(c) For the purposes of (d) and (e) of this subsection and subsection (7) of this section, pesticides and their containers at the loading area shall not be considered unattended during the spraying operation if the operator maintains either visual control or repeatedly returns at closely spaced intervals.
(d) Pesticides labeled with the signal word "danger/poison" and their containers shall be stored in one of the following enclosures which, when unattended, shall be so constructed and locked (except (v) below) to prevent children, unauthorized persons, livestock, or other animals from gaining entry.

(a) For purposes of this subsection, warning signs shall show the skull and crossbones symbol and the words: "Danger/Poison (or Pesticide or Chemical) Storage Area/Keep Out" in letters large enough to be legible at a distance of thirty feet.
(b) Warning signs shall be posted:
(i) On enclosures specified in subsection (6)(d) of this section, when such enclosures are unattended;
(ii) At each entrance or exit from a storage area and on each exterior wall, so that a sign is visible from any direction;
(iii) If the pesticide storage area is contained in a larger, multipurpose structure, warning signs shall be clearly visible on each exterior wall of the structure within thirty feet of the pesticide storage area and from the main entrance to the larger structure: Provided that posting of the main entrance shall not be required, if a sign is visible from the entrance which clearly identifies the possibility that pesticides may be stored on the premises, (i.e., XYZ Pest Control or XYZ Wood Treatment, Inc.);
