WHO SHOULD ATTEND?

This is an advanced course, intended for electrical workers, technicians, engineers and senior engineers involved in the classification of potentially explosive atmospheres and the planning and design of electrical systems and installations in or associated with hazardous areas.

HAZARDOUS AREAS CLASSIFICATION

Competency Training’s Hazardous Areas Classification course makes up the first three days of this Hazardous Areas Classification and Design course. Students who will not be involved in the planning and design of the installation may opt to attend only the Classification section of the course.

CONDUCT A CONFORMITY ASSESSMENT

During the process of designing an electrical installation for a hazardous area, there may be times when it is impossible to get a locally certified piece of equipment. In this situation, the designer must obtain a Conformity Assessment Document for the equipment.

Competency Training’s Conduct a Conformity Assessment course is completed by Recognition of Prior Learning. It is expected that students will be able to provide evidence of having previously completed the Conformity Assessment process.
