Stationary container system certifiers

Stationary tanks and process containers

A stationary container system is a tank or a process container together with its associated pipework and fittings, normally located in one place. The requirements for a stationary tank are more specific than for a process container. Stationary container systems can hold flammable, oxidising, toxic and corrosive substances.

Process containers are stationary containers that hold a hazardous substance during manufacture or use, for example, a mixing container, reaction vessel, distillation column, drier or dip tank.

Stationary tanks include:

  • all parts and materials that help to maintain the structure and integrity of the tanks.

  • any means of closing the tanks, for example, a lid or fitted cover.

  • any component intended to protect the contents of the tank from harm, for example, lightning protection.

  • any other components that are an integral part of the tanks, for example, a liquid height indicator, heating coil, or internal valve.

Stationary tanks do not include packages, intermediate bulk containers (IBC), transportable containers, compressed gas cylinders or tank wagons.

Stationary Container Design and Fabrication Approval

A stationary tank that’s part of a stationary container system must meet certain criteria:

  • The tank must be designed to an approved standard.

  • The design for the tank must be approved by a compliance certifier.

  • The tank must either be built to an approved design by an approved fabricator or treated as a one-off and individually approved.

  • The tank must be installed according to the Health and Safety at Work (Hazardous Substances) Regulations 2017.

  • We conduct comprehensive risk assessments to identify potential hazards associated with the use of stationary containers, including evaluating the impact of hazardous substances, the integrity of the containers, and environmental risks.

  • Our compliance certifiers perform thorough inspections of stationary container systems to verify their integrity and operational safety. If they’re satisfied, they issue certification, confirming that the systems meet safety standards.

    We provide detailed reports documenting our findings, including any identified deficiencies, recommended corrective actions and compliance status.

  • You must have a comprehensive compliance plan for existing stationary container systems that hold up to 60,000 litres, under Regulation 17.91 and Schedule 1 Clause 45 of the Health and Safety at Work (Hazardous Substances) Regulations 2017.

    We can provide a plan that specifies the measures necessary to ensure that your stationary container systems meet current health and safety regulations. This plan will help you effectively manage the risks associated with the storage and handling of hazardous substances, and ensure the safety of your employees, the public and the environment.
