It is essential that LPG installations are examined and inspected to ensure their continued safe condition. The minimum requirements for a written scheme of examination and procedures for inspection are set out in the Code.
This major revision of the 1986 edition has been produced in full consultation with the HSE. Separate sections deal with statutory examinations, required under the Pressure Systems Safety Regulations, with other periodic inspections and with routine inspections of installations.

This Code has been prepared by the Liquefied Petroleum Gas Association for the guidance of those involved in the transport by road of LPG in bulk in the UK. It covers the basic requirements for the design, construction, inspection, testing and operation of vehicles, tanks and their ancillary loading and unloading equipment for the carriage by road of pressurised LPG.

This extensive revision of the 1994 edition sets out the basic requirements for the safe carriage by road of LPG in road tankers and tank containers and the specific requirements contained in The Carriage of Dangerous Goods by Road Regulations 1996 and The Carriage of Dangerous Goods (Amendment) Regulations 1998 and 1999. The LPGA Code remains the only authoritative guide.

Covering design, construction, periodic examination, operation and driver training, this Code is essential reading for all in the LPG and road transport industries.

This major revision of the 1995 edition is primarily intended for use by site operator, confronted by fire or the risk of fire, prior to the arrival of the fire service and also to be of assistance to the fire service in tackling incidents involving LPG, where more detailed guidance (for example on-site or off-site emergency plans are under the Control of Major Accident Hazards Regulations [COMAH]) is not available.
The guidance given is not appropriate for use for land use planning or for use in Safety Reports for Upper Tier sites under the COMAH Regulations. It may, however be of assistance in the preparation of Major Accident Prevention Policies (MAPP's) for Lower Tier sites.

This Code of Practice updates the 1998 edition. It contains 6 comprehensive sections and recommends minimum safety standards for the storage of full and nominally empty LPG cylinders and cartridges at depots, stockists, retailers, service station forecourts and all other premises at which they are normally stored or displayed.

The 2004 edition reflects the Dangerous Substances and Explosive Atmospheres Regulations and gives greater guidance on electrical installations in and near cylinder stores.

This extensively revised Code covers Autogas fuel systems for both light and heavy-duty vehicles and is particularly aimed at the aftermarket conversion business. It has been drawn up in consultation with the Department of the Environment, Transport and the Regions and the Vehicle Certification Agency.

The Code sets minimum standards for the safe installation and use of LPG as a motive fuel for road going vehicles. It includes the design and installation of the LPG fuel tank, the fuel feed system (comprising fittings, pipework, connections and controls for the internal combustion engine) and information to be given to the user.

Full account has been taken of advances in technology and of progress towards European and International harmonisation, in particular UN ECE Regulation 67.01 and draft European Standards.

This Code is a guide to safe practice at filling plants dealing with refillable cylinders up to 130 litres water capacity. The filling of automotive cylinders in accordance with Code of Practice No. 20 at consumers' premises, or in similar circumstances, and the filling of aerosols are excluded.

The term 'filling plant' is used to define all process, storage and service areas and buildings associated with filling of LPG cylinders. The transport of cylinders and their stowage on vehicles is excluded. This revision of the 1989 edition reflects detailed changes in operational practices as well as the emergence of relevant European Standards.

BS341 - 'Transportable Gas Container Valves' no longer includes valves for LPG cylinders. These are now specified in this Code of Practice which covers outlet valves for both propane and butane cylinders.

This includes revised drawings for 20mm, 21mm and 27mm clip-on valve connections and withdraws service connection No. 404 which is no longer used. In addition to vapour outlet valve connections, the Code includes outlet valves for liquid withdrawal cylinders. The dimensions shown are those essential for the parts which have to mate with the service connections of LPG equipment.

The air in a new LPG vessel or system has to be removed and replaced by LPG when being put into service. Also, the LPG needs to be discharged and replaced by an inert gas or air when a service vessel or system is taken out of service, or to prepare for internal inspection or repair etc. This work must be undertaken by competent persons and may be subject to certain specific requirements under the Factories Act and the Confined Spaces Regulations.

This revised Code sets out the principles and practices for purging into and out of service and which should form the basis for training of any person carrying out, or supervising this activity.

This revised and updated Code covers the installation of LPG fuel containers and the design and installation of fittings, connections and controls, to provide LPG as a fuel for the propulsion of the craft. This Code covers filling, commissioning, operation and maintenance of the LPG unit, refilling procedures and fuelling facilities.

This major revision of the 1998 edition draws on the experience gained in the intervening years as the Automotive LPG market has grown and on developments in standards for retail petrol forecourts. It covers facilities for refuelling both road vehicles and mechanical handling and maintenance equipment. The Code includes details of the minimum separation distances between various items of plant, design, installation, electrical equipment, fire protection and security, commissioning, operations and inspection and maintenance.

Formerly restricted to checks on flues and ventilation this 1997 edition expands the scope to cover periodic in-service checks on appliances operation and gas soundness. The compact nature of most caravans and other mobile units emphasises the need for regular maintenance and servicing of gas installations. LPG installations in touring caravans and other mobile units put stresses into pipework and appliances not experienced by their static counter parts. This reinforces the need for complete and regular safety checks included in the expanded scope of this code.

This major revision of the 1996 edition has been completely re-structured to make it more easily understood by the majority of users.

It comprises seven comprehensive sections including:

Location and Design; Pipework Materials and Construction of Assemblies; Fabrication and Assembly; Special Requirements for Pipework Below Ground Level (Buried); Pre-service Inspection, Testing and Commissioning; Examination and Modifications/Repairs.

 

GN2 has been revised in the light of practical experience gained from the 1993 and 1996 editions. Opportunity has been taken to clarify the legal situation regarding the Gas Safety (Installation and Use) Regulations 1998 and the need for CORGI registration. Considering the changing profile of heaters in the market place the use of the atmosphere sensing device test rig described in the 1993 and 1996 editions has been reviewed and the decision taken to recommend the replacement of atmosphere sensing devices as there has been no validation of the method on appliances produced in recent years and older appliances should have atmosphere sensing devices changed anyway. Cabinet heaters need regular service in the same way as all fuel burning appliances. Many of the millions of heaters sold in the UK have been in service a long time and now need to be tested and maintained to ensure they continue to be safe.

The Control of Major Accident Hazards Regulations 1999 (COMAH) implement the EC Seveso II Directive. Although there are similarities between COMAH and previous major hazard legislation - the Control of Industrial Major Accident Hazards Regulations 1984 (CIMAH) - COMAH contains many important new requirements.

Lower-tier sites, holding between 50 and 200 tonnes of LPG, must prepare and implement a Major Accident Prevention Policy, which must be available for inspection.

This Guidance Note is intended to assist operators of LPG lower-tier cylinder and bulk storage to meet their obligations in regard to the Major Accident Prevention Policy and its associated Safety Management System.
