UN 2413 — Tetrapropyl orthotitanate
Placard: Flammable. ERG Guide 128. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2413 At a Glance
UN 2413 (Tetrapropyl orthotitanate) is listed as DOT Class 3 Flammable and is assigned to ERG Guide 128. Use this page to review placard data, common hazards, PPE notes, isolation context, first actions, and related UN numbers.
UN 2413 is Tetrapropyl orthotitanate, a flammable moisture-sensitive titanate assigned to ERG Guide 128. Water can hydrolyze it while vapors create flashback hazards.
Hazard overview: FLAMMABLE moisture-sensitive titanium alkoxide liquid; vapors may ignite and form explosive mixtures with air. Hydrolyzes with water or moisture, producing alcohol and titanium-containing solids. Vapors are heavier than air and may travel to ignition sources and flash back.
Response guidance: For UN 2413, isolate the area, eliminate ignition sources, keep vapors out of drains and use SCBA in vapor or fire conditions. Cool containers from a protected distance and choose foam, dry chemical or CO2 using SDS and ERG 128.
Firefighter training notes: Training for UN 2413 should emphasize moisture reaction, corrosive fuming or hydrolysis, flammable vapor control, PPE selection, runoff containment and decontamination. Use ERG 128, SDS and local SOP.
Regulatory context: Tetrapropyl orthotitanate is regulated as a hazardous material for transport and emergency response. Storage, exposure, spill reporting, waste and fire-code duties depend on quantity, concentration and jurisdiction; verify shipping papers, SDS and local authority requirements.
Storage & handling: Tetrapropyl orthotitanate should be stored in approved flammable-liquid containers with moisture control, ventilation, spill containment and separation from heat, ignition sources, oxidizers and incompatible materials.

PPE Requirements
Use positive-pressure SCBA for vapor, fire or confined-space exposure. Wear chemical-resistant gloves, eye/face protection and flame-resistant protection as appropriate.
Isolation & Evacuation
First Actions for a UN 2413 Incident
- Call 911 and the emergency response number on the shipping paper, if available.
- Keep unauthorized personnel away and establish incident command.
- Stay upwind, uphill and upstream; keep responders out of low vapor areas.
- Eliminate ignition sources if this can be done safely.
- Avoid breathing vapor, mist or smoke and avoid skin or eye contact.
- Keep water contact controlled because moisture can increase decomposition, heat or corrosive fuming.
- Do not touch damaged containers or spilled material without proper training and PPE.
- Ventilate confined spaces only after monitoring and only if properly trained and equipped.
- Use ERG Guide 128, SDS, shipping papers and air monitoring to set isolation, evacuation and entry decisions.
