Industrial aluminum profile in welding,sudden fire,explosion?!What is the reason?So how can we prevent it?

(1)when the welding cutting operation,especially when gas cutting,due to the use of compressed air or oxygen flow injection,the Mars,bead and iron slag splashing can(the larger bead and iron slag splash away from operating point 5 m away),when in the working environment,inflammable,explosive or gas could fire and explosion accident will happen.

The high altitude welding and cutting operation,the scope of the flammable and explosive items of Mars is not cleaned up,the operator in the process of throwing the electrode head,after the end of the operation is not carefully checked whether there is fire.

(3)gas welding,gas cutting in the process of work is not placed in accordance with the requirements of the acetylene generator,before the work is not checked according to the requirements of welding(cutting)torch,rubber pipeline and acetylene generator safety device.

(4)There are shortcomings in the formulation of gas cylinders,the storage of gas cylinders,filling,transportation,use and other aspects of the deficiencies,in violation of safe operation procedures.

The development and installation of⑸acetylene,oxygen and other pipelines are defective,and their deficiencies have not been found and corrected in time during use.

At the time of welding and repairing fuel containers and pipes,corresponding measures were not taken as required.In the implementation of replacement welding repair,replacement is not complete,in the implementation of pressure replacement welding repair pressure is not enough to lead in the external open fire.

Preventive measures:

(1)when the welding cutting operation,to 10 m within the scope of the working environment clean up all flammable and explosive items,check the working environment should be paid attention to in the gutter and drain is liquid and combustible gas,as well as the possibility of leakage into the gutter and drain flammable and explosive substances,so as to avoid accidents caused by welding slag,metal Mars disasters.

The high altitude welding and cutting,it is forbidden to throw the electrode head,the welding and cutting work below should be isolated,work should be done carefully and carefully checked,confirm that there is no fire danger before leaving the scene.

(3)The cylinders should be used in accordance with the relevant national standards and regulations,and the safe operation rules should be strictly observed in the storage,transportation and use of the cylinders.

(4)The pipeline of transporting combustible gas and combustible gas should be installed,used and managed in accordance with the provisions,and the operators and inspectors should carry out special safety technical training.

⑸welding fuel container and pipeline,should be combined with the actual situation to determine the welding repair method.When the replacement method is implemented,the replacement should be thorough,and the work should be strictly controlled to contain the shadow of the combustible material.When the replacement method is implemented with pressure,a certain voltage should be maintained as required.The oxygen content should be strictly controlled in the work.To strengthen the detection,pay attention to monitoring,to have safety organization measures.
