PLEASE NOTE: The practical component of the Enter and Work in Confined Space requires entry into a confined space at ground level as well as at a height above the ground. If the participant does NOT have a current Work Safely at Heights Certificate, they will be only able to participate in the ground level activity.  This will not impede the participant in being competent in all areas of the training as the above heights component will be covered at ground level.
