The coupling between tractor and trailer failed at 09:14 as a 28 m³ tanker turned off the weighbridge. The trailer went onto its side, the manhole cover sheared, and by the time the driver was out of the cab an estimated 9 m³ had spread across 180 m² of concrete apron, with 4 m³ running into a surfa…
A gelled container is meant to be the safe version of a liquid load. That is precisely why a spill of gelled waste is mishandled: it looks solid, so it gets treated like a dropped bag of rubbish rather than a contaminated liquid event. A dropped 5-litre drum can distribute gel across four square met…
The comparison usually starts with price per kilogram, which is the one number that guarantees the wrong answer. Sawdust at USD 0.20/kg looks like a fifth of the cost of polymer at USD 3.20/kg. Then you work out that you need 350 kg of sawdust to take up a 1,000-litre spill that 7 kg of polyacrylate…
A 200-litre tote of water-miscible coolant let go across a bunded floor at two in the morning. The shift supervisor has four 25 kg bags of polyacrylate in the store and needs to know whether that is enough, too much, or hopelessly short. The answer is arithmetic, not judgement, and it takes about ni…
A 25 mm slurry hose at 1.5 m3/h releases about 25 litres a minute. If it splits at the coupling behind the operator’s back, and it takes four minutes for someone to notice, that is 100 litres of polymer slurry across the yard — and the yard is on a slope toward the surface water drain. What a …
