Section 4. First Aid Measures
Eye ContactCheck 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 immediately.
Skin ContactIn 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 ContactWash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek
immediate medical attention.
InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical attention immediately.
Serious InhalationEvacuate 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.
IngestionDo NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to
an unconscious person. If large quantities of this material are swallowed, call a physician immediately.
Loosen tight clothing such as a collar, tie, belt or waistband.

Section 7. Handling and Storage
PrecautionsKeep container dry. Keep away from heat. Keep away from sources of ignition. Empty containers pose a
fire risk, evaporate the residue under a fume hood. Ground all equipment containing material. Do not
ingest. Do not breathe gas/fumes/ vapor/spray. Never add water to this product. 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.
StorageKeep container tightly closed. Keep container in a cool, well-ventilated area.

Section 8. Exposure Controls/Personal Protection
Engineering ControlsProvide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors
below their respective threshold limit value. Ensure that eyewash stations and safety showers are proximal
to the work-station location.
Personal ProtectionFace shield. Full suit. Vapor respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves. Boots. Respiratory protection is not necessary for normal handling. Good room ventilation or use
of local exhaust (fume hood) is sufficient. Use a vapor respirator under conditions where exposure to the
substance is apparent (e.g. generation of high concentrations of mist or vapor, inadequate ventilation,
development of respiratory tract irritation), and engineering controls are not feasible. Be sure to use an
approved/certified respirator or equivalent.
Personal Protection in Case of Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self contained breathing apparatus should
a Large Spillbe used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a
specialist BEFORE handling this product.
