BS ISO 16924:2016 pdf download.Natural gas fuelling stations — LNG stations for fuelling vehicles
1 Scope
This document specifies the design, construction, operation, maintenance and inspection of stations for fuelling liquefied natural gas (LNG) to vehicles, including equipment, safety and control devices. This document also specifies the design, construction, operation, maintenance and inspection of fuelling stations for using LNG as an onsite source for fuelling CNG to vehicles (LCNG fuelling stations), including safety and control devices of the station and specific LCNG fuelling station equipment. NOTE Specific CNG equipment is dealt with in ISO 16923. This document is applicable to fuelling stations receiving LNG and other liquefied methane-rich gases that comply with local applicable gas composition regulation or with the gas quality requirements of ISO 13686. This document includes all equipment from the LNG storage tank filling connection up to the fuelling nozzle on the vehicle. The LNG storage tank filling connection itself and the vehicle fuelling nozzle are not covered in this document.
This document includes fuelling stations having the following characteristics:
— private access;
— public access (self-service or assisted);
— metered dispensing and non metered dispensing;
— fuelling stations with fixed LNG storage;
— fuelling stations with mobile LNG storage;
— movable fuelling stations;
— mobile fuelling stations;
— multi-fuel stations.

5.1.1 General
Risks shall be managed throughout the life cycle of the LNG fuelling station through the adoption of a risk management policy and framework that systematically identifies, analyses and evaluates the risks to personnel, the environment and equipment. The principles and guidelines of ISO 12100, ISO 31000 and IEC 31010 shall be followed in developing a risk management policy and a risk management framework. One or more of the risk assessment techniques described in IEC 31010 shall be used to conduct risk assessments. Appropriate risk mitigation measures can then be identified and implemented to reduce the risks to as low as reasonably practicable. Risk mitigation can be achieved through various measures to reduction of the probability and/or the consequences of a risk scenario.
