Stopford have featured again in this quarter’s Tank Storage Association newsletter issued today. This went out to 22 companies operating ~300 terminals in the UK and ROI. Stopford’s article focused on recent changes to DSEAR legislation for corrosives and gases under pressure. Below is our article or follow this link to the full newsletter.

Are you affected? DSEAR Legislation Changes – Corrosives & Gases under pressure
The DSEAR Regulations have been part of the UK’s Health and Safety Legislation for almost 20 years. Originally intended to reduce risks of explosion, they have been extended to cover other dangerous substances, including corrosive chemicals. This article looks at these changes and how they could affect TSA members.
The DSEAR Regulations were introduced in 2002 to implement the European ATEX Directive and have become a major element of the UK’s Health and Safety legislation. Their original intention was to reduce risks of “dangerous substances” causing fires and explosions.
However, since June 2015, DSEAR has been extended to cover other dangerous substances – gases under pressure and corrosive chemicals. The regulations now need to consider the risks posed by the corrosive nature of the chemicals handled, their potential to react with other chemicals on site and the potential for harm related to their storage pressure.
Substances which now must be addressed include chemicals such as caustic and acids, as well as gases under pressure. This extension to the legislation means that, for the first time, many tank storage sites will have obligations under DSEAR.
For flammable materials such as petrol and diesel DSEAR risk assessments are well developed and accepted by industry. The site must identify potential release points, define zones where explosive atmospheres may occur and then eliminate sources of ignition. When applied to gases under pressure or corrosive chemicals, an alternative approach is required. Stopford have undertaken these assessments using a combination of asset integrity and good practice for handling and storage of these materials.
Stopford Case Study
One example of the successful application of the Stopford methodology has been in the water industry.
Stopford have applied this methodology for the bulk storage of Sulphuric and Phosphoric acids, Sodium Hydroxide, Sodium Hypochlorite, etc. In addition, assessments have also been carried out for Chlorine and Oxygen gases are stored in bulk under pressure.
Experienced Stopford personnel carried out comprehensive site surveys, using non-invasive techniques to review storage, pumping and conveying systems. The study focused on the suitability of materials used, potential for loss of containment, protective systems to prevent tank overflows, controls on tank filling, pressure control and pressure relief systems, adequacy of emergency procedures and management controls.
