Safety First
Preventing leaks and spills protects your workforce and the environment.

Chemical Compatibility
Different chemicals react differently with tank materials. A mismatch can lead to corrosion, leaks, or contamination.

Define Your Needs
Our experts can guide you in deciding the perfect tank for your unique chemicals. Some need to be concealed while others won’t handle the pressure in a closed chemical container.

Storage Capacity
You’ll need a tank that can accommodate both your current and future storage needs.

Location
Will the tank be used indoors or outdoors? Will it be above-ground or underground? These factors influence the choice of material and installation.

Regulatory Compliance
Compliance with standards such as UL, EPA, NFPA regulations or OSHA guidelines ensures legal and environmental safety.

The Chemical Tank Inspection Imperative

Routine inspections are critical for early detection of any potential issues. Depending on the chemicals stored, tank material, and the environment, inspections should be weekly, monthly, or quarterly.

What to Look For

• Visible Damage: Look for stress fractures, , or bulging that may indicate structural problems.
• Corrosion: Pay attention to metal tanks or fittings susceptible to rust.
• Discoloration: Color changes on the tank surface could be a sign of chemical reactions.
• Fittings and Valves: Ensure all connections are tight and wear-free.

Pro Tip: Always document inspections with notes and photographs for future reference.

Cleaning: More Than Just a Rinse

Cleaning chemical containment tanks prevents contamination, especially when switching the type of chemicals stored. It can range from a basic rinse to a complete decontamination process.

Steps for Effective Cleaning

1. Drain the Tank: Safely remove all contents.
2. Rinse: Use high-pressure water to clear out residues.
3. Use a Cleaning Solution: For stubborn residues, apply a compatible cleaning solution.
4. Scrub: Use brushes to scrub the walls and base. Long-handed brushes are your pal here.
5. Rinse Again: Remove all cleaning agents before refilling.

Always ensure the tank is completely dry before refilling with chemicals.

Ventilation and Pressure Management

Improper pressure management can cause tanks to rupture. Volatile chemicals often release gases, so proper ventilation is key.

Best Practices

• Install venting systems suited to your tank’s size.
• Regularly check and clean vent filters.
• Use pressure relief valves to prevent ruptures.

Monitoring pH and Chemical Compatibility

Different chemicals have different personalities. Some are acidic divas, others are alkaline prima donnas. Regular pH monitoring ensures your tank material remains compatible with its contents while keeping potential risks at bay.

Key Considerations

• Use pH monitoring systems regularly.
• Ensure tank materials are compatible with stored chemicals (e.g., HDPE tanks for corrosive substances).

Consult with professionals if unsure about material compatibility

Routine Maintenance Schedule  

Establishing a routine maintenance schedule ensures that issues are addressed promptly, and your tank remains in optimal condition.
