Worker Training

Workers must be trained before they enter a confined space. The training must include
 recognizing the hazards (Including potential hazards) in the confined
space, and
 safe work practices, including the use of all equipment such as ventilation equipment, air monitors, and personal protective equipment.

It is strongly recommended that
 the employer use an evaluation procedure (a test) to ensure that workers have acquired the knowledge necessary to safely perform their duties, and
 inexperienced workers team up with experienced workers.
You must review the content of the training at least annually, and whenever there is a change in circumstances, such as a change in an industrial process. If the review indicates that the training was not adequate, you must provide additional training.
You must keep a record of the names of trainers, trainees, as well as the date of training. If the project’s joint health and safety committee or health and safety representative wants a copy of the record, you must provide one.
