Guidelines for Liquid Chemical Hose Management

(Excludes any applicable taxes)

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, and 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.


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.

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.
