Storage & Handling

Recommended Storage
Keep tightly closed in a cool, well-ventilated flammables area away from ignition sources and oxidizers. Store locked up. Ground and bond containers.Adjudicated
Handling Precautions
Use chemical-resistant gloves and splash goggles. Bond and ground during transfer to prevent static accumulation. Eliminate ignition sources within vapor envelope.Class-level guidance — not product-specific; the SDS controls.
Incompatibilities
Strong oxidizing agents; strong acids.Adjudicated
Shelf Life
Consult Technical Services for product-specific shelf life

For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.

Packaging & Logistics

Shipping Description (US DOT)

UN1110, n-Amyl methyl ketone, 3, PG III

Packaging-dependent regulation: Non-bulk packaging (≤ 119 gal, e.g. drums, pails, cans) ships as NON-REGULATED under the combustible-liquid reclassification (49 CFR 173.150(f)). Bulk packaging (totes/IBC > 119 gal) ships fully regulated under the DOT profile shown above. The combustible-liquid reclassification does not apply to transportation by vessel or aircraft, except where other means of transportation is impracticable (49 CFR 173.120(b)(2)).

Sourced from 49 CFR 172.101. Confirm against shipping documents and carrier requirements before tender.
