4g cell phone jammer Control tanks and piping elevation stations should use horizontal underground casing can avoid the oil level in the tank above the floor, the tanker oil leakage, the intake pipe is difficult to drain the oil, the oil tank back and other issues. http://www.4gcellphonejammers.com/
Tank inlet pipe to set up two slopes, closed mouth pipe unloading angle of not less than 30 degrees, the rest of the pipe slope of not less than two thousandths, tubing slope tank. Installation location mouth sealed unloading tanker unloading port should be lower than 15cm or more. 4g cell phone jammer This ensures that the oil tanker after closing the valve, the ports can rapidly discharge pipe into the tank, so that the oil will not drain.
2.5 to eliminate static electricity hazards of oil in transport, handling, filling process, due to friction and static electricity, the voltage can be up to hundreds of thousands of volts, improper handling could easily lead to discharge, causing an explosion burn accident. Static conditions lead to fire and explosion is equipped to produce an electrostatic charge; possess a spark discharge voltage; there is proper clearance can cause a spark discharge; has enough energy to produce a spark; surrounding environment has explosive mixture.
Above these five conditions are met, will lead to an accident. Install anti-static grounding device should station. After arriving at the gas station tanker must stand for 10min or more, so the charge gradually decay; open the front lid must first be grounded; natural hot, dry, low-pressure spray of water should be in; work in explosion hazardous areas should antistatic wear uniforms, their underwear and coats should all be anti-static; must put an end to splash style unloading, do not allow the unloading hose is inserted Guankou unloading, unloading pipe must be thoroughly sealed bottom of the tank, the height from the bottom of the tank must not be greater than 20cm , made L-shaped front, the oil flow, steady; advocate gravity unloading, try to avoid working with pump; prohibit the use of gasoline tanker filling directly into the plastic container. Offloading tankers should ensure reliable grounding. Should gradually promote the use of static grounding device with a self-locking alarm function, improve the reliability of electrostatic discharge guide.
2.6 petrol stations should be equipped to prevent lightning air terminals, down conductors and grounding devices. Around in the open, building structures prominent stations should be installed lightning rod. Take place at least two tanks, tanks, piping, flanges and other metal accessories are electrically connected and grounded. Thunderstorms should stop unloading operations, refueling tanker parked on the ground should be done to protect. 4g cell phone jammer
2.7 Control of electrical ignition sources must be used within the gas station explosion hazardous areas than or equal to the corresponding region of the oil vapor levels or groups of explosion-proof electrical equipment. Wire connections, laying required to reach the explosion. Non-electrical explosion hazardous areas should also be explosion-proof electrical appliances. Lighting should be selected under the protective canopy type. Gas station explosion hazardous areas with caution mobile and portable appliances, prohibited the use of cell phones, pagers, computers and other non-explosion-proof electrical appliances. Electrical stations should strengthen examination and supervision of the use of prohibited private pull random access, illegal electricity. 4g cell phone jammer
2.8 Control of fire fixed flame source source control, according to the safety authority control spacing, additional safety intervals, so that the accumulation of oil and gas at the source can not Xianghuo fire source can not be distributed to the explosion hazard area. Control repair and fireworks, the business should not be used during electric welding, gas cutting, fire-fighting equipment shall be provided when the flare repair, fire monitoring in place. Refueling area must prohibit smoking ban open flame.
