What’s the process of becoming an FM4991 approved contractor?

There are a wide range of requirements to becoming an FM4991 approved firestop contractor. In order for a firestopping company to earn their certification, a Designated Responsibility Individual (DRI) must take an extensive, 2-hour exam, which focuses on UL Tested Systems and Code. The DRI must score 80% or higher in order to pass the exam, and then they are required to attend ongoing continuing education courses to earn CEUs, which are a requirement of keeping up their licensing. In addition, FM4991 Certified Firestop companies are subject to yearly audits by FM Research at their facility/job site in order to ensure that all standards outlined in the Quality Manual are consistently being met. As an FM4991 certified company, you know you can trust Firestop to get the job done efficiently and safely.
