I don't think there is a "most dangerous job".

In fact, you could even say Office Job is just as dangerous as any other. A typical office worker will be spending entire days and nights working the same monotonous cycle, paying years off his life just to make some money, and if they stick with it then as they grow older, they feel less and less compelled to change jobs. And then when they do get urges to change, they think: "but who will want to hire me, I spent the last decade or so grinding out this one job. I don't have much other experience". And even if that thought is actually untrue, the office worker doesn't know that.

You'd expect them to have some intelligence and go out and find a new opportunity, but then you hear all these horror stories about people slaving away at 9-5s, and you realise how many people can't or don't get up and leave. Then you find out that 8/10 Americans are slaving away at a desk all day.

By age 70, you've retired with a pretty comfortable sum of money, but you've got 10 years? 15 if you're lucky. So go have fun and enjoy yourself, but then realise eventually that, every year that passes, your body is deteriorating more and more rapidly from age. Being old and fragile sucks pretty bad huh? And that's assuming a lifetime of sitting down for 9-10 hours every day hasn't caused obesity, arthritis, diabetes, cancer and a wide variety of heart diseases.

Now granted, everybody that commented before this are not wrong. There are dozens of professions that are more inherently dangerous to a person's immediate health and well being.

Construction worker? They risk falls to the deaths, electric shocks and the frames of the building they are working on collapsing on them.
Policeman or fireman? One risks being shot or stabbed on the job, while the other risks being burned alive to death.
Journalist? Many journalists go to places most people would rather not go to, places plagued with famine, poverty and terrorism.

And countless more. And I'm not ignorant or naive enough to think working in an office for 9 hours a day sitting in a comfortable chair typing away at a laptop is more 'dangerous' than say, getting called up to a hostage scene with a dozen other police officers, and trying to stay calm because inside the building, innocent people -- people with families and lives and personalities and consciousness, could have their lives ended if you or your fellow officers make a single miscalculation in how to proceed. And how you or a co officer could be shot and put in the ER any moment.

HOWEVER.... Like I said earlier, I don't believe there is a most dangerous job. However, working as a police officer or fireman or journalist or construction worker and making an impact on the society and city you live in, versus working an office job where you're just helping a rich person get richer... One of these will likely leave you feeling lost and regretful by the time you retire, and the other will leave you smiling and showing pictures to your grand kids of how cool you were back in the day. And that is where the office job becomes just as dangerous as any other profession. Not to yourself at the present time, but to you 50 years down the line. The only reason why it isn't MORE dangerous, is because while most other professions will leave you satisfied and happy and excited to tell stories 50 years down the line, those professions may also get you killed way before that time comes.
