Guidance on Safe Use

First-aid measures

General:       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.

4.1 Description of first aid measures

Inhalation:       Move subject to fresh air and keep him calm. See a physician.

Skin Contact:       Wash off immediately with soap and water. If skin irritation occurs consult a physician.

Eye contact:       Keeping the eyelids apart flush thoroughly with water immediately. If irritation persists, contact a physician.

Ingestion:       Do not induce vomiting. Call a physician immediately.

4.2 Most important symptoms and effects, both acute and delayed:       Headache. confusion Causes skin and eye irritation. Sensitization

4.3 Indication of any immediate medical attention and special treatment needed

Hazards:       May cause sensitization by skin contact.

Treatment:       Treat symptomatically.

Fire-fighting measures

General Fire Hazards:       Standard procedure for chemical fires. Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. Vapours are heavier than air and can form an explosive mixture with air. Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations. Prevent fire extinguishing water from contaminating surface water or the ground water system.Retention of fire-extinguishing water in Germany: see FireExtinguishing Water Retention Directive "LoeRueRL":

5.1 Extinguishing media

Suitable extinguishing media:       Extinguish with foam, carbon dioxide or dry powder.

Unsuitable extinguishing media:       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

Special fire fighting procedures:       Keep away from sources of ignition - No smoking. Take action to prevent 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.

Special protective equipment for fire-fighters:       Wear self-contained breathing apparatus.

Accidental release measures

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.

      

6.1.1 For non-emergency personnel:       Evacuate area and do not approach spilled product. ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). For personal protection see section 8.

      

6.1.2 For emergency responders:       No data available.

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. For disposal considerations see section 13.

Handling and storage

7.1 Precautions for safe handling:       Keep container tightly closed. Ensure there is good room ventilation. Do not breathe vapors. Avoid contact with skin and eyes. Do not eat, drink or smoke during use. Keep away from sources of ignition - No smoking. Take action to prevent 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:       Keep only in the original container at a temperature not exceeding 30 °C. 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. Protect from the action of light.

Storage Class:       3: Flammable Liquids

7.3 Specific end use(s):       We are unaware of any specific end uses which go beyond the data reported in Section 1.

Exposure controls / personal protection

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)

Disposal considerations

13.1 Waste treatment methods

General information:       Dispose of waste and residues in accordance with local authority requirements.

Disposal methods:       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. Strictly controlled conditions during disposal or treatment to air, wastewater and waste. Do not add wastewater to a biological wastewater treatment plant Bring wastewater containing AOX for professional disposal. The waste key number must be determined as per the European Waste Types List (decision on EU Waste Types List 2000/532/EC) in cooperation with the disposal firm / producing firm / official authority.

Contaminated Packaging:       Contaminated packaging should ideally be emptied; it can then be recycled after having been decontaminated. Packaging that cannot be cleaned should be disposed of professionally. Uncontaminated packaging may be taken for recycling.
