For tower professionals and those that work in the broadcast and wireless industries, safety is paramount.
While certain risks may exist on one job, another site may pose completely different hazards, so for any professional working on towers, masts and antennas, assessing hazards has to be done on a site-by-site basis.
The most obvious risk people working in the tower and antenna world face are the daily climbs.
When a climb looks easy, or it is getting late in the day, it can be tempting to take short cuts. Many antennas, especially those in the cell phone industry, are these days located on top of roofs and other structures, and these can pose less obvious hazards for anybody tasked with repair or maintenance. Despite the Environment Protection Agency’s 1989 Asbestos Ban and Phase Out Rule, asbestos could still be present on some older buildings.
In addition to the RF Awareness training mentioned earlier, LBA now offers comprehensive Outdoor Worker Awareness training with certificate, on-line. The Greater Victoria School Board has placed a moratorium on the installation of wireless systems until it hears from a committee studying the potential for health impacts. After her request, CTV forwarded information to Orcherton, who will ask her committee to review it before making recommendations to the board. In tests conducted at four Vancouver schools, children in schools with Wi-Fi installed were found to have about the same exposure to electromagnetic emissions produced by the devices as schools without Wi-Fi. After being shown the results of CTV’s investigation, confederation chair John Puddifoot said he would speak with his board. Karl Reardon, the Planetworks engineer who performed the tests for CTV News, said that the signals coming from the Wi-Fi units were too low to measure on most equipment.
The province’s two largest school districts, Vancouver and Surrey, are hoping to have Wi-Fi installed in all of their schools by the end of next year.
When connected to these potential dangers, keep your distance from the source, such as your WiFi router. With most of the career with the Royal British Navy and military intelligence, Barrie Trower dedicated much of his career in the study of the effect of microwave energy on the human body.
In another example, Trower says, “I was previously aware of reports concerning dead birds in and around communication bases. Laptops, tablets, and other handheld devices connected to the internet via WiFi, can either rest on a desktop or a child’s lap emitting Electromagnetic Radiation (EMR).
WiFi in our classrooms, by some, is considered as dangerous as military microwave weaponry. Radiation from cell phones and telephone towers can cause health problems such as brain tumors, cancer, infertility, memory loss, depression, sleep and behavior problems. A recent AOL-Pew Research Center Mobile Lifestyle Survey revealed that 52 percent of American adults surveyed keep their cell phone turned on all the time while 40 percent of those between the ages of 18 and 29 are saying that they are increasingly likely to drop their land line once and for all. With an estimated three billion cell phone users worldwide and most adults and teenagers owning a cell phone or smart phone, it seems a bit late to be asking the question: are cell phones safe? Nevertheless, the Environmental Working Group (EWG) has reported that many research groups around the world are working hard to find out if cell phones are actually safe to use. All cell phones and mobile devices emit radiation in order to send all those voice calls and text messages which so many people depend on each day. Cell phone radiation exposure is long-term, and its effects on the body, particularly the electrical organ, the brain, are compounded by numerous other simultaneous long-term exposures including continuous waves from radio and TV transmitter towers, cordless phone base stations, power lines, and wireless computing devices. A malignant brain tumor represents a life-ending diagnosis in the vast majority of those diagnosed. Despite the dismissal of the physicians concerns by industry groups and millions of cell phone users, Dr. According to the Russian National Committee on Non-Ionizing Radiation Protection, child cell phone users are likely to face health hazards such as disruption of memory, decline of attention, diminishing learning and cognitive abilities, increased irritability, sleep problems, increased sensitivity to stress, and increased epileptic readiness in the near future. Expected (possible) long term health risks of cell phone use by children include brain tumors, tumors of acoustical and vestibular nerves by the age of 25 to 30 years, Alzheimer’s disease, dementia, depressive syndrome, and other types of degeneration of the nervous structures of the brain by the age of 50 to 60. The Committee emphasizes the ultimate urgency to defend children’s health from the influence of the electromagnetic fields (EMF) of mobile communication devices in order to prevent negative consequences to the future generation’s health.
Enter a home with WiFi, and you are immediately exposed to an invisible, odorless and untouchable Radio Frequency (RF) Electromagnetic Field (EMF). Recently, the American Academy of Environmental Medicine (AAEM) released an article entitled Electromagnetic and Radio Frequency Field Effect on Human Health which says, “In the last five years with the advent of wireless devices, there has been a massive increase in Radio Frequency (RF) exposure from wireless devices as well as reports of hypersensitivity and diseases related to electromagnetic field and RF exposure.” In short, radiation from modern wireless devices is increasing at an exponential rate, and lets face it, not going away anytime soon. WiFi is an electronic communication which enables wireless connection between a computer to the internet. The American Academy of Environmental Medicine (AAEM) reports there needs to be more scientific studies that better document evidence of thermal bioeffects and non-thermal negative health effects of RF exposure. This report goes on to say that WiFi will degenerate the kidney, can cause neurological damage and has proven to be the source of Electromagnetic Field Hypersensitivity (EFH). Because of its convenience, it’s a good bet that WiFi technology will all around us for the foreseeable future. EMF Shields can also be attached to your watch, iPod,hand-held computer, hair dryer,and other small appliances. It is also great for detoxifying our physical and subtle bodies while strengthening the immune system and providing pain relief and defense against disease.

While RF safety awareness is an important aspect of any hazard assessment, all professionals need to be mindful of all the other possible risks attached to the job. That being said, certain risks tend to exist at nearly every site, and because workers in the profession face them on a daily basis, it can be all too easy to forget just how potent these hazards are. Whether its 50 feet or 500 feet the consequences of a fall can be the same, and every height has to be respected equally. However, the job is dangerous enough without adding unnecessary risks into the equation, so properly assessing each tower before you climb and following OSHA or local safety procedures is vital to prevent becoming an unfortunate addition to the statistics. Apart from the various trip hazards caused by rooftop furniture, such as air vents, a less visible and more sinister threat can be present, especially on older buildings. This is because, before the health risks and the associations with lung cancer was realized in the early 1980s, asbestos was used as insulation and fireproofing almost everywhere. Not only is it unpleasant working in the bitter cold, pouring rain, or baking sunshine, but also the weather can lead to accidents and injury. Rain can obviously make climbing surfaces slippery, while metal antennas in sub zero temperatures pose skin contact risk.
It is important to know the symptoms of these conditions, and appropriate first aid for them.
Several hours behind the wheel will often result in feelings of tiredness, so time should be taken when arriving on site to shrug off feelings of fatigue.
But after hearing about a CTV News investigation on wireless signal exposure, school board chair Peg Ocherton said she wants to know more. The levels inside schools were about 10 times lower than a student would feel outside in the playground or walking to school. Confederation of Parent Advisory Councils voted in May to ask each school district in the province to set aside at least one school at each education level without Wi-Fi, cordless phones or cell phones, in response to some parents’ beliefs that the waves can cause everything from headaches to cancer.
Radio Science lab, studies radio waves, and says the emissions from wireless devices carry millions of times less energy than cancer-causing rays like UV from the sun. As far as any physical effects, they’re too weak to have almost any physical effect,” he said. To add to the confusion, over the past year or so, we are learning that WiFi transmitters emit Electromagnetic Radiation (EMR) similar to the microwave radiations used in the design of microwave weaponry. When using your laptop computer, iPad, tablet or other handheld device in your lap, be sure to use a laptop radiation shield.
He recently came out of retirement to share his experiences about WiFi in part, because he strongly understands that microwave radiation and WiFi radiation are very similar.
On examination these birds were found to be cooked.” He was referring to powerful microwave communications having the capacity to oscillate cells sufficiently as to cook the birds alive. Elsewhere within a building, there are access points and routers, also transmitting Electromagnetic Radiation (EMR). Trower believes all exposure is dangerous, but sometimes you may find it important to be connected to the internet via a WiFi connection. At the very least, we should be aware of the potential dangers and find ways to avoid them. Some (not all) studies of frequent cell-phone users suggest cell phone radiation may increase risks for cancer and children’s behavior problems. Since many cancers take more than a decade to develop and be detected, often well after it is too late, Dr.
According to a 2008 observational study by the Reproductive Research Center, use of cell phones has been shown to decrease the semen quality in men by decreasing the sperm count, motility, viability, and normal morphology.
Go into a school, office building or a coffee shop and you are exposed to even more radiation from multiple WiFi routers and repeater antenna sources.
With that said, we need to consider actions to reduce radiation exposure, including the use of a laptop radiation shield. It continues, “However, many in vitro, in vivo and epidemiological studies demonstrate that significant harmful biological effects occur from non-thermal RF exposure and satisfy Hill’s criteria of causality.
It concludes, “Because of the well documented studies showing adverse effects on health and the not fully understood quantum field effect, AAEM calls for exercising precaution with regard to EMF, RF and general frequency exposure. We need to minimize health dangers from constant exposure until technology inherently becomes safer.

Working on towers is often regarded as the most dangerous job in America, and the statistics for fatal accidents don’t make pleasant reading. The result is that even the most experienced professional takes unnecessary risks every now and again, which can lead to avoidable accidents, so it always worth reassessing the common problems faced by tower and antenna engineers.

Quite a few tower professionals will admit to having taken a chance while working at height during some point in their career, but in doing so they are risking their lives. While EPA rules mean than all roofing material should now be asbestos free, you cannot take for granted that the building you are working on has no asbestos. The most obvious threat posed by weather systems to anybody working at height is of course lightning.
In hot weather, burns are possible too, so when it is very cold or hot, check the temperature of the antenna or tower before ascension and always wear protection.
Barrie Trower, a British physicist and microwave weapons expert has been sharing his experiences on the subject to audiences considering WiFi in the classroom.
Protecting yourself using an Electromagnetic Radiation (EMR) shield from devices at zero distance from the body will eliminate the worst dangers the WiFi transmitter can deliver. He says that WiFi signals are equal to those used in microwave weapons and that they are threats to humans, particularly the elderly and children. Additionally, he points out that Electromagnetic Radiation (EMR) can give us headaches, disrupt our sleep, open us up to infection and create fatigue. When directly near the router transmitters, children are exposed to the strongest signal the equipment can emit. Maybe you are traveling, or maybe your university offers WiFi, or maybe you just have a WiFi router you use at home. Keep your distance from radiating sources or use laptop radiation protection when using laptop computers, tablets and other handheld devices that contain WiFi transmitters that emit Electromagnetic Radiation (EMR).
Khurana fears the potential lethal prognosis which may be waiting for those who constantly have a mobile phone held (or strapped) to their heads.
The decrease in sperm parameters was dependent on the duration of daily exposure to cell phones and independent of the initial semen quality. A massive study by the universities of California, Los Angeles (UCLA) and Aarhus, Denmark of over 13,000 children from birth up to age seven has shown that pregnant women using cell phone handsets just two or three times a day was enough to raise the risk of their babies developing hyperactivity and difficulties with behavior, emotions and relationships by the time they reached school age.
Microwave ovens use the identical 2.4 GHz frequency to cook food by penetrating the food and oscillating (heating up) the cells until the food is fully prepared. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. Therefore, safe working practice to eliminate the risk of injury or death has to be at the forefront of everybody’s mind in an industry fraught with danger. If there is a suspicion that asbestos could be present, and you are planning to disturb roofing material, extreme caution needs to be taken. Feeling tired can lead to mistakes, so if a journey has drained you, take time to have a coffee, stretch your legs, or even take a short nap if necessary. He goes on to say that, in high concentrations and over large durations of time, it has been documented that these radiations can cause cancers, like leukemia. Khurana has published a study in which he links cell phone usage to an increased risk of brain cancer. The research also indicates that the risk is even greater if the children themselves used the cell phones before age seven. The WiFi 2.4 GHz may be less intense, but can be considered a thermal and non-thermal exposure which can heat up cells and generate reasonably high current flow in the body and create potential health dangers.
However, when it comes to analyzing potential hazards, there is no single one-size-fits-all assessment plan.
Be sure that the EPA or a certified industrial asbestos removal company has done an appropriate survey.
While the tower may be protected by a lightning dissipation system, somebody working on the tower won’t be protected from stray, potentially lethal, discharges. Furthermore, for anybody in such a physical job, it also helps to keep yourself in shape and take care of your overall health and fitness, which can reduce the risk of something untoward happening when up a tower, mast or antenna.
As a good rule of thumb, at four foot away, exposure levels and associated health dangers are greatly reduced.
The most intense exposure is when you electronic device is on your lap at zero distance away from the body.
He also suggests that mobile phones could one day be responsible for more cancer deaths than either cigarette smoking or asbestos exposure. That’s right, it is that low because in nature, there is no natural source of Radio Frequency (RF) radiation. Ironically, the FCC only considers thermal effects of exposure, not the non-thermal impacts which have proven to have many health impacts. For modern buildings, constructed since 1989, there shouldn’t be a problem, but when in doubt, seek guidance. It takes years for the blood-brain barrier to form, leaving children more prone to cell-leakage from microwave radiation.” When visiting children in schools, he notes that WiFi exposure is causing health problems that include, nausea, headaches and vision problems. However, in some locations, the speed at which storm clouds can gather is easy to underestimate. He further says, “Children have less dense bones, immature immune systems and, by virtue of their size, they can act as aerials.
Putting an Electromagnetic Radiation (EMR) shield between you and the device removes the worst of the exposure danger. Please leave your phone number if you select shipping method with USA Express or International Express Mail.
