1,3-Dichloropropene (Telone) Storage — RUP Soil Fumigant Tank Selection

Storing 1,3-Dichloropropene (Telone)? Stainless for Primary, Poly for Containment

Straight answer: Telone (1,3-dichloropropene) is a halogenated soil fumigant that attacks polyethylene over months — it's not a poly tank for primary storage. Commercial bulk storage uses 304L/316L stainless steel. Where poly does belong is the secondary-containment sump and berm underneath.

Can you store it in a poly tank? Not the product itself.

• Primary product storage: 304L or 316L stainless steel — the halogenated solvent degrades thermoplastics over multi-month exposure.
• Secondary containment: this is where an HDPE sump/berm is the right, cost-effective choice — short-contact spill capture, not long-term holding.

So poly has a real role here, just not as the primary tank. Gaskets/seals must suit halogenated solvents (PTFE/Viton); EPDM swells.

The safety that actually matters

• Restricted-use fumigant — licensed application, strict handling and PPE.
• Keep it in its rated steel system; use poly only for containment, never long-term product holding.

Common questions

Can I store Telone in a poly tank?

No for the product — it degrades polyethylene over months. Use 304L/316L stainless for primary storage; poly is for the secondary-containment sump.

Where does HDPE help?

As the containment berm/sump under a steel tank — short-contact spill capture.
