The Best of 2025 - Top 5 Chemical Storage Blogs

As 2025 comes to a close, we’re grateful for the opportunity to share insights through our chemical storage tank blogs throughout the year. From evolving storage solutions to essential safety considerations, our goal has been to support professionals with practical, reliable information to help maintain safe and effective chemical storage systems.

The Best of 2025 - Top 5 Blogs

In this recap, we’re highlighting the five blogs that resonated most with our readers, featuring timely topics such as best practices, emerging technologies, and strategies for maintaining safe, efficient chemical storage. We invite you to revisit these standout pieces that helped shape the conversation around chemical storage in 2025.

Best Practices For Sulfuric Acid Storage Tank Design

Sulfuric acid is one of the most widely used chemicals in the United States. This heavy, corrosive chemical requires a specifically designed storage system. That’s why Poly Processing follows guidelines that help ensure safety and enhanced useful tank life.

In this article, we’ll look at why storing sulfuric acid is such a challenge, and how we’ve adapted our tank system requirements to resolve these challenges.

You’ll learn about our tank storage requirements for your own storage needs and get access to a downloadable guide for your reference.

What's the Difference Between NSF Approval and FDA Compliance for Chemical Tanks?

It’s easy to get confused between NSF certification, FDA approval, and FDA requirements. Which terms do you need to be familiar with, and what should you expect from your chemical storage tank?

These are good questions, and it’s important to understand the differences between NSF and FDA as you prepare to purchase a chemical storage system.

Let's learn more about the difference between NSF and FDA approval for chemical storage tanks.

A Clear and Simple Guide to Annual Storage Tank Inspections

No matter what chemicals you’re storing, it’s important to conduct routine storage tank inspections. These inspections are vital to help keep the chemical tanks, fittings, venting and accessories in good working condition—and to avoid costly surprise failures.

Even new polyethylene tanks should receive routine and careful visual inspections. The tank may need to be replaced if it displays stress cracking, crazing, or embrittlement.

Follow these inspection guidelines at least annually to help ensure the safety of personnel and the preservation of the chemical you’re storing.

Safely Storing Sodium Hydroxide in Chemical Storage Tanks

Sodium hydroxide has a wide variety of uses such as making paper, water treatment in corrosion and scale control and pH adjustment, metal cleaning, electroplating, fuel cell production, medicine and even food processing. While this chemical is widely used, its properties present special storage and handling challenges.

In all forms, sodium hydroxide is highly corrosive and reactive. Exposure to sodium hydroxide, even if only for a few seconds, can result in permanent eye damage and severe chemical burns. For this reason, it is critical to ensure that caustic soda is handled and stored properly.

While there are many options for Sodium Hydroxide storage, a rotationally molded cross-linked polyethylene tank is ideal. This process produces a tank with no seams, making it nearly impossible for the chemical to find leaks.

Vent Your Chemical Storage Tank With the PolyScrub Fume Scrubber

If you're storing chemicals that emit fumes such as hydrochloric acid or hydrogen peroxide, you need to have a proper venting system in place. We've developed The PolyScrub™ fume scrubber to help you ensure the safety of your employees, equipment, and the environment.

Poly Processing's PolyScrub™ is engineered to handle discharging vapor from chemical tanks during operation and filling.

This innovative fume scrubber uses water to scrub harmful fumes before they evacuate the system. Each PolyScrub™ is designed by our application engineers to accommodate proper ACFM for a given system.
