Be exempted from expertise requirement under Chemicals Ozone Layer Ordinance

    In individual cases, you may be exempted from the requirement of a technical or manual training for proof of expertise in accordance with the Chemicals Ozone Layer Ordinance.

    Description

    To work on technical equipment that uses ozone-depleting substances, you must provide proof of expertise.

    For the certificate of competence, you normally complete a training course followed by an examination. The examination is offered both by state-approved, private providers and by public bodies such as chambers of industry and commerce or chambers of trade.

    To be admitted to the expert knowledge examination in certain categories, you must provide evidence of completed technical or craft training. The IHK or HWK can exempt you from this requirement if you can prove that you have acquired the prescribed craft skills elsewhere. You apply for exemption from the requirement for training in writing to your IHK or HWK.

    Exemption from the requirement for training is a procedure that depends very much on the individual case, so you should find out about your options before submitting your application to the IHK or HWK.
