Protective Fabrics Introduction to Flame Retardant Fabrics International standards & regulatory measures BIS standards Recommendations
Fabric flammability is an important issue, especially for stage drapery that will be used in a public space such as a school, theatre or special event venue. Although all fabrics will burn, some are naturally more resistant to fire than others. Those that are more flammable can have their fire resistance drastically improved by treatment with fire retardant chemicals.
Importance of FR Textiles For Public Safety • Recent studies have revealed that in 24 % of fire accidents, the first item to catch fire is textiles • 28 % casualties were due to burns; • 48 % due to smoke/gas; • 13 % due to combined effects of burns, gas and smoke; • 11 % due to other causes. These emphasize the role of textiles in limiting the spread of fire and casualties due to it.
Importance of FR Textiles For Public Safety • Heavy damage to property and loss to valuable lives due to fire • Fire safety in public places/buildings has assumed paramount importance • Fires in exhibition (Meerut), marriage pandal (Hissar), Uphar Cinema are living examples • Record loss of life due to fires in India is amongst the worst in the world • Fires are second largest cause of unnatural deaths in India • In terms of insurance claim also, fires account for losses of Rs. 1 Crore and above • In view of violation of public safety norms in India, fire safety legislation is the need of the hour • Strong need to implement latest standards on fire retardant textiles by enacting and enforcing fire safety legislation and guidelines specially for the public places/buildings and for children wears.

Fire Terminologies Flame Retardant A substance applied to or incorporated in a combustible material to reduce or eliminate its ability to ignite when exposed to a low energy flame resource (i.e. match or cigarette). Flame Proof A material which is totally resistant to fire or flame (i.e. asbestos). Flame Resistant A material which does not continue to burn or glow once the ignition source has been removed. After Glow Smouldering ambers present when primary ignition source has been removed.
Evaluation Parameters for FR Textiles • Ease of Ignition • After Glow Time • Extent of After Glow • Char Length • Flame Spread Time, Debris or Drips • Smoldering Time • Limiting Oxygen Index • Heat Transmission Factor • Heat Transfer Index • Molten Metal Splash Index • Smoke Opacity • Toxicity
Standardization • Why Standardization Required: • The users need to be certain that they are sufficiently protected. • The manufacturers want to show to the users that their product fulfils their needs of protection. • The test laboratories want to have approved and standardized test methods in order to get reproducible results and standardized performance requirements as a guideline for the certification of products.
The problem of standardized tests is that the test conditions are far away from the conditions in real use (Zimmerli, 1996). In the last few years due to better understanding of the subject, it is said that the complete protective clothing has to be tested, either in a practice test with test persons or with an instrumented mannequin (Zimmerli, 2000). • In addition, it will be necessary to assess the protective and the comfort properties simultaneously, because in most cases there is a strong interaction between the two properties.
Organizations to set standards • ISO standard-setting body composed of representatives from various national standards organizations. • CEN- The European Committee for Standardization it's 30 National Members work together to develop voluntary European Standards (ENs) • ASTM- American Society for Standardisation and Materials, in US it develops standards on protective clothing • NFPA - The National Fire Protection Association (NFPA) writes performance standards for fire fighters’ clothing, based on test methods standardized by ASTM. • BIS is the Official National Standards Body of India covers product quality certification, consumer affairs and development of technical standards .
US Flammable Fabrics Act(codified at 15 U.S.C 1191-1204) • Legislation is to keep away the use of dangerously inflammable textiles out of commerce in USA • The act covers trading of fabrics meant for wearing apparel or interior furnishing when they are traded with importers in USA • Manufacture, sale, importation into USA, introduction of flammable fabrics shall be prohibited • Importers are advised to buy from a supplier issuing a guarantee and a test report • Consumer Products Safety Commission is vested with the powers of determination of – authority to test, testing standards & prosecution powers
USA Flammable Fabrics Act • Enforcement mechanism: • Consumer Products Safety Commission administers the enforcement mechanism • Imported fabrics are not allowed to be cleared out of customs warehouse unless it is FR • In case imported fabrics are released against bond by customs ware house, they can order for return to customs warehouse • Can seize and send for testing • File civil suit based on lab report • Levy fine up to $ 100,000 • Penalty is based on gravity of injury that would have caused or likely to have caused • In the event of misrepresentation, the merchant is liable for imprisonment up to 5 years.
National Standards (Test methods) Developed by the National Fire Protection Association (NFPA), titled NFPA 701: Standard Methods of Fire Tests for Flame Propagation of Textiles and Films. There are no “official” federal regulations regarding FR of drapery fabrics used in public spaces. However, Under NFPA 701, drapery fabric is tested by burning a small sample and measuring the flame, char length & flaming residue • if a fabric meets these three areas, it is considered as flame retardant.
State and Local Regulations • Though NFPA 701 is the national standard, it is not a law or regulation in itself. • Authority to make and enforce laws and regulations in this area is granted to state and local governments. • Many state and local governments have not developed their own standards. Instead, they require that draperies used in public spaces meet the NFPA 701 standard. • The 2005 Florida Fire Prevention Code, for example, specifies in Chapter 20 that fabric used in places of assembly must meet NFPA 701 standards.
State and Local Regulations Some states and cities, however, have developed their own standards and/or procedures. These requirements are separate and distinct from NFPA 701 standards.
State and Local Regulations While the State of New York and the Commonwealth of Massachusetts both accept NFPA 701 certification, New York City requires certification that fabrics meet requirements outlined in Title 27 (Chapters 1 and 4) of the New York Administrative Code, In California, for example, drapery used in public spaces must be made of fabric that has been registered with the State Fire Marshal, documenting compliance with Title 19 (Division 1, Chapter 8) of California Code of Regulations. while the City of Boston requires that end users submit an application for a use permit, in advance, for each fabric to be used in a public space.
State and Local Regulations Venue Requirements Even specific venues have developed their own requirements for drapery to be utilized within the venue. Radio City Music Hall, in addition to requiring that all fabrics be certified compliant with New York City regulations, also requires the Certificate of Flame Retardancy include not just basic information on the fabric utilized, but specific information about each sewn drapery piece, including quantity and size.

Recommendations… • In view of public safety and property loss as well as high environmental pollution involved in fires, it is necessary that relevant Indian standards are made mandatory for textiles used in public places / buildings - hospitals, schools, airports, theaters, shopping complexes, railways, civil aviation, automobiles etc. • Legislation for FR textiles are already in force in many of the developed countries of the world and India should be no exception to this.
RECOMMENDATIONS… • Standards on FR textiles - IS15741:2007, IS15742:2007, IS15748:2007 & IS15768:2007could be made mandatory under the BIS Act. • Subsequently, standard for resistance to ignition of mattresses, divans and bed bases to be made mandatory after publication. • Standards developed by BIS on FR textiles need to be included in National Building Code of India 2005 immediately as a separate chapter. • In order to prevent the import of sub-standard and hazardous FR textiles, the relevant Indian standards could be made mandatory for imports also.
CONCLUSION • All out efforts by all stake holders required to minimize fire hazards by use of FR textiles and enforcing suitable fire safety legislation for safety in public places/buildings. • Role of standards in minimizing fire losses is of paramount importance. • Awareness of latest developments at International level is required. • With the pace of globalization, infra structural growth and changing public safety concepts, any neglect in public safety including use of FR textiles shall cost us dearly. • The opportunities thrown open by the growing market for FR fabrics need to be thoroughly exploited by India.
