CAS #.................... 78-93-3 Methyl Ethyl Ketone - 100%
Clear, colorless liquid. Flash point -7°C Extremely flammable liquid and vapor. Potential health effects (acute and chronic): Symptoms of exposure: Effects of eye exposure: Causes eye irritation. May result in corneal injury. Effects of skin contact: May be absorbed through the skin in harmful Amounts. Prolonged and/or repeated contact may cause irritation and/or dermatitis. Effects of ingestion: May cause irritation of the digestive tract. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure. Effects of inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. Causes respiratory tract irritation. Irritation may lead to chemical pneumonitis and pulmonary edema. May produce numbness in the extremities. Target Organs: Central nervous system, eyes, skin, mucous membranes. Routes of entry: Inhalation, ingestion or eye or skin contact.
Emergency and first aid procedures:
Get medical assistance for all cases of over-exposure.
Skin: Get medical aid. Immediately flush skin thoroughly with water
for at least 15 minutes. Remove contaminated clothing and shoes.
Wash clothing before reuse.
Eyes: Get medical aid immediately. Immediately flush thoroughly with
water for at least 15 minutes, occasionally lifting the upper and
lower eyelids. Do not allow victim to rub or keep eyes closed.
Inhalation: Get medical aid immediately. Remove to fresh air immediately.
Artificial respiration if breathing has stopped. If breathing is difficult,
give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased,
apply artificial respiration using oxygen and a suitable mechanical device such
as a bag and a mask.
Ingestion: Do NOT induce vomiting. If conscious and alert, give 2-4 cupfuls of
milk or water. Never give anything by mouth to an unconscious person. Get medical
aid immediately.
Notes to Physician: Treat symptomatically and supportively.
Flash Point.................... -7°C
Autoignition Temperature....... 404°C
Explosion Limits: Lower 1.4 vol % at 200°F
Upper 11.4 vol % at 200°F
Fire Extinguishing Media:
For small fires use dry chemical, CO2, or "alcohol" foam, water spray to
cool fire-exposed containers and disperse vapor; water on fire itself may
be ineffective. For large fires, use water spray, fog or alcohol-
resistant foam. Do NOT use straight streams of water. Cool containers
with flooding quantities of water until well after fire is out.
Firefighting Procedure:
Wear self-contained breathing apparatus in pressure-demand full
protective gear.
Fire and explosion hazards:
Vapor can travel distance to ignition source and flash back. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Can release vapors that form explosive
mixtures at temperatures above the flashpoint. Use water spray to keep
fire-exposed containers cool. Water may be ineffective. Material is
lighter than water and a fire may be spread by the use of water. Vapors
may be heavier than air. They can spread along the ground and collect in
low or confined areas. May polymerize explosively when involved in a
fire. Containers may explode when heated.
Spill Response:
Evacuate the area of all unnecessary personnel.
Wear suitable protective equipment listed under exposure/personal
Protection, including self contained breathing apparatus. Eliminate any
ignition sources until the area is determined to be free from explosion
or fire hazards. Contain the release and eliminate its source, if this
can be done without risk. Absorb spill with an absorbent, non-combustible
material such as earth, sand or vermiculite. Scoop up with non-sparking
tool and containerize for proper disposal. Comply with federal, state,
and local regulations on reporting release. Refer to regulatory
information for reportable quantity and other regulatory data.
Disposal considerations:
EPA (Environmental Protection Agency) waste numbers:
CAS# 78-93-3 - waste number U159 (Ignitable waste, Toxic waste)
Handling: Use only in a well-ventilated area. Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin and clothing. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof = equipment. Avoid contact with heat, sparks and flame. Empty containers may contain residue - do not pressurize, or expose empty containers to heat, sparks or open flames. Do not take internally. Eye wash and safety equipment should be readily available. Storage: Keep away from sources of ignition. Store in a flammables area. Store in cool, dry well ventilated area.
An eyewash facility and a safety shower should be available. Use adequate
general or local exhaust ventilation to keep airborne concentrations below
the permissible exposure limits.
