First-aid measures

Description of first aid measures
General advice
Remove soiled, soaked 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.On contact with water, diluted acid is

Move subject to fresh air and keep him calm. Contact a doctor immediately.

Skin contact
See a physician. Wash off immediately with soap and water.

Eye contact
Keeping the eyelids apart, immediately flush eye with water for at least 15 minutes.
Protect uninjured eye. See a physician. Call ambulance (cue: caustic burn of the

Do not induce vomiting. Contact a doctor immediately.

Most important symptoms and effects, both acute and delayed
Skin irritation, Causes eye irritation., nausea

Indication of any immediate medical attention and special treatment needed

Fire-fighting measures

Extinguishing media
Suitable extinguishing media
water spray, foam, dry chemical, carbon dioxide

Extinguishing media which must not be used for safety reasons
full water jet

Special hazards arising from the substance or mixture
Closed container may rupture if strongly heated.

Advice for firefighters
Wear self-contained breathing apparatus.
Closed container may rupture if strongly heated.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Take care for adequate ventilation. Use personal protective clothing. Keep away sources of ignition. Use breathing
apparatus if exposed to vapours/dust/mist/aerosol.

Environmental precautions
Prevent product from getting into drains/surface water/groundwater.

Methods and material for containment and cleaning up
Larger quantities:
Take up mechanically (by pumping). 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

Handling and storage

Precautions for safe handling
Safe handling advice Keep container tightly closed. Ensure the area is well ventilated.

Advice on protection against fire and explosion
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.

Conditions for safe storage, including any incompatibilities
Requirements for storage areas and containers
Protect from 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. Keep only in the original container at a
temperature not exceeding 30 °C. Can polymerize with intense heat release.

Advice on common storage
Do not store together with alkalies.

Exposure controls / personal protection

Components or products of decomposition according to point 10, with limit values related to the place of work
which require monitoring
methacrylic acid 79-41-4
WEL (long-term) 2009 72 mg/m3 20 ppm
WEL (short-term) 2009 143 mg/m3 40 ppm

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 inhale vapours. Absolutely avoid contact with the eyes and/or skin. Safety
shower and eye wash fountain should be available.

Hygiene measures
Store work clothing separately. Remove soiled or soaked 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,
combination filter ABEK

Hand protection
butyl rubber gloves (0.3 mm), Break through time approx. 480 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.

General information
Gloves should be replaced regularly, especially after extended contact with the
product. For each work-place a suitable glove type has to be selected.

Eye protection
tightly fitting goggles

Skin and body protection
On handling of larger quantities: face mask, chemical-resistant boots and apron

Stability and reactivity

Reactivity and Chemical Stability
No decomposition when used as directed.

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.
Reactions with alkalis.

Conditions to avoid
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.

Incompatible materials
Reducing agents.
Tertiary amines.
Heavy metals.
Free radical initiators.
Mineral acids.
Reactions with strong oxidizing agents.

Hazardous decomposition products
None when used as directed.

Disposal considerations

Waste treatment 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.

Uncleaned packaging
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

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.
