I. Requirements Analysis

In the face of severe challenges during firefighting and rescue operations, firefighters often confront extreme heat, flames, and exposure to hazardous substances. To safeguard the lives and health of firefighters, high-performance fire-resistant protective clothing has become an indispensable piece of personal protective equipment. This product is designed to address the following core requirements:

1. Ultimate Protection: Withstands direct exposure to high-temperature flames, minimizing harm to firefighters from thermal radiation and heat conduction.

2. Flexible and Comfortable: Ensures wearers can move freely while maintaining protective performance, reducing physical exertion.

3. Durable and Reliable: Materials must possess high strength and durability to withstand complex and unpredictable rescue environments.

4. Easy Maintenance: Simple to clean and maintain, extending its service life.

II. Product Features

1. Superior Flame Retardancy: The outer layer utilizes advanced flame-retardant materials, with burn length strictly controlled at ≤20mm, burn time ≤1s, and smoldering time ≤2s. This effectively prevents fire spread and protects firefighters from direct flame exposure.

2. Superior tear resistance: Outer layer material tear strength ≥100N, ensuring durability during emergency rescue operations and providing long-lasting protection.

3. High-Efficiency Thermal Insulation: The composite material demonstrates exceptional resistance to radiant heat penetration. Under extreme high-temperature conditions (e.g., simulating an 800°C furnace with a 13.6 kW/m² radiant heat source at 23 cm distance), the inner surface temperature rise is controlled to ≤25°C, significantly reducing thermal stress on firefighters.

4. High-Temperature Durability: Exceptional flame resistance with a heat tolerance up to 1300°C. Even within a 1000°C fire environment, it can withstand exposure for 30 seconds while limiting internal surface temperature rise to no more than 25°C, buying firefighters critical rescue time.

5. Comprehensive Heat Resistance Design: The garment incorporates advanced technological materials throughout. Human mannequin testing demonstrates that under simulated fire conditions of 1000°C, the inner surface temperature rise remains ≤13°C after 30 seconds, providing comprehensive protection for firefighters.

III. Application Scenarios

This fire-resistant protective suit is specifically designed for various high-risk fire rescue scenarios, including but not limited to:

1. Petrochemical Fire

2. Forest Fires

3. Industrial Plant Fires

4. Building Fire

5. Vehicle Fire and Explosion Accident Scene

In the aforementioned environments, this product provides firefighters with comprehensive, high-efficiency protection, ensuring their safety during rescue operations.
