typically made up of CO2, FM200 or Novec 1230, and non-liquefied systems are typically Inergen or Nitrogen. Leak sites in the room could mean that the comparted area may not withhold the fire or gaseous extinguishing agent, which has been specifically designed for the space (called design concentration). The likelihood of the gaseous system


effectively extinguishing the fire gets lower and lower as the protected area becomes larger than the size that the extinguishing system was designed for. The technology exists right now to support Door Fan Testing in providing a holistic and thorough integrity test of critical infrastructure.


WHAT IS THE OPINION OF LEADING RESEARCHERS ON COMPARTMENTATION? Leading researchers and scientists agree that the size of the compartments and their relation to fire resistance is key. As well as size, issues in the quality of compartmentation walls can come from maintenance, minor works and refurbishments. Contractors carrying out such tasks can occasionally destroy
