METHYL METHACRYLATE, INHIBITED

CAS: 80-62-6

Fraction By Weight: 100.0%

Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, vomiting, headache, drowsiness, symptoms of
drunkenness, lung congestion, kidney damage, liver damage LONG TERM
EXPOSURE: difficulty breathing, liver damage SKIN CONTACT: SHORT
TERM EXPOSURE: irritation (possibly severe), allergic reactions,
rash LONG TERM EXPOSURE: same as effects reported in short term
exposure EYE CONTACT: SHORT TERM EXPOSURE: irritation (possibly
severe), tearing, eye damage LONG TERM EXPOSURE: no information on
significant adverse effects INGESTION: SHORT TERM EXPOSURE:
allergic reactions, nausea, vomiting, drowsiness, symptoms of
drunkenness, coma LONG TERM EXPOSURE: no information on significant
adverse effects
Medical Cond Aggravated by Exposure:

First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
Get immediate medical attention. SKIN CONTACT: Wash skin with soap
and water for at least 15 minutes while removing contaminated
clothing and shoes. Get medical attention, if needed. Thoroughly
clean and dry contaminated clothing and shoes before reuse. EYE
CONTACT: Flush eyes with plenty of water for at least 15 minutes.
Then get immediate medical attention. INGESTION: Contact local
poison control center or physician immediately. Never make an
unconscious person vomit or drink fluids. When vomiting occurs,
keep head lower than hips to help prevent aspiration. If person is
unconscious, turn head to side. Get medical attention immediately.
NOTE TO PHYSICIAN: For ingestion, consider gastric lavage and
activated charcoal slurry.

Flash Point:50 F (10 C) (OC)
Autoignition Temp:790 F (421 C)
Lower Limits:1.7%
Upper Limits:8.2%
Extinguishing Media:alcohol resistant foam, carbon dioxide, regular dry
chemical, water Large fires: Use alcohol-resistant foam or flood
with fine water spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Cool containers with water spray until well
after the fire is out. Stay away from the ends of tanks. For fires
in cargo or storage area: Cool containers with water from unmanned
hose holder or monitor nozzles until well after fire is out. If
this is impossible then take the following precautions: Keep
unnecessary people away, isolate hazard area and deny entry. Let
the fire burn. Withdraw immediately in case of rising sound from
venting safety device or any discoloration of tanks due to fire.
For tank, rail car or tank truck: Evacuation radius: 800 meters
(1/2 mile). Water may be ineffective.
Unusual Fire/Explosion Hazard:Severe fire hazard. Moderate explosion
hazard. Vapor/air mixtures are explosive above flash point. The
vapor is heavier than air. Vapors or gases may ignite at distant
ignition sources and flash back. Containers may rupture or explode
if exposed to heat.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Protect from physical
damage. Store outside or in a detached building. Store with
flammable liquids. Keep separated from incompatible substances.
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 1000 ppm Any
supplied-air respirator. Any chemical cartridge respirator with a
full facepiece and organic vapor cartridge(s). Any air-purifying
respirator with a full facepiece and an organic vapor canister. Any
powered, air-purifying respirator with organic vapor cartridge(s).
Any self-contained breathing apparatus with a full facepiece. Any
supplied-air respirator with a full facepiece. Escape - Any
air-purifying respirator with a full facepiece and an organic vapor
canister. Any appropriate escape-type, self-contained breathing
apparatus. For Unknown Concentrations or Immediately Dangerous to
Life or Health - Any supplied-air respirator with full facepiece
and operated in a pressure-demand or other positive-pressure mode
in combination with a separate escape supply. Any self-contained
breathing apparatus with a full facepiece.
Ventilation:Provide local exhaust or process enclosure ventilation
system. Ensure compliance with applicable exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles with a faceshield.
Provide an emergency eye wash fountain and quick drench shower in
the immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
