Firefighters fire protection clothing is firefighters into the fire, a short time through the fire zone or a short period of time in the flame zone for Fire fighting

Protective clothing worn to protect itself from the damage of flames and strong radiant heat during emergency rescue;

Firefighters fire protection clothing using a split structure, the hood, with a ventilator backpack protective top, protective trousers, protective gloves and boots, such as five parts.

Principle and function characteristics

The eight-layer fabric structure with low thermal conductivity, excellent thermal insulation and high temperature and hot steam resistance can be used to resist the attack of strong radiant heat, conduction heat and high thermal steam.

The first to second floor is a high temperature resistant fireproof layer.

The third to fourth floor is refractory insulating layer.

The fifth floor is a waterproof reflector layer.

The sixth to seventh floor is a flame-retardant insulating layer.

The eighth floor is the comfort layer.

Technical Performance Parameters:

Flame retardant properties of outer fabrics

The combustion time is not greater than 05, the smoldering time is not greater than 0.9s, the damage length is not less than 10mm

The outer fabric rips strong

Tearing strong warp to >96n, weft >58n

Anti-Radiant thermal permeability of whole composite layer fabric

After 13.6kw/m? radiation heat flux irradiation 120s, the inner surface heats up no more than 14°c

Anti-flame combustion performance of holistic combination level

After burning 30s on a temperature of 1000t flame, the inner surface temperature rise does not exceed °c

Overall thermal resistance

Human model dress in the simulated fire temperature 1000°c conditions, 30s after the human model of the surface temperature rise does not exceed 13°c.
