F.

Interiors of pipe, fittings, and accessories shall be kept free from dirt and foreign matter.

G.

Store pipe and fittings on heavy wood blocking or platforms so they are not in contact with the ground.

H.

Pipe, fittings, and specials shall be unloaded opposite to or as close to the place where they are to be used as is practical to avoid unnecessary handling.
