The Standards Organisation of Nigeria (SON) has warned importers of school uniform materials about cancer-causing substances found in some school uniform materials made by two China based companies.
Osita Aboloma, Director-General of SON who issued the warning earlier today, named the companies producing the materials as Sing Shun Fat School-Clothier Company and Zenith Uniform Company.
Aboloma said that the azo dyes found in some school uniforms in Hong Kong contained up to 173mg and 41mg/kg of the tested samples respectively, higher than the permitted level of 20mg/kg
According to him, azo dyes, which have been banned in Europe, Japan and other parts of the world prior to the finding, could release carcinogenic substances known as aromatic amines when they mix with sweat.
Aboloma advised importers of school uniform materials in Nigeria to always seek conformity assessment of such materials prior to import, through the SON off-shore Conformity Assessment Programme (SONCAP), to avoid importing unsafe products into the country.
He further advised Nigerians to report any suspected uniform materials that may already be in the country to SON for necessary sampling, laboratory tests and analysis to be carried out at its Textile and Leather Laboratory in Kaduna for necessary regulatory action.
Aboloma added that all International Accredited Firms (IAFs) undertaking the off-shore Conformity Assessment Programme on behalf of SON all over the world have been put on alert regarding the cancer-causing substance in school uniform materials and other clothing materials to be imported into Nigeria.
