie with an 1882 fireworks plant tragedy in Chester, Pa., and a refinery blast in 1956 in Dumas, Texas Yesterday's toll could have been 20: The AP reports that one member of the hotshot crew survived after separating from the team to move its vehicle. The NFPA adds that the number of firefighters to perish each year has actually been dropping; the annual average for the last decade is 88, but last year's toll was a lower 64.
