4. First aid measures General Inhalation Ingestion Skin Eyes Remove victim immediately from source of exposure. General first aid, rest, warmth and fresh air. Contact physician if symptoms appear. If breathed in, move person into fresh air. If not breathing give artificial respiration Consult a physician. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician. Wash the skin with plenty of water and soap. If skin irritation persists, consult a physician. Rinse immediately with plenty of water, also under the eyelids. Continue irrigation for several minutes while moving eyes to extreme positions. Consult a physician (ophthalmologist; risk of corneal damage). 5. Fire-fighting measures Suitable extinguishing media Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Special fire fighting procedures Move container from fire area if it can be done without risk. Cool containers exposed to flames with water until well after the fire is out. Avoid water in straight hose stream; will scatter and spread fire. Specific hazards Solvent vapours may form explosive mixtures with air. Vapour is heavier than air and may accumulate into hollows or confined spaces. Special protective equipment for firefighters Wear personal protective equipment. Wear self contained breathing apparatus for fire fighting. 6. Accidental release measures Personal precautions Environmental precautions Methods for cleaning up Avoid inhalation of gases. Evacuate personnel to safe areas. Avoid contact with skin and eyes. Wear personal protective equipment. Avoid sparks, flames, heat and smoking. Ventilate. Prevent product from entering drains or environment. Extinguish all ignition sources. Avoid sparks, flames, heat and smoking. Ventilate. Absorb in vermiculite, dry sand or earth and place into containers. Collect and reclaim or dispose in sealed containers in licensed waste. Inform authorities if large amounts are involved. Dispose of in accordance with local regulations. Safety Data Sheet Methyl ethyl ketoxime (MEKO) Page 2 of 6
7. Handling and storage Storage Handling Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Avoid contact with skin and eyes. Avoid inhalation of vapour or mist. Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge. 8. Exposure controls/personal protection Personal protective equipment Respiratory protection Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Hand protection The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it. Handle with gloves. Eye protection Face shield and safety glasses Skin and body protection Choose body protection according to the amount and concentration of the dangerous substance at the work place. Hygiene measures Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday. 9.
