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
Flush eyes thoroughly with a large amount of water and consult 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., Skin Sensitisation
4.3. Indication of any immediate medical attention and special treatment needed
Treat symptomatically.

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
full 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. Do not breathe vapours or spray mist. Do not eat, drink or smoke when using this product. Wash hands thoroughly with soap and water after handling.
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.
7.2. Conditions for safe storage, including any incompatibilities
Requirements for storage areas and containers
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. Keep only in the original container at a temperature not exceeding 30 °C. 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
n-Butyl methacrylate, CAS no. 97-88-1
No Indicative Occupational exposure Limit Value (long-term) has been established by the EU. A number of national OELs have been established ranging from 5 ppm in Latvia, which kept the Russian value and 50 ppm in a number of countries (ET, LT, SV), which has been set by analogy to MMA. The Dutch OEL (also NO) of 10 ppm is based on MMA data and in particular on a study which has been recognized to be flawed in subsequent assessments by SCOEL and UK HSE.

8.1. Control parameters
see section 8.2.

8.2 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
Take off all contaminated clothing immediately. Store work clothing separately. 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 76 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
