2. HEALTH INFORMATION

·Eye contact

Liquid is slightly to to severly irritating to the eyes. Vapors are also irrit·Skin contact

Liquide is slightly to moderately irritating to skin. Prolonged or repeated liquidcan result in defatting and drying of the skin which may result in skin irritadermatitis. ·Inhalation

Vapors are moderately TOXIC; may produce CNS depression. Vapors May also irritate respiratory tract. ·Ingestion

Liquide is moderately toxic and may be harmful if swallowed; May produce CNS depMay also cause irritation to upperdigestive tract. ·Signs and symptoms

Registration number CAS No. : 108-10-1

Irritation as noted above. Early to moderate CNS(Central Nervous System) depression may be evidence by giddiness, headache, dizziness and nausea; In extreme cases, unconsciousness and death may occur.

·Aggravated medical conditions

Preexisting eye, skin and respiratory disoders may be aggravated by exposure to Methyl Isobutyl Ketone

3. EMERGENCY AND FIRST AID PROCEDURES

·Eye contact

Immediately flush eyes with plenty of water for at least 15 minutes while holding eyelids open. Get medical attention. ·Skin contact

Flush skin with water while removing contaminated clothing and shoes. If irritation occurs, get medical attention. Do no reuse clothing or showes until cleaned. ·Inhalation

Remove victim to fresh air and provide oxygen if breathing is difficult. Get artificial respiration if not breathing. Get medical attention. ·Ingestion

do not give liquids if victim is unconscious or very drowsy. Otherwise, give no more than 2 glasses of water and induce vomiting by giving 30cc(2 tablespoons) syrup of IPECAC.* If IPECAC is unavailable, give 2 glasses of water and induce vomiting by touching finger to back of victim's throat. Keep victim's head below hips while vomiting. Get medical attention.

·Note to physician

*Note to physician: If victim is a child, give no more than 1 glass of water and 15 cc(1 tablespoon) syrup of IPECAC. If symptoms such as loss of gag reflex, convulsions or unconsciousness occur before emesis. Gastric lavage should be onsidered following intubation with a cuffed endotracheal tube.

4. SUPPLEMENTAL HEALTH INFORMATION

Although the significance to humans is unknow. In male rats exposed by inhalation to vapors(up to 100 ppm) for 90 days. Evidence of slight kidney damage was observed.

5. FIRE AND EXPLOSION HAZARDS

·Extinguish media

Use water fog, \"Alcohol\" foam, dry chemical or CO2

·Special fire fighting procedures and precautions

Warning, Flammable, Clear fire area of unportected personnel. Do no enter confined fire space without full bunker gear(Helmet with face shield, bunker coats, gloves and rubber coats), including a positive pressure NIOSH approved self-contained breathing apparatus. Cool fire exposed containers with water.

6. ENVIRONMENTAL PROTECTION

·Spill or leak procedures

Warning. Flammable, Eliminate all ignition sources, Handling equipment must be grounded to prevent sparking. Large spills :

Evacuatethe hazard area of unprotected personnle. Wear appropriated respirator and protective clothing. Shut off source of leak only if safe to do so, dike and contain. If vapor cloud forms, water fog may be used to suppress; contain run-off.

Remove the vacuum trucks or pump to storage/salvage vessels. Soak up residue with an absorbent such as clay, sand or other suitable material; Place in non-leaking containers for proper disposal. Flush area with water to remove trace residue; Dispose of flush solutions as above. Small spills :

Take up with an absorbent material and place in non-leaking containers; Seal tightly for proper disposal.

7. PERSONNEL PROTECTION

·Respiratory protection

Avoid prolonged or repeated breathing of vapors. If exposure may or does exceed occupational exposure limits, use a NIOSH-APPROVED respirator to prvent overexposure. OSHA has extablished transitional occupational limits for this product and/or components of this product.

·Protective clothing

Avoid contact with eyes, or prolonged/repeated contact with skin. Wear chemical gogles if there is likelihood of contact with eyes. Wer chemical resistant gloves and other clothing as required to minimized contact. Test data indicate the best protection is provided by polyvinyl alcohol gloves. ·Additional protective measures

Use explosion-proof ventilation as required to control vapor concentration. A

11. SPECIAL PRECAUTIONS

Keep liquid and vapour away from heat, sparks and flame. Surfaces that are sufficiently hot may ignite even liquid product in the absence of sparks or flame. Extinguish pilot lights, cigarettes and turn off other sources of ignition prior to use and untial all vapors are gone. Vapors may accumulate and travel to ignition sources distant from the handling site; flash fire can result. Keep containers closed when not in use. Use with adequate ventilation.

Containers, even those that have, been emptied, can contain explosive vapors. Do not cut, drill, grind, weld or perform similar operations on or near containers. Static electrical may accumulated equipment.

Do not pressurize drum containers to empty them.

Wash with soap and water before eating, smoking, applying cosmetics, or using toilet

facilities

Launder contaminated clothing before reuse.
