All scrap metal arriving at the reception points is sorted according to several parameters. In addition to the type, type and class of metal is determined: (scrap car prices near me):
how safe it is for the environment,
Whether the metal can be used for melting,
whether the metal contains any impurities.
One of the mandatory tests is the explosion safety test.
Every batch of scrap metal that is transported, stored, or processed must have an explosion safety certification. Only specialists trained in the discipline of Scrap Metal Explosion Safety Control can inspect the metal and issue the appropriate documents. Re-certification of employees is carried out once every 3 years.
Such a measure is nece
ssary because scrap can contain shells and cartridges, pyrotechnics and fireworks, metal cylinders from gas, internal combustion engines, tanks from fuel and lubricants. During transportation and processing such metal can explode, causing considerable damage.
If an explosive item is identified in scrap, it is stored in a separate room free from temperature risks.
Another test that scrap metal undergoes is the radiation control. The test is regulated by legal regulations, which are aimed at eliminating the use of radiation metal in recycling, in the storage of scrap lots. Based on the results of the test, a specialist’s report is issued.
When there is a large volume of scrap metal or continuous intake of scrap metal, the following
Automated means: special gates, racks,
portable means: radiometers, dosimeters.
The results are recorded in a log or protocol.
Determining the hazard class
This is one of the main criteria for assessing scrap metal. There are five classes, which can affect people and the environment with varying degrees of danger:
The first class includes extremely hazardous wastes, such as those containing mercury, polonium and plutonium.
The second class includes highly hazardous scrap, which will take the ecosystem up to 30 years to fully remediate. For example, scrap containing lead or cobalt is classified as Class 2.
The third class includes scrap metal with a moderate environmental impact, after the impact of which it will take the ecosystem 10 years to recover. These are scrap metal containing copper, aluminum, and zinc.
Class 4 is low-hazard scrap, which contains bronze, cast iron.
A non-hazardous level of environmental impact has been determined for the fifth class. This group includes metal scrap that is used for recycling.
At any legally compliant metal collection point, all scrap is checked against several criteria. Only after receiving several certificates can a batch be accepted and sent to a recycling plant for further processing.
