First-aid measures

Eye contact
Immediately flush eyes with plenty of water, occasionally lifting the upper and lower
eyelids. Check for and remove any contact lenses. Continue to rinse for at least 10
minutes. Get medical attention.

Inhalation
Remove victim to fresh air and keep at rest in a position comfortable for breathing. If
it is suspected that fumes are still present, the rescuer should wear an appropriate
mask or self-contained breathing apparatus. If not breathing, if breathing is irregular
or if respiratory arrest occurs, provide artificial respiration or oxygen by trained
personnel. It may be dangerous to the person providing aid to give mouth-to-mouth
resuscitation. Get medical attention. If necessary, call a poison center or physician.
If unconscious, place in recovery position and get medical attention immediately.
Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.

Skin contact
Flush contaminated skin with plenty of water. Remove contaminated clothing and
shoes. Get medical attention if symptoms occur. Wash clothing before reuse. Clean
shoes thoroughly before reuse.

Ingestion
Wash out mouth with water. Remove dentures if any. Remove victim to fresh air and
keep at rest in a position comfortable for breathing. If material has been swallowed
and the exposed person is conscious, give small quantities of water to drink. Stop if
the exposed person feels sick as vomiting may be dangerous. Do not induce vomiting
unless directed to do so by medical personnel. If vomiting occurs, the head should be
kept low so that vomit does not enter the lungs. Get medical attention if adverse
health effects persist or are severe. Never give anything by mouth to an unconscious
person. If unconscious, place in recovery position and get medical attention
immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt
or waistband.

Protection of first-aiders
No action shall be taken involving any personal risk or without suitable training. If it is
suspected that fumes are still present, the rescuer should wear an appropriate mask
or self-contained breathing apparatus. It may be dangerous to the person providing
aid to give mouth-to-mouth resuscitation.



Fire-fighting measures

Extinguishing media

Suitable extinguishing media
Use dry chemical, CO2, water spray (fog) or foam.

Unsuitable extinguishing media
Do not use water jet.

Special hazards arising from the substance or mixture

Hazards from the substance or mixture
Highly flammable liquid and vapor. In a fire or if heated, a pressure increase will
occur and the container may burst, with the risk of a subsequent explosion. The
vapour/gas is heavier than air and will spread along the ground. Vapours may
accumulate in low or confined areas or travel a considerable distance to a source of
ignition and flash back. Runoff to sewer may create fire or explosion hazard. May
form explosive peroxides.

Hazardous combustion products
Decomposition products may include the following materials:
carbon dioxide
carbon monoxide

Advice for firefighters

Special precautions for firefighters
Promptly isolate the scene by removing all persons from the vicinity of the incident if
there is a fire. No action shall be taken involving any personal risk or without suitable
training. Move containers from fire area if this can be done without risk. Use water
spray to keep fire-exposed containers cool.

Special protective equipment for fire-fighters
Fire-fighters should wear appropriate protective equipment and self-contained
breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.
Clothing for fire-fighters (including helmets, protective boots and gloves) conforming
to European standard EN 469 will provide a basic level of protection for chemical
incidents.


Accidental release measures

Personal precautions, protective equipment and emergency procedures

For non-emergency personnel
No action shall be taken involving any personal risk or without suitable training.
Evacuate surrounding areas. Keep unnecessary and unprotected personnel from
entering. Do not touch or walk through spilt material. Shut off all ignition sources. No
flares, smoking or flames in hazard area. Avoid breathing vapour or mist. Provide
adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Put
on appropriate personal protective equipment.

For emergency responders
If specialised clothing is required to deal with the spillage, take note of any information
in Section 8 on suitable and unsuitable materials. See also the information in "For
non-emergency personnel".

Environmental precautions
Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains
and sewers. Inform the relevant authorities if the product has caused environmental
pollution (sewers, waterways, soil or air).

Methods and materials for containment and cleaning up

Small spill
Stop leak if without risk. Move containers from spill area. Dilute with water and mop
up if water-soluble. Alternatively, or if water-insoluble, absorb with an inert dry
material and place in an appropriate waste disposal container. Use spark-proof tools
and explosion-proof equipment. Dispose of via a licensed waste disposal contractor.

Large spill
Stop leak if without risk. Move containers from spill area. Approach the release from
upwind. Prevent entry into sewers, water courses, basements or confined areas.
Wash spillages into an effluent treatment plant or proceed as follows. Contain and
collect spillage with non-combustible, absorbent material e.g. sand, earth, vermiculite
or diatomaceous earth and place in container for disposal according to local
regulations (see section 13). Use spark-proof tools and explosion-proof equipment.
Dispose of via a licensed waste disposal contractor. Contaminated absorbent
material may pose the same hazard as the spilt product. Note: see section 1 for
emergency contact information and section 13 for waste disposal.


Handling and storage

Precautions for safe handling

Protective measures
Put on appropriate personal protective equipment (see Section 8). Do not ingest.
Avoid contact with eyes, skin and clothing. Avoid breathing vapour or mist. Use only
with adequate ventilation. Wear appropriate respirator when ventilation is inadequate
Do not enter storage areas and confined spaces unless adequately ventilated. Keep
in the original container or an approved alternative made from a compatible material,
kept tightly closed when not in use. Store and use away from heat, sparks, open
flame or any other ignition source. Use explosion-proof electrical (ventilating, lighting
and material handling) equipment. Use only non-sparking tools. Take precautionary
measures against electrostatic discharges. Empty containers retain product residue
and can be hazardous. Do not reuse container.

Advice on general occupational hygiene
Eating, drinking and smoking should be prohibited in areas where this material is
handled, stored and processed. Workers should wash hands and face before eating,
drinking and smoking. Remove contaminated clothing and protective equipment
before entering eating areas. See also Section 8 for additional information on hygiene
measures.

Conditions for safe storage, including any incompatibilities
Store in accordance with local regulations. Store in a segregated and approved area.
Store in original container protected from direct sunlight in a dry, cool and wellventilated
area, away from incompatible materials (see section 10) and food and
drink. Store locked up. Eliminate all ignition sources. Separate from oxidizing
materials. Keep container tightly closed and sealed until ready for use. Containers
that have been opened must be carefully resealed and kept upright to prevent
leakage. Do not store in unlabelled containers. Use appropriate containment to
avoid environmental contamination.
