Fire Resistant Clothing Materials

Gypsum board also known as drywall consists of a layer of gypsum sandwiched between two sheets of paper.

Fire resistant clothing materials.

Fire retardants may also cool the fuel through physical action or endothermic chemical reactions. A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. Flame retardant clothing on the other hand is made from materials that have been chemically treated to achieve the same self extinguishing properties. Many structural materials will require underlying gypsum sheathing in order to achieve a good fire resistant rating and gypsum board is the most commonly used fire resistant interior finish.

Polartec started developing performance flame resistant fabric technologies for the u s. These materials will need to be consistent with the original materials used to create the garment so the entire piece retains its flame resistant attributes. Military in 2003 after combat uniforms began melting against the intense heat of ied detonations. Correctly repairing fr clothing requires flame resistant materials.

Fire retardant materials should not be confused with fire resistant materials. This necessity to enhance safety abilities of fabrics used to protect against worksite hazards became a practical fit for commercial workwear applications. Decorating wedding fashion. Synthetic acrylic polyester and nylon fabrics can be hazardous when they burn because the materials can melt and cause burns on the skin when used as clothing fabrics.

Repairing fr clothing with non flame resistant materials can result in the entire garment being compromised and failing. Despite this danger these synthetic fabrics are considered fire resistant fabrics because they resist ignition at much higher temperatures than natural fibers. Fire resistant materials which are designed to resist burning and withstand heat. Fire retardant materials are designed to burn slowly.

As you can see the main difference in these two types of clothing are in the garment material. Refinery workers electricians foundry workers maintenance workers and power and electric utility workers wear fire resistant clothing in the course of their daily duties. Fire resistant materials should self extinguish once the source of ignition is removed. This type of clothing does not comply with the 269 standard if it can ignite and continue to burn under the electric arc and flame exposure conditions found at the workplace.

The amount of heat required to ignite these materials is dependent upon a number of factors including the weight texture weave and color of the material.
