Emergency overview:
Warning!
Flammable. Irritant. Sensitizer. Lachrymator. Irritating to eyes, respiratory
system, and skin. This material may be susceptible to autooxidation. This
material may be peroxidzable, which may cause hazardous polymerization.
Appearance: Colorless liquid
Flash Point: 48.2°F (Closed Cup)
Target Organs: eyes, skin, nervous system, respiratory system,
liver, kidneys.
Potential Health Effects
Eye: Causes eye irritation. Lachrymator.
Skin: Causes irritation. May cause sensitization. May be absorbed
through the skin.
Ingestion: Harmful if swallowed. May cause gastrointestinal irritation
accompanied with nausea, diarrhea, and vomiting. May cause
central nervous system depression, liver damage and kidney damage.
Inhalation: Causes respiratory tract irritation. Symptoms of overexposure
may include coughing, chest pain, central nervous system depression,
nausea, headache, drowsiness, irritability and narcosis. High
levels may cause pulmonary edema and difficulty breathing.
Chronic: Prolonged inhalation may cause respiratory tract inflammation
and lung damage. Repeated exposure may cause tingling or
prickling sensation of the skin.
Aggravation of Pre-existing Conditions:
Persons with impaired liver, kidney, respiratory function, or
with pre-existing skin or eye disorders may be more susceptible
to the effects of this substance.
Eyes: In case of eye contact, immediately flush eyes with copious amounts of water for at least 15 minutes, lifting upper and lower eyelids open. Seek medical attention. Skin: In case of skin contact, flush skin with plenty of soap and water for at least 15 minutes. Remove contaminated clothing and wash before reuse. Remove contaminated shoes and thoroughly clean before reuse. Seek medical attention if symptoms occur. Ingestion: If swallowed, wash out mouth with water, provided person is conscious. Seek immediate medical attention. Do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek medical attention. Notes to Physician: Treat symptomatically and supportively. After vomiting, have victim drink a mixture of 2 tablespoonfuls of activated charcoal and 8 ounces of water.
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Will burn if involved in a fire. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Flammable 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: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. For large fires, use water spray, fog, or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Water may be ineffective. Do NOT use straight streams of water.
General Information: Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate protective equipment as indicated in section 8. Spills/Leaks: Contain and recover liquid if possible. Absorb spill with inert material such as vermiculite, sand or earth. Scoop up with nonsparking tool and place in suitable container for disposal. Avoid runoff into storm sewers and ditches which lead to waterways. Wash spill site after pickup is complete.
Handling: Avoid breathing vapor. Avoid contact with eyes, skin and clothing. Avoid prolonged or repeated exposure. Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Storage: Keep away from sources of ignition. Store refrigerated, below 4°C/39°F. Keep container tightly closed. Keep from contact with oxidizing materials. May form peroxides, which may initiate exothermic polymerization. An air space is required above the liquid in all containers; avoid storage under an oxygen-free atmosphere.
Engineering Controls: A safety shower and eyewash facility must be readily available. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits. Use nonsparking tools. Use only in a chemical fume hood. Exposure Limits: Chemical Name ACGIH NIOSH OSHA - Final PELs Methyl methacrylate 50ppm TWA 100 ppm TWA 100 ppm TWA 100 ppm STEL 410vmg/m3 TWA 410 mg/m3 TWA 1000 ppm IDHL OSHA Vacated PELs: Methyl methacrylate: 100 ppm TWA; 410 mg/m3 TWA Personal Protective Equipment Eyes: Wear chemical splash goggles and/or a full face shield where splashing is possible. Skin: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls as appropriate, to prevent skin contact. Respirators: If exposure limits are exceeded or if irritation or other symptoms are experienced, follow OSHA respirator regulations found on 29 CFR 1910.134; use a NIOSH/MSHA or European Standard En149 approved respirator.
Physical State: liquid Appearance: clear, colorless Odor: sharp, irritating pH: Not available Vapor Pressure: 29 mm Hg at 20°C Vapor Density: 3.5 (air=1) Evaporation Rate: 3.1 (Butyl acetate = 1) Viscosity: .06 at 20°C Boiling Point: 100.5 °C Freezing/Melting Point: -48 °C Autoignition Temperature: 421 °C Flash Point: 2 °C Decomposition Temperature: Not available Explosion Limits Lower: 2.1% Upper: 12.5% Solubility in water: 1.5g/100 ml at 20 °C Specific Gravity/Density: 0.944 (water=1) Molecular Formula: CH2·C(CH3)COOCH3 Molecular Weight: 100.12
Chemical Stability: Inhibited monomer. The presence of oxygen is required for the inhibitor to work effectively. May polymerize under certain conditions if the stabilizer is lost. Storage hazard; forms peroxides with hay initiate exothermic polymerization. May undergo autopolymerization. May form peroxides that can initiate explosive polymerization of the bulk monomer. Vapor may polymerize explosively. Conditions to Avoid: Light, ignition sources, exposure to air, excess heat, loss of inhibitor, confined spaces, contamination, ionizing radiation, oxygen-free atmospheres, oxygen depletion. Incompatibility with Other Materials: Strong oxidizing agents, strong acids, strong bases, amines, halogens, catalytic metals, polymerization catalysts. Hazardous Decomposition of Products: Carbon monoxide, Carbon dioxide Hazardous Polymerization: May occur
