SAFETY 1 that a custom fire suppression system can be installed.” In addition to the excellent performance of I-CAT’s fire suppression technology, Van der Merwe adds that there is another reason to look at the company’s fire suppression solutions. “All of our applications and product offerings are environmentally friendly, because they use water rather than chemicals, and so there is no danger of contaminated runoff,” he explains. “Even the extinguishers that include a foaming agent are more environmentally friendly than similar products on the market, partly because of the additive itself, and partly because we only add 0.5% foaming agent to the mix, compared to about 6% the industry usually adds.” Fire Orbs The FST Fire Orb is a unique self-activating, portable fire-extinguishing device that activates automatically when in contact with open flames. 30 _ QUARRY SA | JANUARY/FEBRUARY 2018 2 Centurion-based Fire and Security Techniques recently introduced an easy-to-use, cost- effective new fire-extinguishing device to the local market – the FST Fire Orb, a unique, self- activating, portable fire-extinguishing device that activates automatically when in contact with open flames. Effective for use against all types and classes of fires, from electrical shortages to vehicle, workshop and factory fires, the FST Fire Orbs can be wall-mounted for maximum effectiveness, according to Fire and Security Techniques CEO, Neil Hughes. Each FST Fire Orb weighs only 1.3kg, making it lightweight and easy to handle and operate, and comprises a lightweight case of frangible material, with a protective exterior sheathing. The internal cavity contains a pyrotechnic detonator at or near the centre of mass. 1 & 2: The final demonstration on the day entailed setting alight the on-site structure, and then extinguishing the fire using I-CAT’s vehicle-mounted Blaze Buster system. Activated by fuse cords extending to the surface, the device is filled with monoammonium phosphate, a non- conductive dry chemical powder, which means it can be used on any electrical product without resultant damage. The detonator incorporated in the FST Fire Orb is a small, non-lethal explosive mechanism. The use of low-density, low- mass components means that no part of the device has sufficient mass or density to constitute a ballistic hazard, or result in concussive shock. The FST Fire Orb activates automatically upon direct contact with open flames rather than heat, and is simply rolled or thrown into the fire, where it activates within three to seven seconds. Upon activation, it emits a loud bang of between 119dB and 138dB as a warning signal, and disperses the dry chemical powder to extinguish the fire. The FST Fire Orbs have passed tests conducted by the PSB Corporation and Sirim Qas International for Class A, B and C fires. Additional tests carried out include thermal resistance, burst effect, sound level, compression resistance and drop tests. The devices are regulated and certified in accordance with ISO 9001: 2001, and have also been approved and classified by the South African Police Service. “We offer a free risk-assessment service for all clients interested in the product, where our risk-assessment manager advises suitable installation requirements pertaining to customer specifications,” says Hughes.
