Isobutyraldehyde

Guidance on Safe Use

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. First aid
personnel should pay attention to their own safety.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention.
On skin contact:
Wash thoroughly with soap and water.
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 and then drink plenty of water.
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.
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

Extinguishing media
Suitable extinguishing media:
alcohol-resistant foam, carbon dioxide, dry powder
Unsuitable extinguishing media for safety reasons:
water spray
Additional information:
Water jet can rapidly spread fire.
Special hazards arising from the substance or mixture
Vapours may form explosive mixture with air. Cool endangered containers with water-spray. Risk of
bursting. Burning produces harmful and toxic fumes.
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. Vapours are heavier than air and may accumulate in low areas and travel a considerable
distance up to the source of ignition.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Avoid contact with the skin, eyes and clothing. Avoid all sources of ignition: heat, sparks, open flame.
Keep people away and stay on the upwind side. Breathing protection required.
Environmental precautions
Do not discharge into drains/surface waters/groundwater. Do not discharge into the subsoil/soil.
Methods and material for containment and cleaning up
For small amounts: Rinse away with water. Subject contaminated water to waste water treatment.
For large amounts: Pump off product.
For residues: Pick up with inert absorbent material (e.g. sand, earth etc.). Do not use saw-dust or
other combustible substances as an absorbant during cleanup. Dispose of absorbed material in
accordance with regulations.

Handling and storage

Precautions for safe handling
Avoid contact with the skin, eyes and clothing. 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.
Conditions for safe storage, including any incompatibilities
Further information on storage conditions: Keep container tightly closed in a cool, well-ventilated
place. Avoid all sources of ignition: heat, sparks, open flame.

Exposure controls / personal protection

Personal protective equipment Respiratory protection: Wear respiratory protection if ventilation is inadequate. Gas filter for gases/vapours of organic compounds (boiling point <65 °C, f.e. EN 14387 Type AX) 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) Body protection: Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of dust). General safety and hygiene measures Avoid inhalation of vapour. Handle in accordance with good industrial hygiene and safety practice. Wearing of closed work clothing is required additionally to the stated personal protection equipment.
