Ethanol Storage — 70-95-99% & E85 Biofuel Tank Selection (Class IB)

Storing Ethanol? Start Here

Ethanol is a versatile and widely used alcohol found in everything from fuel to hand sanitizers. It's highly flammable, so careful storage is crucial. Whether you're managing a water-treatment facility, running a chemical plant, or operating a farm, understanding how to store ethanol safely can save you from potential hazards and ensure a long service life for your storage tanks.

Can you store it in a poly tank?

Yes, but with conditions. Ethanol can be stored in cross-linked polyethylene (XLPE) tanks, especially for fuel-grade and anhydrous ethanol. However, for higher concentrations like 99.5% ethanol, XLPE is preferred due to its resistance to stress-cracking. Standard HDPE tanks may not be suitable for prolonged exposure to anhydrous ethanol.

Key Issue: Flammability

Ethanol's primary concern is its flammability. With a low flash point, it requires careful handling to prevent fires. Ensure storage areas are equipped with proper ventilation and adhere to strict no-smoking and no-open-flame policies.

The safety that actually matters

• Use XLPE tanks for better resistance to ethanol's effects.
• Install tanks in well-ventilated areas to manage fumes.
• Follow grounding and bonding procedures during transfers.
• Ensure compliance with NFPA 30 for flammable liquids.

Common questions

Can I use a regular plastic tank for ethanol?

It's best to use XLPE tanks for ethanol, especially for higher concentrations, to prevent damage and leaks.

What precautions should I take when storing ethanol?

Ensure proper ventilation, follow grounding procedures, and keep away from ignition sources.

What type of gaskets should I use?

Match gaskets to the manufacturer chart to ensure compatibility with ethanol.
