Chemical protective clothing in 1990, the American fire protection association (NFPA) and the American society for experimental materials (ASTM) proposed and developed additional standards, and was recognized by OSHA.The FPA1991 standard sets performance requirements for chemical - and gas-tight suits. These requirements include chemical - and flame-resistant tests for 21 basic chemicals.Fire-fighting anti-chemical Clothers is one of the protective clothing for firefighters, which can be divided into Fire fighting suit, Fire avoiding suit, Fire insulating suit and heavy protective suit.It is a protective clothing worn by firefighters to protect themselves from hazardous chemicals or corrosive substances when they are fighting and rescuing in fire and accident sites with dangerous chemicals and corrosive substances.In 1990, the American fire protection association (NFPA) and the American society for experimental materials (ASTM) proposed and developed additional standards, which were recognized by OSHA.Fire-fighting anti-chemical Clothers is a kind of protective clothing for firefighters.Fire from fire service directory 1 standard 2 forced the performance requirements such as forced introduces 3 kinds forced the hermetic chemical protective clothing forced the semi-closed chemical protective clothing forced closed protective clothing forced the heavy chemical protective clothing as much attention as much light chemical protective clothing 4 through firewire props forced the effect forced the skills a, chemical protective clothing China standard 1.

These requirements include chemical - and flame-resistant tests for 21 basic chemicals.Basic OSHA standards require level 4 protection: level A, B, C, and D. Workers at each risk level must be equipped with appropriate levels of protective equipment and protective clothing to fully protect users.Level A-- indicates the highest Level of danger and can cause harm to breath, eyes or skin, which may come from toxic vapors, gases, particles, chemical splashes, immersion or exposure to toxic materials.It requires a fully enclosed chemical protective clothing with SCBA or pipe breathing apparatus and appropriate accessories.Level A chemical protective clothing can also be made to conform to the NFPA1991 standard.Level B indicates that the environment requires the highest Level of respiratory protection, but not high Level of skin protection.It requires SCBA or positive pressure line breathing apparatus with escape gas cylinders, plus a hood, protective clothing (one-piece and long-sleeve jacket);One-piece, one or two anti-splash suits;Or can be used alone in the body of protective clothing).Provide other chemical protective clothing the future European standards: the first category: airtight type protective clothing category 2: than the third class: airtight type protective clothing liquid density type protective clothing class 4: spray type dense protective clothing class 5: dust density type protective clothing class 6: limited spray density type protective clothing is introduced using Tychem TK fabrics made big chemical chemical protective clothing, not only have excellent chemical protection performance and excellent physical properties, and in relative comfort.This product is strictly tested by ASTM and is suitable for industrial, dangerous goods and taboo accident treatment.It is resistant to toxic corrosive gases, liquids and some solid chemicals.Its protective properties have been demonstrated in various industrial applications.Can provide Level B and Level A protection.Protective chemical properties: its wide scope of protection, it can defense more than 260 kinds of high-risk chemicals, (26) a variety of dangerous chemicals through the contact Tychem TK materials for eight hours later, found no obvious infiltration in full compliance with ASTM test standard) excellent physical properties, very durable, laceration resistant features such as high visibility: Tychem TK material for orange, in the dark of the visibility is very good, in the case of taboo is safer.It's easier to see in a smoky environment.Fully sealed chemical protective clothing is the protective clothing that firefighters wear when entering the fire or accident site of chemical dangerous goods or corrosive goods, as well as the site of toxic and harmful gases or accidents, looking for the source of fire or accident point, rescuing the victims and carrying out fire fighting and rescue.Acid penetration resistance
