First-aid measures
4.1. Description of first aid measures
Remove contaminated clothing. First aid personnel should pay attention to their own safety.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention. If breathing difficulties develop, aid in breathing and seek immediate medical attention.
On skin contact:
Immediately wash thoroughly with plenty of water, apply sterile dressings, consult a skin specialist.
On contact with eyes:
In case of contact with the eyes, rinse immediately for at least 15 minutes with plenty of water. Immediate medical attention required.
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: Eye irritation, respiratory disorders, dazed state, nausea, skin irritation, headache, giddiness, sickness, Further symptoms are possible
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:
carbon dioxide, dry powder
Unsuitable extinguishing media for safety reasons:
water, chlorinated hydrocarbons, foam
5.2. Special hazards arising from the substance or mixture
At temperatures of > 50 °C can be emitted: Diborane(6), toxic gas
Reacts violently with water, liberating extremely flammable gases.
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. Contaminated extinguishing water must be disposed of in accordance with official regulations. Sealed containers should be protected against heat as this results in pressure build-up. 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
Reacts violently with water, liberating extremely flammable gases. Release of substance/product can cause fire or explosion.
6.1. Personal precautions, protective equipment and emergency procedures
Use personal protective clothing. Sources of ignition should be kept well clear.
6.2. Environmental precautions
Do not discharge into drains/surface waters/groundwater. Contain contaminated water/firefighting water.
6.3. Methods and material for containment and cleaning up
Pick up with suitable absorbent material. Place into suitable container for disposal. Correctly dispose of recovered product immediately.
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
Avoid contact with the skin, eyes and clothing. Avoid inhalation of dusts/mists/vapours. Keep container tightly sealed. Product should be worked up in closed equipment as far as possible. Handle under dry inert gas. Protect against moisture. Protect against heat. Protect from air. Ensure adequate ventilation.
Ensure thorough ventilation of stores and work areas. Handle in accordance with good industrial hygiene and safety practice. Remove contaminated clothing and protective equipment before entering eating areas. Hands and/or face should be washed before breaks and at the end of the shift. When using do not eat, drink or smoke.
Protection against fire and explosion:
Avoid all sources of ignition: heat, sparks, open flame. Take precautionary measures against static discharges. Use antistatic tools. Render equipment and apparatus inert (nitrogen, inert gases) and ground before putting into operation. Fire extinguishers should be kept handy. Sealed containers should be protected against heat as this results in pressure build-up. May form explosive peroxides.
7.2. Conditions for safe storage, including any incompatibilities
Segregate from oxidants. Segregate from acids and acid forming substances.
Further information on storage conditions: Keep container tightly closed in a cool, well-ventilated place. Keep under dry nitrogen. Protect against heat. Avoid all sources of ignition: heat, sparks, open flame.
Storage stability:
Store below 30°C (86°F) under temperature-controlled conditions.
To protect product purity, store below 5°C.
Improper storage may result in pressure build up in the drums.
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
8.2. Exposure controls
Personal protective equipment
Respiratory protection:
Respiratory protection in case of vapour/aerosol release. Combination filter for gases/vapours of organic, inorganic, acid inorganic and alkaline compounds (e.g. EN 14387 Type ABEK). Suitable respiratory protection for higher concentrations or long-term effect: Self-contained breathing apparatus.
Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials short-term contact and/or splashes (recommended: At least protective index 2, corresponding > 30 minutes of permeation time according to EN 374)
Polyethylene-Laminate (PE laminate) - ca. 0.1 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.
Manufacturer's directions for use should be observed because of great diversity of types.
Eye protection:
Tightly fitting safety goggles (cage goggles) (e.g. EN 166) and face shield.
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)., Protective clothing should be flame resistant.
General safety and hygiene measures
Avoid contact with the skin, eyes and clothing. Avoid inhalation of vapour. Handle in accordance with good industrial hygiene and safety practice. When using, do not eat, drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift. Gloves must be inspected regularly and prior to each use. Replace if necessary (e.g. pinhole leaks). Take off immediately all contaminated clothing. Wash contaminated clothing before reuse.
