First aid measures

Inhalation Remove victim to fresh air. Keep at rest in a position comfortable for breathing. Seek immediate medical

attention if needed.

Eye contact Rinse immediately with plenty of water, including under the eyelids, for at least 15 minutes. If irritation persists,

call a physician immediately.

Ingestion If ingested, do not induce vomiting. Drink plenty of water or milk immediately. If vomiting, continue to offer

water or milk. Never give anything by mouth to an unconscious person. Call a physician or poison control

center immediately and provide an estimate of when and how much material was ingested. Seek immediate

medical attention.

Skin Contact Wash with soap and water. If irritation, redness or swelling persists, call a physician immediately. Take off

contaminated clothing and wash before reuse.

Most important symptoms and effects, both acute and delayed

Symptoms Causes serious eye irritation. Causes skin irritation. May cause respiratory irritation. May cause an allergic

skin reaction.

Indication of any immediate medical attention and special treatment needed

Note to physicians Treat symptomatically.


Extinguishing Media

Suitable: Water spray, chemical foam, carbon dioxide (CO2), dry chemical

Unsuitable: Do not use water jet.

Specific hazards arising from the chemical

Flammable liquid and vapor. May polymerize on heating. Sealed containers may rupture explosively if hot.

Hazardous Combustion Products: Carbon oxides

Sensitivity to Static Discharge: Yes

Protective equipment and precautions for firefighters

A self-contained breathing apparatus and suitable protective clothing should be worn in fire conditions.


Personal precautions, protective equipment and emergency procedures

 Personal precautions:  Before cleaning any spill or leak, individuals must wear personal protective equipment as required.  Remove any contaminated clothing and wash thoroughly before reuse.

Environmental precautions:   ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Prevent product from entering drains. Spillages or uncontrolled discharges into watercourses must be alerted to the appropriate regulatory body.

Methods and material for containment and clean-up

Collect spillage. Do not adsorb onto sawdust or other combustible materials. Transfer to a

container for disposal or recovery. Use only non-sparking tools.



Precautions for safe handling

Do not eat, drink, or smoke at the work place. Wash thoroughly after handling. Avoid breathing

vapors. Use in a well-ventilated area. The vapor is heavier than air: beware of pits and confined

spaces. Ground container and receiving equipment. Use explosion proof electrical equipment. Use

only non-sparking tools. Take precautionary measure against static charge.


Storage Conditions

Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from heat,

sparks, open flame, hot surfaces – No smoking. Protect from sunlight. Methacrylate stored in bulk

quantities must be kept in contact with air (oxygen). Keep at temperature not exceeding 30°C/86

°F. Monomer vapors are uninhabited and may form polymers in vent or flame arresters, resulting

in blockage of vents.

Incompatible materials

Polymerization catalysts, such as peroxy or azo compounds, strong acids, alkalis and oxidizing

ACGIH = American Conference of Governmental Industrial Hygienists / OSHA = Occupational Safety and Health Administration

PEL = Permissible Exposure Levels / STEL – Short Term Exposure Limit / TLV – Threshold Limit Value / TWA = Time Weighted Average

Appropriate engineering controls Do not eat, drink or smoke at the work place. Provide adequate ventilation, including appropriate

local extraction, to ensure that the occupational exposure limit is not exceeded. Consideration

should be given to the work procedures involved and the potential extent of exposure as they may

determine whether a higher level of protection is required.

Engineering controls Apply technical measures to comply with the occupational exposure limits.

Individual protection measures, such as personal protective equipment

Eye / face protection Depending on the use of this product, safety glasses or goggles may be worn. If necessary, refer to

US OSHA 29CFR SS1910.133 or the appropriate standards of Canada or the EC member states.

Ensure that an eyewash station, sink or washbasin is available in case of exposure to eyes.

Skin and body protection If anticipated that prolonged and repeated skin contact will occur during use of this product, wear

gloves for routine use. If necessary, refer to US OSHA 29CFR SS1910.138 or the appropriate

standards of Canada or the EC member states. Wear suitable protective clothing.

Respiratory protection No special respiratory protection is required under typical circumstances of use or handling. If

necessary, use only respiratory protection authorized per US OSHA requirement in 29 CFR SS

1910.134, or applicable US state regulations, or the appropriate standards of Canada, its

provinces, or the EC member states. VENTILATION: Local exhaust at processing equipment.

General hygiene considerations Handle in accordance with good industrial hygiene and safety practice. Wash thoroughly after

handling. Food, beverages and tobacco products should not be carried, stored, or consumed

where this material is in use. Wash hands thoroughly before eating, drinking, or smoking.
