4. FIRST AID MEASURES

General Information : Take appropriate steps to avoid fire, explosion and inhalation hazards.

DO NOT DELAY.

Eye Contact : Immediately flush eyes with large amounts of water for at least 15 minutes while holding eyelids open. Transport to the nearest medical facility for additional treatment.

Inhalation : Remove to fresh air. Do not attempt to rescue the victim unless proper respiratory protection is worn. If the victim has difficulty breathing or tightness of the chest, is dizzy, vomiting, or unresponsive, give 100% oxygen with rescue breathing or CPR as required and transport to the nearest medical facility.

Skin Contact : DO NOT DELAY. Remove contaminated clothing. Immediately flush skin with large amounts of water for at least 15 minutes, and follow by washing with soap and water if available. If redness, swelling, pain and/or blisters occur, transport to the nearest medical facility for additional treatment.

Ingestion : If swallowed, do not induce vomiting: transport to nearest medical facility for additional treatment. If vomiting occurs spontaneously, keep head below hips to prevent aspiration. If any of the following delayed signs and symptoms appear within the next 6 hours, transport to the nearest medical facility: fever greater than 101° F 38.3° C), shortness of breath, chest congestion or continued coughing or wheezing. If vomiting occurs spontaneously, keep head below hips to prevent aspiration. Give nothing by mouth.

Notes to physician

Most important : Breathing of high vapour concentrations may cause central nervous system

symptoms and effects, (CNS) depression resulting in dizziness, light-headedness, headache

both acute and delayed nausea and loss of coordination. Continued inhalation may result in unconsciousness and death. Eye irritation signs and symptoms may include a burning sensation, redness, swelling, and/or blurred vision. Respiratory irritation signs and symptoms may include a temporary burning sensation of the nose and throat, coughing, and/or difficulty breathing. Skin irritation signs and symptoms may include a burning sensation, redness, swelling, and/or blisters. Auditory system effects may include temporary hearing loss and/or ringing in the ears. Visual system disturbances may be evidenced by decreases in the ability to discriminate between colours.

Immediate medical : Potential for chemical pneumonitis. Call a doctor or poison control center for

attention, special guidance.

5. FIRE FIGHTING MEASURES

Clear fire area of all non-emergency personnel.

Specific Hazards : Liquids and the vapors are flammable. Vapor forms an explosive mixture with air. The vapor is heavier than air, spreads along the ground and distant ignition is possible. Hazardous combustion products may include: Carbon monoxide, formaldehyde.

Suitable Extinguishing Media : Foam. Dry chemical powder, carbon dioxide, sand or earth may be used for small fires only.

Unsuitable Extinguishing Media : Do not use water in a jet.

Protective Equipment for Firefighters : Proper protective equipment including breathing apparatus must be worn when approaching a fire in a confined space. Wear full protective clothing and self-contained breathing apparatus.

Other Advice : All storage areas should be provided with adequate fire fighting facilities. Evacuate the area of all non-essential personnel. Keep adjacent containers cool by spraying with water.

6. ACCIDENTAL RELEASE MEASURES

Personal Precautions, Protective Equipment and Emergency Procedures : Avoid inhaling vapour and/or mists. Avoid contact with the skin. Isolate hazard area and deny entry to unnecessary or unprotected personnel. Extinguish any naked flames. Do not smoke. Remove ignition sources. Avoid sparks. Avoid contact with spilled or released material. Immediately remove all contaminated clothing.

Environmental Precaution : Remove all possible sources of ignition in the surrounding area. Use appropriate containment to avoid environmental contamination. Prevent from spreading or entering drains, ditches or rivers by using sand, earth, or other appropriate barriers. Attempt to disperse the vapour or to direct its flow to a safe location for example by using fog sprays. Take precautionary measures against static discharge. Ensure electrical continuity by bonding and grounding (earthing) all equipment. Use appropriate containment to avoid environmental contamination. Ventilate contaminated area thoroughly.

Methods and Material for Containment andCleaning Up : Soak up residue with an absorbent such as clay, sand or other suitable material and dispose off properly. Shovel into a suitable clearly marked container for disposal or reclamation in accordance with local regulations. Flush contaminated area with plenty of water. Do not flush away residues with water. Retain as contaminated waste.

7. HANDLING AND STORAGE

General Precautions : Contaminated leather articles including shoes cannot be decontaminated and should be destroyed to prevent reuse. Properly dispose of any contaminated rags or cleaning materials in order to prevent fires. Air-dry contaminated clothing in a well-ventilated area before laundering

Precautions for Safe Handling : Extinguish any naked flames. Do not smoke. Remove ignition sour Avoid sparks. Local exhaust ventilation is recommended. Avoid breathing vapours or contact with material. Only use in well ventilated areas. Wash thoroughly after handling. On guidance on selection of personal protective equipment see section 8 of this Safety Data Sheet.

Condition for Safe Storage : Store away from fire hazards area and away from sunlight. Extinguish any naked flames. Do not smoke.Remove ignition sources. Store indoor under well ventilated area.
