The company said it welcomed proposed legislation that would make retailers and distributors responsible for ensuring products they sell meet the required safety standards.
Slingsby supplies more than 35,000 workplace products across all industries, including PPE, and the company says there were a number of unscrupulous operators in the UK selling everyday products including high visibility clothing, gloves and goggles that fail to meet minimum safety requirements.
Lee Wright, marketing director at Slingsby, said: "Over the last couple of years, it's been well-publicised that cheap, substandard, and even counterfeit PPE is finding its way into the UK. A lot of the examples we have seen are badly made and fail to offer any real protection, as well as being non-compliant with safety standards. Some products even come with falsified certifications."
He added: "The fact that to the untrained eye, many of these products still look the part often makes it difficult to spot they are fake. This means it is important to buy PPE through reputable suppliers and to ensure it is certified to the appropriate British or European standards."
Manufacturers are currently solely responsible for checking products comply with performance standards, but a new European PPE directive, which is currently being circulated in draft form, would, said Wright, close a loophole that enables companies to sell substandard products without being accountable for their quality.
"Under the proposals, companies selling these products would have to keep records about their stock and ensure products meet required standards and this has to be welcome news for the industry."
