FM Standards for Explosion Protection in Semiconductor Facilities: Explosion Venting, Blast Resistance, and Safe Storage Arrangements

FM Standard Explosion Protection for Semiconductor Facilities: Integrated Venting, Blast Resistance and Safe Storage Solutions

Providing comprehensive FM-compliant risk control for high-tech plants In semiconductor, display panel, photovoltaic and other high-tech plants, large quantities of flammable and explosive chemicals and high-energy processes make explosion risk ever-present. If protection is inadequate, accidental explosions will cause equipment damage, production interruptions, and even casualties, resulting in incalculable losses.

FM and other international insurance bodies have strict standard requirements for such risks, and plant designers and safety managers must strengthen explosion protection measures at the source to meet FM standards and satisfy insurance and regulatory requirements. This not only concerns safety, but directly affects operational continuity and asset protection.

Venting protection: rapidly release pressure to prevent structural failure Explosion venting (pressure relief) is a key measure to prevent structural failure caused by sudden pressure rise in enclosed spaces. According to FM Data Sheet 1-44 and other standards, exterior walls and roofs of buildings should be designed as "pressure relief surfaces" that preferentially rupture in the event of deflagration, directing the blast wave outdoors. To achieve this, our solution uses FM-certified vent panel assemblies, including:

• Automatically opening venting windows, thin wall or roof panels
• Core vent fasteners and tethering cable systems

When internal pressure in the plant exceeds a set threshold, these pressure relief surfaces instantaneously open, quickly discharging hot, high-pressure gases to minimize impact on the main structure. At the same time, the vent fasteners are designed to fracture and release under overpressure, while the tethering cables secure the vent panels to prevent panels from detaching and causing injury.

This series of precisely engineered and rigorously tested venting solutions ensures timely and effective pressure release at the first moment of an explosion, protecting personnel safety and the integrity of the building.

Blast-resistant design: reinforce structure to minimize impact While the venting mechanism directs the primary pressure outward, the structures in critical areas must themselves possess blast resistance. According to FM principles for blast-resistant buildings, blast-resistant partition walls should be placed between high-risk zones and key production areas to withstand residual blast pressures without collapsing.

This solution introduces a proprietary, high-performance fireproof and blast-resistant panel for constructing blast walls and reinforcing structures in the plant. The panel consists of a high-strength perforated steel plate and fiber-reinforced cement bonded together through a high-pressure process into a single unit, capable of absorbing and dissipating blast impact energy to minimize damage to the building.

Testing shows

• Its structural strength is sufficient to withstand deflagration impacts that may occur in semiconductor plants
• It also exhibits excellent fire resistance, passing a 4-hour fire endurance test

This means that in the event of a sudden fire or explosion, blast walls can block flames and high temperatures, prevent cascading disasters, and buy precious time for personnel evacuation and firefighting. By organically combining venting and blast-resistant design, the plant forms a dual internal and external defense: external pressure-relief buffering and internal robust barriers, comprehensively protecting critical production areas.

Safe storage: isolate flammables to reduce risk at the source High-tech manufacturing relies on large amounts of chemical solvents, gases and other hazardous materials, so safe storage is an indispensable part of an explosion protection system. FM recommends storing flammable and explosive materials in separate buildings or areas remote from the main plant to reduce threats to the primary facility.

• Our hazardous materials safe storage solution is a modular storage unit that complies with FM certification standards, equivalent to an outdoor standalone explosion-proof storage building. The unit is designed with fireproof and explosion-proof structure, equipped with vent panels and a ventilation system, and can actively release explosion pressure and block flame spread if an incident occurs internally.

• Additionally, its base is fitted with a leak-proof collection sump to prevent secondary hazards from chemical spills. By placing large quantities of flammable chemicals in safe storage units located outside the plant area, the explosion risk to the main plant is greatly reduced; even if an incident occurs inside a storage unit, the robust explosion-proof enclosure and pressure-relief devices can confine the impact locally and prevent it from affecting core production areas.

Such designs meet regulatory and insurance requirements and demonstrate responsibility for surrounding personnel and the environment, truly achieving safe isolation of hazard sources.
