FIA has just published a new guide that reviews best practice and the Standards underpinning contemporary fire detection systems for use in high airflow environments, including those used to automatically activate fixed gaseous fire extinguishing systems. It focuses on UK practice, identifying relevant codes, and describing how they are used to achieve effective detection systems in these challenging environments. The document does not consider special hazards with liquid fuel fires and fast flaming fires which may not have a significant and detectable incipient stage. The document considers detection in high airflow used for equipment cooling with a focus on electronic equipment. However, the principles are applicable to other forced ventilated situations and may be relevant to free or naturally ventilated conditions.
