7.1 Adherence to legislative requirements on chemical substances. Annex 1 of the Blade Repair Standard specify several consumable materials which are subject to national and international pieces of chemical substance legislative regulation. The Training Provider must incorporate legal requirements on chemical substances into the training in a way so that course participants are able to carry out their duties globally. This including the following regions: • EU countries • United States & Canada • Australia • China V6 Note: It is not possible to fail the phase test (Lesson 17). The instructor can use the participation assessment form as an evaluation tool and provide constructive feedback, if the phase test reveals that the participant hasn’t reached the learning objectives.
