UN 1695 At a Glance
UN 1695 (Chloroacetone, stabilized) is listed as DOT Class 6 Toxic and is assigned to ERG Guide 131. Use this page to review placard data, common hazards, PPE notes, isolation context, first actions, and related UN numbers.
UN 1695 is Chloroacetone, stabilized, a flammable toxic lachrymator liquid assigned to ERG Guide 131. It combines vapor fire risk with severe eye and respiratory irritation.
Hazard overview: UN 1695 presents flammable vapor, flashback, toxic exposure and lachrymator hazards. Vapors can travel to ignition sources, and fire may produce corrosive toxic gases.
Response guidance: For a UN 1695 incident, responders should verify the product with shipping papers, package markings, SDS and ERG Guide 131. Establish incident command, isolate the area, stay upwind, prevent dust, vapor or aerosol exposure, control runoff and choose entry or cleanup actions based on monitoring, SDS and local SOP.
Firefighter training notes: Training for UN 1695 should emphasize toxic exposure routes, air monitoring, PPE selection, decontamination and preventing contaminated runoff. Use ERG 131, SDS and local SOP.
Regulatory context: Chloroacetone, stabilized is regulated as a hazardous material for transportation and emergency response purposes. Transportation, workplace exposure, spill reporting, waste handling, storage and environmental requirements may vary by formulation, concentration, quantity and jurisdiction. Verify current requirements through shipping papers, SDS, facility documents and applicable DOT, OSHA, EPA, NFPA, state or local authority guidance.
Storage & handling: Chloroacetone, stabilized should be stored in tightly closed compatible containers in a secure toxic-material area according to SDS and local hazardous materials procedures.
UN 1695 Quick Details
Common Hazards of UN 1695
- FLAMMABLE and toxic lachrymator liquid; vapors may ignite and form explosive mixtures with air.
- Vapors can cause severe eye tearing, respiratory irritation and skin injury.
- Vapors are heavier than air and may travel to ignition sources and flash back.
- Water contact may slowly decompose the material and spread contaminated runoff.
- Fire may produce irritating, corrosive and/or toxic gases.
- Containers may rupture or explode when heated.
- Runoff may carry toxic and irritating contamination.

PPE Requirements
Use positive-pressure SCBA for vapor, fire or confined-space exposure. Chemical-resistant gloves, eye/face protection and protective clothing should be selected from SDS because lachrymator effects and skin contact can be severe.
Isolation & Evacuation
First Actions for a UN 1695 Incident
- CALL 911. Then call the emergency response telephone number on the shipping paper, if available.
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Avoid breathing vapors, fumes, dust, mist, aerosol or smoke and avoid all skin or eye contact.
- Eliminate ignition sources if safe and keep vapors out of drains, sewers and low areas.
- Do not touch or walk through spilled material unless properly trained and wearing appropriate protective equipment.
- Avoid creating dust clouds or spreading contaminated liquid, powder, solution, runoff or debris.
- Ventilate closed spaces before entering, but only if properly trained, equipped, monitored and authorized by incident command.
- Isolate the spill or leak area and expand the perimeter if vapor, dust, aerosol, fire involvement or unknown concentration is present.
- Use ERG Guide 131, shipping papers, SDS, air monitoring and incident command for protective actions.
