Safety Highlights

DMF is a flammable and toxic solvent associated with reproductive toxicity and acute inhalation and dermal hazards. It requires strict handling procedures and use of personal protective equipment (PPE) to avoid exposure.

Flammable Liquid

Flash point at 58°C. Vapors may form explosive mixtures with air. Keep away from heat, sparks, and flames.

Toxic on Contact

Harmful if inhaled or absorbed through the skin. May cause gastrointestinal distress, fatigue, or dizziness.

Corrosive Agent

Causes serious eye irritation. May damage the unborn child. Restricted to professional use only.

Emergency Measures

In case of fire, use CO₂, alcohol-resistant foam, dry powder, or water spray. Avoid water jets. Evacuate area and wear full protective gear with respirator.

Proper Storage

Store tightly sealed in a cool, ventilated flammable storage area. Keep away from heat, oxidizers, halogens, and ignition sources.

Regulatory ID

UN No: UN2265 | DOT/ADR Hazard Class: 3 (Flammable) | Packaging Group: III | SVHC Classification: Reproductive Toxicant – Category 1B

Environmental Care

Readily biodegradable but toxic to aquatic organisms in high concentrations. Do not release into drains or soil.

PPE Required

Use butyl rubber or Viton® gloves, chemical splash goggles, protective clothing, and A-type organic vapor respirator.
