How to Protect Sensitive Equipment from Solar Flares

Posted on: January 15th, 2018 | Posted in: Uncategorized

Natural disasters such as hurricanes and wildfires have been causing unimaginable destruction across the country. But there is another phenomenon that has the potential to cause immeasurable damage to modern infrastructure – coronal mass ejections and solar flares.

The sun is millions of kilometres away from the earth – yet disturbances on its volatile surface can push us back into the dark ages.

Solar Flares & Coronal Mass Ejections (CME)

There are super active spots on the sun where the magnetic field is particularly concentrated. Often there are explosions around these regions which result in the ejection of a wide spectrum of radiations running the gamut from visible light to X-rays. These events are known as solar flares and based on their intensity – which is measured on a logarithmic scale – they can either expose air travellers to an increased dose of radiation or wreak havoc on GPS and satellite communication.

While solar flares are to be held in awe – coronal mass ejections (CME), often confused with solar flares are even more potent. They take a while to reach us but the directional blast comprises solar matter particles which cause distortions in the earth’s magnetic field and can cripple electrical grids.

NASA’s Response to Solar Flares and CMEs

NASA has a good idea of the repercussions of solar flares and coronal discharges. In its attempt to “keep the lights on,” it has started the Solar Shield project through which the North American grid system can identify power stations and generators that might be hit the hardest during an event so that pre-emptive and remedial measures can be put in place.

NASA is vigilant. But that doesn’t mean all industries can rest easy. A class X behemoth can still cause a lot of damage to ground equipment, especially for military, aviation and sophisticated telecommunication.

Under these circumstances EMI/RFI shielding products prove to be effective. They act as a buffer between items and the coursing electromagnetic currents ensuring the continued operation of sensitive equipment.

Vanguard has been at the forefront of this niche and is capable of supplying EMI/RFI shielding gaskets, manufactured to customer specifications.

In the competitive world of EMI/RFI shielding gaskets, many companies are touting various nickel-containing gasket materials claiming that they have improved galvanic compatibility with aluminum at a lower cost. However, these material combinations including nickel and graphite alloys, and nickel and aluminum alloys suffer from poor conductive performance. And beyond that challenge, a major concern is the uncertainty surrounding the safety of heavy exposure to nickel products.

The European Union is constantly issuing recommendations on the amount of nickel that can safely be exposed to skin. According to the Nickel Producers Environmental Research Association (NiPERA) fact sheet on Nickel and Human Health, “Nickel is one of the most common anthropogenic causes of allergic contact dermatitis (ACD).”

The fact sheet goes on to state that individuals who have prolonged exposure to nickel become more sensitive to it.

“A nickel sensitized individual, when re-exposed to nickel ions on the skin in sufficient amounts, may have an allergic response within a matter of hours. This is termed the elicitation phase, which often occurs at a lower concentration of nickel ions than required for inducing sensitization in the first place. The elicitation of nickel ACD usually occurs at the site of exposure but can occur in skin remote from the site of contact with nickel where previous nickel sensitization reactions have occurred.”

Because of these risks, it may be beneficial for companies to select industrial products that are nickel free to prevent unnecessary exposure and discomfort among employees. At Vanguard Products, the majority of our materials are nickel free, and our Ultra-Vanishield Dual Elastomer EMI/RFI Shielding Gaskets offer a competitive cost alternative to nickel-containing products. Our microbridge approach with silver and aluminum alloys can even surpass the galvanic performance of other products. And because our EMI shielding gaskets are made in the USA, all materials adhere to current safety and quality standards.
