Due to the complex chemical hazard environment, in order to meet the needs of different situations, there are many types of chemical protective clothing, and there are many types of products on the market. The correct choice of chemical protective clothing needs to be selected according to actual needs. The following is an introduction to …

Use maintenance and training content of chemical protective clothing

The protective function of any chemical protective suit is limited, and no chemical protective suit can withstand all chemicals. Good protective clothing can protect as many chemicals as possible. In addition, chemical imitation protective clothing must be used together with other protective equipment to give full play to its protective performance. If people wearing protective …

The effect of heat stress of firefighting suits on the safety and health of firefighters

Heat stress is one of the main factors for firefighters’ injuries. According to statistics, 70% of firefighters’ accidents in the United States are related to heat stress. Heat stress may cause firefighters to have serious consequences such as heat cramps, dehydration, increased burden on the cardiovascular system, nervousness, irritability, and decreased judgment. Therefore, foreign countries …

The type of material and the distribution of the air layer under the clothing have an impact on the thermal protection performance of firefighter clothing

Firefighters often encounter high-temperature disasters such as flames, high-temperature gas or molten metal during fire fighting. Fire-fighting clothing has the function of flame-retardant and heat insulation, which can protect the human body from external high heat and reduce skin burns. For firefighters who work near the fire site for a long time, the heat insulation …

Analysis on the types of fire-retardant fabrics for fire-fighting clothing

As far as the flame-retardant effect of fire-retardant fabrics is concerned, both cotton-nylon flame-retardant fabrics and aramid flame-retardant fabrics have outstanding and superior flame-retardant effects. It should be pointed out that their flame-retardant finishing methods are different. . Cotton and nylon flame-retardant fabrics are mostly used after finishing and flame-retardant, and the washing effect can …

Class A chemical protective clothing is not suitable for all occasions

Chemical protective clothing is divided into different levels according to its protective performance. Take the US Environmental Protection Agency’s classification of protective clothing protection levels as an example, which uses the concept of “A, B, C and D level protection. Class A protective clothing provides the highest level of respiratory, skin and eye protection available. …

The temperature and humidity sensor is integrated in the fire suit

When firefighters perform high-intensity physical tasks in a fire field with high temperature and humidity, the waterproof and thermal insulation material characteristics of firefighting clothing will hinder the heat dissipation of the human body and generate a large amount of physiological heat, which will cause the firefighter’s external environment to become too high and weaken …

Chemical protective clothing may not replace medical protective clothing

In the previous epidemic, there was a shortage of protective equipment for medical staff in many places. Many people can’t help but ask: The chemical protective clothing worn by the chemical defense forces looks very similar to the protective clothing worn by medical staff. Can chemical protective clothing be used instead of medical protective clothing? …

Moisture in the fabric and thermal protection performance of firefighting clothing

Firefighters often come into contact with water whether they control the fire on the periphery or enter the fire scene for rescue. The outer layer of the fire-fighting clothing will inevitably be wetted by water, and part of the moisture will be transferred to the inner layer through the surface of the clothing. At the …

Analysis of Flame Retardant Forms of Flame Retardant Fabrics for Fire Fighting Clothing

At present, fire-retardant fabrics for domestic occupational fire-fighting clothing are mainly divided into permanent fire-retardant fabrics and post-finished fire-retardant fabrics. However, both permanent flame-retardant fabrics and post-finish flame-retardant fabrics of occupational fire-fighting clothing have flame-retardant properties, but there is a big difference between the two. The permanent flame-retardant treatment mainly improves the thermal stability of …
