Material Safety Data Sheet
4. First-aid measures
General advice:
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:
Remove the affected individual into fresh air and keep the person calm. Assist in
breathing if necessary.
Immediate medical attention required.
