How to Choose Flame Retardant Conveyor Belt?

When searching for the best practices on selecting flame retardant conveyor belts, multiple sources highlight the critical importance of fire resistance for conveyor systems. A lack of appropriate fire safety measures can lead to disastrous scenarios, especially in environments where combustible materials are present.

Understanding the functionality of conveyor belts is essential as these systems play a pivotal role in many industries. If a conveyor belt fails, it can result in substantial operational downtimes, associated costs, and even potential safety hazards.

If a conveyor belt does not meet the manufacturer's specifications—such as premature wear or susceptibility to heat and oils—the immediate risk to safety may seem minimal. However, if a fire retardant belt fails to perform during a fire incident, it can spread flames quickly across the site, resulting in severe consequences.

Assessing Safety vs. Cost

In today's economic climate, companies often feel pressure to reduce costs, which can lead to compromises in safety standards. Unfortunately, this trend raises the question: are operators prioritizing cost over safety? The repercussions of choosing cheaper, non-fire-resistant belts can be incredibly expensive, not to mention dangerous.

Many organizations are reportedly replacing fire-resistant belts with less effective options solely for financial reasons. One insurance firm reports claims related to conveyor belt fires averaging nearly $8 million each.

Understanding Fire Resistance

One crucial fact to remember is that no conveyor belt can be completely fireproof. While special additives can make the rubber more fire-resistant, the underlying materials often consist of polyester and nylon, which inherently lack flame resistance. Understanding the specific fire resistance requirements for your application is critical for making the right choice.

Addressing Hazardous Environments

For settings that are prone to ignitable dust and gases, regulatory standards like EN provide safety guidelines for conveyor belts used in various environments. It's essential for such belts to not generate static electricity that could ignite surrounding atmospheres. A manufacturer that prioritizes safety will ensure that their belts are anti-static and comply with standards like EN/ISO 284, making them suitable for ATEX classified areas.

In environments at risk of explosions, it's imperative to request safety documentation from suppliers that verify compliance with independent testing authorities.

General Service Applications

In general service applications, fire resistance classifications and independent testing methods are vital for ensuring safety. Two critical grades of fire resistance exist: K (fire resistance with covers) and S (fire resistance with and without covers). Determining which grade to use should consider the materials the conveyor will transport—higher abrasion rates may necessitate selecting the S grade.

Furthermore, technical datasheets from manufacturers provide necessary insights into wear resistance, as fire-resistant compounds can wear down faster, reducing their protective capabilities.

Testing Standards

Testing methods such as EN/ISO 340 are essential for measuring the flame resistance. A conveyor belt's ability to self-extinguish after exposure to fire is crucial in preventing the spread of flames over larger distances. Gaining visibility into testing results from manufacturers ensures that safety standards are met.

Choosing the Right Grade

Determining the fire resistance needed often poses a challenge. For most conveyors operating in open-air conditions, EN Class 2A or 2B proves adequate. Conducting a risk assessment can greatly assist those uncertain about required specifications.

With this extensive overview, it’s crucial to weigh the costs against safety. Do not settle for subpar options when the stakes involve the safety of both personnel and property.

For specialized needs like conveying oil-containing materials, selecting rubber compounds that are fire, abrasion, and oil resistant is vital. When sourcing quotes from manufacturers, provide detailed specifications to ensure that your chosen conveyor belt meets all safety requirements.

Conclusion

It's essential to verify that your selected conveyor belt not only meets but exceeds the appropriate safety standards. Inquire about additional testing and documentation. The cost of neglecting fire safety can have repercussions that far outweigh initial savings.
