Introduction
Bulwark® is a prominent provider of secondary flame-resistant apparel, focusing on safety, comfort, and durability for workers across various industries. The company offers a wide range of flame-resistant products to ensure wearer safety.
Objectives
  • Educate on the necessity and functionality of flame-resistant apparel.
  • Evaluate flame-resistant fabrics.
  • Update on advancements in fibers, fabrics, and garments.
  • Advise on changes in standards and regulatory requirements.
Introduction to FR Apparel and Standards
The document highlights the importance of understanding flame resistance and lists common industry standards and requirements for specific activities, emphasizing the need for flame-resistant garments in workplaces with ignition risks.
Flammability Standards
  • All garments must comply with U.S. flammability standards (16 CFR Part 1610).
  • Fabrics are classified into three classes based on flame spread time, with Class 1 suitable for clothing and Class 3 not suitable.
Need for Flame-Resistant Garments
  • Normal fabrics ignite and burn when exposed to ignition sources, whereas FR fabrics resist ignition and self-extinguish upon removal of the ignition source.
  • FR garments protect against clothing ignition and sustained flame spread.
Employer's Responsibility
Employers must identify workplace hazards and provide appropriate protective garments, considering flame-resistant apparel where ignition risks are present.
Choosing the Right Garments
  • Garments should offer expected protection, comfort, and durability, withstand laundering, and maintain protective characteristics.
Key Terms
  • Flame-Resistant: Resists ignition and self-extinguishes.
  • Flame Retardant: Chemical substance for flame resistance.
  • Primary Protective Clothing: For significant exposure to heat or flame.
  • Secondary Protective Clothing: For intermittent exposure.
Conclusion
Bulwark® offers a range of flame-resistant products and emphasizes the importance of selecting appropriate garments based on workplace hazards and requirements.
Introduction to Flame-Resistant Materials
Flame-resistant materials are designed to resist ignition and self-extinguish if ignited. The Arc Thermal Performance Value (ATPV) measures the incident energy on a material that results in a 50% probability of causing a second-degree burn. If the fabric breaks open before reaching ATPV, the Breakopen Threshold Energy (EBT) is reported. The lower value between ATPV and EBT is used as the arc rating.
Performance Standards and Test Methods
Various standards and test methods ensure the safety and performance of flame-resistant clothing, including ASTM standards for testing flame resistance and arc thermal performance. Key standards include ASTM D6413, NFPA 2112, and NFPA 654.
Testing Procedures
The ASTM D6413 test involves suspending fabric specimens vertically and exposing them to a flame for 12 seconds, recording results such as afterflame, afterglow, and char length.
Standards for Specific Hazards
NFPA 2112 and NFPA 2113 provide guidelines for garment selection, care, and maintenance for workers exposed to flash fire hazards, while NFPA 654 addresses combustible dust hazards.
Conclusion
Flame-resistant clothing must meet specific standards to ensure safety in hazardous environments, with testing and certification crucial for compliance with regulations and protection against fire-related injuries.
Arc Rated Clothing Requirements
Arc rated clothing is necessary if exposure exceeds 2 cal/cm², with a minimum effective rating of 4 cal/cm² required. NFPA 2112 mandates third-party approval, such as UL®, with requirements for both spaced and contact hTP, and a predicted body burn of less than 50% in mannequin tests.
Combustible Dust Hazards
Combustible dust, often a by-product of processes like grinding and sifting, poses a significant threat when accumulated in unseen areas. NFPA 654 may require flame-resistant clothing for workers at risk of exposure.
Standards for Emergency Services Uniforms
NFPA 1975 sets minimum performance and certification requirements for station/work uniforms for emergency services personnel, specifying requirements for design, performance, testing, and certification of non-primary protective uniforms.
Electrical Safety Standards
OSHA's Final Rule on Electrical Protective Equipment prohibits clothing that could increase injury extent when exposed to flames or arcs. Employers must evaluate potential hazards and determine appropriate clothing, with the National Electrical Safety Code (NESC) requiring arc-rated clothing if exposure exceeds 2 cal/cm².
Garment Performance for Electric Arc Exposure
ASTM F1506 specifies performance properties for flame-resistant textiles used by electrical workers, requiring that fabrics must not melt, drip, or have excessive afterflame or char length, with arc ratings labeled on garments.
Introduction to Protective Garments for Electric Arc Exposure
Protective garments for workers exposed to electric arcs are tested according to ASTM standards, with the arc rating, either ATPV or EBT, being a critical measure of fabric performance during arc exposure testing.
ASTM Standards for Arc Exposure
Two key ASTM standards are used for testing textiles for electric arc exposure: ASTM F1958 and ASTM F1959.
Flame-Resistant Rainwear Standards
Rainwear exposed to electric arcs and flames must comply with ASTM F1891 and F2733 standards, specifying test methods, performance requirements, and labeling for rainwear.
High-Visibility Safety Apparel Requirements
ANSI/ISEA 107 standard outlines requirements for high-visibility safety apparel, ensuring visibility in hazardous situations, with flame-resistant garments complying with specific ASTM or NFPA standards.
EN/ISO Standards for Protective Clothing
Several EN/ISO standards specify requirements for protective clothing against various hazards, including EN 340, ISO 11612, IEC 61482-2, and EN 1149-5.
Introduction
This document outlines the specifications and standards for flame-resistant (FR) clothing, focusing on the prevention of electrostatic discharges that could ignite explosive atmospheres.
Specifications and Standards
EN 1149-5 specifies design and material requirements for dissipative clothing, with the electrostatic behavior of fabrics assessed by measuring surface resistivity or charge decay.
Flame Resistance: Inherent vs. Treated
Flame-resistant fibers and fabrics are categorized into inherently flame-resistant and treated fibers, with inherent flame resistance being a natural characteristic of the fiber.
Recommendations and Warnings
Temporary water-soluble flame retardant treatments are discouraged due to potential application issues, and phosphorus-treated cotton blends are advised against in certain environments.
ASTM Standard Specifications
Flame and thermal protective rainwear must meet specific ASTM standards, including water pressure resistance and no melt and drip in vertical FR testing.
Fiber and Fabric Descriptions
The document provides detailed descriptions of various fibers used in FR clothing, including Aramid, Polyamide, Melamine, Modacrylic, FR Acrylic, PBI, Polyimide, FR Viscose, FR Cotton, FR Polyester, Carbon/Oxidized PAN, Polyamide, and Vinal.
Milliken Amplitude® Fabric
Amplitude® is a blend of 88% cotton and 12% nylon, designed to meet NFPA 70E HRC 2 and NFPA 2112 compliance, suitable for various industrial applications.
Laundry and Maintenance
FR apparel should be washed with soft water to maintain flame-resistant properties, avoiding chlorine bleach and industrial detergents with hydrogen peroxide.
Conclusion
The document emphasizes the importance of selecting the appropriate FR garments based on specific application needs, considering factors like thermal protection, static resistance, comfort, and durability.

All are required to meet the same federal flammability standard: 16 CFR Part 1610. The standard, administered by the Consumer Products Safety Commission, was originally adopted in 1954 as CS 191-53, the Flammable Fabrics Act. The purpose of the standard is to reduce the danger of injury and loss of life by providing, on a national basis, standard methods of testing and rating the flammability of textiles for clothing use. This standard does not apply to children’s sleepwear or protective clothing. The standard measures two fabric attributes: ease of ignition and speed of flame spread. A specimen...

introduction to fr apparel and standards treated fabric treated fibers Is there a need for Flame-Resistant protective garments? All fabrics made of untreated natural fibers and most synthetic fibers are combustible. It is normal and expected that they will ignite and continue to burn when exposed to an ignition source such as flame or electric arc. Because clothing constructed from these normal fabrics meets flammability requirements established by 16 CFR Part 1610, it is generally accepted as having no unusual burning characteristics.
