Protective clothing design principle and safe use
2021-06-27
With the reform and opening up of China's economic construction, the deepening reform of protective clothing is also urgent. How to make the reform of protective clothing meet the requirements of safe production and meet the requirements for workers' safety and health. This paper intends to clarify the direction of protective clothing reform from the classification, design principles and functions of protective clothing.
First, the classification, function and safe use of protective clothing
Protective clothing is divided into general protective clothing and special protective clothing. General protective clothing refers to clothing worn during production labor to prevent dirt, mechanical wear, and anti-twisting. The style includes upper and lower body suits, jumpsuit style, coat type, vest, bib pants, apron, anti-dressing and so on. Generally, the protective clothing has a wide range of fabrics, such as cotton cloth, cotton cloth and blended fabric, and textile fabrics and knitted fabrics are also suitable for production. With the development of China's textile industry, the development of new fibers, new materials with different colors, can be used for general protective clothing fabrics. From the function points, the general protective clothing can be divided into preventing foreign objects from harming the human body, protecting the individual clothes from being stained and protecting the quality of the products or cleaning the work place, such as precision instrument Work Clothes, medical health clothes, scientific research clothes, foods. Health clothes, food service clothes, etc. Special protective clothing refers to all kinds of protective clothing that avoids casualties and reduces occupational hazards in an operating environment that directly endangers workers' safety and health.
The styles of special protective clothing are basically the same as those of general protective clothing, but special protective clothing for certain types of work should include hats, gloves, foot covers, shawls, such as high temperature radiation protective clothing, shielding protective clothing, etc. Fabrics for the production of special protective clothing must meet the requirements of special protective functions. For example, ordinary chemical fiber fabrics cannot be made into antistatic clothing and must contain conductive fibers or wires. However, due to the continuous development of high-tech products, the development of fabrics for special protective clothing has changed with each passing day. For example, steel-making garments with high-temperature radiation have used the pre-furnace protective clothing made of asbestos fibers or white canvas made of asbestos fibers.
General protective clothing and special protective clothing are used or spared during the labor process. Some types of protective clothing, such as anti-drug clothing and family planning drug protective clothing, are only allowed to be used on site. It is strictly forbidden to bring out the workplace to prevent secondary pollution. Interlaced infection.
The safe use of special protective clothing is an effective guarantee for protecting workers' safety and health. The sub-categories are as follows:
1. Fireproof and explosion-proof working places must wear natural fiber protective clothing. Natural fibers do not produce a very hot melt when exposed to fire. And carbonization occurs. In the event of an accident, the injury will be much lighter than wearing chemical protective clothing:
2, anti-static. In workplaces where there is a danger of static electricity, you must wear anti-static clothing, which can reduce the potential of the human body, and also avoid the hazards caused by the potential of the clothing, and pay attention to the replacement of clothes on the spot in places with static electricity;
3. Anti-high temperature radiation. The working environment with high temperature radiation hazard should be worn with flame retardant protective clothing. The development of flame retardant clothing fabric is relatively fast, and the flame retardant eye of the monthly coating process is adopted a few years ago. The flame retardant function has been improved. But the cloth is hard. Suffering from sweat. Rub the skin. Generally do not want to wear. The "Seventh Five-Year" national scientific and technological achievements, Yifang Fenglun, and the development of DuPont's Nomex fiber. Anti-high temperature radiation protective clothing fabrics are ideal, but due to the high price, promotion requires a process:
4. Work in anti-radioactive situations, except for wearing full-body protective clothing. Gloves, aprons and shoe covers are also required to be removed from the field. In order to avoid the second pollution. If found to be contaminated. Need to be tested immediately. Handle with care;
5. Anti-acid and alkaline protective clothing used in the past to be made of coarse wool or rubberized fabric. Still can't avoid acid and alkali splashing on protective clothing. Infiltrate the underwear and hurt the human body. The acid-proof and alkali-resistant fabrics have been successfully developed, and now it is no longer used to make acid-proof and protection for the moon people;
6. Anti-virus protective eye for toxic operations. It is not allowed to wear out the work site at the work site with high concentration of poison gas. A gas mask must be worn when working in a glass box. The sleeves with the two hand holes should be provided with sleeves with elastic cloth to prevent harmful substances from intruding into the body;
7. Protective clothing for dust-proof operation shall be equipped with a hooded jumpsuit. The button shall be covered with a cloth cover, and the wrist and ankle joint shall be fastened to prevent the dust from intruding into the skin. In addition to protective clothing, gloves and protection shall be worn. Glasses, dust masks.
Second, the design principles of protective clothing
The design principle of protective clothing - "safe, applicable, beautiful, generous." The design of protective clothing is designed to be beautiful and generous on the premise of safety and application. Safe and applicable is the basic condition of protective clothing function, and also the basic basis for the use value. Protective clothing must be safe and reliable, meet the needs of labor protection, comfortable to wear, easy to operate, meet the requirements of physiological and ergonomic performance. Beautiful and protective clothing should be of appropriate size, diverse colors, and harmonious working environment, reflecting the spirit of modern workers, stimulating labor enthusiasm and the professional pride of workers. The design principles of safety and application are listed in the national standard of general protective clothing. As a technical regulation, all aspects of scientific research, production, sales and use must follow this principle. Specifically, there are the following aspects:
1. It is beneficial to the normal and long-term health of the human body;
2, the style according to the protection needs to enter. Adapt to physical activity during work. Easy to put on and take off. It is not easy to cause hooks, hangs, twists, and shackles; it is good for preventing dust and dirt from contaminating the body;
3. According to the protection function, select the appropriate fabric;
4. Easy to wash and repair;
5, color should be different from the background of the work, can not affect the correct judgment of various color light signals.
The FR Bibs has the characteristics of wear resistance, temperature resistance, washing resistance, acid and alkali resistance, waterproof and strength. Not only FR Bibs also FR Pants have many large pockets on the clothes, which are easy to carry. There are multiple pockets on the front chest for pens, documents, and other small items. The knees are padded to enhance wear resistance to cushion the pressure on the knees when squatting. The strap is an elastic band and can be adjusted characters. Our company product Flame Retardant Clothing,Inherently Flame Retardant Clothing,FR Bibs and so on uses: Widely used in oil fields, petrochemicals, metallurgy, electric appliances, mechanical processing, electric welding, field fire fighting suits and other heavy-duty clothing or FR Bibs with special requirements for thermal protection.
