Description of first aid measures
If inhaledMove the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms and effects, both acute and delayed
May be harmful if inhaled; may cause dizziness or suffocation. Irritating to skin and eyes. Harmful if swallowed. (USCG, 1999)
Indication of any immediate medical attention and special treatment needed
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Esters and related compounds
Extinguishing media
If material on fire or involved in fire: Use water in flooding quantities as fog. Do not extinguish fire unless flow can be stopped. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. Isobutyl methacrylate, stabilized
Specific Hazards Arising from the Chemical
Special Hazards of Combustion Products: Thermal decomposition may yield oxides of carbon. Behavior in Fire: Combustible liquid. Sealed containers may rupture explosively when exposed to heat, due to polymerization. (USCG, 1999)
Advice for firefighters
Wear self-contained breathing apparatus for firefighting if necessary.
NFPA 704
| HEALTH | 2 | Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury (e.g. diethyl ether, ammonium phosphate, iodine) | |
| FIRE | 2 | Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur) | |
| REACT | 2 | Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water (e.g. white phosphorus, potassium, sodium) | |
| SPEC. HAZ. |
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Temp during storage must be kept low to minimize formation of peroxides and other oxidation products. ... Storage temp below 30 deg C are recommended for i-Butylmethacrylate. The methacrylate monomer should not be stored for longer than one year. Isobutyl methacrylate is sensitive to UV light and should, therefore, be stored in the dark. The methacrylic ester may be stored in mild steel, stainless steel, or aluminum.

Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Chemical stability

Possibility of hazardous reactions
Flammable when exposed to heat or flame.ISOBUTYL METHACRYLATE is an acrlate ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This compound polymerizes readily. (NTP, 1992)

Persistence and degradability
AEROBIC: In the modified Japanese MITI test, isobutyl methacrylate reached 33% of its Theoretical BOD after 28 days(1).
Bioaccumulative potential
An estimated BCF of 26 was calculated in fish for isobutyl methacrylate(SRC), using a log Kow of 2.66(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of isobutyl methacrylate has been reported as 1480-3920(1). According to a classification scheme(2), these Koc values suggest that isobutyl methacrylate is expected to have low to slight mobility in soil.
Other adverse effects
