General Description
Colorless liquid with a musky ammonia odor. Less dense than water. (USCG, 1999)

Hazards

Reactivity Alerts
Air & Water Reactions
Highly flammable. Water soluble.
Fire Hazard
Behavior in Fire: Dangerous when exposed to heat or flame. Can react vigorously with oxidizing materials. (USCG, 1999)
Health Hazard
Inhalation of high concentration of vapor will will produce irritation of the respiratory tract and lungs. Inhalation of large quantities of vapor may be fatal. (USCG, 1999)
Reactivity Profile
DIMETHYLCYCLOHEXYLAMINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Use caution: Liquids with this reactive group classification have been known to react with the absorbent listed below.

Response Recommendations

Isolation and Evacuation
Excerpt from 132 Polymerizable warning [Flammable Liquids - Corrosive]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)
Firefighting
Fire Extinguishing Agents: Carbon dioxide, dry chemical powder, polymer or alcohol foam. (USCG, 1999)
Non-Fire Response
Excerpt from 132 Polymerizable warning [Flammable Liquids - Corrosive]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. Absorb with earth, sand or other non-combustible material. For hydrazine, absorb with DRY sand or inert absorbent (vermiculite or absorbent pads). Use clean, non-sparking tools to collect absorbed material.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2020)
Protective Clothing
Wear self-contained breathing apparatus, rubber boots, heavy rubber gloves. If entering spill area, wear self-contained breathing apparatus and full protective clothing, including boots. (USCG, 1999)

First Aid
Get medical attention.

INHALATION: Remove from exposure area. If the victim has trouble breathing, give oxygen. If breathing has stopped, give articial respiration.

EYES: Flush eyes with water for at least 15 minutes.

SKIN: Remove contaminated clothing. Flush affected areas with plenty of running water. (USCG, 1999)
