Haaretz reported, that at least four people were killed and 50 people were injured in an explosion a few hours ago, in a residential building, located in downtown of Netanya. Although all the circumstances of the explosion has set, previously reported, that the explosion occurred as a result of gas leaks in the building, located on the Herzl Street near Independence Square in the city of Netanya, in an area that many tourists visit.

Note, that the Israeli city of Netanya- is the largest resort on the Mediterranean coast. In the city of Netanya there are 11 hotels and 9 beaches with a total length of 13.5 km. Netanya is located in the central part of the Sharon Valley, about 30 km north of Tel Aviv and 50 kilometers south of Haifa. Along the length of the beach zone, Netanya surpasses all other cities in Israel. Also in Netanya is one of the largest centers of the diamond industry in Israel.

Israeli police spokesman Alex Kagalsky said, that the main cause of explosion in Netanya is the explosion of gas, which boomed in the first floor, where located the restaurant. Rescuers arrived on the scene, quickly extinguished the fire arose in the building and organized a search and rescue surviving of tenants, but it is assumed, that under the rubble of the building can still be dozens of people.

Although as a cause of the explosion and assumed leakage of gas, which occurred as a result of careless handling of gas appliances, but, according to Israeli newspaper The Jerusalem Post, Netanya police also suspects in this crime man, who was previously detained in the building on Thursday at attempt to dismantle the gas pipes. While under investigation, and to speak only on the preliminary versions of what happened.

According to statistics, in most cases, the cause of gas explosions are carelessness and negligence in dealing with gas and lack of elementary safety rules. Explosive of air-gas mixtures are often formed as a result of failure of gas equipment. It is therefore necessary to carry out periodic maintenance works and now the police Netanya check the frequency of preventive work in the this building.

Previously found, that the accomodation in Netanya building, where the explosion occurred, had a very small windows, which could theoretical lead to an explosion of gas by negligence, and not the result of deliberate action.

If in a building with a small area of windows, as a result of negligence, there is an outflow of gas in the air of this room there will stoichiometric mixture of natural gas with air (about 10%) and if more happens on the ignition of the mixture of gas, pressure can reach more than 0.8 MPa, while the force on the floor of the building intercommunication can reach such values, that overlap and walls will be destroyed, and are above constructions will be raised, and then came down, that is totally could collapse part of a building, there was an explosion of gas.

If in the accomodation in Netanya building was the window of sufficient size, that would have destroyed a small increase of gas pressure, then in this case has not risen to a level of gas pressure, that can destroy the floor and walls of building.

Note, that Israel's building codes regulate the size of windows and the thickness of the glass in rooms with gas equipment. In particular, the window must have a thickness of glass in them, up to 5 mm and square of windows at least 1.5 m2, and wired glass can not generally be used in these rooms with gas equipment.

Now, the Netanya police checks gas system for the presence of intentional damage. The police are expected to interrogate the gas company employees today on suspicision of negligence.

Big rescue teams evacuated the injured to hospitals in Netanya, Hadera and Kfar Saba.

On the Ground for toxic waste "Krasny Bor" near St.Petersburg, Russia fire broke out
Thursday, 23 June 2011 19:10
According to the press service of the Russian Ministry of Emergency Situations , on the Ground Krasny Bor, near St. Petersburg, fire broke out. To extinguish the fire at the present time there are about a dozen fire trucks. Chemical laboratory of Ministry of Emergency Situations is reviewing the composition of air near Ground Krasny Bor. Presumably, the fire at the Ground Krasny Bor started today at 15:43 of Moscow time.

Residents of the southern districts of St. Petersburg is recommended not to go out and close all windows until the fire at the Ground will not be completely extinguished, as the burning of organic waste leads to emissions of harmful substances for people, which are easily carried by the wind.

According to the Ministry of Emergency Situations, fire was initially assigned to the second-highest rating of five-point scale. The danger is increased due to the fact, that the Ground Krasny Bor is the only one Ground in North-West region of Russia, which stores the most dangerous organic waste. According to experts, in the cemeteries of the Ground is more than half a million tonnes of organic waste, and this mass is constantly growing. From time to time in the Russian press there are reports, that the Ground Krasny Bor is on the verge of exhaustion of the area allotted to it, which is an ecological threat to the surrounding towns.

In the process of combustion of oils produced many harmful substances. Nitrogen oxides produced by oxidation of nitrogen, are very toxic compounds. Is very harmful emissions to the atmosphere of sulfur dioxide, which has a pungent smell, but has no color. Sulphur dioxide disastrous effect on plants, especially on fruit trees and conifers, as well as for agricultural crops. In the presence of sulfur dioxide reduces the transparency of air. Carbon monoxide is very toxic. This compound is formed in the case of incomplete combustion of carbon by burning of almost all kinds of oils. Carbon monoxide has no smell and color, making it difficult to detect. Most dangerous is formaldehyde - a gas with a sharp odor, which is highly toxic.

Each year, the Ground Krasny Bor receives about 20 thousand tons of toxic wastes and products of chemical, medical, industrial enterprises of the North-West region. The area of the Ground Krasny Bor is 73 acres, it is located only 30 kilometers from St. Petersburg, and only two kilometers from the nearest village of Krasny Bor, Leningrad region.

Ground Krasny Bor has been operating for over 40 years, the choice of Ground Krasny Bor was due to the presence in this region of thick layers of clay that make it impossible to spread toxic waste landfill via groundwater.

It should be noted, that in the past at the Ground Krasny Bor also were fires. The last major fire occurred on May 24, 2008, when on Ground Krasny Bor fire broke out the barrels of fuel oil. After that, the fire spread to the another parts of Ground Krasny Bor, despite the active work of fire brigades and a few hours, the square of burning organic waste was an area of one thousand five hundred square meters, but later, in the evening, the fire was localized, and the next day completely extinguished.

All the fire is regularly carried out chemical analysis of air, which showed the concentration of combustion products does not exceed the maximum permissible concentrations of toxic substances in the air in the village of Krasny Bor and the nearest city of Kolpino. Already received information, that the fire was localized, which excludes its further spread, but the fire-fighting is still continuing. Also in the near future will begin an investigation, which will determine the damage, caused to the environment.
