Refrigeration Installation RAMS Guide for UK Contractors

Key Topics in a Refrigeration Installation RAMS

F-Gas Regulations 2015

All work involving fluorinated greenhouse gases (HFCs, HFOs, PFCs, SF6) — including installation, servicing, leak checking, and recovery — must be carried out by F-Gas certified engineers under Regulation (EU) 517/2014 as retained in UK law. The RAMS must confirm F-Gas certification, identify which refrigerant is in use, and describe containment, leak-check, and recovery procedures.

Refrigerant safety — asphyxiation and OEL

In enclosed plant rooms, refrigerant releases from leaks or pressure testing can displace oxygen and create asphyxiation hazards. Where A2L, A3, or B-class refrigerants are used, the RAMS must assess the room volume, identify atmospheric monitoring requirements, describe emergency ventilation procedures, and confirm that operatives are trained in refrigerant emergency response. Refrigerant gas detectors should be specified for plant rooms.

Pressure testing and pressure systems

Refrigeration systems are pressure systems under PSSR 2000. The RAMS must describe the pressure test procedure (nitrogen pressure test before refrigerant charging), the test pressure, monitoring, and sign-off. A written scheme of examination must be in place before commissioning with refrigerant.

Cold room panel installation

Cold room panel installation presents manual handling risks (panels are heavy and awkward), cutting and drilling hazards, and fire risk if hot works are used near insulation materials. The RAMS must address team handling, cutting equipment controls, and fire safety measures.
