Small hydrogen plants used in, for example, fuelling applications have a low environmental impact due to size and technology employed. Over regulation of these plants is a barrier to the development of hydrogen as an energy carrier. On-site hydrogen production is also expected to be required in relation to road vehicle refuelling. This publication is on the environmental impacts and operational controls for these packaged hydrogen plants and is intended to be used as guidance for permitting these plants so that simpler permitting can be applied.

This publication addresses validation for ASU cryogenic manufacturing and cargo transport unit filling processes relating to medical oxygen and medical nitrogen meeting the requirements of the European monographs

Guide that describes basic test requirements the VIPR manufacturer should perform and the performance checks carried out by the gas manufacturer, ensuring the VIPR performs as intended throughout its service life

This publication addresses vacuum-jacketed piping used in any stationary industrial gases applications including air separation plants, other industrial gases facilities, and customer installations in liquid oxygen service. This publication provides guidance to those persons directly associated with the design, installation, operation, and maintenance of vacuum-jacketed piping systems used to transfer liquid oxygen.

From the information given in this report and a risk assessment, the view of the EIGA companies is that the levels of elemental impurities within the lincensed medicinal gases that they supply for patient treatment are well below the limits set out in ICH Q3D

This publication applies to HYCO plants. Information in this publication may also be applied to facilities, such as trailer fill stations, cylinder fill stations, electrolytic production facilities, or vehicle fuelling stations. This publication covers methodologies for prevention of, detection of, and response to flammable and/or toxic gas leaks that occur within the fence line of these facilities.

This publication explains the historical background to the formulae used to calculate the minimum design wall thickness of seamless steel and aluminium alloy cylinders and the differences between them. The publication is based on Technical Information TI 002, Development of calculation formulas for cylinder wall thickness prepared by the European Cylinder Makers Association, ECMA.

This publication explains the historical background of the pressure test methods used during the manufacture of high pressure seamless aluminium alloy and seamless steel cylinders. The publication is based on Technical Information TI 001, Description of the pressure test methods used during cylinder manufacture, prepared by the European Cylinder Makers Association, ECMA.

This publication provides guidance for the design and the safe operations of acetylene customers’ installations. This publication details the best available current practices for the design of acetylene fixed and mobile supply systems. The publication also includes recommendations for the maintenance and operations of the equipment that are part of these installations.

The purpose of this publication is to provide recommendations and a methodology for the safe design of venting systems for hydrogen installations and equipment located at a customer site. The design of a hydrogen vent system aims at preventing Deflagration to Detonation Transition (DDT) and mitigating the hazards from fires, deflagration and DDT if it occures. The following scenarios are reflected: • deflagration due to the delayed ignition of the explosive hydrogen/air mixture coming out of the vent stack; • thermal radiation generated by the jet fire (the flame coming out of the vent stack); and • DDT inside the vent system due to the acceleration of the combustion of the air/hydrogen mixture that can be present inside the venting system (in the presence of an ignition source). This hazard is relevant if air can enter the venting system.
