Overview

Hydrogen vehical fueling station

This standard was developed after the hydrogen gas industry demonstrated the need for safety guidelines for breakaway devices used for dispensing hoses and systems. ANSI/CSA HGV 4.4-2013 - Breakaway Devices for Compressed Hydrogen Dispensing Hoses and Systems establishes performance-based requirements for safe operations, substantial & durable construction, and performance testing of fueling hose breakaway devices for use in hydrogen gas fueling applications.

Highlights of ANSI/CSA HGV 4.4-2013 Include:

When a vehicle drives off with the nozzle attached to the vehicle’s fueling receptacle, devices covered under this standard should:

  • Minimize the escape of gaseous hydrogen by automatically shutting off the flow of gas from the dispenser and controlling the depressurization of the hose
  • Minimize damage to the vehicle and dispenser
