1. Disposable protective clothing must be inspected and air pressure tested to ensure that there are no defects. In addition, protective clothing must be selected according to its use. 2. However, it is necessary to apply antifogging agent inside the sight glass of protective clothing according to the recommended instructions. 3. Choose two people as "cooperative organization", that is, another person helps when wearing protective clothing. 4. Underwear should be worn under protective clothing. At least, it is recommended to wear long sleeves and trousers, or long "underwear". Fire resistant underwear should be considered. 5.

Take off your shoes (this step can be omitted when wearing a protective suit with long rubber boots). Some rubber boots are not allowed to be worn outdoors. According to the protection function, it can be divided into health type protective clothing, such as radiation protection clothing, cold protection clothing, heat insulation clothing and antibacterial clothing; and safety type protective clothing, protective clothing, protective clothing Protective clothing, such as flame retardant clothing, flame retardant protective clothing, arc protective clothing, anti-static clothing, bullet proof clothing, stab proof clothing, aerospace suit, diving suit, acid proof clothing and insect proof clothing, etc.; work clothes to keep the wearer clean, such as oil proof clothing, dust-proof clothing and water repellent clothing. The structure of protective clothing has the characteristics of anti permeability, good air permeability, high strength and high hydrostatic pressure resistance. It should be mainly used in industrial, electronic, medical, chemical and bacterial infection prevention environments In addition to meeting the wear requirements of high strength and high wear resistance, they are often different due to different protection purposes and protection principles, ranging from natural materials such as cotton, wool, silk, lead, synthetic materials such as rubber, plastic, resin, synthetic fiber, etc., to modern new functional materials and composite materials, such as impact resistant para aromatic polyamide and high strength and high modulus polyethylene fiber products, oil repellent fluorination They are complex, radiation-resistant polyimide fiber, antistatic agglomerated acrylic fiber, copper complex fiber, antibacterial fiber and related odor resistant finished fabric.
