What are stationary container systems?
A stationary container system is a fixed tank or a process container and its associated pipe works and fittings. The requirements for a stationary tank are more specific than for a process container.
Stationary container systems can hold flammable, oxidising, toxic, corrosive and ecotoxic substances.
A stationary tank is used for storing or supplying hazardous substances; and is normally located at a specific
place. It includes:
all parts and materials (for example, coatings) that help to maintain the structure and integrity of the tank
any means of closing the tank (for example, a lid or
any component of the tank intended to protect the
contents of the tank from harm (for example, lightning protection) and
any other component that is an integral part of the
tank (for example, a liquid height indicator, heating coil, or internal valve).
A stationary tank does not include packaging, intermediate bulk containers (IBC), portable tanks and mulitiple-element gas containers or compressed gas cylinders.
A process container is a stationary container that
contains a hazardous substance in the course of manufacture or use, for example,
a mixing container, reaction vessel, distillation column, drier, or dip
