The Chinese classification standard for protective clothing is divided into heavy protective clothing and light protective clothing!
Heavy-duty protective clothing, also known as Class A chemical protective clothing, fully enclosed chemical protective clothing and airtight chemical protective clothing. Mainly used for protection involving chemical substances on the human body injury clothing, heavy protective clothing can protect the whole body or most of the human body area, protective clothing can be used in combination with other protective equipment. Mainly used for firefighters, emergency personnel and special staff to enter the chemical or corrosive hazardous places for protective clothing!
Light protective clothing is defined more broadly, in addition to heavy protective clothing, are defined as light protective clothing.
Mainly effective protection against chemical solvents, dust particles and viruses invasion protection level B, C, D level chemical protective clothing are light chemical protective clothing class applicable scope of non-extensive medical health, chemical plant operations, spraying industry and so on are used
The difference between the heavy protective clothing and light protective clothing is mainly reflected in the color, material, workmanship, feel, sealing, flexibility and comfort, The application industry and accessories are different! The U.S. classification standard for protective clothing is divided into four types of protective clothing: Class A protective clothing, Class B protective clothing, Class C protective clothing, and Class D protective clothing!
Class A protective clothing is also known as airtight protective clothing.
Class A protective clothing can withstand almost all hazardous chemicals (including gaseous, liquid or solid) in industrial production, as well as any hazardous substances. Hebei Jiuxian Class A airtight protective clothing is known internationally as the strongest chemical protective clothing. The whole suit must be equipped with positive pressure air respirator or long tube air respirator, has achieved airtightness. This type of fully enclosed protective clothing, must be regularly tested for airtightness to ensure safety in use.
1. General requirements: need to be used with air respirator and chemical protective boots and gloves. 2. Main application: highest level of respiratory and skin hazards at the same time, as well as in unknown hazardous environments.
Level B protective clothing is also known as a large number of splash-type chemical protective clothing.
Level B protective clothing, requiring respiratory protection level A, while the skin protection level is relatively lower than the level of A, able to prevent the penetration of liquid substances, but can not prevent the penetration of harmful vapors or gases. This type of protective clothing, mainly focusing on liquid toxic substances protection, rather than gaseous toxic substances.
1. General requirements: need to be used in conjunction with air respirators and chemical protective boots and gloves. 2. Main application: the highest level of respiratory hazards and lower level of skin hazards exist at the same time. Equipped when it is known to have no effect on or not penetrate the skin and only pose a threat to the respiratory system.
Level C protective clothing is also known as a small amount of splash resistant clothing.
Class C suits are comparable to Class B suits in terms of skin protection, but have a relatively lower level of respiratory protection than Class B. They provide protection against the spraying of toxic liquid substances. Can prevent the spraying of toxic liquid substances, but can not protect against toxic vapors or gaseous substances.
1. General requirements: generally need to be used in conjunction with filtering gas masks and chemical protective boots and gloves.
2. Main application: lower respiratory hazards and lower level skin hazards coexist. In known to have no effect on the skin, and already know the composition and concentration of toxic substances in the environment when equipped.
Class D protective clothing is mainly general protective clothing.
Level D protective clothing, low-level protective clothing, the skin and respiratory system are not protective performance. In the known gas substance environment, harmless to the human body and no liquid splash when equipped. 1.General requirements: applicable to general working environment, the user may be exposed to harmful dust, chemical reagents to play the role of the most primary protection.
2. Main applications: dust protection, a small amount of low concentration of chemical liquid splash.
The European classification standard for protective clothing is divided into primary protective clothing, secondary protective clothing, tertiary protective clothing, fourth level protective clothing, fifth level protective clothing, sixth level protective clothing!
First-class protective clothing: gas-tight protective clothing
For the highest level of respiratory and skin protection, protection against liquid or gaseous chemicals and solid particles
Second-class protective clothing: non-gas-tight protective clothing
For the highest level of respiratory protection, skin protection is a little weaker, protection against liquid or gaseous chemicals and solid particles
Third-class protective clothing: liquid Dense suit
For skin protection against strong spraying of liquid chemicals
Level 4 suit: Spray dense suit
For skin protection against spraying of liquid chemicals
Level 5 suit: Dust dense suit
For light skin protection against solid particles only
Level VI suit: limited liquid spray dense suit
For light skin protection, limited use, protection against light chemical sprays
