The Selection and Use of Protective Clothing(Disposable Coverall), As Well As Its Classification and Standards

Selection and Use of Protective Clothing(Disposable Coverall)

Protective clothing is classified into the following four levels according to its different applications:

Level ALevel BLevel CLevel D
Air-tight chemical protective suitChemical protective suit with large splash resistanceChemical protective suit with small splash resistanceOrdinary protective clothing
General requirements: It needs to be used in conjunction with an air respirator and chemical protective boots and gloves; Main application: It is used when the highest level of respiratory and skin hazards coexist simultaneously, as well as in unknown dangerous environments.General requirements: It needs to be used in conjunction with an air respirator and chemical protective boots and gloves; Main application: It is used for the highest level of respiratory hazards and lower skin hazards that coexist simultaneously.General requirements: It generally needs to be used in conjunction with a filtering air breathing device and chemical protective boots and gloves; Main application: It is used for lower respiratory hazards and lower skin hazards that coexist simultaneously. Main application: Dust protection, and splashes of a small amount of low-concentration chemical liquid.General requirements: It is suitable for a general working environment and provides the most basic protective effect against harmful dust and chemical reagents that the user may come into contact with. Main application: Dust protection.

European Standard Classification of Protective Clothing

European Protective Clothing TypeDescriptionMarkApplication Environment
Type 1 (EN943-1, EN943-2)Air-tight protective clothingIt is used in the most dangerous environment where both respiratory and skin hazards coexist simultaneously, and is an indispensable emergency material in chemical production, fire fighting and other dangerous environments.
Type 2 (EN942-1)Non-air-tight protective clothing
Type 3 (EN14605)Liquid-tight protective clothingIt is used in pressure washing operations, tank/chemical container cleaning operations, agricultural spraying operations and pesticide treatment, chemical mixture preparation (low toxicity), acid and alkali chemical operations.
Type 4 (EN14605)Spray-tight protective clothingIt is used in chemical product handling, chemical waste treatment, emergency incident handling, polluted environment treatment, etc.
Type 5 (ENISO13982-1 (&2))Protective clothing against solid particulate matterIt is used in harmful dust and low-level chemical liquid splashes, asbestos dust, insulation material installation, wood and metal processing.
Type 6 (EN13034)Protective clothing against mild chemical liquid splashesIt is used in general maintenance and cleaning operations, and other ordinary industrial operations.
