The heat insulation fire proximity suit is a special high-grade protective equipment for firefighters to approach ultra-high temperature fire sources and carry out close-range rescue operations, mainly used in extreme high-temperature scenarios such as large-scale fire combustion, high-temperature equipment explosion, furnace fire and thermal radiation intensive fire scenes. Different from conventional fire protective suits focusing on comprehensive basic protection, the proximity suit takes extreme heat insulation and anti-high-temperature radiation as the core performance, enabling firefighters to work stably in high-temperature environments close to fire sources that ordinary protective equipment cannot withstand. It is an essential professional equipment for high-risk close-range fire suppression and emergency disposal.

The suit adopts a multi-layer composite heat insulation structure, composed of external high-temperature radiation reflection layer, middle heat insulation buffer layer and internal breathable protective lining. The outermost aluminum-plated reflection layer can reflect more than 90% of infrared thermal radiation and high-temperature light radiation, fundamentally blocking the massive radiant heat released by high-temperature fire sources. The middle super-thick heat insulation buffer layer uses high-density flame-retardant heat insulation cotton material, which can effectively isolate conductive heat and prevent external high temperature from conducting inward. The internal lining ensures wearing comfort while preventing heat convection, forming a three-dimensional all-round heat insulation protection system.

In terms of performance parameters, the heat insulation fire proximity suit can resist long-term high-temperature radiation of 1000℃ and short-term ultra-high temperature impact of 1300℃, allowing firefighters to approach fire sources within a few meters for fire extinguishing, cooling, equipment disposal and trapped person rescue. At the same time, it retains basic fireproof, anti-scald and anti-splash performance, resisting flame impact and molten slag splashing. The overall design is fitted and flexible, avoiding the bulky and bloated problem of traditional high-temperature protective suits, ensuring that firefighters can complete precise operational actions in high-temperature close-range environments. It provides ultimate safety protection for firefighters engaged in extreme high-temperature fire rescue work.
