What are the classifications of protective safety work clothing
In modern industrial working environments, workers often encounter flames, high temperatures, molten metals, corrosive chemicals, low temperatures, mechanical processing, and some special hazards. For these hazards, specialized protective clothing is required to protect the entire body. Also known as safety work clothing, it is divided into special safety work clothing and general safety work clothing. For general work, cotton or synthetic fiber fabrics are used, suitable for use in general workplaces without special requirements.
Special safety work clothing include dust and gas resistant clothing, chemical pollution resistant clothing, heat resistant and fire-resistant clothing, radiation resistant clothing, and anti-static clothing according to the needs of the working environment.
1、 Dust and gas resistant clothing
Dust and gas resistant suits are all full body protective safety work clothing.
1. Dust proof clothing
Suitable for dust operations, it generally consists of a hood or headscarf from head to shoulder, upper and lower clothing, with tight cuffs, pants, and hem. It is made of breathable fabric with a dense texture and smooth surface.
2. Antivirus clothing
There are two types of gas protective clothing: airtight and breathable. Closed type is a type of breathable protective clothing made of impermeable materials, consisting of a hood and clothes connected from top to bottom. The overall structure is sealed, and clean air is fed in from the top of the head and discharged through exhaust valves set at cuffs, pants, and other parts. The clothing maintains a certain positive pressure inside, forming a comfortable microclimate for the wearer. Aerated protective clothing can effectively prevent the harm of toxic gas and dust, and is suitable for places with severe pollution hazards. Made of special breathable fabrics such as breathable anti-virus clothing fibers and activated carbon. Tightly tied cuffs and cuffs can defend against the hazards of certain toxic gases and smoke, making it suitable for wearing in lightly polluted areas.
2、 Chemical pollution prevention clothing
There are various types, materials, and uses of chemical pollution resistant clothing, including acid and alkali resistant clothing, oil resistant clothing, etc.
1. Rubber acid and alkali resistant clothing
Rubber is acid and alkali resistant and has a rubber content greater than 60%. It is made of rubber cloth with stabilizers added during refining, and the material is not breathable. The styles include safety work clothing, suspenders, reverse dressing, aprons, sleeves, etc. It is suitable for preventing strong acid and alkali corrosion; Anti acid and alkali splashing operations.
2. Plastic safety work clothing
Plastic work is made of polyvinyl chloride film and is not breathable. The styles include safety work clothing, reverse dressing, aprons, etc. It is suitable for operations that are resistant to mild acid and alkali corrosion, waterproof, oil resistant, and low concentration toxins, and is not resistant to high temperatures and solvents.
3. Acid resistant silk safety work clothing
Acid resistant silk safety work clothing are made of chemically treated tussah silk and synthetic fiber fabrics, with breathable materials. The styles include safety work clothing, coats, etc. It is suitable for operations that prevent acid mist corrosion, with good acid resistance and breathability, and a certain degree of alkali and oil resistance.
4. Synthetic fiber safety work clothing
Synthetic fiber safety work clothing are made of synthetic fiber fabrics such as polyester, polypropylene, and chloroprene, with styles such as safety work clothing and coats. It is suitable for low concentration acid-base corrosion prevention operations and has poor permeability.
5. Woolen acid resistant clothing
Wool cloth is acid resistant and made of raw wool. The material has good breathability and is suitable for preventing the corrosion of low concentration acid mist. It has the ability to adsorb and penetrate acid, and has insulation and cold resistance.
6. Oil proof safety work clothing
Oil resistant safety work clothing are made of vulcanized synthetic rubber, polyurethane cloth, and fluorinated resin fibers, which have both oil and water resistant properties. Synthetic rubber oil resistant clothing can resist organic solvents, while polyurethane oil resistant clothing can also resist organic deep agents. The styles include safety work clothing, suspenders, aprons, sleeves, etc.
3、 Heat and fire resistant safety work clothing
Heat resistant safety work clothing are suitable for workplaces with high temperature, high heat, and strong radiation heat. The materials used for making heat resistant safety work clothing should have high radiation blocking efficiency, low thermal conductivity, flame retardancy, and high surface reflectivity. It is made of materials such as canvas, asbestos, and aluminum film. White canvas is made of cotton and linen canvas woven from natural plant fibers to prevent heat. It has the characteristics of insulation, splashing sparks, and easy falling of molten materials, wear resistance, high tensile strength, and good breathability. Asbestos heat resistant clothing is made of asbestos cloth containing a small amount of cotton fiber, which has a strong shielding effect on radiant heat. However, asbestos is harmful to the human body and should be careful not to inhale it when used. Workers working on molten metal often use asbestos leg protectors and aprons. Aluminum film heat resistant clothing is made of aluminum plated or aluminized fibers on the substrate, suitable for extremely high temperature operations such as furnace repair and fire rescue. The aluminum film is silver white with high reflectivity, and the lining serves as insulation. It is resistant to aging and fire, but has poor breathability.
4、 Other special safety work clothing
1. Anti clogging clothing
Cold clothing has good insulation, low thermal conductivity, and high heat absorption efficiency on the outer surface. It is generally filled with natural plants, animal fur, down, or synthetic fibers. Ordinary cotton and leather winter jackets have good insulation performance, while chemical fiber winter jackets are lightweight and popular among outdoor workers.
2. Waterproof clothing
Waterproof clothing is made of adhesive tape raincoats, cut from waterproof tape and bonded with neoprene adhesive. It is divided into single and double sided adhesive, including raincoats, ponchos, etc. Suitable for working with spray water and rainy days; Underwater jackets are suitable for wading operations such as sewers, culverts, and aquatic fishing
