The Fire Industry Association (FIA) guidance note provides a high-level overview of the essential safety practices for dealing with pressurised containers. Given the wide variety of product types and extinguishing agents available on the market, the guidance offers a general framework rather than exhaustive details. Practitioners are encouraged to familiarise themselves with the specific technical requirements and safety features of each product and agent category they encounter in their work.

The document features the importance of several safety features designed to mitigate risks associated with the handling of pressurised containers. These features are critical in ensuring that the containers, when managed appropriately, do not present any significant hazards. Key safety elements include:

Valve Protection Transport Caps and Shrouds:

These devices are essential for protecting the valve from damage during transportation and handling. Depending on the design, these caps or shrouds may need to be removed during the final connection to the agent delivery system.

Anti-Recoil Device:

This outlet plug or cap restricts the flow of agent out of the valve in case of an unintended opening, preventing recoil thrust from causing disruptions to personnel, free-standing containers or other objects in the vicinity.

Overpressure Relief Device:

Typically comprising a burst disc and an associated anti-recoil fitting, this device ensures a controlled slow release of the contents in the event of over-pressurisation, thereby preventing container rupture during fire or overheating conditions.

Purpose-Built Restraining Bracketry or Other Means:

This involves racking systems designed to securely hold the containers, preventing mechanical disruptions and movements caused by reaction forces from intended or unintended content releases.

Ensuring Safety and Compliance

The pressurised containers used in fixed firefighting systems are designed and validated according to prevailing codes, making them safe for use when handled correctly. This guidance note serves as a vital resource for practitioners, reinforcing the importance of adhering to best practices to maintain safety standards.

The FIA’s new guidance note is an invaluable tool for anyone involved in the handling of pressurised container assemblies within fixed firefighting systems. By providing a broad overview of industry best practices, it helps ensure that safety remains a top priority across all stages of handling these crucial components.
