§ 146.01-15 Maintenance of emergency equipment.

The emergency equipment provided, regardless of whether or not required by this subchapter, shall be maintained in good condition at all times.

(b) Use. Approved buoyant work vests are considered to be items of safety apparel and may be carried aboard artificial islands or fixed structures to be worn by persons employed thereon when working near or over the water under favorable work conditions. The use and control of such vests shall be under the supervision of the person in charge of the platform. When carried, such vests shall not be accepted in lieu of any portion of the required number of approved life preservers and shall not be substituted for the approved life preservers required to be worn during drills and emergencies.

(c) Stowage. (1) The work vests shall be stowed separately from the regular stowage of approved life preservers.

(2) The location for the stowage of work vests shall be such as not to be easily confused with that for approved life preservers.

Subpart 147.01-Purpose and Delegation

fixed

§ 147.01-1 Purpose of safety zones. Safety zones may be established around artificial islands and structures being constructed, maintained, or operated on the Outer Continental Shelf to promote the safety of life and property on the islands and structures, their appurtenances and attending vessels, and on the adjacent waters within the safety zones. Regulations adopted for safety zones may extend to the prevention or control of specific activities and access by vessels or persons, and include measures to protect the living resources of the sea from harmful agents. The regulations do not encompass the operating equipment or procedures used in the drilling for and production of oil, gas, or other minerals, or the transportation of oil, gas, or other minerals by pipeline except as they relate to the safety of life and property on the islands and structures and on the waters adjacent

§ 147.03-1 Initial action by the district commander.

Whenever it comes to the attention of the district commander that a safety zone and regulations may be required concerning an artificial island or fixed structure being constructed, maintained, or operated on the Outer Continental Shelf or its appurtenances and attending vessels, or the adjacent waters, he may initiate appropriate inquiry to determine whether a safety zone and regulations should be established. In making this determination, the district commander considers all relevant safety factors, including existing or reasonably foreseeable congestion of vessels, the presence of unusually harmful or hazardous substances, and any obstructions within 500 meters of an artificial island or fixed structure. If the district commander determines that the circumstances warrant the establishment of a safety zone and regulations he takes action as he deems necessary consistent with the provisions of this part.
