The standards for inspecting water tanks encompass both the procedures for assessment and maintenance, as well as the expected safety levels resulting from these practices. Organizations such as the National Fire Protection Association and the American Water Works Association establish comprehensive guidelines and specifications tailored to each water tank and its intended functions.
Promoting Fire Safety: National Fire Protection Association
The National Fire Protection Association (NFPA) is an international nonprofit organization focused on promoting fire and life safety. It develops and publishes codes and standards related to fire protection, including regulations for fire water storage tanks.
The American Water Works Association (AWWA) is a nonprofit organization representing the largest community of water professionals worldwide. It provides education, resources, and advocacy to promote safe water practices. Additionally, the AWWA publishes standards and guidelines covering various aspects of water supply and treatment, including regulations for potable water storage tanks.
NFPA Standards for Panel Tanks
NFPA standards for fire water storage tanks are detailed in NFPA 22: Standard for Water Tanks for Private Fire Protection. Chapter four of NFPA 22 outlines general requirements, with subsequent chapters addressing specific types of water tanks. Compliance with these requirements and specifications can enable tank inspection companies to obtain NFPA certification.
Overarching Standards:
NFPA standards for fire water storage tanks, as detailed in NFPA 22: Standard for Water Tanks for Private Fire Protection, establish various requirements and specifications to ensure the safety and reliability of these tanks.
Key Points from the General Requirements Include:
- Capacity and Elevation: Tank size and elevation are determined based on the specific conditions of the property.
- Water Sources: The water source for the tank must be adequate and reliable, with consideration given to future reliability.
- Location of Tanks: Tanks must be positioned to protect both the tank and nearby structures from fire exposure.
- Tank Materials: Approved tank materials include steel, wood, concrete, coated fabrics, and fiberglass-reinforced plastic.
- Workmanship: Tank manufacturers must meet specified requirements and deliver structures that demonstrate reliability under specified conditions.
- Plans: Contractors must submit stress sheets and plans for approval by the relevant authority to obtain building permits and licenses.
- Tank Contractor Responsibility: Experienced contractors are responsible for ensuring all work is performed with care and expertise. Completed tanks are tested for water tightness before official inspection.
- Attachments to Tank Structures: Any attachments, such as signs or flagpoles, must be specially designed for the purpose.
- Strength: Tank materials must be free of defects that could affect their strength or performance.
- National Standards: Only materials that meet recognized national standards are permitted.
- Roof Standards: All tanks must have roofs, with OSHA-compliant standard railings installed around roof utility holes and other access points.
- Roof Vent Standards: Essentially airtight steel roofs require vents above the highest water level, equipped with corrosion-resistant screens to prevent contamination.
AWWA Standards for Water Tank Inspection
AWWA standards for water tank inspections are detailed in AWWA D100: Standard for Welded Carbon Steel Tanks for Water Storage. This standard outlines design, fabrication, and construction requirements for potable water storage tanks, as well as guidance on maintenance and inspection procedures.
Similar to NFPA standards, AWWA standards encompass various specifications and guidelines for different aspects of water tanks. This includes design criteria, specifications for accessories, and recommendations for tank location to ensure compliance with safety and quality standards.
Why Following NFPA and AWWA Standards is Crucial for Safe Tank Inspections
Both the NFPA and AWWA underscore the significance of routine maintenance and inspections for water tanks, establishing minimum requirements for these procedures. Their guidelines are pivotal in safeguarding the integrity of water tanks and ensuring a safe, potable water supply for consumers.
It’s noteworthy that the standards outlined by these organizations serve as minimum requirements and may not comprehensively address all jurisdictions. Local codes and regulations might impose additional mandates for water tank maintenance and inspection, reflecting unique regional considerations and circumstances.
