Companies are required by law to conduct a respirator fit test for each employee before the initial use of the respirators in the working environment. We can help make it simple and accurate. We offer a wide range of OSHA approved fit testing kits, both QLFT and QNFT. The respirator fit testing needs to be conducted with a negative or positive pressure tight-fitting facepiece. Most importantly, it must be the same make, model, style and size of the respirator that will be used and needs to be re-tested annually.
