F. 
Supervision. All premises in which magnesium is machined, polished or otherwise worked upon shall be under the care and supervision of one or more persons, each holding a certificate of fitness as superintendent or manager thereof. The number of persons required to hold such a certificate shall be determined by the Fire Prevention Division and stated on the required permit, but in no case shall there be required more than three at any one time on the premises.
[Amended 3-14-2000 by L.L. No. 4-2000]
When magnesium scrap is to be transported from one location to another, it shall be stored in metal containers, the capacity of which shall not exceed 55 gallons (water). Drums are to be marked MAGNESIUM SCRAP in five-inch letters. Junkyards and junk dealers shall store and keep magnesium and articles containing more than 25% of magnesium by weight in piles, bins, drums or boxes located outside any building, but this shall not prevent the roofing over such storage, but no sidewalls shall be permitted. No such storage shall individually exceed 300 square feet in the rear, and there shall be a separation of not less than five feet between such storage and the storage of any other combustible materials. Such storage, and the handling and sorting of magnesium, shall, however, be permitted in buildings complying with the above provisions for storage and workrooms, housekeeping and protection.
