The Most Dangerous Places in Europe

!±8± The Most Dangerous Places in Europe

The last summer brought an exhausting sequence of disasters throughout the Europe. The forest fires damaged at least a half of Europe, even the resort places popular among tourists. What the fire didn't manage to destroy was added by the floods.

The reason of the fires was extremely hot weather. In Hungary, Bulgaria and Romania the air temperature reached the level of +45C; more than 650 thousand people passed away because of acute conditions and cardiac arrests as well as because of direct sunstrokes. There were about 19 thousand people hospitalized in Romania.

In Slovakia the heat was the reason of snake invasion, in Spain- mice invasion, which have consumed the vegetable crop seeds in Castilla y Leon and have reached the border of the famous wine making province Rioja.

Such a burning weather became the reason of numerous fires. On the 7th of august only there were registered 236 large-scale ignitions, mostly in southern regions. In Lazio and Toscana the forests still burn; before the tourists used to walk there. In the middle of June the fires in the resort areas of Apulia, Campania, Calabria and Abruzzi were the reason of an urgent evacuation of approximately 4 thousand people. At Sardinia and Sicilia have been evacuated at least a few campsites and hotels.

During the July- August there were registered almost 2 thousand fires. For the most part it was the North area of the country and the Peloponnese peninsula which suffered. The fire almost got to the Affine; it caused the evacuation of a child-camp, 5 villages and 2 monasteries. At the same moment due tot the heat Greece suffered from electricity interruption which almost led to energy crisis.

Till this very moment the South of France is on fire. The intense smoke generation even interferes with the traffic. The city of Verdon was also captured in the fire circle.

While one part of Europe was being burnt by the sun, the other part was being flooded by rains. At the end of June the heavy-showers went straight through England having destroyed most of communication cubs. In the shire of Glostershire more than 400 people were left without electricity. The flood had also affected the sewerage activity. The most frightening thing is that the foot-and-mouth disease began to spread all over Great Britain. What will be the consequences for the country's economics- is difficult to predict.

Last week the rains had penetrated Germany as well. On 11th of august only had fallen the monthly norm of precipitations. The lands of Baden-Wurttemberg, Shelving- Goldstein, North Rein- Westville and Thuringia and Berlin were submerged. The Berlin airport Tegel had interrupted its work; the Autobahn A-5 was flooded. In a series of places some of the trailers were carried away. People are evacuated from the seaside villages and campsites. On the local authorities' reports in some areas the water level is waist-high. On the Rein the water crafts and the ferry activity is stopped; the traffic is also jammed along the river in the famous valley of castles. The culmination evening of the fireworks festival is doubtful; this year it was supposed to be held on the Middle Rein near the city of Koblenz.

In Switzerland the floods have enveloped Zurich, Basel, Sankt- Galen and the central part of the country. The inhabitants evacuate from the villages and the tourists are being rescued from the campsites. The rivers have overflown the banks; the authorities are opening the locks and dams, inundating the fields in order to save the built-up area. The flood damage is now more than 80 million dollars.

At the South of Spain the tourists had to be urgently evacuated from the campsite, they were nearly washed out with the water bursting from sky. In Barcelona the activity of the local trains was interrupted, particularly at the line which connects Barcelona with the international airport "Pratt".

The world has gone crazy. In Toscana the fires and heat is exchanged into strong rains and wind followed by coarse hail. In Florence was damaged the roof of the Uffizi gallery. At the same period of time in Milan some districts were left without electricity. The water in the city rose up to 1 meter and the traffic was paralyzed.

In Piedmont in Alps the snow fell, the temperature in the province of Cuneo was sometimes below zero and in Turin after 20C fell till 12-13C. The wind was so strong that it was tearing away the house roofs and uprooting the trees. The great snowfall blocked the motorway №27 which connects Italy and Switzerland.

At the North of France the fields are inundated, in some parts the highways were cut off. At the East of France is the Danger of the Rein's rise- the local authorities have declared 3 departments to be of a high danger.
After several weeks of heat in Romania for a couple of days the rain just wouldn't stop. One person is perished, several are considered missing. In the resort city Constanta over 400 houses are inundated. The streets have turned into full-flowing rivers, the traffic is stopped. Thousands of people are left without electricity. In village areas almost all the important roads are washed out, the bridges are destroyed.

On the 13th of august Bucharest was struck by a huge hurricane- one person dead, 10- wounded, the lifesavers had to help people out of the ruins of houses. The traffic is stopped at the most significant highways, several dozens of automobiles are damaged. The rain shower had partially inundated underground auto tunnels.

In the North of Bulgaria because of the floods 5 people died and 5 are considered missing. The rain showers were the reason for electricity interruption, damages of houses and highways.

A strong rain shower caused floods at the North of Greece, a part of houses is heated a little, and the main problems appeared in suburbs of Salonika and Alexandropoulos.

Apparently ecologists have good reasons to forebode the bride future for the present colder resorts. When during summer all over Europe the heat will reach the level of 40-50C, in northern countries the temperature will "only" raise till 30C and all the tourists will rush there.

Snow Guards For Metal Roofing - Minimize Liability by Preventing Dangerous Snow and Ice Slides

!±8± Snow Guards For Metal Roofing - Minimize Liability by Preventing Dangerous Snow and Ice Slides

In colder climates, contractors and owners of buildings with metal roofs should consider the potential liability of a snow and ice avalanche after any winter storm. When the weather breaks and the sun emerges, it melts the ice on the surface of the roof panel. Water from the snow melt creates a lubricant which is the catalyst for snow and ice to slide. These dangerous avalanches could potentially cause injury or death to pedestrians, bend gutters, destroy automobiles, HVAC equipment, livestock and other property below.

With over 32 years experience supplying snow guards to the post frame industry, we have found that there are several important factors to consider when selecting the proper snow guard for metal roofing applications. The most important features to consider are the height, width and shape of a snow guard or rail system. This determines its ability to hold back layers of heavy ice and snow. A pad style guard should have a flat, forward mounted face that measures at least 3 inches across and stands no less than 2.5 inches high. It must be mounted in the lowest portion of the roofing panel where the snow and ice actually moves, not on a high seam above the problem area. Snow guards mounted on a high seam will cease to be effective once the snow and ice compacts on the panel and becomes lower than the guard. A bar or rail system should always have a flat face or square tube with an ice stopper, at least 3 inches wide, mounted perpendicular to the panel flat. Installing the correct type of ice stopping device is the key to keeping the snow and ice from going under and over the bar.

The two most common types of snow retention systems today are the pad style guards which mount in the panel flats and the rail systems which crimp to the seams. On standing seam floating panels, adhesive mounting is the preferred method of attachment for pad style snow guards. This mounting method does not restrict the natural thermal expansion and contraction process of floating metal roof panels and in the event of severe snow drifting conditions, it provides a release feature that eliminates the possibility of panel damage. The other method is a crimp on snow guard or rail system. It is very important to remember that crimp on guards or rails have no release aspect and panel damage could occur if snow loads exceed the design capabilities of the clamp. Therefore, these systems should always be installed in strict accordance with the manufacturers recommendations!

Another noteworthy consideration is the type of material from which the snow guard is made. Clear polycarbonate is virtually invisible and will not create corrosive galvanic reactions caused by dissimilar metals exposed to outdoor elements. Because all plastics do not maintain the same characteristics when exposed to various weather conditions, the consumer should only consider using a product made from a virgin grade, UV stabilized, prime polycarbonate material. Our company uses the same type of polycarbonate, approved by NASA, used to make astronaut face masks.

Something else to consider, clear pad style snow guards are far less noticeable on a roof than colored ones. A color matched snow guard will act as a sundial and cast a conspicuous shadow. Think about this scenario, a person is standing in front of a building and is looking up at the roof. What do they see? They observe all the protruding objects that do not blend with the sky, including nontransparent snow retention systems. Clear snow guards unify with the skyline and in most cases, are almost undetectable.

With so many snow retention choices on the market today, it may be difficult to choose the correct system for your roof because there is not just one type of snow retention system that is perfect for every application. Some types of metal roofing do not have the proper seam height and are not structurally suitable for use with a clamp down system. While it is usually harmless to the panel to use an adhesive mounted system, weather conditions may not always be ideal for immediate installation.

When it really comes down to it, choosing an experienced manufacturer and following their instructions and spacing recommendations is the key to a successful snow guard installation.
