Administrative data
First-aid measures
EYE CONTACT. Bathe the eye with running water for at least 15 minutes, including beneath upper and lower eyelids. Consult a doctor or transfer to a medical centre immediately.
SKIN CONTACT. Remove all contaminated clothes and footwear immediately unless stuck to skin. Drench the affected skin with running water for 10 minutes or longer if substance is still on skin. Consult a doctor if there are burns or symptoms of poisoning.
INHALATION. Remove casualty from exposure ensuring one's own safety whilst doing so. If conscious, ensure the casualty sits or lies down. If unconscious, check for breathing and apply artificial respiration if necessary. Consult a doctor.
INGESTION. Wash out mouth with water. Do not induce vomiting. If conscious, give half a litre of water to drink immediately. If unconscious, check for breathing and apply artificial respiration if necessary. If unconscious and breathing is OK, place in the recovery position. Transfer to hospital as soon as possible.
Fire-fighting measures
EXTINGUISHING MEDIA. Suitable extinguishing media for the surrounding fire should be used. Water. Water spray. Carbon dioxide. Alcohol or polymer foam.
EXPOSURE HAZARDS Corrosive to eyes. In combustion emits toxic fumes of carbon dioxide / carbon monoxide and organics.
ADVICE FOR FIRE-FIGHTERS. Wear self-contained breathing apparatus. Wear protective clothing to prevent contact with skin and eyes.
Accidental release measures
PERSONAL PRECAUTIONS.: Evacuate the area immediately. If outside do not approach from downwind. Avoid generating dusts. Mark out the contaminated area with signs andprevent access to unauthorised personnel. Do not attempt to take action without suitable protective clothing.
ENVIRONMENTAL PRECAUTIONS. : Contain the spillage as far as possible. .Do not discharge into drains or rivers.
CLEAN-UP PROCEDURES. Clean-up should be dealt with only by qualified personnel familiar with the specific substance. Transfer to a closable, labelled salvage container for disposal by an appropriate method.
Handling and storage
HANDLING REQUIREMENTS. : Avoid direct contact with the substance. Ensure there is sufficient ventilation of the area. Do not handle in a confined space. Avoid the formation or spread of dust in the air.
STORAGE CONDITIONS. Store in cool, well ventilated area. Keep container tightly closed.
