Fires in conveyor systems can have devastating consequences, including the destruction of products, equipment damage, and costly downtime. The risk of fire is heightened due to the high-speed movement of the conveyor belt, which can quickly spread flames throughout the facility. In fact, insurance claims for conveyor belt-related fires have been reported to cost an average of $8 million per claim.

The primary causes of conveyor belt fires include friction generated by a stalled or slipping belt, as well as mistracking, which can lead to the belt rubbing against the conveyor and igniting. Additionally, the accumulation of combustible materials on the conveyor bed, such as cardboard, oils, chemicals, and dust, can easily ignite and contribute to the spread of fire.

To mitigate the risks associated with conveyor belt fires, it is essential to invest in fire retardant conveyor belts. These belts are specifically designed to resist fire and self-extinguish when exposed to flames. They are constructed using special additives and chemicals in the rubber compound, which suffocate the fire by emitting gases that deprive the flames of oxygen.

Choosing the right level of fire resistance for conveyor belts is crucial. Standards and testing methods, such as EN/ISO 340 and EN 12882, provide guidance on the fire resistance requirements for different applications and environments. It is important to consider factors such as the materials being conveyed, abrasion resistance, and the presence of inflammable dust or gas.

In conclusion, fire safety in conveyor systems is of utmost importance in manufacturing plants. Investing in fire retardant conveyor belts that meet the necessary standards and testing requirements is essential to protect against the devastating consequences of conveyor belt fires. By prioritizing fire safety, manufacturers can ensure the well-being of their employees, prevent costly damage, and maintain uninterrupted operations.

Understanding Fire Retardancy in Conveyor Belts

Fire retardancy is a critical factor to consider when it comes to conveyor belts in manufacturing plants. These belts play a crucial role in the transportation of materials, but they also pose a potential fire hazard if not properly protected. Understanding the concept of fire retardancy in conveyor belts is essential for ensuring the safety of workers and preventing costly damage.

Fire retardant conveyor belts are designed to resist the spread of fire and extinguish it quickly. This is achieved through the use of special additives and chemicals in the rubber compound of the belt. These additives create a self-extinguishing effect, suffocating the flames by emitting gases that deprive them of oxygen.

It is important to note that while fire retardant belts can resist fire, they are not completely fireproof. The fabrics used in the carcass of the belt, such as polyester and nylon, have little to no resistance to fire. Therefore, every belt will burn when exposed to a naked flame with sufficient energy.

To ensure the appropriate level of fire retardancy, various standards and test methods are applied to conveyor belts. These standards, such as EN/ISO 340 and EN 12882, classify belts based on their fire resistance with or without covers. The choice between different grades depends on the material being carried and the level of abrasion resistance required.

In environments with inflammable dust and gas, additional safety measures are necessary. Anti-static properties are crucial to prevent the buildup of static electricity that could ignite the atmosphere. Belts must allow static electricity to pass through the metal frame of the conveyor structure and down to the ground.

Manufacturers play a crucial role in ensuring fire safety by producing belts that meet the required standards and conducting rigorous testing. It is essential for buyers to request technical datasheets and test results to verify the fire resistance of the belts they purchase.

By understanding the concept of fire retardancy in conveyor belts and selecting the appropriate level of fire resistance, manufacturing plants can significantly reduce the risk of fires and protect their workers and assets.

Standards and Testing for Fire Resistance

Ensuring the fire resistance of conveyor belts is crucial for the safety of manufacturing plants. To meet this requirement, conveyor belts must undergo rigorous testing and adhere to specific standards. One of the most commonly used standards is EN/ISO 340, which involves exposing belt samples to a naked flame and measuring the duration of combustion and self-extinguishing.

The duration of continued burning should be less than 15 seconds per sample, with a maximum cumulative duration of 45 seconds for each group of six tests. However, it is important to note that even if a belt passes this test, it may still carry flames over a potentially dangerous distance. Therefore, it is recommended to choose belts that self-extinguish within one second, ensuring maximum safety.

Buyers of fire-resistant belts should also exercise caution when reviewing test certificates provided by manufacturers. It is advisable to request copies of test results and ensure that the laboratory conducting the tests has EN ISO 17025 certification. This certification guarantees the competence and impartiality of the testing authority.

In addition to fire resistance, it is essential to consider the level of abrasion resistance and the specific requirements of the environment in which the conveyor belt will be used. Different grades of fire-resistant belts, such as Class 2A (K grade) and Class 2B (S grade), offer varying levels of protection based on the materials being conveyed and the wear potential.

By adhering to these standards and conducting thorough testing, manufacturers can ensure the fire safety of their conveyor belts. It is essential to prioritize safety over cost and invest in belts that meet the highest standards of fire resistance.

Choosing the Right Level of Fire Resistance

When it comes to choosing the right level of fire resistance for conveyor belts, there are several factors that need to be considered. The first step is to determine the specific application or environment in which the belt will be used. This will help determine the level of fire retardancy needed.

For general-purpose use in open-air environments, EN 12882 Class 2A or 2B is typically sufficient. Class 2A requires the belt to pass the ISO 340 test with the covers intact, while Class 2B requires the belt to pass the test with the top and bottom cover rubber removed. It is important to note that the electrical conductivity of the belt should also meet the requirements of ISO 284.

For environments where potentially combustible materials are present, such as coal dust, fertilizer, or grain, it is essential to ensure that the conveyor belt does not create static electricity that could ignite the atmosphere. In these cases, all belts should be anti-static and conform to EN/ISO 284 international standards.

In applications involving materials that contain oil, such as wood chips or biomass, it is important to choose a belt that is resistant to fire, abrasion, and oil. There are different types of oil resistance, including mineral and vegetable, so it is important to be specific when requesting quotations from manufacturers and suppliers.

It is also recommended to carry out an internal risk assessment or consult with external organizations to determine the appropriate level of fire resistance needed for specific applications. This will ensure that the chosen belt provides adequate protection against fire hazards.

By carefully considering the specific requirements of the application and choosing a belt that meets the necessary fire resistance standards, manufacturers can ensure the safety of their manufacturing plants and prevent the risk of fire damage to individuals and assets.
