Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: colorless liquid. Flash Point: 63 deg C.
Warning! Harmful if inhaled. May cause harm to the
unborn child. May cause eye, skin, and respiratory tract
irritation. Combustible liquid and vapor.
May be harmful if absorbed through the skin. May cause liver damage.
Hygroscopic (absorbs moisture from the air).
Target Organs: Liver, reproductive system.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be absorbed through the skin. If
absorbed, causes symptoms similar to those of ingestion. Not
expected to cause an allergic skin reaction.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause liver damage. May cause central nervous system
depression, characterized by excitement, followed by headache,
dizziness, drowsiness, and nausea. Advanced stages may cause
collapse, unconsciousness, coma and possible death due to
respiratory failure.
May cause auditory and visual hallucinations, disorientation,
sweating, and weakness.
Inhalation:
Causes respiratory tract irritation. May cause effects similar to
those described for ingestion. Inhalation at high concentrations may
cause CNS depression and asphixiation.
DMAC concentrations between 0 and 2 ppm, with occasional excursions
between 11 and 34 ppm, in a polymer manufacturing operation caused
dizziness, lethargy, and weakness.
Chronic:
Chronic ingestion may cause liver damage. May cause reproductive and
fetal effects.
Repeated dermal applications to dogs of DMAC at 4 mg/kg body weight
for 6 weeks produced extensive fatty infiltration of liver tissue.
Daily exposure of rats at 195 ppm DMAC for 6 months produced liver
damage.

Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
|
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Containers may explode
when heated. Combustible liquid and vapor. Vapors are heavier than
air and may travel to a source of ignition and flash back. Vapors can
spread along the ground and collect in low or confined areas.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide.
Flash Point: 63 deg C ( 145.40 deg F)
Autoignition Temperature: 335 deg C ( 635.00 deg F)
Explosion Limits, Lower:1.8 @ 100°C
Upper: 11.5 @ 160°C
NFPA Rating:
(estimated) Health: 2; Flammability: 2; Instability: 0
|
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Discard contaminated
shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or
expose empty containers to heat, sparks or open flames. Use only
with adequate ventilation. Keep away from heat and flame. Avoid
breathing vapor or mist. Destroy contaminated leather clothing.
Storage:
Keep away from sources of ignition. Do not store in direct sunlight.
Store in a tightly closed container. Keep under a nitrogen blanket.
Store in a cool, dry, well-ventilated area away from incompatible
substances.
|
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

Carcinogenicity:
CAS# 127-19-5:
Not listed by ACGIH, IARC, NTP, or CA Prop 65.
Epidemiology:
Jaundice was observed in workers as a result of repeated
exposures at 20 to 25 ppm DMAC, but appreciable skin
penetration undoubtedly contributed to this effect.
Teratogenicity:
Teratogenic effects from dermal application of DMAC were
reported in rats when DMAC was applied on gestation days
10 and 11 at a total dose of 2400 mg/kg body weight.
Reproductive Effects:
Adverse reproductive effects have occurred in experimental
animals.Some tests in adult animals have shown that DMAC
may cause changes to the testes only at levels which
produce other toxic effects in the adult animal.
Reproductive data on adult animals show no change in
reproductive performance.See actual entry in RTECS for
complete information.
Mutagenicity:
See actual entry in RTECS for complete information.
Neurotoxicity:
