A clear colorless liquid with a "fishlike" odor. Denser than water. Flash point 199°F. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion.
Air & Water Reactions
Soluble in water.
Special Hazards of Combustion Products: Toxic oxides of nitrogen may be formed in fire. (USCG, 1999)
Inhalation of hot vapors can irritate nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes causes irritation. Repeated and prolonged skin contact produces a mild, transient irritation. (USCG, 1999)
This amine is a very mild chemical base. It does tend to neutralize acids to form salts plus water. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Isolation and Evacuation
Excerpt from ERG Guide 128
[Flammable Liquids (Water-Immiscible)]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet).
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)
Excerpt from ERG Guide 128
[Flammable Liquids (Water-Immiscible)]:
CAUTION: The majority of these products have a very low flash point. Use of water spray when fighting fire may be inefficient. CAUTION: For mixtures containing alcohol or polar solvent, alcohol-resistant foam may be more effective.
SMALL FIRE: Dry chemical, CO2, water spray or regular foam.
LARGE FIRE: Water spray, fog or regular foam. Avoid aiming straight or solid streams directly onto the product. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. For petroleum crude oil, do not spray water directly into a breached tank car. This can lead to a dangerous boil over. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2020)
SMALL SPILLS AND LEAKAGE: If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
STORAGE PRECAUTIONS: You should store this material in a refrigerator. (NTP, 1992)
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary.

The fabric permeation data was generated for DuPont by a third party
laboratory. Permeation data for industrial chemicals is obtained per
ASTM F739. Normalized breakthrough times (the time at which the
permeation rate exceeds 0.1 μg/cm2/min) are reported in minutes. All
chemicals have been tested between approximately 20°C and 27°C unless
otherwise stated. All chemicals have been tested at a concentration of
greater than 95% unless otherwise stated.
Chemical warfare agents (Lewisite, Sarin, Soman, Sulfur Mustard, Tabun
and VX Nerve Agent) have been tested at 22°C and 50% relative humidity
per military standard MIL-STD-282. "Breakthrough time" for chemical
warfare agents is defined as the time when the cumulative mass which
permeated through the fabric exceeds the limit in MIL-STD-282 [either
1.25 or 4.0 μg/cm2].
A Caution from DuPont
This information is based upon technical data that DuPont believes to
be reliable on the date issued. It is subject to revision as additional
knowledge and experience are gained. The information reflects
laboratory performance of fabrics, not complete garments, under
controlled conditions. It is intended for informational use by persons
having technical skill for evaluation under their specific end-use
conditions, at their own discretion and risk. It is the user's
responsibility to determine the level of toxicity and the proper
personal protective equipment needed. Anyone intending to use this
information should first verify that the garment selected is suitable
for the intended use. In many cases, seams and closures have shorter
breakthrough times and higher permeation rates than the fabric. If
fabric becomes torn,abraded or punctured, or if seams or closures fail,
or if attached gloves, visors, etc. are damaged, end user should
discontinue use of garment to avoid potential exposure to chemical.
Since conditions of use are outside our control, DuPont makes no
warranties, express or implied, including, without limitation, no
warranties of merchantability or fitness for a particular use and
assume no liability in connection with any use of this information.

Special Warning from DuPont: Tychem® and Tyvek® fabrics should not be
used around heat, flames, sparks or in potentially flammable or
explosive environments. Only...
...Tychem® ThermoPro, Tychem® Reflector® and Tychem® TK styles 600T/601T
(with aluminized outer suit) garments are designed and tested to help
reduce burn injury during escape from a flash fire. Users of Tychem®
ThermoPro, Tychem® Reflector® and Tychem® TK styles 600T/601T (with
aluminized outer suit) garments should not knowingly enter an explosive
environment. Tychem® garments with attached socks must be worn inside
protective outer footwear and are not suitable as outer footwear. These
attached socks do not have adequate durability or slip resistance to be
worn as the outer foot covering.
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.
INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
