Protective clothing is widely used in different regions of the world and meets the needs of certification standards for protective equipment in different regions. One of the more rigorous is the United States OSHA classification standards and European EN classification standards, to ensure that personnel in the use of the process of safety, fast.

Protective clothingIn different regions of the world have a wide range of applications, and meet different regionsProtective EquipmentRequirements for certification standards. One of the more rigorous is the United States.OSHAClassification criteria andEuropeENClassification standards to ensure that personnel are safe and fast during use.

United StatesOSHA(Remarks:Occupational Safety and Health actS. Occupational Health and Safety Act) classifies protective clothing according to its different applications as followsABCDFour levels:

ALevel Airtight protective clothing
1.General requirements: needair respiratorUse with chemical protective boots and gloves.
2.Primary Application: When the highest level of respiratory and skin hazards are present at the same time, and in unknown hazardous environments.
AGrade Chemical Protective ClothingIt can resist almost all hazardous chemicals (including gaseous, liquid or solid) in industrial production, as well as any dangerous substances. solidALevel air-tight protective clothingIt is internationally known as the strongest chemical protective clothing. The whole set of clothing must be equipped with positive pressure air respirator or long tube air respirator, has reached the airtight. The typeFully enclosed protective clothingAir tightness must be tested regularly to ensure safety in use.

BLevel Massive splash typeChemical protective clothing
1.General requirements: need to be used with air breathing apparatus and chemical protection boots, gloves.
2.Primary Application: When the highest level of respiratory hazard and lower level of skin hazard are present at the same time. It is equipped when it is known that it has no effect on the skin or cannot penetrate, but only poses a threat to the respiratory system.
BLevel protective clothing, requiring respiratory protection level upAlevel, while the skin protection level is relatively lowerAThe level can prevent the penetration of liquid substances, but cannot prevent the penetration of harmful vapors or gases. This type of protective clothing mainly focuses on the protection of liquid toxic substances, rather than gaseous toxic substances.

CLevel A small amount of splash chemical protective clothing
1.General requirements: General needs and filter typeGas MaskUse with chemical protective boots and gloves.
2.Primary Application: When a lower respiratory hazard and a lower level of skin hazard are present at the same time. When it is known that it has no effect on the skin and has known the composition and concentration of toxic substances in the environment.
CGrade protective clothing, the level of skin protection and.BThe level of protective clothing is equivalent, but the respiratory protection level is relatively lower.BLevel. Can prevent the spray of toxic liquid substances, but can not protect the toxic vapor or gaseous substances.

DLevel General protective clothing
1.General requirements: applicable to the general working environment, the user may be exposed to harmful dust, chemical reagents play the most primary protective effect.
2.Main application: dust protection, a small amount of low concentration chemical liquid splash.
DLevel protective clothing, low-level protective clothing, the skin and respiratory system do not have protective performance. Equipped in known gas environment, harmless to human body and no liquid splash.

EuropeENStandard will be divided into six categories of protective clothing can be entrusted to the agency for T1366 1555 246

European standards stipulate that chemical protective clothing must meet the requirements of European standards for personal protective equipment (PPE), and“Ⅲ”class requirements, and define6After the fabric performance test and the actual field test of the comprehensive performance of the finished product, the following categories are obtained:
