一、类型和面料的选择：根据面料的不同，防酸工作服可分为不透气型和透气型两类。接触强酸作业等严重酸污染场所人员适宜选用不透气型防酸工作服，其面料一般采用单面、双面橡胶涂覆织物(胶布)、聚乙烯塑料薄膜(主要做围裙、套袖等)等，由于面料本身特性不能很好地完成身体和外界环境之间的温湿度交换，所以在服装结构上可有不影响防护性能的透气设计，以弥补面料的不足;防酸雾、酸性气体腐蚀等中、轻度酸污染场所适宜选用透气型防酸工作服，其透气性好、穿着舒适、柔软轻便，面料一般采用耐酸纤维织物，如粗毛呢、柞蚕丝、氯纶、涤纶等，氯纶、涤纶等合成纤维虽然不耐高温、吸湿率低、对有机溶剂稳定性差，但耐酸稳定性优于粗毛呢、柞蚕丝等天然纤维织物，尤其是涤纶还对一般的有机溶剂有较好的稳定性，目前被广泛选用。
A type, and the choice of fabric: fabric according to different national standard can be divided into two types, breathable and breathable. People who have contact with strong acid and other serious acid pollution places are suitable for the use of air tight acid proof suit. The fabric usually uses one side, double-sided rubber coated fabric (rubber cloth), polyethylene plastic film (mainly apron, sleeve etc.), etc. because the fabric itself can not complete the temperature and humidity between the body and the outside environment well. Change, so in the clothing structure can have a breathable design that does not affect the protective performance, to make up for the shortage of fabric; acid fog, acid gas corrosion and other medium and mild acid pollution places suitable for the use of air permeable type anti acid work clothes, it has good air permeability, comfortable, soft and portable fabric, such as coarse wool fabric, such as coarse wool. The synthetic fibers, such as tussah silk, fiber, polyester fiber, etc., are not resistant to high temperature, low moisture absorption and poor stability of organic solvents, but the stability of acid resistance is better than that of coarse wool and tussah silk. Especially, polyester fiber has good stability to the general organic solvent and is widely used at present.

二、防酸级别的选择：按耐酸程度由高到低，透气型防酸工作服分为一级、二级、三级三个等级，不透气型防酸工作服分为一级、二级两个等级。选择防酸服时应对工作环境进行相关的危险性分析，及对人体健康有何危害，它们的浓度如何，以何种形态(液态、气态)出现，作业人员可能以何种方式(持续、偶然)与此类危险品接触，再根据针对不同工种、不同作业场所酸危害程度的分析，综合考虑防护性、耐用性，兼顾舒适性和成本因素，确定防酸服的种类(透气型、不透气型)及防酸级别(一级、二级、三级)，选择适当防酸级别的防酸服。

Two, the selection of acid prevention level: according to the acid tolerance from high to low, air permeable acid anti acid work clothes are divided into first class, two grade and three grade three grades, and the air permeable type anti acid work clothes are divided into first class and two grade two grades. When choosing an acid proof suit, the risk analysis of the working environment and the harm to the health of the human body, how the concentration and the form (liquid and gaseous) appear, how the operator may be exposed to such dangerous products (continuous and accidental), and then according to the acid danger of different types of work and different workplace. The analysis of damage degree, comprehensive consideration of protection, durability, comfort and cost factors, determine the type of acid proof clothing (breathable, impermeable type) and acid level (grade 1, two, three), and choose the proper acid proof suit.

三、款式的选择：防酸工作服的款式有分身式、大褂式、连体式及围裙套袖等。分身式防酸工作服包括上衣和裤子。上衣要求领口紧、袖口紧、下摆紧，裤子为直筒式;大褂式防酸工作服翻领和立领两用，要求后背下部无开缝;连体式防酸工作服指上衣与裤子形成一体，要求领口紧、袖口紧和裤脚紧。对于防酸服而言，安全概念不仅指防护功能，而且款式结构在工作过程中也应符合安全要求。
Three, the choice of styles: national standard styles have split type, coat type, Siamese style and aprons sleeve etc.. One type of acid proof coverall includes a jacket and trousers. The jacket requires tight neckline, tight cuffs and tightness, trousers are straight tube, and gown type anti acid working clothes and collar are used for double use, and there is no slit on the back of the back; the joint type anti acid work clothing is a combination of jacket and trousers, which requires tight neckline, tight cuffs and tight trouser feet. For acid proof clothing, the concept of safety is not only about the protection function, but also the style and structure should meet the safety requirements in the process of work.

选用时应按照身体接触酸液的部位选择不同款式的防酸工作服，注意防酸工作服一般不应有明袋，以免积存飞溅的酸液。可选择分身式和大褂式，其缝制技术直接影响了产品的防酸渗透性能，应注意在单道暗线缝制后，双边同向加道明线缝制并整烫。不透气型防酸工作服采用胶粘合制成，可选择连体式、分身式或围裙套袖，并注意服装上的通气孔不得影响服装的结构强度及使酸液侵入。
Selection should be in accordance with the body of the body in accordance with the body of acid to choose different styles of anti acid work clothes, pay attention to the acid work clothes usually do not have clear bags, so as to avoid the accumulation of splash of acid. The sewing technology can directly affect the anti acid permeability of the product. The air permeable anti acid work clothes are glued with adhesive, which can be selected as connecting type, body split type or apron sleeve, and it is noted that the air vent on the clothing can not affect the structure strength of the garment and the acid liquid invading.
