20.1728 Welding and burning—Protective coverings and shields.
(a) Welding or burning operations shall not be conducted around hatches or companion-ways unless they are sealed with their own cover or door. In the event this is not possible, an asbestos blanket or other flameproof material may be provided in their place. Such substitution shall meet with the approval of the inspecting authority issuing the permit.
(b) When welding or burning is being conducted in locations in which sparks could fly over the outside of the ship’s hull, a protective shield composed of metal or other flameproof material shall be provided to prevent sparks from igniting the wharf or dock, barges, or oil slicks on the water, or any other combustible materials.History: 1962, PL 7-27.
