Safety Protocols for Hydrogen Storage
Outdoor Storage
- Distance from Structures: Hydrogen should be stored outside at a safe distance from structures, ventilation intakes, and vehicle routes. The separation distance depends on storage volume, pressure, and pipe diameter. Refer to NFPA 2 for specific guidelines.
- Weather Protection: If cylinders are stored outdoors with weather protection, ensure the structure is noncombustible and well-ventilated.
Indoor Use and Storage
- Ventilation and Construction: Buildings should use noncombustible materials. Mechanical ventilation systems should introduce air low to the floor and exhaust at the highest point of the room. Ensure ventilation for both normal and emergency conditions.
- Hydrogen Sensors: Install hydrogen sensors to detect gas accumulation.
- Ignition Source Control: Eliminate ignition sources by using classified electrical equipment.
- Electrical Bonding: Ensure all hydrogen system components are electrically bonded and grounded.
General Safety Considerations
- Cylinder Handling: Store cylinders upright and secure them to prevent tipping. Keep them away from heat sources and direct sunlight.
- Approved Equipment: Only use materials and equipment designed for hydrogen applications to avoid leaks and ignition sources.
- Leak Detection: Implement advanced hydrogen leakage detection systems such as gas sensors and thermal imaging.
- Training and Awareness: Educate personnel on handling procedures, emergency response, and safety protocols.
- Static Prevention: Implement grounding and bonding techniques to prevent static discharge.
Testing and Maintenance
- Proof Pressure Test: Conduct regular proof pressure tests by pressurizing containers to 150% of the nominal working pressure to verify their strength.
- Regular Inspections: Perform regular inspections of storage facilities and equipment to ensure they remain in good condition.
By adhering to these safety protocols, the risks associated with hydrogen storage can be mitigated effectively.
