We intended to use a vent that did not require maintenance from the roof however a larger vent with maintenance required from the roof was needed. There is no roof hatch and the roof is only accessible via a portable extension ladder. The skylight is removable to allow for removal of the pump by crane/boom truck without having to remove a portion of the roof structure. We would like to supply a fall restraint/ arrest connection in lieu of a guardrail. Page I oft
