SpillFix Universal Organic Absorbent is an industrial absorbent product made from natural coir (coconut husk). Flammability tests (as detailed below) have determined that the product is a Not Readily Combustible Solid, and is unlikely to catch fire even after absorbing flammable spills.
The tests for determining flammability of the SpillFix Universal Organic Absorbent are based on the Burning Rate Test as per Clause 22.214.171.124.3.2 in the UN recommendations.
A flame (min. temperature 1000C) from a gas burner was applied to a 200mm strip (20mm wide, 10mm high) of SpillFix Universal Organic Absorbent for 2 minutes.
The strip of product did not burn within the 2 minute test period, smouldering only at the place exposed to the flame.
The conclusion drawn was that SpillFix Universal Organic Absorbent should not be classified as a flammable solid. It can be classified as Not Readily Combustible Solid of Division 4.1.
The flammability of SpillFix Universal Organic Absorbent and Diatomite were compared by allowing a 200mm strip of each product absorb oil AWS 68. Hot flame from a gas burner was then applied for 2 minutes to each strip.
The product Diatomite caught fire, while SpillFix Universal Organic Absorbent only smouldered.
It was concluded that since Diatomite has less absorbing capacity, more of the oil was released when exposed to the hot flame. SpillFix, with its greater absorbing capacity, retained the absorbed oil and did not catch fire.
However, both products should be used with caution when absorbing flammable spills.
