Welding wire of solid section before giving to the welding area should be cleaned of rust, dirt and oils. Storage and transport of compressed and liquefied gas protection is carried out in steel cylinders under pressure p <20 MPa, manufactured according to gost 949-73. For transport and distribution to the welding station, argon, helium, carbon dioxide, nitrogen and hydrogen is used mainly steel cylinders with a capacity of 40 liters. Cylinders are painted in a strictly certain colors and they make the labels according to gost 949-73. To avoid an explosion of cylinders should be particularly careful to observe the rules of safe operation of vessels operating under pressure, and take action providing for avoidance of overheating and excessive pressure in them. Liquid argon is transported by rail in special rail tank cars or trucks in tanks (GOST 17518-79), as well as gasifier installations such as asu. Technical nitrogen is supplied in gaseous form in cylinders and avtoretsipientah pressure 15,0 0,5 MPa or 20,0 + 1,0 MPa or a liquid in insulated tanks. Gaseous Oxygen is transported in steel cylinders (GOST 949-73), or avtoretsipientah pressure 15,0 + 0,5 MPa or 20,0 1,0 MPa at 20 'C.

Do not use for storage and transport of other gas cylinders, and avtoretsipienty pipeline designed to transport oxygen. When loading, unloading, transportation and storage of oxygen cylinders should not be allowed to drop, knock, damage and contamination of oil. When working with hydrogen should strictly abide by safety requirements. Hydrogen is explosive. With air and oxygen, it forms an explosive mixture, mixed with oxygen (2:1) – detonating gas. Explosive limits: with air 4 75%, oxygen 4.1 96%. Auto-ignition temperature 510 'C.

Spring field work in 2009 are under the sign of the crisis. The general economic slowdown, a delay the implementation of last year's harvest and the problems with lending has put many farmers into bankruptcy. The Ministry Agriculture formed a special interagency committee, in terms of tasks which included the monitoring of sowing. Commission to provide operational assistance to governments aic Russian regions. Winter crops harvest in 2009 is filled with an area of 17.2 million hectares. Condition of crops Roshydromet assessed as good and satisfactory. Throughout the country, the poor state of winter crops (with sparse growth of threes more than 50% of plants) is expected in the area of 0.76-1.08 ha.

This will be about 4-6% of the total sown area. It is expected that the spring planting this year will take place in an area of 48 million hectares. Among them: spring grains and legumes occupy 31.3 million ha, sugar beet – 0.9 million hectares, sunflower – 5.3 million hectares By early spring sowing of spring crops, as of April 1, 2009 have moved almost all regions of the Southern Federal District. Ministry of Agriculture, referring to the data fgi Rosselhoztsentr "argues that the seeds of spring farmers provided almost completely. Condition index is estimated to be 78.8%, which is two percent above the previous year. More complex The situation with the provision of agricultural fertilizers. As of March this year, the resources of mineral fertilizers amounted to only 843 thousand tons. This is half of the needs of producers.

Technical capabilities of farmers in the Ministry of Agriculture assessed as satisfactory. In the figures: in Russia there are 522,000 tractors, 159,000 plows, cultivators 197000, 238000 planters. Willingness of agricultural machinery for the spring sowing campaign ranked higher last year. To carry out repair work on inter-regional bases and oao "Rosagrosnab" in the region have established a reserve of spare parts. Amount material and technical resources is estimated at 1.52 billion rubles. Most pronounced impact of the economic crisis affected the provision of agricultural fuels and lubricants. As of March 10 volumes supply of diesel fuel was 458.8 thousand tons (85.3% from the previous year), for motor gasoline – 109.1 thousand tons (66.4% from last year's level). The reason for this reduction could be quite a significant increase in wholesale prices. So from January 15 to March 5, the wholesale price of diesel fuel from refineries increased by 15.5%, petrol by 18.%
