First-aid measures
Description of first aid measures
Immediately remove contaminated clothing. If the patient is likely to become unconscious, place and
transport in stable sideways position (recovery position).
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:
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.
Most important symptoms and effects, both acute and delayed
Toxic if swallowed.
Very toxic by inhalation and in contact with skin.
Limited evidence of a carcinogenic effect.
Also harmful: danger of serious damage to health by prolonged exposure if swallowed.
May cause harm to the unborn child.
Hazards: No hazard is expected under intended use and appropriate handling.
Indication of any immediate medical attention and special treatment needed
Treatment: Treat according to symptoms (decontamination, vital functions), for formation of
methaemoglobin administer dimethylaminophenol followed by sodium thiosulphate. Artificial
respiration with oxygen.
Fire-fighting measures
Extinguishing media
Suitable extinguishing media:
water spray, carbon dioxide, dry powder, foam
Special hazards arising from the substance or mixture
hydrogencyanide...%; hydrocyanic acid...%
Vapors and/or decomposition products are irritant and/or toxic.
Advice for fire-fighters
Special protective equipment:
Wear self-contained breathing apparatus and chemical-protective clothing.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: wear a tightly closed chemical protection suit and a self-contained breathing
apparatus.
Environmental precautions
Do not empty into drains. Contain contaminated water/firefighting water.
Methods and material for containment and cleaning up
For large amounts: Pick up with suitable absorbent material (e.g. sand, sawdust, general-purpose
binder, kieselguhr). Pack in tightly closed containers for disposal.
Ensure adequate ventilation.
Handling and storage
Precautions for safe handling
Processing machines must be fitted with local exhaust ventilation. Wear suitable protective clothing
and gloves. Avoid aerosol formation. Use only in enclosed systems.
Conditions for safe storage, including any incompatibilities
Unsuitable materials for containers: aluminum
Further information on storage conditions: Avoid all sources of ignition: heat, sparks, open flame.
Keep container tightly closed and dry; store in a cool place.
Specific end use(s)
For the relevant identified use(s) the advice mentioned in this section is to be observed.

8.2. Exposure controls
Personal protective equipment
Respiratory protection:
Respiratory protection in case of vapour/aerosol release. Self-contained breathing apparatus.
Suitable respiratory protection for lower concentrations or short-term effect: Full face mask with
combination filter type A - P2 (EN 136, 14387, 143)
Hand protection:
Suitable materials also with prolonged, direct contact (Recommended: Protective index 6,
corresponding > 480 minutes of permeation time according to EN 374):
fluoroelastomer (FKM) - 0.7 mm coating thickness
chloroprene rubber (CR) - 0.5 mm coating thickness
butyl rubber (butyl) - 0.7 mm coating thickness
polyvinylchloride (PVC) - 0.7 mm coating thickness
Suitable materials short-term contact and/or splashes (recommended: At least protective index 2,
corresponding > 30 minutes of permeation time according to EN 374)
natural rubber/natural latex (NR) - 0.5 mm coating thickness
nitrile rubber (NBR) - 0.4 mm coating thickness
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:
full protection suit with breathing-air supply (f.e. according to EN 943)
General safety and hygiene measures
Avoid contact with the skin, eyes and clothing. Do not breathe vapour/spray. Wearing of closed work
clothing is recommended.
Handle in accordance with good industrial hygiene and safety practice
