Firefighting isn't that dangerous. Of course there are hazards, and about 100 firefighters die each year. But firefighting doesn't make the Department of Labor's 2002 list of the 10 most dangerous jobs in America. Loggers top that one, followed by commercial fishermen in the No. 2 spot, and general-aviation commercial pilots (crop dusters and the like) at No. 3. Firefighting trails truck-driving (No. 10) in its risks. Pizza delivery drivers (No. 5) have more dangerous jobs than firefighters, statistically speaking. And fatalities, when they occur in firefighting, often are due to heart attacks and other lack-of-fitness problems, not fire. In those cases where firefighters die in a blaze, it's almost always because of some unbelievable screw-up in the command chain. It's been well-documented, for instance, that lousy communication was a huge reason why so many firefighters still were in the burning World Trade Center when it imploded, and well after city police and port authority police had been warned by their own commanders of an imminent collapse and cleared out.
