LD50 LC50 Mixture:NO DATA PROVIDED BY RESPONSIBLE PARTY.
Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:PRIMARY ROUTES OF EXPOSURE ARE
INHALATION AND SKIN CONTACT. SUSCEPTIBLE PERSONS WITH KNOWN
ALLERGIES TO METHACRYLATES & ACRYLATES MAY DEVELOP ALLERGIC
RESPONSE. INHALATION: HIGH VAPOR CONCENTRATION CA N INDUCE
HEADACHE, NAUSEA, SMARTING OF EYES & IRRITATION OF RESPIRATORY
SYSTEM. EYES: LIQUID CONTACT WILL CAUSE IRRITATION AND POSSIBLE
CORNEAL DAMAGE. SKIN: MATERIAL MAY CAUSE SENSITIZATION BY SKIN C
ONTACT. REPEATED AND/OR PROLONGED CONTACT MAY CAUSE DERMATITIS.
INGESTION: LOW ORAL TOXICITY BUT INGESTION MAY CAUSE IRRITATION OF
THE GASTROINTESTINAL TRACT.
Explanation of Carcinogenicity:NO DATA PROVIDED BY RESPONSIBLE PARTY.
Effects of Overexposure:SKIN: DERMAL REDNESS OR IRRITATION. EYE
CONTACT:L IRRITATION AND REDNESS. INAHALTION: HIGH VAPOR
CONCENTRATIONS CAN INDUCE HEADACHE, NAUSEA, SMARTING OF EYES AND
IRRITATION OF RESPIRATORY SYSTEM.
Medical Cond Aggravated by Exposure:OPEN SORES AND WOUNDS OF THE SKIN.
SUSCEPTIBLE PERSONS WITH KNOWN ALLERGIES TO METHACRYLATES AND
ACRYLATES MAY DEVELOP ALLERGIC RESPONSE.

First Aid:INHALATION: MOVE SUBJECT TO FRESH AIR. GIVE ARTIFICIAL
RESPIRATION IF BREATHING HAS STOPPED. INGESTION: IF SWALLOWED AND
CONSCIOUS, GIVE 2 GLASSES OF WATER TO DRINK AND CONSULT A PHYSICIAN
IMMEDIATELY . EYES: FLUSH EYES PROMPTLY WITH COPIOUS AMOUNTS OF
WATER FOR 15 MINUTES AND CONSULT PHYSICIAN IF IRRITATION IS
APPARENT. SKIN CONTACT: WASH SKIN WITH SOAP & WATER. SEE PHYSICIAN
IF IRRITATION PERSIST S.

Flash Point Method:TOC
Flash Point:=12.8C, 55.F
Lower Limits:2.1
Upper Limits:12.5
Extinguishing Media:ALCOHOL FOAM, CARBON DIOXIDE, DRY CHEMICAL AND
WATER SPRAY.
Fire Fighting Procedures:WATER MAY BE INEFFECTIVE UNLESS USED AS A FINE
SPRAY OF FOG. EXPLOSION HAZARD. USE WATER SPRAY TO COOL
FIRE-EXPOSED CONTAINERS OF METHYL METHACRYLATE.
Unusual Fire/Explosion Hazard:VAPORS MAY TRAVEL TO SOURCE OF IGNITION
AND FLASH BACK. AVOID IGNITION SOURCES OR EXCESSIVE TEMPERATURES.
HEAT CAN INDUCE POLYMERIZATION WITH RAID RELEASE OF ENERGY. HEATED
CONTAINERS MAY RUPTURE EXPL OSIVELY.

Spill Release Procedures:ELIMINATE IGNITION SOURCES. AVOID BREATHING
VAPORS, DIKE & ABSORB SPILL WITH INERT MATERIAL (SAND, SODA ASH,
VERMICULITE, ETC.) AND TRANSFER TO CONTAINERS FOR DISPOSAL.; USE
NON-SPARKING TOOLS. CONTAM INATED MONOMER MAY BE UNSTABLE, ADDITION
OF INHIBITOR WILL PREVENT POLYMERIZATION. REMOVE SATURATED CLOTHES
& WASH AFFECTED SKIN WITH SOAP & WATER.
Neutralizing Agent:NO DATA PROVIDED BY RESPONSIBLE PARTY.

Handling and Storage Precautions:DO NOT BREATH VAPORS OR MIST. DO NOT
GET IN EYES, ON SKIN OR CLOTHES.CLOSE CONTAINER AFTER EACH
USE.STORE AT AMBIENT TEMPERATURES OUT OF DIRECT SUNLIGHT.ADVISABLE
TO USE OLDEST MATERIAL FIRST.USE ADEQ UATE VENTILATION.DO NOT STORE
UNDER O2-FREE ENVIRONMENT.
Other Precautions:VAPORS ARE UNIHIBITED & MAY FORM POLYMERS IN VENTS OR
FLAME ARRESTORS, RESULTING IN BLOCKED VENTS. KEEP AWAY FROM SPARKS
& OPEN FLAME. KEEP CONTAINER IN A COOL PLACE. DO NOT EXPOSE TO
DIRECT SUNLIGHT. STORE IN A WELL-VENTILATED PLACE. KEEP CONTAINER
TIGHTLY CLOSED. STORE IN ACCORDANCE WITH NFPA RECO MMENDATIONS.

Respiratory Protection:NONE IS REQUIRED IF AIRBORNE CONCENTRATION IS
MAINTAINED BELOW TLV.FOR AIRBORNE CONCENTRATIONS UP TO 10 TIMES THE
TLV, WEAR A NIOSH APPROVED HALF MASK,AIR PURIFYING
RESPIRATOR(ORGANIC VAPOR CARTRIDGE) . (SEE SUPPLEMENTAL).
Ventilation:USE VENTILATION ADEQUATE TO KEEP EMPLOYEE EXPOSURE BELOW
EXPOSURE LIMITS. MECHANICAL VENTILATION SHOULD HAVE EXPLOSION-PROOF
MOTORS.
Protective Gloves:IMPERVIIOUS GLOVES: NITRILE IS BETTER THAN PVC (BUTYL
RUBBER PREFERRED).
Eye Protection:SPLASH-PROOF GOGGLES (ANSI Z87.1 OR APPROVED
EQUIVALENT).
Other Protective Equipment:USE CHEMICALLY RESISTANT APRON AND OVERSHOES
TO AVOID PROLONGED OR REPEATED SKIN CONTACT.
Work Hygienic Practices:OBSERVE NORMAL CARE WHEN WORKING WITH
CHEMICALS. WASH THOROUGHLY AFTER HANDLING.
Supplemental Safety and Health
FOR AIRBORNE CONCENTRATIONS UP TO 100 TIMES THE TLV WEAR A MSHA/NIOSH
APPROVED FULL FACEPIECE AIRLINE RESPIRATOR W/EMERGENCY ESCAPE
PROVISIONS. FOR UNKNOWN CONENTRATIONS WEAR SELF-CONTAINED BREATHING
APPARATUS IN THE POSITIVE PRESSURE MODE.
