Adverse Effects：
Asthma - Reversible bronchoconstriction (narrowing of bronchioles) initiated by the inhalation of irritating or allergenic agents.
Cleanup Methods：
1. Remove all ignition sources. 2. Ventilate area of spill or leak. 3. For small quantities, absorb on paper towels. Evaporate in a safe place (such as a fume hood). Allow sufficient time for evaporating vapors to completely clear the hood ductwork. Burn the paper in a suitable location away from combustible materials. Large quantities can be reclaimed or collected and atomized in a suitable combustion chamber equipped with an appropriate effluent gas cleaning device. Diethylaminoethanol should not be allowed to enter a confined space, such as a sewer, because of the possibility of an explosion. Sewers designed to preclude the formation of explosive concentrations of diethylaminoethanol vapors are permitted.

Disposal Methods：
Drain into the sewer with abundant water. (a) Dissolve in a combustible solvent such as alcohols, etc. Burn in an open furnace by igniting from a safe distance with the utmost care or sprinkle into the fire chamber of the furnace with afterburner and scrubber. (b) Pour into sodium bisulfate in a large evaporating dish. Sprinkle water and neutralize. Drain into the sewer with sufficient water.

First Aid Measures：
Ingestion First Aid: Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .
Reactivity Profile：
2-DIETHYLAMINOETHANOL is an organic compound with both amine and alcohol substituents. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. 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. This compound can react with strong oxidizers and acids. (NTP, 1992)
Signs and Symptoms：
irritation eyes, skin, respiratory system; nausea, vomiting
Ingestion Prevention：
Do not eat, drink, or smoke during work.
Medical Surveillance：
Employees should be screened for history of certain medical conditions which might place the employee at increased risk from diethylaminoethanol exposure. /These are/ chronic respiratory disease ... skin disease ... /and/ eye disease. ... Any employee developing the above-listed conditions should be referred for further medical examination.
Inhalation Prevention：
Use ventilation, local exhaust or breathing protection.
Nonfire Spill Response：
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, 2024)
Air and Water Reactions：
Flammable. Soluble in water. This chemical is sensitive to moisture. Slowly hydrolyzes.
Human Toxicity Excerpts：
On March 23, 1981, the National Institute for Occupational Safety and Health (NIOSH) received a request for a Health Hazard Evaluation from Boehring Ingelheim, Ltd, Ridgefield, Connecticut. The request stated that approximately 15 employees in the office support area of a production building had been experiencing rashes since the beginning of March 1981. Environmental samplinq did not reveal any diethylaminoethanol in air samples. However, results of sampling suggested the presence of a conjugated amine which possesses acidic properties. The specific agent could not be identified. Skin examinations revealed an irritant-type rash on the exposed areas of the face neck and hands. The distribution of the rash was consistent with and suggestive of a phototoxic skin reaction. Both the environ...
Fire Fighting Procedures：
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use "alcohol" foam, carbon dioxide or dry chemical.
Isolation and Evacuation：
Evacuation: ERG2024, Guide 132 (2-Diethylaminoethanol): · If tank, rail tank car or highway tank 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.
