5807.3.3.1 System markings.

Metal hydride hydrogen storage systems shall be marked with the following:

1. Manufacturer's name;

2. Manufacturer's emergency contact information;

3. A unique code or serial number specific to the system;

4. System name or product code that identifies the system by the type of chemistry used in the system;

5. Limitations on refilling of containers that include rated charging pressure and capacity; and

6. Service life indicating the last date the metal hydride hydrogen storage system can be used.

5807.3.3.2 Valve markings.

Metal hydride hydrogen storage system valves shall be marked with the following information:

1. Manufacturer's name;

2. The type of metal hydride hydrogen storage system with which the valve is compatible; and

3. Service life indicating the last date the valve can be used.

5807.3.3.3 Pressure relief device markings.

Metal hydride hydrogen storage system pressure relief devices shall be marked with the following information (markings for pressure relief devices integral to a valve may be made on the valve):

1. Manufacturer's name;

2. The type of metal hydride hydrogen storage system with which the device is compatible; and

3. Activation parameters that include temperature and/or pressure.

5807.3.3.4 Container markings.

Containers used in metal hydride hydrogen storage systems shall be marked with the following information:

1. Manufacturer's name;

2. Standard to which the container was designed and constructed;

3. Date of manufacturer's initial inspection and testing;

4. Individual serial number;

5. The type of metal hydride hydrogen storage system; and

6. Service life identifying the last date the container can be used.

5807.3.4 Physical protection.

Metal hydride hydrogen storage systems installed on powered industrial trucks shall be designed and installed in compliance with the requirements of this section.

5807.3.4.1 Securing containers.

The installation shall be designed to secure containers from movement when the truck is in motion.

5807.3.4.2 Impact protection.

The installation shall be designed to minimize the risk of release of metal hydride or hydrogen gas in the event of a physical impact. System components shall not extend beyond the truck platform or chassis.

5807.4 Operational and maintenance requirements.

Metal hydride hydrogen storage systems shall be operated and maintained in compliance with the requirements of this section.

5807.4.1 Valves.

Container valves shall remain closed except when containers are connected for use and the hydrogen-powered equipment is in use.

5807.4.2 Protection from temperature extremes and falling objects.

Metal hydride hydrogen storage systems shall comply with the requirements of FC 5303.5.4 and 5303.5.5.

5807.4.3 Refilling of containers.

The refilling of metal hydride hydrogen storage system containers with metal hydride shall be in accordance with the listing or approval requirements and manufacturers' instructions. The refilling of metal hydride hydrogen storage systems with hydrogen shall be in accordance with FC 309 and 2309.

5807.4.4 Periodic inspection and testing of containers.

Metal hydride hydrogen storage system containers shall be inspected, tested and requalified for service at least once every 5 years in accordance with the requirements of the United States Department of Transportation.

5807.4.5 Hydrogen purity.

The purity of the hydrogen generated by a metal hydride hydrogen storage system shall meet or exceed the listing or approval requirements, and the design specifications of the truck to be powered by the hydrogen supplied.
