First-aid measures
4.1. Description of first aid measures
Immediately remove contaminated clothing. If danger of loss of consciousness, place patient in recovery position and transport accordingly. Apply artificial respiration if necessary.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention.
On skin contact:
Immediately wash thoroughly with soap and water, seek medical attention.
On contact with eyes:
Wash affected eyes for at least 15 minutes under running water with eyelids held open. If irritation develops, seek medical attention.
On ingestion:
Rinse mouth immediately and then drink plenty of water, seek medical attention.
4.2. Most important symptoms and effects, both acute and delayed
Symptoms: The most important known symptoms and effects are described in the labelling (see section 2) and/or in section 11.
4.3. Indication of any immediate medical attention and special treatment needed
Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote.
Fire-fighting measures
5.1. Extinguishing media
Suitable extinguishing media:
water spray, carbon dioxide, dry powder, foam
5.2. Special hazards arising from the substance or mixture
nitrogen oxides, carbon oxides
The substances/groups of substances mentioned can be released in case of fire. Under certain conditions in case of fire other hazardous combustion products may be generated.
5.3. Advice for fire-fighters
Special protective equipment:
Wear self-contained breathing apparatus and chemical-protective clothing.
Further information:
Collect contaminated extinguishing water separately, do not allow to reach sewage or effluent systems.
Accidental release measures
6.1. Personal precautions, protective equipment and emergency procedures
Avoid inhalation. Avoid contact with the skin, eyes and clothing.
6.2. Environmental precautions
Do not empty into drains.
6.3. Methods and material for containment and cleaning up
For large amounts: Pump off product.
For residues: Pick up with suitable absorbent material (e.g. sand, sawdust, general-purpose binder, kieselguhr). Dispose of absorbed material in accordance with regulations.
6.4. Reference to other sections
Information regarding exposure controls/personal protection and disposal considerations can be found in section 8 and 13.
Handling and storage
7.1. Precautions for safe handling
Ensure thorough ventilation of stores and work areas.
Protection against fire and explosion:
Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should be kept handy.
7.2. Conditions for safe storage, including any incompatibilities
Further information on storage conditions: Keep under inert gas. Keep container tightly closed.
7.3. Specific end use(s)
For the relevant identified use(s) listed in Section 1 the advice mentioned in this section 7 is to be observed.

Exposure controls / personal protection
8.1. Control parameters
Components with occupational exposure limits
123-72-8: butyraldehyde
645-62-5: 2-Ethylhex-2-enal
PNEC
freshwater: 0.0147 mg/l
marine water: 0.00147 mg/l
intermittent release: 0.147 mg/l
STP: 20.97 mg/l
sediment (freshwater): 0.075 mg/kg
sediment (marine water): 0.0075 mg/kg
soil: 0.0179 mg/kg
oral (secondary poisoning):
No PNEC value available.
8.2. Exposure controls
Personal protective equipment
Respiratory protection:
Wear respiratory protection if ventilation is inadequate.
Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials also with prolonged, direct contact (Recommended: Protective index 6, corresponding > 480 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:
Safety glasses with side-shields (frame goggles) (e.g. EN 166)
General safety and hygiene measures
Avoid contact with the skin, eyes and clothing. Do not breathe vapour/spray. Wearing of closed work clothing is required additionally to the stated personal protection equipment. Handle in accordance with good industrial hygiene and safety practice.
Stability and reactivity
10.1. Reactivity
Corrosion to metals:
No data available.
10.2. Chemical stability
The product is stable under inert gas.
10.3. Possibility of hazardous reactions
When finely distributed, self-ignition is possible.
10.4. Conditions to avoid
Avoid humidity. Avoid all sources of ignition: heat, sparks, open flame.
10.5. Incompatible materials
Substances to avoid:
No data available.
10.6. Hazardous decomposition products
No data available.
Disposal considerations
13.1. Waste treatment methods
Incinerate in suitable incineration plant, observing local authority regulations.
Contaminated packaging:
Contaminated packaging should be emptied as far as possible; then it can be passed on for recycling after being thoroughly cleaned.
