Guidance on Safe Use
Administrative data
First-aid measures
Description of first aid measures
If inhaled:
Fresh air. Assist breathing with a ventilator bag or ventilator.
On skin contact:
Wash off thoroughly with ample water. Remove contaminated clothing.
On contact with eyes:
Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open,
consult an eye specialist.
On ingestion:
Rinse mouth immediately and then drink plenty of water, seek medical attention. Do not induce
vomiting due to aspiration hazard.
Most important symptoms and effects, both acute and delayed
Indication of any immediate medical attention and special treatment needed
Treatment: Stomach wash.
Fire-fighting measures
Extinguishing media
Suitable extinguishing media:
water spray, dry powder, foam
Special hazards arising from the substance or mixture
Vapours may form explosive mixture with air.
Advice for fire-fighters
Special protective equipment:
Wear self-contained breathing apparatus and chemical-protective clothing.
Further information:
Accidental release measures
May form explosive peroxides.
Personal precautions, protective equipment and emergency procedures
Do not breathe vapour/spray. Avoid contact with the skin, eyes and clothing. Ensure adequate
ventilation.
Environmental precautions
Do not empty into drains.
Methods and material for containment and cleaning up
For small amounts: Pick up with suitable absorbent material. Dispose of absorbed material in
accordance with regulations.
Reference to other sections
Information regarding exposure controls/personal protection and disposal considerations can be found
in section 8 and 13.
Handling and storage
Precautions for safe handling
Work only in fume cupboards. Avoid aerosol formation.
Protection against fire and explosion:
Keep away from sources of ignition - No smoking. Take precautionary measures against static
discharges. The product is combustible. Vapours are heavier than air.
Conditions for safe storage, including any incompatibilities
Suitable materials for containers: glass, steel
Further information on storage conditions: Keep container tightly closed and in a well-ventilated place.
Avoid all sources of ignition: heat, sparks, open flame.
Protect from temperatures below: 5 °C
Protect from temperatures above: 30 °C

Exposure controls / personal protection
Control parameters
Components with workplace control parameters
Observe the appropriate BAT value (Germany). The values and other data of TRGS 900 (Germany)
must be observed.
78-93-3: Methylethylketone
Exposure controls
Personal protective equipment
Respiratory protection:
Respiratory protection in case of vapour/aerosol release. Gas filter for gases/vapours of organic
compounds (boiling point >65 °C, e. g. EN 14387 Type A)
Hand protection:
Suitable materials short-term contact and/or splashes (recommended: At least protective index 2,
corresponding > 30 minutes of permeation time according to EN 374)
butyl rubber (butyl) - 0.7 mm coating thickness
Manufacturer's directions for use should be observed because of great diversity of types.
Supplementary note: The specifications are based on tests, literature data and information of glove
manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g.
temperature) it must be considered, that the practical usage of a chemical-protective glove in practice
may be much shorter than the permeation time determined through testing.Eye protection:
Tightly fitting safety goggles (splash goggles) (e.g. EN 166)
Body protection:
Body protection must be chosen based on level of activity and exposure.
General safety and hygiene measures
Do not inhale gases/vapours/aerosols. Take off immediately all contaminated clothing. Hands and/or
face should be washed before breaks and at the end of the shift. Preventive skin protection necessary
Stability and reactivity
Vapours may form explosive mixture with air.
Chemical stability
Possibility of hazardous reactions
Possibility of peroxide formation.
Conditions to avoid
Avoid extreme heat.
Incompatible materials
Substances to avoid:
chromium trioxide, oxidizing agents
Hazardous decomposition products
Disposal considerations
Waste treatment methods
Dispose of in accordance with local authority regulations.
Contaminated packaging:
Uncleaned empties should be disposed of in the same manner as the contents.
