Description of key information

As described in the CSR, no environmental exposure has been demonstrated during the different steps of lifecycle of CuGUN. The CuGUN is imported from United States of America in tight depressurized container by AUTOLIV. In the production line of gas generator, air and dust are aspired by a cyclonic system and then passes through a dust containment system by the water. During cleaning, pellets are removed by a specific vacuum cleaner for pyrotechnic products which contains a tank filled with water. Finally, the water that contains CuGUN is sent to a specialized company for incineration with personal protection equipment. Therefore, no release to environment is expected. When included in article, gas generator is sealed. At the outbreak of the airbag in the event of collision, all the products in the generator are burned. If some of the components should not burn, they remain confined within the generator. At waste life stage, gas generator were incinerated. Toxicity to microorganisms testing is then not necessary.
