Description of first aid measures
· General information:
Immediately remove any clothing soiled by the product.
Symptoms of poisoning may even occur after several hours; therefore medical observation for at least 48 hours after the accident.
Remove breathing equipment only after contaminated clothing have been completely removed.
Take note of the following instructions:
· After inhalation:
Supply fresh air or oxygen; call for doctor.
In case of unconsciousness place patient stably in the recovery position for transportation.
· After skin contact:
Immediately wash with water and soap and rinse thoroughly.
If skin irritation occurs, consult a doctor.
· After eye contact:
Rinse opened eye for several minutes under running water. Then consult a doctor.
· After swallowing: Do not induce vomiting; call for medical help immediately.
· Most important symptoms and effects, both acute and delayed: No further relevant information available.
· Indication of any immediate medical attention and special treatment needed: No further relevant information available.

Fire-fighting measures
· Extinguishing media
· Suitable extinguishing agents:
CO2, powder or water spray. Fight larger fires with water spray or alcohol resistant foam.
· For safety reasons unsuitable extinguishing agents: Water with full jet
· Special hazards arising from the substance or mixture
Can form explosive gas-air mixtures.
Carbon monoxide and carbon dioxide
· Advice for firefighters
· Protective equipment:
Mount respiratory protective device.
Wear personal protective equipment.
· Additional information
Cool endangered container(s) with water spray.
Heating of container(s) will cause pressure rise with risk of bursting and subsequent explosion (BLEVE).
Dispose of fire debris and contaminated fire fighting water in accordance with official regulations.

Nitrile rubber, NBR
Recommended thickness of the material: >= 0.7 mm
· Penetration time of glove material
