Inherent Fire Retardant

OUR PRODUCTS

Inherent Fire Retardant

Apparels made from inherent fire-retardant fabric use fibers that have built-in flame resistance. Unlike treated FR fabrics which are made by applying a chemical coating to the surface of a fabric, inherent FR fabrics are molecularly structured in a way to possess the flame-retardant properties naturally. As a result, the fabric’s fire resistance will not degrade throughout the life of the garment. Although we generally recommend to dispose the garment if it has been exposed to a hazard.

Apparels made out of Inherent Fire Retardant fabrics have a sizeable weight in the FR protective wear category. The main factors that contributed to the importance of the same are as follows:

  • Ease of use in high-temperature working zones: IFR fabrics can be made as low as 150 GSM, thus providing comfort in wearing and working with the same vis-a-vis treated FR fabrics, which can be pretty bulky.
  • Cost-effectiveness: IFR apparel is cost-effective to companies as it is durable and has a longer life span. It can easily endure the erosion of daily usage, generally up to a year, resulting in fewer replacements.
  • Adequate protection: Most IFR fabrics meet the basic FR norms for workplace hazards. So, there is no compromise on the protection levels.
  • Wide range of assortments: Different products can be created in the IFR category with a blend of natural and IFR fibres, providing plenty to choose from based on comfort, price, and protection levels.

EN ISO 11612

PROTECTION AGAINST HEAT & FLAME

Protective clothing certified according to EN ISO 11612 gives the wearer protection against brief contact with heat and flame. The heat can be convective, radiant, molten material, or a combination thereof.

The garment is classified for the following parameters

(A3) Limited flame spread-Surface Ignition
(A2) Limited flame spread Edge ignition
(B) Convective heat
(C) Radiant heat
(D) Molten aluminum splash
(E) Molten iron splash
(F) Contact Heat

ISO 11611

specifies two classes with specific performance requirements, i.e. Class 1 being the lower level and Class 2 the higher level.

  • Class 1 is protection against less hazardous welding techniques and situations, causing lower levels of spatter and radiant heat.
  • Class 2 is protection against more hazardous welding techniques and situations, causing higher levels of spatter and radiant heat.

EN 1149-5

PROTECTION AGAINST STATIC ELECTRICITY

In the petrochemical and the gas industry, workers are often exposed to explosive and flammable atmosphere.

A little spark in such locations can have fatal consequences & cause damage to life and property. Even the atmospheric humidity may influence electric discharge. In dry environments the effect of static charges can be highly destructive. An appropriate antistatic yarn used in the protective clothing prevents built up of static electricity.

EN 61482

PROTECTION AGAINST HEAT & FLAME

The standard certifies protective clothing against the hazards associated with electric arcs. During an arc blast, clothing can be exposed to flames, radiation, and metal shrapnel from electrodes. 

Therefore, it is important to wear EN 61482-certified clothing in workplaces where these hazards can occur.

NFPA 2112

PROTECTION OF INDUSTRIAL PERSONNEL AGAINST FLASH FIRE

This standard specifies the minimum performance requirements and test methods for FR fabrics and components, as well as the design and certification requirements for garments developed to protect workers from a flash fire hazard.

It requires FR fabrics to pass a comprehensive battery of thermal tests, including the following:

ASTM D6413- Vertical Flammability test Maximum two seconds after flame and four-inch char length.
ASTM F2700 – Heat Transfer Performance (HTP) test Minimum HTP of 6 cal/cm² spaced and 3 cal/cm² contact.
Thermal Stability test – Fabric must not melt or drip, separate or ignite after five minutes exposure in a 500°F or 260°C oven.
Thermal Shrinkage test- Fabric must not shrink more than 10% after five minutes exposure in a 500°F or 260°C oven.
ASTM F1930-11- Thermal Mannequin test Maximum 50% predicted body burn after three-second thermal exposure.

NFPA 70E

The National Fire Protection Association (NFPA) 70E is a comprehensive standard that establishes best electrical safety practices standards on how to protect workers from electric arc flash and arc blast exposure and resulting potential injury and death.

There are 4 Arc Hazard Risk Categories under NFPA 70E defined by the ATPV ratings:

Most people working with electricity only require clothing that meets category 1 (ATPV 4 cal/cm²) or 2 (ATPV 8 cal/cm²) protection characteristics.

NFPA 70E electrical safety standards are aimed more towards those workers who work in category 3 (ATPV 25 cal/cm²) or 4 (ATPV 40 cal/cm²) hazard situations. Their clothing must meet ATPV rating minimums throughout the life of the garment.
