Regulatory Standards for Fiberglass Tanks in Industrial Applications

In industrial environments, safety and regulatory compliance are not optional—they are operational necessities. The design, manufacturing, and installation of tanks used for storing chemicals, water, or wastewater must adhere to strict standards to minimize risk and protect both personnel and the environment. 

For those evaluating tanks for industrial use, understanding which regulations apply is vital. Learn more about tank engineering and compliance standards at Belding Tank Technologies. Fiberglass tanks have become the go-to choice for industries that require corrosion resistance, durability, and cost efficiency.

ASTM D3299 and D4097 Compliance Explained

Two critical ASTM standards guide the production of fiberglass tanks:

  • ASTM D3299 applies to filament-wound, corrosion-resistant tanks. These tanks are manufactured using a continuous filament winding process and are often used for higher-pressure applications.

  • ASTM D4097 covers contact-molded tanks, which are built with layers of resin-saturated reinforcement by hand lay-up or spray-up techniques.

These standards ensure consistent structural integrity, material performance, and long-term chemical resistance. Fiberglass tank manufacturers must meet these specifications during fabrication to ensure the reliability of their products.

Environmental and Safety Guidelines for Bulk Storage Tanks

Regulatory bodies, such as the EPA and local environmental authorities, enforce rules regarding emissions, leak detection, and secondary containment. Fiberglass storage tanks must meet containment regulations to prevent leaks that could lead to environmental damage. Some important considerations include:

  • Double-wall containment

  • Leak detection systems

  • Proper labeling and documentation

These features ensure that the tank system can handle hazardous materials safely and in compliance with regulations.

Certifications Required by Fiberglass Tank Manufacturers

To verify tank quality and performance, manufacturers often require third-party certifications. These may include:

  • NSF/ANSI 61 for drinking water system components

  • UL 1316 for underground fuel storage (Note: Belding Tank does not manufacture underground tanks)

  • ASME RTP-1 for reinforced thermoset plastic vessels

While not always legally required, these certifications help reassure industrial buyers that the tanks will meet or exceed regulatory expectations.

Impact of OSHA and EPA on Storage Tank Installations

The Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) play a crucial role in the installation and maintenance of fiberglass tanks. OSHA requires that storage tank installations consider:

  • Safe access via ladders or platforms

  • Fall protection measures

  • Confined space entry procedures

The creation of vapor control systems, spill containment zones, and appropriate material compatibility is required by the EPA. These regulations aren’t just about avoiding fines—they’re about ensuring industrial safety.

Long-Term Liability Considerations

Improperly installed or uncertified bulk storage tanks can lead to future compliance issues and high liability. Legal exposure from leaks, structural failure, or contamination can be significant. That’s why it’s essential to work with fiberglass tank manufacturers who offer engineering documentation, inspection support, and ongoing technical consultation.

A robust tank solution is more than a purchase—it’s a long-term risk mitigation strategy. Choosing compliant fiberglass tanks backed by proper certifications and manufacturing standards helps industrial buyers avoid regulatory pitfalls while ensuring operational continuity.
