1. Dangerous Jobs

2. No 1: Skyscraper window glass cleaner You need tremendous courage to be a skyscraper window glass cleaner. If you suffer from acrophobia, forget this job. Glass cleaners are suspended on a narrow sill a few hundred feet above street-level - not a task for the faint of heart.

3. No 2: Helicopter cable worker Helicopter cable workers are those surreal-looking workers who fix various cables and power lines from a helicopter. The special conductive clothing these linemen wear allows them to work on high-voltage transmission lines with their bare hands.

4. No 3: Alligator wrestler Wrestling an alligator is a dangerous but exciting activity. To win an alligator-wrestling competition, wrestlers must place their heads between the jaws of real alligators there for a set period of time, an activity with obvious dangers.

5. No 4: Lion tamer Taming lions sounds an interesting job, but it is actually very dangerous due to the obvious risks of toying with the powerful instinctive carnivores.

6. No 5: Mine worker Working in a mine is undoubtedly a tough job. This job requires working outdoors, usually underground, for long periods of time. Workers often suffer from lung diseases. There are also a lot of accidents in which miners are killed in mine collapses, blasts, fires or landslides.

7. No 6: Target girl A target girl is a female assistant in circus performances such as knife throwing or archery. The assistant stands in front of a target board or is strapped to a moving board while an impalement artist throws knives or shoots projectiles so as to hit the board but miss the assistant. The potential for injury or death is part of the visual thrill for the audience.

8. No 7: Lumberjack The slopes of the mountains on which most logging is done make lumberjack work quite dangerous. Carrying heavy equipment up steep terrain with a slope of 70-80 degrees often leads to accidents, especially in extreme weather. There is also a very real danger of being injured by a falling tree.

9. No 8: Fisherman Working in the fishing industry is one of the most dangerous jobs in the world. Fishermen have to work long hours every day, sometimes in darkness, without time for breaks. The heavy equipment used to catch fish is rife with potential for accidents. And though GPS technology helps to direct fishing boats, but in bad weather conditions and fatal accidents still happen.

10. No 9: Land mine remover De-mining, or mine clearance, is the process of removing land or sea mines from an area. Since manual mine clearance is much more effective than any automated method, human workers are still used to do the dangerous work of deactivating the world’s land mines.

11. No 10: Construction worker Many accidents happen at construction sites. Workers often do their jobs under giant steel beams or on the uneven surfaces high above the ground. The most common cause of death among construction workers is falling. Explosions, electric shocks, loud noises, high and low temperature, solvents, smoke, asbestos and incorrect lighting can also be dangerous to construction workers.
