2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
May cause irritation of the mouth, throat, and esophagus with nausea, abdomina discomfort, vomiting, diarrhea, dizziness, and drowsiness. Aspiration into the lungs may occur during ingestion or vomiting, resulting in lung injury. Eye
Causes moderate to severe irritation, experienced as discomfort or pain, excess blinking and tear production, with marked excess redness and swelling of the conjunctiva. Skin
Brief contact may cause slight irritation with itching and local redness. Prolonged or repated contact may cause defatting and drying of the skin. Inhaled
Causes irritation of the respiratory tract, experienced as nasal discomfort and discharge with chest pain and coughing. High concentrations of vapour may cause nausea, vomiting, headache, and dizziness. Loss of consciousness may occur. 2.2 Health Effects - Chronic
Skin contact may aggravate an existing dermatitis. Inhalation of material may aggravate asthma and inflammatory or fibriotic pulmonary disease.
2.3 First Aid
Swallowed
Do not induce vomiting. Do not give anything to drink. Obtain medical attention without delay.
Eye
Immediately flush eyes with water for and continue washing for at least 15 minutes. Do not remove contact lenses, if worn. Obtain medical attention without delay, preferably from an ophthalmologist.
Skin
Remove contaminated clothing. Wash skin with sopa and water. Obtain medical attention if irritation persists. Wash clothing before reuse.
Inhaled
Remove to fresh air. Give artificial respiration if not breathing. If breathing is difficult, oxygen may be given by qualified personnel. Obtain medical attention.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
There is no specific antidote. Treatment of overexposure should be directed at the control of symptoms and the clinical condition of the patient. Any material aspirated during vomiting may cause lung injury. Therefore, emesis should be considered necessary to evacuate the stomach contents, this should be done by means least likely to cause aspiration (eg. gastric lavage after endotracheal intubation).
2.6 Toxicity Data
Oral (rat) LD50: 2.90 - 6.34 ml/kg. Percutaneous (rabbit) : 12.6 g/kg/24hr killed 3/10; 6.3 ml/kg/24hr killed 1/4.

3. PRECAUTIONS FOR USE
3.1 Exposure Standards
TWA8 (ACGIH/MSHA) 200 ppm, 590 mg/m3. STEL (ACGIH/MSHA) 300 ppm, 885 mg/m3.
3.2 Engineering Controls
General (mechanical) room ventilation is expected to be satisifactory where this product is stored and handled in closed equipment. Special, local ventilation needed at points where vapours can be expected to escape to the workplace air.
3.3 Personal Protection
Use self contained breathing apparatus in high vapour concentrations. Use butyl gloves, monogoggles, and chemical apron.
3.4 Flammability
Flammable liquid. Warning: Sudden release of hot organic chemical vapours or mists from process equipment operating at elevated temperatures and pressure, or sudden ingress of air into vacuum equipment, may result in igntion without the presence of obvious igntion sources. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Keep container closed. Handle containers with care. Open slowly in order to control possible pressure release. Store in a cool, weel ventilated place away from incompatible materials. This material is not a static accumulator, but use proper grounding procedures. Do not pressurise, cut, heat, or weld containers. Empty product containers may contain product residue. Do not reuse empty containers without commercial cleaning or reconditioning.
4.2 Packaging / Labelling UN No. 1193 Class 3 Sub Risk None Allocated Hazchem Code 2[Y]E Pack Group II EPG No. 14 Shipping Name ETHYL METHYL KETONE (METHYL ETHYL KETONE) Hazard IRRITANT
Risk Phrases R11 Highly flammable. R36/37 Irritating to eyes and respiratory system.
Safety Phrases S2 Keep out of the reach of children. S9 Keep container in a well ventilated place. S16 Keep away from sources of ignition. S25 Avoid contact with eyes. S33 Take precautionary measures against static discharges.
4.3 Spills and Disposal
Spills
Clean-up personnel should wear full protective clothing including breathing apparatus. Eliminate sources of ignition. Warn occupants of downwind areas of fire and explosion hazard. Prevent liquid from entering sewers, watercourses or low areas. Keep public away. Shut off source if possible to do so without hazard. Advise police if substance has entered a watercourse or sewer or has contaminated soil or vegetation. Take measures to minimize the effect on the ground water.
Contain spilled liquid with sand or earth. Dilute contained spill with water. Recover by pumping (use an explosion proof or hand pump) or with a suitable absorbent. If liquid is too viscous for pumping, scrape up with shovels or pails and place in suitable containers for recycle or disposal.
Disposal
Empty drums should be taken for recycling, reovery or disposal through a suitably qualified or licensed contractor. Care should be taken to ensure compliance with national and local regulations. Product is not suitable for disposal by either landfill or via municipal sewers, drains, natural streams or rivers. Material is ashless and can be burned directly in appropriate equipment.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Vapours from this material may settle in low or confined areas or travel a long distance to an igntion source and flash back explosively. Shot off fuel to fire. If a leak or spill has not ignited, use water ot disperse the vapours and to protect men attempting to stop a leak. Either allow fire to burn under controlled conditions or extinguish with alcohol type foam or dry chemical. Try to cover liquid spills with foam. Keep fire exposed containers cool with water spray.
Extinguishing Media
Firefighters should wear full protective clothing including self contained breathing apparatus. Apply alcohol type or all purpose type foam by manufacturers recommended techniques for large fires. Use carbon dioxide or dry chemical media for small fires. 5 OTHER INFORMATION
