3204.3 Outdoor Cryogenic Storage
JUMP TO FULL CODE CHAPTER
Outdoor storage of cryogenic containers shall be in accordance with FC 3204.3.1 through 3204.3.1.2.5.
Cryogenic containers and systems in storage or use shall be separated from materials and conditions which pose exposure hazards to or from each other in accordance with FC 3204.3.1.1 through 3204.3.1.1.5.
Stationary cryogenic containers shall be separated from exposure hazards in accordance with the minimum separation distances set forth in FC Table 3204.3.1.1.
FC TABLE 3204.3.1.1 SEPARATION OF STATIONARY CRYOGENIC CONTAINERS FROM EXPOSURE HAZARDS
FC TABLE 3204.3.1.1 SEPARATION OF STATIONARY CRYOGENIC CONTAINERS FROM EXPOSURE HAZARDS
| EXPOSURE | MINIMUM DISTANCE (feet) |
| Buildings, regardless of construction type | 1, or minimum required for service access |
| Building exit | 10 |
| Building openings other than building exits | 1 |
| Air intakes | 10 |
| Lot lines | 5 |
| Group A occupancies and other public gathering places | 50 |
| Nonambulatory patient areas | 50 |
| Combustible waste or vegetation | 15 |
| Other hazardous materials | In accordance with FC Chapter 27 |
For SI: 1 foot = 304.8 mm.
Fill connections for stationary cryogenic containers shall not be positioned closer to exposure hazards than the minimum distances required for stationary cryogenic containers. Fill connections for stationary cryogenic containers shall be located and maintained to afford cargo tank operator access to valves and indicators on the cryogenic containers and cargo tank.
The surface of the area on which stationary cryogenic containers are placed, including the surface of the area located below the point where connections are made for the purpose of filling such cryogenic containers, shall be compatible with the cryogenic fluid in the cryogenic container. The surface shall be capable of withstanding temperatures of cryogenic fluid that may be released during normal filling operations, without cracking, shifting or other impact upon the stability of the installation.
Containers of cryogenic fluids shall not be stored or used within diked areas containing other hazardous materials.
It shall be unlawful to install stationary cryogenic containers on the roof of any building or structure.
Stationary cryogenic containers, vaporizers, heat exchangers and connecting piping located in areas subject to flooding shall be securely anchored or elevated to prevent separation of the cryogenic containers and related equipment from foundations or supports.
The area surrounding stationary cryogenic containers shall be provided with a means to prevent accidental discharge of cryogenic fluid from endangering personnel, cryogenic containers, equipment and adjacent structures or to enter enclosed spaces. The stationary cryogenic container shall not be placed where spilled or discharged fluid will be retained around the cryogenic container.
Exception: These drainage requirements shall not apply when it is determined by the commissioner that the cryogenic container does not constitute a hazard, upon consideration of special features such as crushed rock utilized as a heat sink, topographical conditions, nature of occupancy, proximity to structures on the same or adjacent property, and the capacity and construction of cryogenic containers and character of cryogenic fluid to be stored.

Outdoor storage of portable cryogenic containers shall comply with the requirements of FC3203 and this section.
Portable cryogenic containers shall be separated from exposure hazards in accordance with FC Table 3204.3.1.2.1.
FC TABLE 3204.3.1.2.1 SEPARATION OF PORTABLE CRYOGENIC CONTAINERS FROM EXPOSURE HAZARDS
FC TABLE 3204.3.1.2.1 SEPARATION OF PORTABLE CRYOGENIC CONTAINERS FROM EXPOSURE HAZARDS
| EXPOSURE | MINIMUM DISTANCE (feet) |
| Building exits | 10 |
| Building openings other than building exits | 1 |
| Air intakes | 10 |
| Lot lines | 5 |
| Combustible waste or vegetation | 15 |
| Other hazardous materials | In accordance with FC Chapter 27 |
For SI: 1 foot = 304.8 mm
Cryogenic containers shall be placed on surfaces that are compatible with the cryogenic fluid in the cryogenic container.
The area surrounding portable cryogenic containers shall be provided with a means to prevent accidental discharge of fluids from endangering adjacent containers, buildings, equipment or adjoining property.
Exception: These requirements shall not apply when it is determined by the commissioner that the cryogenic container does not constitute a hazard.
Exception: These requirements shall not apply when it is determined by the commissioner that the cryogenic container does not constitute a hazard.
Portable cryogenic containers located in areas subject to flooding shall be properly secured to prevent movement.
Cryogenic containers shall be positioned such that the pressure relief valve discharge is directed away from any building exit.
