Why is FM Approval Important?

Many folks often recognize the UL (Underwriters Laboratory) Listing and FM (Factory Mutual) Approvals marks, but few understand what each of these marks means. If you’re a regular follower of the Steven Brown & Associates blog, you’ll know we recently outlined the meaning behind a UL Listing mark. Today we wanted to dive into FM Approval, and exactly what that means in relation to the realm of fire pumps.

Factory Mutual (FM) Global is similar to Underwriters Laboratories (UL) in that they both are focused on safety. FM Approvals is the independent testing division of FM Global, and it focuses on researching and testing all products to ensure that they meet only the highest standards for property loss prevention and safety.

Only those products that bear an FM Approved mark conform to these high standards and have met the ongoing requirements of the FM certification process. This is a 5 step process that includes:

  1. A manufacturer request
  2. Proposal issue and manufacturer authorization
  3. Review, testing & first audit
  4. Report, FM Approved Mark and Listing
  5. Surveillance audits

In the realm of fire pumps, FM Approval means that the fire pump has been designed for reliable performance during a critical time – when someone is dealing with a fire. A fire pump that fails when called upon can cost thousands of dollars and even lives, so it’s crucial pumps perform when needed.

  • In-line
  • Horizontal split-case and vertical shaft, turbine type centrifugal
  • Vertical turbine barrel

With most standard electric motors, there’s a built-in safety system to save the motor before damage occurs. During a disaster like a fire, this is certainly not what you’d want to have happened, as you’d want to ensure proper operation. Fortunately, this is not the case for those fire pumps receiving the UL Listing and FM Approval marks, as these pumps will run until they can no longer function. The bottom line is that the FM Approvals mark is your assurance that a fire pump is tested and reliable.
