John Sevcik is an exceptionally meticulous man. Whether tending his yard or repairing a porch railing, he’ll check, then recheck every detail — once, twice, maybe even three times. No, he’s not obsessive-compulsive. It’s that as an electrician, he likes to play it 100 percent safe — all the time.
“You have to have a healthy respect for electricity,” says Sevcik, who has worked as an electrician around Cedar Rapids, Iowa, for almost 35 years. “You can’t fear it, because you have to work with it. But you must respect it. You have to constantly remember that you’re working with a very powerful, deadly force. One wrong move or stupid mistake and you put your life on the line, as well as the lives of your co-workers.”
Currently an industrial electrician for a paper-manufacturing plant, Sevcik is accustomed to working with very high voltages of electricity that power heavy machinery. But even low voltages can be life-threatening, as he knows from hard experience: Sevcik has almost been electrocuted twice.
On one occasion, he had climbed a ladder to thread wire through a conduit. Under normal circumstances power to the line would have been cut, but not this time. An electrical current surged through one hand, traveled up an arm, crossed his chest, then descended the opposite arm to exit by way of his other hand. Trapped and unable to free himself, both hands locked onto the power line, Sevcik was frozen on the ladder, the muscles in his upper body rigid and screaming with tension. Fortunately, he had the presence of mind to jump clear of the ladder and break the deadly connection. The relatively low 115-voltage line could have easily killed him had the current passed through his heart.
Welcome to Voltage Central. Nearly half of the approximately 175 deaths caused each year in the electrical trades occur in construction, with electricians accounting for about 7 percent of total deaths in the building trades, according to the Bureau of Labor Statistics. A glance through federal safety reports on electricians tells the story, with one fatality report after another on the sudden deaths of electricians, often in their 20s and 30s, electrocuted while trying to fix wiring, appliances, light fixtures, air conditioning units, and underground power lines.
All electricians — whether they work in industry, for commercial businesses, or in residential settings — are exposed constantly to the danger of electricity. Interestingly, it’s not the most common cause of injuries. Like construction workers, electricians spend a good portion of their time up in the air — perched on ladders, adjusting overhead lines, scrambling over roofs, and crammed into ceiling crawlspaces — so falls are common. Federal reports note that one young electrician’s helper, for example, died recently when he stepped on a skylight that broke and sent him crashing to the floor below.
“Electrocution is actually pretty far down on the list of the most common injuries we see,” says Bill Hanes, business manager for International Brotherhood of Electrical Workers (IBEW) Local 405. “Believe it or not, falls are our number one source of death and injury. This even surprises me.”
Flash burns from electrical explosions are another cause of injury. “Every time an improper connection is made, an explosion can occur and small particles of metal or copper wire shoot off in all directions, like shrapnel,” Hanes says.
Sevcik knows well that even a momentary distraction can result in a significant burn. As he was preparing a large alligator clip to hook up a test meter on a piece of equipment, he turned away for a split second. Aiming to attach the ground connection, he instead jerked his arm slightly, causing the clip to hit a 13,000-volt energized wire. Luckily, the rubber boot insulating the alligator clip protected him from flying shrapnel, but the explosive force of the accident burned his arm badly enough to require a trip to the emergency room.
Lurking in the walls
Environmental hazards such as lead solder abound at every job site. Electricians have made strides, however, in reducing some of the most deadly environmental hazards, such as exposure to cancer-causing asbestos. Sevcik can recall a time when it was common to saw asbestos piping without wearing protective equipment. Although today electricians exposed to asbestos that will be disturbed use respirators, those exposed to asbestos in the past needed to have routine check-ups to make sure their lungs were clear.
“A few years ago, asbestos probably would have been the number one health care concern for electricians, contributing to lung diseases and cancers,” Bill Hanes says. “But now we know how to handle it properly. And with all of the removal efforts of the last decade, we don’t run into it very often anymore.”
Repetitive stress hazards
Aside from these obvious hazards, the trade takes its toll on the body in other ways. Many electricians routinely suffer from chronic ailments, including back strain, hand abrasions from constantly pulling heavy wires through conduit, and repetitive stress from doing the same motion hundreds and even thousands of times. Sevcik says he knows of at least one or two electricians a year who have surgery for carpal tunnel syndrome, a pinching of the median nerve in the wrist. Although he has suffered symptoms off and on over the years, he says the technical nature of his current job has brought the disease more or less under control.
An electrician’s apprenticeship program is long and arduous, because knowledge means safety. During the five years that apprentices spend in classroom instruction and on-the-job-training, they’re never left alone on the job site. A journeyman electrician takes full responsibility for an apprentice’s safety during training. As with any profession, companies vary in their professional ethics and safety standards. If you’re an electrician, consider associating only with unions, companies, and contractors that make worker safety a priority. Most good job sites maintain a full-time safety officer who conducts weekly meetings on everything from ladder safety to safety training and enactments of real-life incidents that can result in injury.
Tips for working safely with electricity
- Before you start working on electric equipment, make sure the power is turned off! This may seem obvious, but reports from the Electronic Library of Construction confirm that people responsible for installing or maintaining electrical equipment often fail to turn off the power source before beginning to work on it, with tragic results. If the power is on, you may get a short circuit with an arcing fault if a metal screwdriver, wrench, fish tape, or other equipment touches grounded metal or a conductor.
- Turn off the switch or circuit breaker before working on it. If the cover is open when a switching operation occurs, you can be severely burned from the hot gases and tiny metal particles that occur during the flash.
- Remember that your body conducts electrical current, and that an electric shock of 120 volts can often be just as deadly as 600 or more volts.
- Use “lock out/tag out” procedures to protect yourself when working on systems being shut down.
- Wear protective equipment. The Occupational Safety and Health Administration requires that safety gear, including steel-toed work shoes, ear protection, safety glasses and a hard hat, be worn on all job sites. You should also have access to high voltage gloves, sticks and testers, with rubber on the inside and leather on the outside, to insulate yourself from electric current.
- Get your equipment inspected periodically. An electrician should know at a glance the month each piece of equipment was last inspected and approved.
- See a doctor at the first signs of repetitive stress injury. Chronic pain or heaviness in your arms may indicate tendinitis, and numbness and tingling in your hands, especially at night, is a sign of carpal tunnel syndrome.
- Avoid short cuts when working with wiring, such as removing the ground from a plug, running extension cords in damp or wet areas, and splicing flexible cords together.
- Don’t get complacent around electricity. The National Institute for Occupational Safety and Health (NIOSH) calls this the “I’ve never had a problem before” syndrome. Since most electricians who receive safety training work on 120/140-volt systems, NIOSH says, “a few shocks, sparks, or burned wires may not deter them… Transferring this 120V experience to 480V and above can be a fatal error.”
Meanwhile, electricians who live to tell of their close encounters with electricity generally vow to be more careful in the future. John Sevcik was fortunate to sustain no lasting injuries from his two electrocutions, but they did serve as a powerful wake-up call. Still, despite all the potential hazards and dangers of an electrician’s trade, Sevcik says he wouldn’t want to do anything else. “I’ve seen a lot of people get hurt, and I’ve been hurt myself,” he says. “But I also see the great positive powers of electricity. I’m in awe of how much it improves the quality of our lives.”
