Preventing defeating of protective devices on machinery –
Tuition modules for accident prevention

These tuition modules are intended to assist occupational safety and health speakers seeking to address the subject of the defeating of protective devices on machinery during talks for manufacturers and operators of machinery, OSH professionals and labour inspectors. In addition to an introductory module, special modules are available for personnel involved in the design and operation of machinery:

The modules take the form of Powerpoint files. The speaker’s notes for each file contain further information supplementing the content of the slides. The modules can be used in their entirety or selectively as required. Speakers therefore decide for themselves how much time to devote to the subject of tampering and in what depth to address it in their talks, and can adjust their talk to the audience.

The tuition modules use examples of machines from particular sectors. The principles communicated in this way can be transferred to other sectors. Experience has shown however that participants in further training prefer examples from the area of activity with which they are familiar. Consequently, if you have added slides of your own, we would appreciate receiving them in order for us to extend the tuition modules.
