Protective helmets
   At the production site, in order to prevent accidental falls heavy wounded, accidentally struck his head production, or prevent contamination of harmful substances, workers should wear safety helmets. More protective helmet made of synthetic resin, rubber and the like. Our form of national standards GB2811-81 safety helmet, color, impact resistance, burning, technical performance low temperature, insulation and other special provisions. Depending on the application, a protective helmet simple and modular can be divided into two categories. Simple formula has a general construction workers, coal miners wearing headgear, used to prevent heavy objects fall injured head. Mechanical, chemical and other factories with pollution to cotton or synthetic fibers with tongue cap is also simple formula. Combined mainly welders safety helmets, mine safety dust cap, dust-proof anti-noise helmets.
Anti noise appliances
   Ear: the ear canal or inserted into one kind of plug the external ear canal, commonly used materials for the plastics and rubber. According to the structure and shape the material into a conical plastic earphone, mushroom-shaped plastic earplugs ear mushroom-shaped plastic basket, cylindrical foam earplugs, earplugs and plastically deformable plastic silicone rubber molded earplugs, outsourcing porous plastic sheet microfiber glass wool ear plugs, cotton earplugs. For earplugs requirements: should be different sizes suitable for every man the ear canal configuration, good insulation properties, wear comfortable, easy to wear and remove, and easy to slip, easy to clean and disinfect, no deformation.
   Earmuffs: often rectangular plastic cup bowl, inside with foam or sponge cushion, covering the ears, between the two Beiwan even with flexible headstock moderate grip on the head, adjustable, no tenderness, comfort. It requires its good noise performance, the lower the lower limit resonance rate cap shell, the better the anti-sound effect.
Anti-noise helmet: to cover most of the head, to prevent strong noise of the inner ear by bone conduction, there are two kinds of soft and hard. Soft light weight, small thermal conductivity, acoustic attenuation amount of 24dB, the drawback is not ventilation. Hard plastic hard shell, sound attenuation of up to 30 to 50dB.
Selection tool for preventing noise, you should consider the strength and nature of the operating environment of noise, and a variety of utensils for preventing noise noise attenuation performance. Various anti-noise appliances have a certain scope, should be chosen carefully in accordance with the instructions to use to achieve the best protective effect.
Skin protection products
Mainly refers to the hands and forearms protective gloves and skin contamination paste film.
   (A) Gloves: Protective gloves must be strong enough to ensure that no breakage or cracking during operation. Or stitched leather work gloves is not suitable for use when handling chemicals. In wear, gloves off, make sure that no bare hand contact with the outside workers contaminated gloves.
   (B) protective ointment: in the case of gloves feel impede operations, commonly paste film protective skin contamination. Casein may be protective cream organic solvents, paints and dyes have a good protective effect. Available from the aqueous solution of acid and other polymethylmethacrylate colloidal liquid membrane made of butyl, after the formation of protective film coating, a solvent such as ethyl acetate can be used when only the elution. Protective paste film is not suitable for operation with strong friction.
Composite protective equipment
     For some the body is exposed to harmful factors, especially radioactive material occupations, such as interventional surgeon, many types of interventional procedures, surgeons operating position has also come to change, so any type of intervention the use of protective equipment, there is a certain limitations, which is necessary to wear personal protective equipment as a secondary protective measures.
Personal protective equipment should be designed to meet the safety, lightweight, comfort, convenience principle.
Comfort and convenience
   Comfort depends on two factors: First, the use of soft-type protective material; second, to break down load, several parts of the body is under pressure, and increase the load area, and reduce the pressure.
Such as a monolithic whole proof protective clothing plus a 12cm wide elastic waistband, so that the upper body weight in the shoulder, and the shoulder plus a shoulder structure matches the shape of shoulder pads, shoulder the entire load, reducing stress sense: while commuting decomposition of body weight to bear hip. Split full proof protective clothing, protective vest and skirt by the protective composition, both equipped with belts, more decomposed load characteristics. Protective lead aprons, protective collar fixed, lead helmets, protective caps are used magic button or snap button to make it easy to wear off.
protective suit
   Protective clothing including hats, clothing, pants, aprons, dresses, shoes, cover, etc., to prevent or mitigate thermal radiation, X- rays, microwave radiation and chemical pollution of the body's role. There are the following four:
Heat protective clothing: heat protective clothing should have insulation, fire-retardant, solid performance, but should be breathable, comfortable, easy to wear off; non-regulatory and divided into two kinds of air-conditioning.
Clothing anti-chemical contaminants: Usually there are two types: one is coated with anti-chemical composition of the small permeability or impermeable polymer fabric made of synthetic and natural, and after some padding or waterproof coating additives layer process in order to improve its anti-through capability, such as spraying pesticides personnel protective clothing; the other is polypropylene, polyester and other fabrics production, use to prevent acid. These protective clothing, the state has certain permeability, breathable, water repellent anti-oil, anti-acid and anti-poison through the specific standards.
Microwave shielding clothing: There are two types: ① wire cloth microwave shielding clothes; ② metallized microwave shielding fabric clothing. The barrier coating service has not falling, more soft and comfortable, light weight and other characteristics, is a newer and better one microwave-shielding clothes.
Dust-proof clothing: general use denser cotton, linen or canvas production. It needs to have good air permeability and dust resistance, have a one-piece style and cloned two, cuffs, leg opening shall be fastened with double deduction, the deduction that is sewn on the outside and then Gaibu Jia buckle to prevent dust enter.
