This chapter shall govern the manufacture, storage, handling and use of pyrophoric materials.
Permits shall be required as set forth in FC105.6.
Pyrophoric materials shall be manufactured, stored, handled and used in accordance with this chapter. Pyrophoric materials that are compressed gases shall additionally comply with the requirements of FC Chapter 30.
It shall be unlawful to:

1. Manufacture, store, handle and/or use detonable pyrophoric materials, except as specifically authorized in compliance with the requirements of FC Chapter 33.

2. Compress any pyrophoric material that is a gas.
The handling and use of pyrophoric materials in quantities requiring a permit shall be under the personal supervision of a certificate of fitness holder. The storage of pyrophoric materials in quantities requiring a permit shall be under the general supervision of a certificate of fitness holder.
The following term shall, for the purposes of this chapter and as used elsewhere in this code, have the meaning shown herein.

PYROPHORIC MATERIAL. A material with an autoignition temperature in air, at or below a temperature of 130°F (54°C).
The storage, handling and use of pyrophoric materials in amounts not exceeding the maximum allowable quantity per control area indicated in FC2703.1 shall be in accordance with FC 2701, 2703, 4101, 4103 and 4106.
Compressed gas systems conveying pyrophoric gases shall be provided with approved manual or automatic emergency shutoff valves that can be activated at each point of use and each source.
A manual or automatic fail-safe emergency shutoff valve shall be installed on supply piping at the container or other source of supply. The shutoff valve shall be operated by a remotely located manually activated shutdown control located not less than 15 feet (4572 mm) from the source of supply. Manual or automatic container valves on the containers supplying the pyrophoric material may serve as the emergency shutoff valve when the containers are the sole source of supply and are not manifolded.
A manual or automatic emergency shutoff valve shall be installed on the supply piping at the point of use or at a point where the equipment using the gas is connected to the supply system.
The storage, handling and use of pyrophoric materials in amounts exceeding the maximum allowable quantity per control area indicated in FC2703.1 shall be in accordance with FC Chapter 27 and this chapter.
Indoor storage of pyrophoric materials in amounts exceeding the maximum allowable quantity per control area indicated in FC Table 2703.1.1(1), shall be in accordance with FC 2701, 2703, 2704 and this chapter. The storage of silane gas and gas mixtures with a silane gas concentration of 1.37 percent or more by volume, shall be in accordance with CGA G-13.
In addition to the requirements of FC 2704.12, floors of storage areas containing pyrophoric liquids shall be of liquid-tight construction.
Storage of pyrophoric solids and liquids shall be limited to a maximum area of 100 square feet (9.3 m2) per pile. Storage shall not exceed 5 feet (1524 mm) in height. Individual containers shall not be stacked. Aisles between storage piles shall be a minimum of 10 feet (3048 mm) in width. Individual tanks or containers shall not exceed 500 gallons (1893 L) in capacity.
Storage of pyrophoric gases shall be in detached buildings where required by FC2703.8.2.
In addition to the requirements of FC2703.9.8, indoor storage of pyrophoric materials shall be isolated from incompatible hazardous materials by 1-hour fire barriers with openings protected in accordance with the construction codes, including the Building Code.

Exception: Storage in approved hazardous materials storage cabinets constructed in accordance with FC2703.8.7.
Outdoor storage of pyrophoric materials in amounts exceeding the maximum allowable quantity per control area indicated in FC Table 2703.1.1(3) shall be in accordance with FC 2701, 2703, 2704 and this chapter. The storage of silane gas, and gas mixtures with a silane gas concentration of 1.37 percent or more by volume, shall be in accordance with CGA G-13.
The separation of pyrophoric solids, liquids and gases from buildings, lot lines, public streets, private roads or means of egress shall be in accordance with the following:

1. Solids and liquids. Two times the separation required by FC Chapter 34 for Class IB flammable liquids.

2. Gases. The location and maximum amount of pyrophoric gas per storage area shall be in accordance with FC Table 4104.2.1.

a. The minimum required distances shall be reduced to 5 feet when protective structures having a minimum fire resistance of 2 hours interrupt the line of sight between the container and the exposure. The protective structure shall be at least 5 feet from the exposure. The configuration of the protective structure shall allow natural ventilation to prevent the accumulation of hazardous gas concentrations.
When overhead construction is provided for sheltering outdoor storage areas of pyrophoric materials, the storage areas shall be protected throughout by a fire extinguishing system.
Pyrophoric materials in amounts exceeding the maximum allowable quantity per control area indicated in FC Table 2703.1.1(1) or 2703.1.1(3) shall be handled and used in accordance with FC 2701, 2703, 2705 and this chapter.
When overhead construction is provided for sheltering of outdoor use areas of pyrophoric materials, the use areas shall be protected throughout by a fire extinguishing system.
The handling and use of silane gas, and gas mixtures with a silane gas concentration of 1.37 percent or more by volume, shall be in accordance with CGA G-13.
Pyrophoric materials classified as a Class IV material as defined in Section 42-272 of the Zoning Resolution 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.
It shall be unlawful to manufacture pyrophoric materials classified as a Class IV material as defined in Section 42-272 of the Zoning Resolution.
It shall be unlawful to store pyrophoric materials classified as a Class IV material as defined in Section 42-272 of the Zoning Resolution, except accessory storage authorized by a special permit pursuant to Section 42-276 of the Zoning Resolution.
