4.1. Description of first aid measures
First aider needs to protect himself. Take off all contaminated clothing immediately.Medical treatment is necessary if symptoms occur which are obviously caused by skin or eye contact with the product or by inhalation of its vapours.
Move subject to fresh air and keep him calm. See a physician.
Wash off immediately with soap and water. If skin irritation occurs consult a physician.
Keeping the eyelids apart flush thoroughly with water immediately. If irritation persists, contact a physician.
Do not induce vomiting. Call a physician immediately.
4.2. Most important symptoms and effects, both acute and delayed
Headache, confusion, Skin Sensitisation, Causes skin and eye irritation.
4.3. Indication of any immediate medical attention and special treatment needed
5.1. Extinguishing media
Suitable extinguishing media
foam, dry chemical, carbon dioxide
Extinguishing media which must not be used for safety reasons
High volume water jet
5.2. Special hazards arising from the substance or mixture
May be released in case of fire: carbon monoxide, carbon dioxide, organic products of decomposition.
5.3. Advice for firefighters
Wear self-contained breathing apparatus.
6.1. Personal precautions, protective equipment and emergency procedures
Assure sufficient ventilation. Use personal protective clothing. Keep away sources of ignition. Use breathing apparatus if exposed to vapours/dust/mist/aerosol.
6.2. Environmental precautions
Prevent product from getting into drains/surface water/groundwater.
6.3. Methods and material for containment and cleaning up
Larger quantities: Remove mechanically (by pumping). Use explosion-proof equipment! Smaller quantities and/or residues: Contain with absorbent material (e.g. sand, diatomaceous earth, acid absorbent, universal absorbent or sawdust). Dispose of in accordance with regulations.
6.4. Reference to other sections
For personal protection see section 8.
7.1. Precautions for safe handling
Safe handling advice
Keep container tightly closed. Ensure there is good room ventilation.
Advice on protection against fire and explosion
Keep away from sources of ignition --- No smoking. Take precautionary measures against static discharges. In the event of fire, cool the endangered containers with water. When heated above the flash point and/or during spraying (atomizing), ignitible mixtures may form in air. Use only explosion-proof equipment. Vapours are heavier than air and may spread along floors.
7.2. Conditions for safe storage, including any incompatibilities
Requirements for storage areas and containers
Keep only in the original container at a temperature not exceeding 30 °C. Protect from the action of light. Fill the container by approximately 90 % only as oxygen (air) is required for stabilisation. With large storage containers make sure the oxygen (air) supply is sufficient to ensure stability. Can polymerize with intense heat release.
7.3. Specific end use(s)
Components or products of decomposition, with limit values related to the place of work which require monitoring
methyl methacrylate, cas no. 80-62-6
Indicative occupational exposure limit value (long-term) established by the EU:
2009/161/EC 2009: 50 ppm
Indicative occupational exposure limit value (short-term)
2009/161/EC (15 minutes) 2009: 100 ppm
A large number of EU member states have also established national occupational exposure limits for MMA. The majority has also adopted 50 ppm / 200-210 mg/m³ (A, B, D, EST, H, I, IRL, LT, P, S, SP, SK, SLO, UK), while a smaller number of EU member states have established lower (BG, CZ, DK, FIN, LV, NL, PL) or higher OELs for MMA (GR, F) (as of spring 2010)
For monitoring procedures refer to for instance "Empfohlene Analysenverfahren für Arbeitsplatzmessungen", Schriftenreihe der Bundesanstalt für
Arbeitsschutz and "NIOSH Manual of Analytical Methods", National Institute for Occupational Safety and Health
Critical component Routes of exposure Workers Industry/trade
methyl methacrylate Inhalation (Long-term) 208 mg/m³
methyl methacrylate dermal (Long-term) 13.7 mg/kg/d
methyl methacrylate Oral (Long-term) -
methyl methacrylate Inhalation (Short-term) 416 mg/m³
Critical component Routes of exposure value
methyl methacrylate water (Long-term) 0.94 mg/l
methyl methacrylate Soil (Long-term) -
methyl methacrylate Air (Long-term) -
Do not breathe vapours. Avoid contact with eyes and skin. Do not eat, drink or smoke during use.
Store work clothing separately. Take off all contaminated clothing immediately. Follow the usual good standards of occupational hygiene. Clean skin thoroughly
after work; apply skin cream.
Breathing apparatus in case of high concentrations, short term: filter appliance, filter A
butyl rubber gloves (0.3 mm), Break through time 60 min (EN 374)
In practice, due to variable exposure conditions, this information can only be an aid to orientation for the selection of a suitable chemical protection glove. In particular, this information does not substitute suitability tests by the end user.
nitrile rubber gloves (minimal thickness 0.11 mm)
Gloves should be replaced regularly, especially after extended contact with the product. For each work-place a suitable glove type has to be selected.
tightly fitting goggles
Skin and body protection
On handling of larger quantities: face mask, chemical-resistant boots and apron
see section 10.2.
10.2. Chemical stability
No decomposition if used as directed.
10.3. Possibility of hazardous reactions
Polymerization with heat evolution may occur in the presence of radical forming substances (e.g. peroxides), reducing substances, and/or heavy metal ions. The product is normally supplied in a stabilized form. If the permissible storage period and/or storage temperature is exceeded, the product may polymerize with heat evolution.
10.4. Conditions to avoid
Keep away from heat and sources of ignition.Protect from the action of light.The product is normally supplied in a stabilized form. If the permissible storage period and/or storage temperature is exceeded, the product may polymerize with heat evolution.
10.5. Incompatible materials
Free radical initiators. Reducing agents. Tertiary amines. Heavy metals. peroxides Oxidizing agents Mineral acids.
Waste is hazardous. It must be disposed of in accordance with the regulations after consultation of the competent local authorities and the disposal
company in a suitable and licensed facility.
Contaminated packaging should be emptied optimally and after appropriate professional cleansing may be taken for reuse. Packaging that cannot be cleaned should be disposed of professionally. Uncontaminated packaging may be taken for recycling.
Code of waste EWC 07 02 08
Waste from the manufacture, formulation, supply and use (MFSU) of plastics, synthetic rubber and man-made fibres - other still bottoms and reaction residues. Always check the given waste codes according to the actual conditions of manufacturing, formulation or use in your facilities.
