Tests conducted by Sasol and I-CAT have proven that dry chemical powder extinguishers are ineffective against rubber fires and conveyor belt and tyre fires.
Tests conducted by Sasol and I-CAT have proven that dry chemical powder extinguishers are ineffective against rubber fires and conveyor belt and tyre fires.

These tests undertaken by I-CAT and Sasol are invaluable as both these fires can be encountered in underground mining.

This means that many underground mines have little or no fire protection, posing a major health and safety risk to mine workers.

The dry chemical powder can also contaminate the air-circulation system underground, and further erode mechanical and electrical parts on machinery, causing long-term damage.

While safety has always been a critical factor in the mining industry, the tight economic climate has placed increasing pressure on the industry’s bottom line. While most mines tend to comply with the required fire regulations, few conduct proper risk-based fire protection implementation.

“To enhance the productivity of a mine, new technology is the main driver to make it more efficient at a lower total cost, which ultimately increases profitability,” says head of the fire division at I-CAT, Andro Gibhard.

“However, fire safety has lacked in technological advances, as it is mostly seen as a ‘grudge purchase’ that impacts on the bottom line,” he continues.

“Fire protection should be the first port of call for any mining operation, as the main aim is to preserve human life, without even referring to the financial and economic impact when a fire results in production downtime. It is therefore imperative that fire risk should be a primary focus when it comes to mining safety.”

It is for this reason that the I-CAT fire division has allocated considerable resources to develop the latest firefighting technology for the mining industry.

“It is only recently that mining houses are looking at more effective firefighting technologies,” notes Gibhard.

For example, the I-CAT fire division recently conducted a series of tests at a Sasol test facility to determine the effectiveness of water and foam mist systems on underground conveyor belts on coal mines.

Since most firefighting products deployed in the mining industry originate from Europe and the US, the question arises as to whether or not these have been tested for mining conditions in Africa.

“During the tests, it was discovered that widely-accepted equipment failed badly, even in controlled test environments. What then is the effectiveness in an underground mining scenario, where conditions are far less favourable than in a controlled test environment?” questions Gibhard.

The I-CAT fire division conducts scale tests on all of its products and applications.

“As a leading manufacturer of firefighting systems, we pride ourselves on conducting realistic and real-life condition testing. This is why more and more mining customers are looking to I-CAT for expert risk-based fire-suppression systems,” stresses Gibhard.

In terms of its ongoing contribution to improved firefighting methodologies for the mining industry, the I-CAT fire division has compiled a totally new protection protocol for underground conveyor belt protection, including redundancy protection.

The protocol has been tested against various test scenarios identified in a risk assessment.

Gibhard reveals that the market has responded positively due to the monthly fire information sessions, combined with live fire demonstrations, hosted by the I-CAT fire division at the South African Emergency Care fire-training facility at Modderfontein.

“At these events, we invite both safety and risk professionals to witness real fire scenarios, and how our systems perform.”

Solutions available from the I-CAT fire division include its TRT-LPS-FM system, an acronym for T-Rotor Technology – Local Protection System – Foam Mist. T-Rotor Technology is the internationally-patented low-pressure mist system powering the division’s extensive product range.

This includes protection for conveyor belts (drive, take-up, and tail-end), hydraulic power packs, transformers, and generators. These are all stored-water pressure systems, which means that an external water connection is not needed in order for them to be operational.

“The I-CAT range of products is expanding as we encounter new applications and risk environments from different customers. We have been active in the market since 2012,” notes Gibhard.

“All our product offerings are environment-friendly and not harmful to humans. We offer low-pressure systems using very low quantities of water, ensuring the conservation of this valuable resource,” he concludes.
