To help ensure that your water-based fire suppression system is operating properly, ATS offers NFPA 25 Fire Water Storage Tank inspection services. To keep your personnel and resources safe from fire and the extensive damage it may cause, industries are required to adhere to the NFPA (National Fire Protection Association) Regulations. In the 2017 edition, the regulation outlines the minimal guidelines for fire water tank inspections, testing and maintenance.
Frequency Guidelines for Tank Evaluations
- Fire Water Tank Interior – Every 5 Years – Per 9.2.6.1.2
- Fire Water Tank Interior without Corrosion Protection – Every 3 Years – Per 9.2.6.1.1
- Exterior of Fire Water Tank – Quarterly – Per 9.2.5.1
Based on the frequency guidelines above, ATS’ qualified inspectors offer visual testing that meets the specified requirements.
Visual Testing Process
To make the inspection process more efficient for you and your facility, ATS offers underwater evaluations using our technically advanced submersible remote operated vehicle (ROV). This visual inspection process can be more cost effective than hiring a diver to perform inspections besides being a time saver, allowing you to achieve quality inspections without having to drain your tank(s).
Per 9.2.5.4 – Required Tests for Interior Pitting, Corrosion, or Coating Failures
If pitting, corrosion, and coating failures are discovered during the visual inspection process then NFPA 25 requires additional testing on a drained tank. Our experienced personnel have the expertise to perform these additional tests if necessary.
Additional Testing:
- Adhesion Testing — Cross Hatch Test
- Dry Film Thickness Measurements
- Vacuum-Box Testing
- Ultrasonic Thickness Testing on Tank Walls and Tank Bottom
- Spark Testing / Wet Sponge Testing
Internal and External Tank Components
Internal and external tank components can present vulnerabilities subject to failures and discontinuities. Based on specifications, our thorough inspection procedures may also include evaluations of the following components:
- Valves
- Piping
- Fittings
- Hangers, Braces, and Supports
- Drains
- Support Structures
- Vents
- Foundation
- Catwalks
- Ladders
- Exterior Surface — Paint, insulation, etc.
ATS can assist your facility in establishing an ongoing compliance program that meets NFPA 25 Standards. This program outlines chronological and routine inspections required by NFPA and can help you maintain the required records. This is an important and conventional aspect for your business when it comes to having successful safety and quality assurance audits.
