In our country, in foreign countries, petroleum, petroleum products, natural gas, mines, chemicals and industrial branches such as these, under normal operating conditions in various failures or maintenance situations are exposed to flammable and explosive environment due to gases or vapors. Businesses must take the necessary measures to avoid these situations. Otherwise, there are explosions in the workplaces and great damages and damages occur in terms of human health and property safety.
Preventing the formation of flammable and explosive environments, or at least taking precautions to minimize their effects, means avoiding many possible accidents. Businesses operating in the sectors with this risk should take general security measures and implement them at the same time. It is also a legal obligation. Businesses should consider a few important points when making risk assessments. For example, the possibility of a flammable and explosive environment and its continuity, the presence of sources of ignition including static electricity, the business processes of enterprises and their interactions and the magnitude of the impact of the explosion.
In this regard, regular checks of storage tanks for flammable, explosive, dangerous and harmful substances in the establishments are of great importance. The Regulation on Health and Safety Conditions in the Use of Work Equipment issued by the Ministry of Labor and Social Security accepts such tanks in the group of pressure vessels and installations. In this respect, said storage tanks should be inspected and inspected at least once a year by authorized mechanical engineers, high technicians and machine technicians.
Hydrostatic tests, which are the basic principle of these checks, should be applied and if no other criteria are specified in the standards, they should be done with 1,5 times the operating pressure of the tanks. However, if the hydrostatic test cannot be carried out in the compulsory cases caused by the operation, non-destructive testing methods specified in the standards should be applied again. published standards and test methods.
