Section 4: First Aid Measures
Eye Contact:
Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at
least 15 minutes. Cold water may be used. Get medical attention.
Skin Contact:
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated
clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash clothing before
reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate
medical attention.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get
medical attention immediately.
Serious Inhalation:
Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
resuscitation. WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth resuscitation
when the inhaled material is toxic, infectious or corrosive. Seek immediate medical attention.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical
attention immediately.

Precautions:
Keep locked up.. Keep away from heat. Keep away from sources of ignition. Ground all equipment containing
material. Do not ingest. Do not breathe dust. Take precautionary measures against electrostatic discharges.
Wear suitable protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment. If
ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes.
Keep away from incompatibles such as oxidizing agents, reducing agents, combustible materials, alkalis,
moisture.
Storage:
Keep container in a cool, well-ventilated area. Keep container tightly closed and sealed until ready for use. Avoid
all possible sources of ignition (spark or flame). Do not store above 23°C (73.4°F).
Section 8: Exposure Controls/Personal Protection
Engineering Controls:
Use explosion-proof electrical (ventilating, lighting and material handling) equipment. Use process enclosures,
local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure
limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants
below the exposure limit.
