Guidelines for Liquid Chemical Hose Management

(Excludes any applicable taxes)

This publication provides an overview of the hoses used in production, transportation and storage of liquid chemicals, explaining their appropriate use and safe management. Product and service hoses used for water, steam, air and nitrogen are also covered.

This publication includes important safety and operational assessments that must be considered before hoses are chosen. ISO and EN standards outline hose manufacturing specifications and context is given on inherent hazards of application. The book includes maximum working pressure tables and technical diagrams that illustrate features such as flanges and end fittings. The chapter on maintenance and inspection informs readers on condemned hose features.

The purpose of this publication is to provide an overview of the various types of hoses used in the production, transportation and storage of liquid chemicals. It also explains their appropriate use and safe management. While the main focus is on the hoses used for the transfer of chemical products, the essential and frequently used range of service hoses for water, steam, air and nitrogen are also covered.

While this publication may make short references to transfer hoses for oil products, in no way does it set out to challenge the industry standards that exist for the specialist hoses used for oil transfers in the many different operating environments.

Product and service hoses form an integral part of transfer operations, and their choice and use must be based on assessments that cover appropriate use, safety and operational efficiency.


The use of hoses is only recommended where fixed rigid piping is either not suitable or is impractical for the operation taking place.

The range of hoses can vary from those that convey products to those that provide standalone services, or provide services forming part of an integrated product or vapour transfer system. They can be installed on a semi-permanent single or multi-use basis, or be individual hoses that are transferred to the point of use and only connected as and when required.

Depending on the product or service hazards and the location and nature of the application, the risks involved, and the subsequent hose choice, installation, control, use, training and maintenance, will vary. A hose management system with policies and procedures that are based on risk assessments and operability studies should be developed and implemented to ensure the safe and effective use of hoses.

Operational characteristics, including the degree of automation and type of manual tasks conducted, will impact on the policies and procedures that need to be developed and implemented.

To ensure safe and efficient use, procedures need to be implemented for the proper cleaning, inspection, testing and maintenance of the hoses and end fittings. The procedures should include the associated handling and monitoring equipment, such as lifting and support equipment and temperature and pressure gauges.


Product and service hoses may be supplied and/or used by external parties such as road, rail or ship carriers, cleaning contractors or other parties. Appropriate procedures, operational agreements and controls should be in place to ensure that hoses supplied by external parties meet the same standards as those set by the hose management system.

All personnel involved in purchasing, handling, cleaning, testing and maintaining hoses must be suitably trained and experienced in the use of hoses, the risks involved and the controls required.


CDI is managed by a Board of Directors consisting of seven individuals nominated by the participating chemical companies. The Board of Directors establishes policy and is responsible for overall affairs of the foundation. Individual Executive Boards are elected to oversee and direct the staff managing day to day activities for the Marine, Terminals and Marine Packed Cargo Schemes.

CDI Examines Liquid Hose Management Review by Tanker Operator
The Chemical Distribution Institute (CDI) has produced ‘CDI Guidelines for Liquid Chemical Hose Management’, which has been published by Witherby Publishing Group.

The CDI said that while the book’s main focus is on hoses used to transfer chemical products, the essential and frequently used range of service hoses for water, steam, air and nitrogen are also covered.
This guide will form the required publication in the forthcoming eighth edition of CDI Ship Inspection Questionnaire for chemical and LPG carriers, due to be published in the first quarter of next year.
Priced at £75, this 70-page illustrated hardback contains 10 chapters, which gives advice on risk management, inspecting, testing and maintenance, through to emergency response.

This is the first edition of a no doubt long running series on hose management both ashore and afloat.
