All cargo and miscellaneous vessels must be equipped with high velocity fog applicators for use with the required combination nozzle at each station.

On container ships, an applicator termed a bayonet or piercing type utilizes a sharp tip for cutting and penetrating the metal skin of a container.

In machinery spaces, the applicators should be 10 to 12 feet in length to ensure all portions of the bilge can be effectively reached.

All of the above.
