Guidance on Safe Use
Administrative data
First-aid measures
General advice :
Take affected persons out of danger area and lay down.
Immediately remove any clothing soiled by the product.
In case of irregular breathing or respiratory arrest provide artificial respiration.
Inhalation :
Supply fresh air and to be sure call for a doctor.
In case of unconsciousness place patient stably in side position for transportation.
Skin contact :
Immediately rinse with water.
If skin irritation continues, consult a doctor.
Eye contact :
IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to
do. Continue rinsing.
Seek medical treatment.
Ingestion :
Rinse out mouth and then drink plenty of water.
Do NOT induce vomiting.
Call for a doctor immediately.
May cause respiratory irritation. If inhalation occurs, signs and symptoms may include sore throat, headache, nausea, coughing, choking, wheezing, difficulty in breathing, chest congestion, shortness of breath and may cause transient central nervous system (CNS) depression.
Fire-fighting measures
Suitable extinguishing media :
CO2, powder or water spray. Fight larger fires with water spray or alcohol resistant foam.
Use fire extinguishing methods suitable to surrounding conditions.
Unsuitable Extinguishing Media :
Do NOT use water jet.
Simultaneous use of foam and water on the same surface is to be avoided as water destroys the foam.
Combustion Products :
Carbon monoxide, carbon dioxide and unburned hydrocarbons (smoke).
Specific hazards during fire fighting :
Vapour is denser than air – flashback may be possible over considerable distances.
Containers may explode under fire conditions - use water spray to cool unopened containers.
Do not allow run-off from fire fighting to enter drains or water courses – may cause explosion hazard in drains and may reignite on surface water.
Further information :
Special protective equipment for fire-fighters :
Wear an approved positive pressure self-contained breathing apparatus in addition to standard fire fighting gear.
Accidental release measures
Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area).
Personal precautions :
Wear personal protective equipment.
Avoid breathing vapours or mist.
Ensure adequate ventilation and absence of sources of ignition.
Beware of accumulation of vapours in low areas or contained areas, where explosive concentrations may occur.
Environmental precautions :
Do not allow product to reach sewage system or any water course.
Land spillage :
Prevent further leakage or spillage if safe to do so.
Prevent spillage from entering drains, sewer, basement or confined areas.
Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust).
Dispose of the material collected according to regulations.
Water spillage :
Prevent further leakage or spillage if safe to do so.
If the spillage contaminates rivers, lakes or drains inform respective authorities.
Water spillage:
If the Flash Point exceeds the Ambient Temperature by 10 deg C or more, use containment booms and remove from the surface by skimming or with suitable absorbents when conditions permit. If the Flash Point does not exceed the Ambient Air Temperature by at least 10 deg C, use booms as a barrier to protect shorelines and allow material to evaporate. Seek the advice of a specialist before using dispersants.
Handling and storage
- Precautions for safe handling:
Ensure good ventilation/exhaustion at the workplace.
Prevent formation of aerosols
- Information about fire and explosion protection:
Keep ignition sources away - Do not smoke.
Protect from heat.
- Conditions for safe storage, including any incompatibilities:
Store only in the original receptacle.
Vapour space above stored liquid may be flammable/explosive unless blanketed with inert gas.
Store away from oxidising agents.
Keep container tightly sealed.
Store in cool, dry conditions in well sealed receptacles.
Protect from heat and direct sunlight.

Exposure controls / personal protection
1. General protective and hygienic measures
Do not eat, drink, smoke or sniff while working.
Keep away from foodstuffs, beverages and feed.
Immediately remove all soiled and contaminated clothing.
Store protective clothing separately.
Avoid contact with the eyes and skin.
The usual precautionary measures are to be adhered to when handling chemicals.
2. Hand protection
Protective gloves
Only use chemical-protective gloves with CE-labelling of category III.
The glove material has to be impermeable and resistant to the product/ the substance/ the preparation.
Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation.
3. Body protection
Protective work clothing
4. Eye protection
Tightly sealed goggles
5. Respiratory protection
In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure
use self-contained respiratory protective device.
Stability and reactivity
