In the world of information technology, some professions are particularly perilous. Whether you’re risking psychological stress or your very life, these fields aren’t for the faint of heart. Some people in these roles thrive on adrenaline, climbing thousands of feet to fix communications towers. Others risk only emotional damage, getting paid to consume disturbing Internet content.

Workplace deaths in the United States have dropped in recent years, along with the employment rate. In the developing world, though, certain countries have a long way to go before some technology-related working conditions can be called humane.

1. Internet Content Moderation

Think of the most disgusting things you've stumbled across online. Now imagine viewing the stuff that nightmares are made of--hate crimes, torture, child abuse--in living color, from 9 to 5 every day. That's the work of Internet content moderators, who get paid to filter out that kind of material so you don't have to see it pop up on a social network or photo-sharing site. Demand for the work is growing, especially as more Web-based services enable users to post pictures instantly from their mobile devices.

"Obviously it's not the job for everyone," says Stacey Springer, vice president of operations at Caleris. The West Des Moines, Iowa, company's 55 content moderation employees scan up to 7 million images every day for some 80 different clients. "Some people might take it personally if they have a child and see images of children that might be sensitive to them, or if they see animal cruelty."

Caleris content reviewers receive free counseling as well as benefits including health insurance, but for some the psychological scars don't heal easily.

2. Electronics Assembly

Safety nets around the dorms of an electronics factory in Shenzen, China, are a grim reminder that ten employees have jumped to their death there since January. A 25-year-old employee who later committed suicide reportedly had been beaten at the Hon Hai plant after losing a prototype iPhone 4 last year.

Recall the frenzy, hoopla, and lines around the block at the launch of Apple's latest smartphone, and you can imagine the deadline pressure for the people assembling it. Foxconn, which makes iPhones, iPads, and other electronics from Apple, Dell, and HP, has been accused of fostering "sweatshop" conditions. However complex the chain of events leading to suicide may be, human-rights groups have criticized Foxconn and other manufacturers for creating an unbearable, pressure-cooker environment for workers, mostly young migrants from rural areas.

In light of the suicides, the company has raised wages, promised psychological testing for employees, and tried to boost morale with rallies. Foxconn plans to increase its workforce of more than 900,000 to 1.3 million in the next year.

Psychological pressure isn't the only rough condition reported in electronics factories, though. Labor and human-rights organizations also charge that workers testing microchips and assembling LCDs for Samsung were exposed to radiation that caused cancer.

3. Fixing Undersea Internet Cables

Cables that span the oceans keep people connected online across continents. Contrary to popular belief, it's hard connections such as these--not satellites in space--that provide more than 99 percent of the world's Internet connectivity. Someone has to lay and fix those cables when an undersea earthquake or errant anchor cuts off the data flow.

About 70 vessels around the world are tasked with fiber-optics installation and repairs. Some are on call around the clock. Each has a crew of about 50 people, including cable-installation engineers and controllers of remote-operated vehicles, who spend weeks or months at sea.

Robots rather than human divers lay and bury cables in the seabed as deep as 16,000 feet below the water's surface, but it takes the human hands on deck to haul in, repair, and drop heavy cables. Though they wear rubber gloves, in a worst-case scenario a cable operating with 10,000 volts could become energized. And looking straight into the lasers of a sliced cable can burn out your retinas in a matter of seconds.

As with fishing--perhaps the deadliest profession--this job carries the risk of encountering "acts of God" on the sea. Members of the crew are also prone to slips, trips, and falls on wet decks.

Elaborate layers of safeguards on the vessels reflect the dangerous nature of the work, says John Davies, managing director for Global Marine Systems, the largest company that handles submarine Internet cables.

4. Communications-Tower Climbing

Close to 11,000 people install and fix the communications towers that keep our mobile calls connected. In 2006, 18 of them died on the job.The head of the Occupational Safety and Health Administration in 2008 called cell-phone-tower climbing the most dangerous work in America.

"Clearly it was the most dangerous job if you looked at a niche industry," says Craig Lekutis, president of the news portal

Communications towers can reach 2000 feet high.

The industry has made improvements, but any work at extreme heights involves the risk of a fall. Fatalities tend to happen when workers don't use the right safety gear, or when they disconnect just for a moment. When a person is positioned 30 to 2000 feet in the air, such shortcuts can make routine tasks--such as testing an antenna--deadly. Accidents can happen even when the employee takes precautions; a tower can weaken at its base and fall, for instance, or a lanyard can break from a safety harness.

Amid a construction boom to make way for 3G and 4G wireless networks, Lekutis estimates, there are a quarter of a million communications towers--and rising.
