Besides General training which is mandatory for all industrial and professional users, the regulators distinguish between Intermediate Training and Advanced Training depending on the risk of exposure related to the task(s) performed by the employee.
Completing the General Training takes about 40-50 minutes and at the end the trainee takes a multiple choice test which leads to a certificate valid for 5 years.
To complete the training and receive a certificate please register using the abovelink that will be with the minimum cost as well. For further information on regulation please visit : https://eur-lex.europa.eu/eli/reg/2020/1149/oj
