For many passers Russians take to the streets in the middle of March when spring arrives, the temperature begins to rise and the snow to disappear requires attention not only to the icy, slippery floor to the heights but also because of the protruding ends of the buildings is usually the formation of long needles of ice (Сосульки-sasúlki-in Russian) that forced many times their own weight fall as real bullets on the floor or whatever in their path that beyond people may be parked cars, street stalls, bus stops, signs or other facilities of shops if they do not hang the same electrical wiring risking collapse it.
The needle is a stalactite of ice that can form on the edges of protruding objects, such as rock ledges, gorges, wires, tree limbs and cavities underground. They are usually presented in a conical tapered end only a few millimeters.
needles often have thickened rings to be lost over time as the needle is gaining a much more smoothed.
The truth is that the needles can be formed even in November, late fall-o, or as late as in April because of heavy snow conditions on the roof and slightly above zero temperatures are not uniform across the vast Russian territory its surface and climatic variations of each an-or can make a winter quite different from that of an-o prior. Additionally, the fusion of the accumulated snow lying on a roof can also be artificially produced by the same heat away from the top floor of a building if the roof does not have thermal insulation, or presence of any chimney or tube throw hot steam and warm up the environment of roof snow melting around her.
happen in autumn or winter or spring, the process is similar:
1. The snow on the roof, usually on the side facing the south, it melts when the temperature rises from 0 º C to the action of sunlight or forced by the heat from the building.
2. The melted water trickles edges of the roof.
3. Back to freeze if the temperature at the edges is below zero that could be caused by the presence of shade in this area or lack of heating at the edges of the building so that gutters acquire the room temperature.
These needles that sometimes weigh up to 300 kilos can sometimes gain weight in several dozen kilos in one day. A needle of only 2 kilos falling from a 5th floor will impact the ground or to stop it in its fall at a speed of 60 km / hr.
The reasons for his fall from a building are varied: rising temperatures and melting ice, strong wind or increase additional weight when snow sticks. The phenomenon of the fall is, on average, typical of late February in the European sector of Russia when the temperature begins to rise and the snow begins to melt but it can also happen in January forced by the weight of the ice column.
The effects on the city according to statistics from the Moscow authorities as a result of the fall of needles of ice from the roofs between 4-7 people die each year, regardless of which seriously injured . The problem is especially relevant in high-ceilinged old houses of which only the center of Moscow there are 3 000.
His removal There are cities in Russia whose municipal authorities hired crews of workers for the removal of ice from the roofs, however, there are also supporters not to intervene directly as the cleaning of the roofs are often damaged the roof as the ice can be removed only with axes and metal bars besides the removal of ice in these circumstances is very dangerous for the slippery surface and the height where a fall.
While people complain against deficiency in the work of municipal services often these simply become overwhelmed by the excess of such needles besides that no residents of a building most gladly remove ice crystallized from their balconies as threatening to pedestrians crossing the sidewalk. However, the problem becomes more difficult to solve when it comes to abandoned homes.
A very simple solution to prevent the formation of these needles is to not install the water evacuation chutes at the end of the roof but a little earlier so that the water flow along the ledge without achieving become ice needle as is done in many buildings in Czech Republic and Germany. There are also more modern heating systems to prevent ice formation on the surface of the roof and gutters.
Stories Recent accidents On 29 March in the city of Perm, Katya Bezgudova 16 an-os left his house to dump the garbage and was hit by a block of ice that fell on his head from the roof of the 4th floor the building: "I took the head in his hands and felt like the blood ran."

Another case:
Ice Needle feet drilled a stroller in which her mother, Eva Kashkova 32-an-os, had recently made his small daughter Dasha. "I heard a noise similar to when a slit with her hands a piece of cloth thickness. At first I thought the car's canvas was interrupted by the cold "
