Water Based Fire Protection Systems Inspection Testing and Maintenance (WBITM)

WBITM logoThe NFPA Water-Based Fire Protection System Inspection, Testing, and Maintenance (WBITM) Certification is for experienced sprinkler ITM technicians, contractors, and other professionals who have the knowledge and skills to perform the full spectrum of inspection, testing, and maintenance duties independently, without supervision.

Earning the WBITM certification demonstrates an individual’s proficiency, knowledge, and firm understanding of inspecting, testing, and maintaining water-based systems, and is a useful metric for employers to use in gauging qualifications. 

WBITM program goals

Candidates for the WBITM certification must have:

  • A minimum of 5 years of full-time verifiable work experience with inspection, testing, and maintenance of water-based fire protection systems.
  • A signed attestation from a supervisor or employer representative who can verify the applicant’s knowledge, skills, and abilities with regards to the inspection, testing, and maintenance of water-based fire protection systems. The Attestation Form can be downloaded below. For more information, download the Candidate Handbook.
