Construction safety training

Why can’t the gas cylinder be inverted in the tunnel? 1.

Common hidden dangers of gas cylinders: wrong use of gas cylinder rubber hose, damaged rubber hose, illegal use of propane without anti dumping device, illegal use of liquefied gas interface, damage of oxygen cylinder pressure gauge, illegal use of liquefied gas, inverted oxygen cylinder, insufficient safety distance, wrong use of rubber hose, insufficient safety distance, wrong use of rubber hose, lack of fire-fighting equipment, and unauthorized processing of propane The steel ring of oxygen mixed loading and mixed transportation gas cylinder is cracked, the pressure gauge of the pressure reducing valve is damaged, the rubber hose is not connected with a special clamp, and there is no anti dumping device.

As powerful as a bomb! What can we do to keep us safe? What can we do when danger comes? Run away in a panic! That’s running away? There is nothing wrong with this idea, because it is human instinct! The instinct to seek good fortune and avoid evil! Is the danger far from us? Maybe when we go shopping! Maybe when we ride an electric car! Maybe when we can’t think of it! Nearly a hundred gas cylinders exploded! Barbaric loading and unloading of gas cylinders , direct explosion to death , gas cylinder explosion , 6 deaths , liquefied gas cylinder leakage explosion , 2 deaths and 4 injuries to pieces , most domestic liquefied gas cylinders are 15kg, which is 10 times the power of military TNT explosive and can easily blow up a two-story building.

The upside down of gas cylinder is very easy to cause collision and cause excitation energy, resulting in accidents.

In order to stabilize the storage of acetylene, the acetylene cylinder is generally equipped with porous filler and acetone.

Hose configuration of gas cylinder? According to the national standard GB / t2550-2016 gas welding equipment – Rubber hoses for welding, cutting and similar operations, other rigid provisions of gas cylinders? Follow this! Safety learning and training of gas cylinders (some videos and pictures come from the Internet.

If it is inverted, it is easy to flow out with acetylene, which increases the consumption of acetone, reduces the service life of acetylene cylinder, affects the combustion temperature (use) of acetylene, and increases the possibility of acetylene tempering and explosion accidents caused by tempering; 3.

In case of infringement, please contact and delete them in time)..

Safety distance of gas cylinder? Various standards and specifications are relatively not unified, but the unified standard requirements for building construction are: the safe distance between acetylene cylinder and oxygen cylinder refers to that the oxygen cylinder and acetylene cylinder shall be kept 10m away from the hot work point during construction, and the distance between oxygen cylinder and acetylene cylinder shall be kept more than 5m.

When the gas cylinder is upside down, it is easy to damage the pressure reducer, flame arrester or pull off the rubber hose, resulting in the outward discharge of gas, resulting in combustion and explosion; 2.
