ETHYLETHANAMINE
IDENTIFICATION:
CAS:
109-89-7
DOT ID:
UN1154
Hazard class or Division:
3 (FLAMMABLE LIQUID)
ERG Guide:
132
Formula:
C4H11N
RTECS No:
HZ8750000
Properties:
Highly
flammable watery liquid. Colorless. Fishy, ammonia odor. Floats on and mixes
with water; flammable, irritating vapor is produced. Vapors are heavier than
air; will collect in low areas.
Uses:
A corrosion inhibitor in
iron, steel, and metal industries; a solvent for metal coatings, adhesives,
fats, gums, oils, bitumens, resins, lacquers, waxes; degreasing of metals;
electroplating.
HEALTH & SAFETY INFORMATION
• IDLH:
200
ppm/608 mg/m3
•
Odor threshold:
0.06–42.56 mg/m3
•
OSHA Table Z-1 Air Contaminant
•
Moderately toxic by all routes of exposure. Vapor can cause irritation and
burning of eyes, skin, and respiratory system. High concentration of vapor can
cause asphyxiation. Inhalation may cause lung edema; the effects may be
delayed. Corrosive. Contact with liquid can cause severe irritation to the skin
with possible cellular or tissue death (necrosis) and eye damage including
possible blindness.
Exposure Limits:
•
ACGIH TLV: 5 ppm/15 mg/m3 TWA; 15 ppm/45 mg/m3 STEL
•
OSHA PEL: 25 ppm/75 mg/m3 TWA
•
NIOSH REL: 10 ppm/30 mg/m3 TWA; 25 ppm/75 mg/m3 STEL

SA:CF (any supplied-air
respirator operated in a continuous-flow mode) PAPRS [any powered,
air-purifying respirator with cartridge(s) providing protection against the
compound of concern] CCRFS [any chemical cartridge respirator with a full
facepiece and cartridge(s) providing protection against the compound of
concern] GMFS [any air-purifying, full-facepiece respirator (gas mask) with a
chin-style, front- or back-mounted canister providing protection against the
compound of concern] SCBAF (any self-contained breathing apparatus with a full
facepiece) SAF (any suppliedair respirator with a full facepiece).
Emergency or Planned Entry into
Unknown Concentrations or IDLH Conditions
SCBAF:PD,PP (any self-contained breathing apparatus that has a
full facepiece and is operated in a pressure-demand or other positivepressure
mode) SAF:PD,PP:ASCBA (any suppliedair respirator that has a full facepiece and
is operated in a pressure-demand or other positive-pressure mode in combination
with an auxiliary self-contained breathing apparatus operated in a
pressure-demand or other positive-pressure mode.
Escape:
GMFS [any airpurifying, full-facepiece
respirator (gas mask) with a chin-style, front- or back-mounted canister
providing protection against the compound of concern] SCBAE (any appropriate
escape-type, self-contained breathing apparatus).
Note:
Substance causes eye irritation or damage;
eye protection needed.
Reactivity:
Forms
explosive mixture with air. May accumulate static electrical charges, and may
cause ignition of its vapors. Violent reaction with oxidizers. Incompatible
with acids, organic anhydrides, isocyanates, vinyl acetate, acrylates,
substituted allyls, alkylene oxides, epichlorohydrin, ketones, aldehydes,
alcohols, glycols, mercury, phenols, cresols, caprolactum solution, and strong
oxidizers. Attacks aluminum, copper, lead, tin, zinc, and alloys.
FIRE INFORMATION
Fire
fighting gear, including SCBA, does not provide adequate protection. If
exposure occurs, remove and isolate gear immediately and thoroughly
decontaminate personnel. Vapors may travel long distances to sources of
ignition and flash back. Vapor in confined areas or containers may explode in
fire. If material or contaminated runoff enters waterways, notify downstream
users of potentially contaminated water.

FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Do not use mouth-to-mouth method if victim
swallowed or inhaled the substance; induce artificial respiration with the aid
of a pocket mask equipped with a one-way valve or other proper respiratory
medical device. Administer oxygen if breathing is difficult. Remove and isolate
contaminated clothing and shoes. In case of contact with substance, immediately
flush skin or eyes with running water for at least 20 minutes. Keep victim warm
and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to
substances may be delayed. Ensure that medical personnel are aware of the
material(s) involved, and take precautions to protect themselves.
