first of all you know who imported those substandard cylinders, so he or she needs to be immediately arrested for breaking the law. second, those import that are not of standard should be immediately destroyed and not allowed into the country. finally, why in God name is Nigeria importing cylinders. we have oil companies that are building infrastructure for oil companies, pipelines, gas processing facility. is the no way to have one of this companies making cylinder for Nigeria market. very sad how we allow importation to destroy our country.
