Description

one

This invention relates to clothing that is used to protect a person's body against the effects of open fire when extinguishing fires.

The purpose of the invention is to increase the thermal insulation properties.

Firefighter's protective clothing consists of an outer part made of inorganic fibrous materials and the inner part is made of organic fibrous materials, the outer part of which consists of layers of heat-resistant material that are outer of which is silica fabric, the subsequent layers are in the form of sandwich bags, the layers in each of which is formed by a silica fabric, between these layers is placed mullite-silica fiber material and the inner part is adjacent to three oynomu package layer split leather tanning, chistosherst hydrochloric felt and cotton sateen.

The outer layer of silica fabric is designed to reflect the radiant energy when a firefighter approaches the flame front and protects it while working directly in the flame. Three-layer packages provide enhanced thermal insulation. Leather split is designed to seal pododozhnogo space. Pure wool felt provides absorption of sweating, and cotton satin - absorption and abstraction of sweating.

Suit tailoring is carried out in a known manner. A quartz thread or a combined quartz-metal thread is used to connect the heat-resistant layers of clothing. When joining the parts of the inner layers, sewing threads with high physicomechanical properties are used (heat resistance 450 ° C).

In order to avoid local (local overheating) as a result of the unevenness of heat radiation sources, the suit may be enhanced by an additional layer of non-combustible material with high thermal conductivity (for example, carbon metallized fabric). A heat-conducting non-flammable layer is placed next to the outer layer of heat insulating material or after the first bag. As thermal eye protection

uses three-layer glazing. The two outer layers are made of optically transparent quartz plates of 5 mm each, the third layer is 5 of plexiglas (plexiglass, polystyrene).

To protect against possible mechanical effects, any of the standard and available helmets is used.

To give a fireman stability when working on slippery surfaces (oil and oil pools), the sole of the suit is made of metal studded plates lined with heat-resistant multi-layer materials.

PRI me R 1. Thermal suit TK-1300. The heatproof suit is made in the form of a jumpsuit with a stitched hood and a compartment for placing a breathing apparatus, which is located on the back. The suit is fastened with a zipper and then sealed with two valves, fastened with metal buttons. The hood has a cutout under the viewing glass. The glass is attached to the hood with a frame. The sleeves of the suit are combined, double-sewn, ending with single-fingered mittens. Costume boots are made in one piece with overalls trousers. Thermal protection is achieved through the use of a multi-layer package.

The package of the jumpsuit is as follows: the silica fabric 1 (KT-11-C8 / 3-TO) is metallized; silica fabric II (CT-11-TO); mullite felt MK-200; silica cloth IV (CT-11-E / O, 1-TO); silica fabric II; mullite felt MK-200; silica fabric IV; leather split; pure wool felt; sateen cotton lining.

Example 2. Teplozash: it is a suit with an additional heat-conducting non-flammable layer.

The design of the jumpsuit is similar to Example 1. The jumpsuit package is as follows: the fabric of silica II is metallized; metallized carbon fabric; silica fabric II; mullite felt MK-200; silica fabric IV; silicon fabric 55 earth II; mullite felt MK-200; silica fabric IV; leather split; pure wool felt; sateen lining.
