Fire Safety Standards for Fiberglass Handrails and Guardrails
Fiberglass handrails and guardrails are widely used in various industrial, commercial, and public settings due to their strength, durability, and corrosion resistance.
However, an equally critical aspect of their application is fire safety, especially in environments where stringent fire codes must be met. To ensure that fiberglass handrails and guardrails provide not only structural support but also fire safety, these systems must adhere to specific standards, notably ASTM E-84.
Understanding ASTM E-84: The Standard for Fire Safety
ASTM E-84, also known as the “Standard Test Method for Surface Burning Characteristics of Building Materials,” is a pivotal fire safety standard. This test is designed to evaluate how materials behave when exposed to fire, providing vital information on their contribution to flame spread and smoke production during combustion.
ASTM E-84 is particularly significant for materials used in building construction, including fiberglass handrails and guardrails, as it helps determine their fire performance.
The ASTM E-84 test measures two key indexes
Flame Spread Index (FSI): This index indicates how rapidly flames can travel across the surface of a material. A lower FSI value suggests that the material is less likely to contribute to the rapid spread of fire, which is crucial in maintaining safety and providing occupants with more time to evacuate in the event of a fire.
Smoke Developed Index (SDI): This index quantifies the amount of smoke produced when a material burns. Since smoke inhalation is a leading cause of fatalities in fires, materials with a lower SDI are preferred because they produce less smoke, reducing the risk to human health during a fire.
The Importance of ASTM E-84 Compliance for Fiberglass Handrails and Guardrails
Adherence to ASTM E-84 is not just a regulatory requirement but a vital aspect of material selection and design for fiberglass handrails and guardrails. Ensuring compliance with this standard helps prevent fire-related incidents, especially in facilities where public safety is paramount, such as schools, hospitals, industrial plants, and commercial buildings.
When designing fiberglass handrails and guardrails, it is essential to select materials that either resist ignition or slow the spread of fire. The incorporation of fire-retardant mechanisms plays a crucial role in enhancing fire safety performance. These mechanisms often involve additives that act by capturing available oxygen, inhibiting the chemical reactions that sustain combustion, and thus reducing the risk of fire propagation.
Fire-Retardant Properties in Fiberglass Reinforced Plastic (FRP) Handrails
Design and Manufacturing Considerations for Fire Safety
Fiberglass Reinforced Plastic (FRP) handrails are specifically engineered to meet stringent fire safety standards, including ASTM E-84. FRP materials are known for their strength, corrosion resistance, and lightweight properties, but their ability to meet fire safety standards makes them especially valuable in safety-critical applications.
Key Components of Fire-Retardant FRP Handrails:
Fire-Retardant Resins: FRP handrails typically incorporate specialized resins such as fire-retardant polyester or vinyl ester resins. These resins are formulated to resist ignition and slow the spread of flames. They may contain additives that release water vapor when exposed to high temperatures, helping to cool the material and prevent further combustion.
High Glass Content: The structural integrity and fire resistance of FRP handrails are also enhanced by their high glass content. Glass fibers act as a reinforcement that not only provides strength but also contributes to the material’s fire performance. These fibers do not burn and help maintain the handrail’s shape and strength even under fire exposure.
Fire-Retardant Additives: Additives such as aluminum trihydrate (ATH) and other fire-retardant fillers are often integrated into the composite matrix of FRP handrails. These additives function by releasing water when exposed to heat, which helps to suppress flames and limit heat transfer.
Ensuring compliance with ASTM E-84 requires careful consideration of material composition and design features during the manufacturing process. Some of the critical design and manufacturing practices include:
Selection of Appropriate Resins and Additives: The choice of resins and fire-retardant additives is crucial in determining the overall fire safety of the handrail system. Manufacturers must balance the need for fire resistance with other performance factors such as strength, flexibility, and corrosion resistance.
Layered Construction: Some manufacturers use a layered construction approach where the outer layer is specifically designed for fire resistance, while the inner layers focus on structural integrity. This method can help optimize fire safety without compromising the mechanical properties of the handrails.
Quality Control and Testing: To ensure that the finished products meet fire safety standards, rigorous testing and quality control measures are essential. This often includes conducting fire tests according to ASTM E-84 and other relevant standards to verify that the handrails perform as expected under fire exposure.
Conclusion
Compliance with fire safety standards like ASTM E-84 is integral to the design, manufacture, and application of fiberglass handrails and guardrails. By incorporating fire-retardant materials, resins, and additives, manufacturers can create systems that not only meet structural and aesthetic requirements but also provide critical protection against fire hazards.
Fiberglass handrails and guardrails, particularly those meeting Class I fire ratings, play a vital role in enhancing safety in public and industrial spaces, making them an essential component of modern construction.

Frequently Asked Question
Fiberglass handrails and guardrails must comply with ASTM E-84, a standard that measures the surface burning characteristics of building materials. This test assesses how the materials contribute to flame spread and smoke production, ensuring that they meet safety requirements for fire resistance in various applications.
Fiberglass handrails and guardrails achieve fire resistance through the use of fire-retardant resins, high glass content, and specialized additives like aluminum trihydrate (ATH). These components work together to slow down the spread of flames, reduce smoke production, and maintain the structural integrity of the handrails even under fire exposure.
The Flame Spread Index (FSI) indicates how quickly flames can spread across a material’s surface, while the Smoke Developed Index (SDI) measures the amount of smoke produced during combustion. Lower values in both indexes indicate better fire performance, with materials rated under a Flame Spread Index of 25 considered highly resistant to fire spread, making them suitable for safety-critical applications.
Yes, fiberglass handrails and guardrails that meet the ASTM E-84 standard, especially those with a Class I fire retardance rating (Flame Spread Index of 25 or less), are suitable for environments with strict fire safety regulations. They are designed to limit flame spread and smoke generation, making them ideal for use in schools, hospitals, industrial facilities, and other public spaces where fire safety is essential.
