And then use giant machines to crush, pack, transport and store the waste. When you see them "run around and move dustbins", it's probably the easiest and safest part of their job. What you don't see is what happens at the landfill or incinerator plant, and this is a bigger part of the job than collecting waste from domestic customers.

They also run around and move garbage cans in the street where they can get hit by cars.

They also ride on the side of a truck, just holding onto a handrail and a step. If they lose their balance or grip that could be end badly too.

Also firefighters are rarely more than a few minutes from an ambulance.

I should look up the urban/wildland split on that death rate

They operate hydraulic machinery that has the ability to crush you in an instant and they're in and out of traffic on foot all day long.
