INTRODUCTION
The Confined Space Entry Workshop based on this manual
covers five days at the Ministry of the Environment Training
Facilities. The workshop consists of lectures, demonstrations
and hands-on training in confined space entry and procedures.
The principal objective of the workshop is to teach the
confined space worker safe practices and procedures required for
entry into confined spaces. The lesson objectives are clearly
outlined at the beginning of each topic, and inform the trainee
of what he should know or do after having covered that topic. In
order to successfully complete the workshop, an overall average
of 70% is required, based upon daily tests, hands-on performance
and a final exam.
