This chapter shall govern the manufacture, storage, handling and use of pyroxylin plastic, except cellulose nitrate motion picture film, which shall comply with the requirements of FC306.
Permits shall be required as set forth in FC105.6.
Pyroxylin plastics shall be manufactured, stored, handled and used in accordance with this chapter.
It shall be unlawful to:

1. Manufacture raw pyroxylin plastics.

2. Store raw pyroxylin plastics, except accessory storage authorized by a special permit pursuant to Section 42-276 of the Zoning Resolution.
The handling and use of raw pyroxylin plastics in quantities requiring a permit shall be under the personal supervision of a certificate of fitness holder. The storage of raw pyroxylin plastics in quantities requiring a permit shall be under the general supervision of a certificate of fitness holder.
The following terms shall, for the purposes of this chapter and as used elsewhere in this code, have the meanings shown herein.

FINISHED PYROXYLIN PLASTIC PRODUCTS. Any product to which a pyroxylin plastic has been applied that does not require further manufacturing with respect to the application of such pyroxylin plastic or any further application of pyroxylin plastic.

PYROXYLIN PLASTIC. Any plastic substance, material or compound, other than cellulose nitrate film, that has soluble cotton or similar cellulose nitrate as a base, by whatever name known, in the form of blocks, sheets, tubes or other fabricated shapes, including raw pyroxylin plastics and finished pyroxylin plastic products.

RAW PYROXYLIN PLASTIC. Any pyroxylin plastic in the form of blocks, slabs, rods tubes or other shapes, that is to be used in a manufacturing process.
Finished pyroxylin plastic products displayed in areas to which the public has access shall be placed on tables not more than 3 feet (914 mm) wide and 10 feet (3048 mm) long. Tables shall be spaced at least 3 feet (914 mm) apart. Where articles are displayed on counters, they shall be arranged in a like manner.
Spaces underneath tables on which finished pyroxylin plastic products are displayed shall be kept free from storage of any kind and accumulation of rubbish or other combustible waste or any other combustible material.
Tables on which finished pyroxylin plastic products are displayed shall be so located that in the event of a fire at the table, the table will not interfere with any means of egress.
Lighting shall not be located directly above pyroxylin plastics, unless provided with a suitable guard to prevent heated particles or broken bulb elements from falling.
Pyroxylin plastics in a Group F building shall be stored, handled and used in accordance with FC 4204.1.1 through 4204.1.7.
Where raw pyroxylin plastics in excess of 25 pounds (11 kg) are received in a building or fire area, an approved vented cabinet or approved vented vault protected by a sprinkler system shall be provided for the storage of material.
Storage in any one workroom shall not exceed 1,000 pounds (454 kg) of raw pyroxylin plastics. A storage cabinet shall not contain more than 500 pounds (227 kg). Each compartment shall not contain more than 250 pounds (114 kg).
Raw pyroxylin plastics in excess of that allowed by FC4204.1.2 shall be kept in vented vaults not exceeding 1,500-cubic-foot capacity (43 m3) of total vault space, and with construction, venting and sprinkler system protection approved by the commissioner.
Pyroxylin plastics shall not be stored within 2 feet (610 mm) of heat-producing appliances, steam pipes, radiators or chimneys.
In factories manufacturing pyroxylin plastic products, approved vented cabinets, vaults or storage rooms protected by a sprinkler system shall be provided to prevent the accumulation in workrooms of raw pyroxylin plastics in process and finished pyroxylin plastic products.
In workrooms of factories manufacturing finished pyroxylin plastic products, operators shall not be stationed closer together than 3 feet (914 mm), and the amount of material per operator shall not exceed one-shift's supply and shall be limited to the capacity of three tote boxes, including material awaiting removal or use.
Waste pyroxylin plastics, such as shavings, chips, turnings, sawdust, edgings and trimmings, shall be kept under water in metal receptacles until removed from the premises.
The storage, handling or use of pyroxylin plastic in quantities exceeding 100 pounds (45 kg) shall be located in a building or part thereof protected throughout by a sprinkler system, except for storage exclusively of finished pyroxylin plastic products in a quantity not exceeding 6,000 pounds (2724 kg).
Sources of ignition shall not be allowed in rooms in which pyroxylin plastics in excess of 25 pounds (11 kg) are stored, handled or used.
Rooms in which pyroxylin plastics are handled or stored shall be heated by low-pressure steam or hot water radiators. Radiators shall be not less than 4 inches (102 mm) above the floor. All steam pipes and risers within 6 feet (1829 mm) of the floor shall be protected with noncombustible pipe covering. All heating radiators, coils, boilers, pipes and other heating apparatus situated so as to come in contact with any combustible material, including the tops of radiators, shall be protected with 1/4-inch (6-mm) mesh galvanized steel of No. 20 U.S. gauge or equivalent. The tops of such guards shall slope so as to prevent their use as a shelf.
It shall be unlawful to store, handle or use raw pyroxylin plastics as follows:

1. In any building situated within 50 feet (15 240 mm) of the nearest wall of a building occupied as a school, hospital, or Group A occupancy.

2. In any Group R occupancy.

3. In any building of combustible construction as defined in Section 602 of the Building Code.
Raw pyroxylin plastics shall be treated as a Class IV material as defined in Section 42-272 of the Zoning Resolution. Raw pyroxylin plastics may be utilized in manufacturing processes or other production in manufacturing districts only when authorized by a special permit pursuant to Section 42-276 of the Zoning Resolution.
