Description

Fire rescue clothes

Technical Field

The utility model belongs to the technical field of the fire control, concretely relates to fire rescue clothes.

Background

In a high-rise building, firstly, the overload operation of a line is caused to cause a fire; secondly, most of districts are seriously blocked in fire fighting channels, and once a fire accident happens, fire rescue officers and equipment cannot quickly arrive at a fire scene for rescue; thirdly, there are many high floors, and many fire rescue equipment can't satisfy high floor rescue conditions, etc. when fire rescue officers and equipment can't get into the scene of fire relatively fast and accurately, make the intensity of a fire more violent and more difficult to put out, cause great life casualties and property loss.

The existing problem in the current emergency rescue is that in the equipment of the fire-fighting emergency rescue, the fire-fighting personnel can not meet the emergency rescue requirement because the time for fire prevention and heat insulation of protective clothing worn by the firefighter when entering a fire scene to extinguish a malignant fire and the emergency rescue is too short. The national standard GB/T33536-2017 defines the standard parameters of forest fire-protection clothing, and under the condition of resisting flame at 1000 ℃, the forest fire-protection clothing comprises the following components:

1. the flame retardant property of the cloth is as follows: the damage length is less than or equal to 2cm, the smoldering time is less than or equal to 2s, and the afterburning time is less than or equal to 1s;

2. strength performance: the tearing strength between longitude and latitude is more than or equal to 32N;

3. the combined material has the following performance of resisting radiant heat penetration: the temperature rise of the inner surface is less than or equal to 25 ℃;

4. flame resistance: the temperature rise of the inner surface is less than or equal to 25 ℃;

5. the overall heat resistance of the garment is as follows: the temperature rise of the inner surface is less than or equal to 13 ℃;

6. the overall weight of the garment is as follows: less than or equal to 10Kg.

But in fact, in the flame at 1000 ℃, the damage length of the cloth is less than or equal to 2cm, the smoldering time is less than or equal to 2s, and the afterburning time is less than or equal to 1s, so that the time is too short, and the cloth cannot play an effective rescue role under the condition of effectively guaranteeing the life safety of the firemen.

In addition, patent document No. CN2686655 discloses a fire-fighting suit capable of cooling and insulating heat, which is characterized in that a heat-insulating lining is sewn in the existing fire-fighting suit, and cooling ice glue liners are assembled on relevant parts of the lining corresponding to the head, the front chest, the abdomen, the arms, the thighs, the foot surface and the like of a human body, or an inner container matched with clothes, trousers, a hat and boots is arranged in the fire-fighting suit sewn with the heat-insulating lining, and cooling ice glue liners are assembled on the outer layer surface of the inner container suit corresponding to the human body. The fire-fighting suit has the functions of fire prevention and temperature reduction and heat insulation, and can relieve the great influence of high temperature on the body and work of fire fighters. However, the fire-fighting suit still has the following technical problems in practical application:

1. because the condition is very critical when a fire disaster happens, so that the wearing is finished in one minute earlier, the life and more properties can be saved. The ice glue liner needs to be prepared before the firefighter uniform is used, and the ice glue liner needs to be placed in the freezer in advance for refrigeration, so that the wearing procedure is complex, and the practicability is poor.

2. The fire-fighting suit does not strengthen and protect the important parts of the human body, so the safety level of the fire-fighting suit is still lower.

3. This kind of fire-entry suit can not carry if small-size emergency equipment such as fire-extinguishing liquid, therefore lacks interim emergency treatment function in actual rescue, is unfavorable for timely rescue. Meanwhile, the wearing space of the positive pressure respirator is not designed in the firefighter uniform, so that the respiratory reliability of rescuers is not facilitated.

4. The fire-fighting suit has poor puncture resistance and impact resistance due to the reasons of materials, structures and the like.

Based on the technical problems, how to further improve various indexes of the cloth is an important technical problem which needs to be solved urgently at present.
