WARNING: If a presence of liquid gasoline is detected, continue with the section titled Hull Washout Procedure. B. Locate hand hole cover either in the deck of the control console or the deck of the backrest storage cabinet. On the 27 Foot models, also locate the hand hole upon the deck of the aft buoyancy. Remove the hand hole cover hex screws. Remove hand hole cover(s). Some flammable decomposition vapors may be present. Rotate cover approximately 45 degrees to provide sample probe access while limiting the disrupting effect of a ventilation fan upon the hull void space vapors. 5. Sample void space through hand hole. If the void space lower explosive limit (LEL) vapor reading is less than NSTM standards, continue with the next step. WARNING: If the void space vapor exceeds NSTM Standards, continue with the section titled Hull Ventilation Procedure. 6. Insert and secure the 3/8? N2 inerting hose fitting into the inspection port located centerline below the step transom. On the 27 Foot model this fitting is located within the aft buoyancy chamber. 7.
