Risky job

Nowadays, the world is full of risky jobs. Some people get a risky job because they qualify for it. However, work as a broadcasting technician is very risky.   I have a reason that can shed light on my argument. One reason is that a technician for this antenna has to climb all the way from the bottom to the top. For example, I have seen yesterday in YouTube a man climbed a 1768 feet tower to fix a problem. In my opinion this job has high risk because the person might fall down. Another strong issue could be an emotional problem that a person faced the night before he went climbing. If he gets a call to go and fix a problem he might not say no the boss.  I means he will take a huge risk can that lead him to  hisdeath.
