Publications

All duties required under Seveso II are maintained in Seveso 3, and some additional duties are added. In each document section, the “Seveso 3 additional duties”, which are significant for the gas industry, are described in this blue italic text.

This publication provides the minimum requirements and the practices for design, construction, installation, operation, and maintenance of refrigerated liquefied carbon dioxide (CO2) storage at users’ premises

This publication addresses the operation of the reboilers of air separation plants. It contains a summary of current knowledge and industrial practices used in their safe application. It specifically applies to the main reboiler and oxygen product reboilers in which the oxygen concentration is greater than 75% in the liquid phase. Its guiding principles may be used for other reboilers within air separation plants, including auxiliary vaporizers, guard adsorber vaporizers, argon condensers, and the main reboilers in nitrogen generators. Reboilers that are used in conjunction with krypton/xenon production are typically operated with higher hydrocarbon limits than typical air separation unit (ASU) reboilers. The allowable levels of hydrocarbons as well as additional safeguards for the bath-type reboilers used in these systems are listed in Appendix A.

HyCO facilities are not specifically included because the typical site inventory is not sufficient to be included in Seveso. The legal duties for HyCO sites which do come into scope are in principle the same.

Typical facilities include air separation plants, acetylene production plants, cylinder transfilling plants and/or cylinder re-distribution facilities, where they have sufficient inventory of dangerous substances.

This publication provides guidance to help prevent and detect internal corrosion of compressed gas cylinders and tubes.

Subsequent requirements are designed to implement this objective and/or to assist the site operator to demonstrate their compliance to the satisfaction of the relevant Competent Authority.

This publication gives recommendations for both the purchase of new aluminium alloy cylinders and the manner for treating certain cylinders manufactured from specific alloys already in service.

Refrigerated liquified carbon dioxide has specific physical properties that present additional handling risks as compared to other cryogenic gases. This publication focuses on these risks and gives guidance on how they can be handled. This publication contains information and guidance for transport function personnel dealing with carbon dioxide. For further information on transport safety, refer to EIGA Info TS01 Transport Safety Information, an Overview.

This publication covers load securing of individual gas cylinders, bundles, pallets of gas cylinders, pressure drums, cryogenic receptacles and small tank containers which are not permanently connected to the vehicle. It is concerned with product carrying equipment which has to be off-loaded for filling or withdrawal.
