Nigel Thomason, British Fluid Power Association (BFPA) Distributor Chairman, has condemned hose re-ending in the mining sector as the UK’s fluid power trade association launches its ‘Choose Q for Quality’ campaign highlighting BFPA Approved Quality Members.
“The pandemic has us all under extra strain and I know that many company owners or workers across the mining industry will be looking for ways to save money – but let me tell you now, re-ending hoses to save a few pounds is not the answer,” commented Thomason.
“That’s why we’ve launched our latest campaign. We want to make sure that when you have a hose replaced, it’s done by one of our Quality Approved Suppliers who categorically will refuse to re-end hose.”
The BFPA Approved Hose Assemblies Scheme and the associated Q ‘Quality’ Logo sets practice guidelines for hose manufacturing, distribution and fitting. Members who sell and fit hoses in the scheme must meet strict criteria to carry the Q Mark, a sign of guaranteed quality, and to never practice hose re-ending.
Hydraulic hoses are found on equipment across the mining industry, including hydraulic jacks, excavators and dumper trucks, and are subject to all types of weather conditions and can get accidentally damaged onsite. A pinhole leak in a hose can eject fluid at speeds in excess of 180 m (600 ft) per second, almost as fast as a bullet, depending on the pressure it’s under.
Few professionals within the mining industry understand the dangers of pressure systems: a typical car tyre is around 32 psi, and a pressure of just 100 psi (or 6.9 Bar) is enough to puncture the skin.
It is quite normal for fluid to be under pressure at 2000 psi (168 Bar) in a hydraulic hose on a vehicle, and can be as much as 6000 psi (414 Bar). Oil under this much pressure will go straight through protective clothing, pierce the skin and can lead to severe, life-changing injuries from just one tiny looking pin prick.
This type of injury can be caused as a direct result of hose re-ending which fundamentally changes the structural make-up of the hose leading to damage and deterioration.
“Re-ending hoses is a dangerous practice which can lead to fatal injuries – ultimately you’re chancing with a liquid bullet,” added Thomason. “Cost is the biggest driver in re-ending but it’s the integrity of the whole assembly that’s ruined when you do that, not just the end of a hose. Re-ending increases the risk of failure and is never covered by the hose manufacturer’s warranty, so it really is a false economy.”
The BFPA is highlighting its campaign again now as COVID-19 restrictions are placing the mining industry under much greater financial pressure to caution against the temptation to re-end rather than use a Q Scheme approved supplier.
Company owners should check that their current and future suppliers are a member of the scheme, which is now easier to do through the updated Hydraulic Hose Safety website, which has an added ‘Find A Supplier’ section.
“Choosing a supplier that carries the Q Mark ensures efficiency. If you think about it, if your equipment is fitted with the correct hose, in the right way, by a highly qualified individual, it is simply less likely to fail. This means less downtime waiting for repairs, which in turn increases productivity and projects are completed faster.
“And most importantly, it allows company owners to sleep easy at night – knowing that the risk of a high-pressure injury from faulty practice has been eliminated,” finished Thomason.
