First-aid measures

4.1. Description of first aid measures

General advice

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.

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, Skin Sensitisation, Causes skin and eye irritation.

4.3. Indication of any immediate medical attention and special treatment needed

Symptomatic treatment.

Fire-fighting measures

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.

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.

6.2. 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.

Handling and storage

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)

no

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)

Exposure controls

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

Protective measures

Do not breathe vapours. Avoid contact with eyes and skin. Do not eat, drink or smoke during use.

Hygiene measures

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.

Respiratory protection

Breathing apparatus in case of high concentrations, short term: filter appliance, filter A

Hand protection

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.

Splash protection
