The purpose of this standard is to develop industry-wide requirements including methods and procedures for the control of battery room and enclosure environments. This includes adequate ventilation of battery-generated gases, the dissipation of battery-generated head, the control of room and enclosure temperature, the management of battery electrolyte spills, and in general the control of any contaminates within the battery room or enclosure.

Internationally, code officials recognize the need for a modern, up-to-date residential code addressing the design and construction of one- and two-family dwellings and townhouses not more than three stories above grade.

This code provides fundamental safeguards for the generation, installation, storage, piping, use, and handling of hydrogen in compressed gas (GH2) form or cryogenic liquid (LH2) form. Provisions apply to the production, storage, transfer, and use of hydrogen in all occupancies and on all premises.

Help improve industrial safety around compressed gases and cryogenic fluids with the latest edition of NFPA 55, Compressed Gases and Cryogenic Fluids Code.

Working with and around industrial gas calls for a specialized skill set and understanding of general operating and safety requirements. The 2023 edition of NFPA 55, Compressed Gases and Cryogenic Fluids Code, demonstrates how to mitigate physiological, over-pressurization, explosion, and flammability hazards relating to these highly combustible materials in all types of occupancies.

This NFPA® publication is essential for everyone from installers, contractors, and engineers to code enforcers, inspectors, and environmental health and safety personnel. NFPA 55 provides comprehensive coverage of the fundamentals for safer and more effective installation, storage, use, and handling of gases in portable and stationary containers, cylinders, equipment, and tanks.

Code content covers:

• General requirements for emergency readiness and response
• Classification of hazardous materials
• Building control areas and fire and hazard protection systems
• Storage, use, and handling of compressed gases and cryogenic fluids
• Bulk oxygen, gas hydrogen, bulk liquefied hydrogen, gas generation, and carbon dioxide systems
• Storage, handling, and use of ethylene oxide for sterilization and fumigation
• General requirements and special considerations for acetylene cylinder charging plants
• Provisions and maintenance procedures for liquid nitrous oxide systems
• Cryogenic fluid central supply systems in health care facilities 

IEC 60086-2:2015 is applicable to primary batteries based on standardized electrochemical systems. It specifies the physical dimensions, the discharge test conditions and discharge performance requirements. This thirteenth edition cancels and replaces the twelfth edition (2011) and constitutes a technical revision.

Abstract: Specifies requirements for the installation of vented secondary batteries permanently installed in buildings.
Scope:

The purpose of this code is to establish the installation requirements for hydrogen generating equipment, hydrogen utilization equipment, hydrogen dispensing equipment, hydrogen storage containers, hydrogen piping systems and their related accessories.
It applies to all gaseous and liquid hydrogen applications except the following:
- The use of hydrogen in petroleum refineries and chemical plants as feedstock and directly in-process production;
