FM-Approved Explosion Suppression System: Overview and Maintenance Plan

FM-certified Explosion Suppression System Introduction and Maintenance Plan

• System Introduction

Explosion Suppression System (Explosion Suppression System) () is an active explosion protection device designed to rapidly detect abnormal pressure or flame in the early stage of an explosion (millisecond-level), and release a suppressant (dry powder or clean gas) to suppress flame propagation, control explosion pressure, and prevent escalation of the incident.

FM 5700, according to the 《》 standard, the system should be composed of four core components: detectors, control unit, suppressant storage container, suppressant dispersers; all components must be certified and pass the following key tests:

FM 2. System components (certification requirements)

• Applicable industries

Widely used in environments with deflagration risk such as grain processing, chemical industry, metal dust, battery energy storage (BESS), etc.

• Maintenance plan (according to FM7-17

To ensure long-term effective operation of the system, FM7-17 requires the following periodic maintenance measures:

All maintenance must be performed by FM-certified or manufacturer-authorized technicians, and complete maintenance records must be established and kept for at least three years. The system must be provided with installation, operation, and maintenance manuals to facilitate on-site compliance management.

Shanghai Tengxi Construction Engineering Co., Ltd. can provide selection and design, installation guidance, and annual maintenance services for FM-certified explosion suppression systems, ensuring the equipment meets FM international insurance acceptance requirements and continuous safe operation.
