Fire Fighting Instructions: Water may be ineffective but should be used to cool fire-exposed structures and
vessels. Use water spray for large fires. Water spray can be used to reduce the
intensity of flames and to dilute spills to a non-flammable mixture. Keep personnel
removed from and upwind of fire. If potential for exposure to vapors or products of
combustion exists, wear full fire fighting turnout gear and NIOSH approved self-
contained breathing apparatus. Oxidizing chemicals may accelerate the burning
rate in a fire situation. Vapor is heavier than air and can travel considerable
distance to a source of ignition and flashback.
Fire Fighting Vapors and combustion gases can be controlled using a water fog stream.
Environmental Concerns: Thoroughly decontaminate bunker gear and other fire-fighting equipment before
re-use.

Spill or Leak Instructions Eliminate ignition sources. See Section 8 for appropriate personal protective
equipment. Contain spill with dikes of soil or nonflammable absorbent to minimize
contaminated area. Water fog stream may reduce vapors. If fire potential exists,
blanket spill with alcohol type aqueous film-forming foam or use water fog stream
to disperse vapors. Avoid run-off into storm sewers and ditches leading to
waterways. If required, notify state and local authorities. Place leaking containers
in well-ventilated area. Clean up small spills by using a nonflammable absorbent or
flushing sparingly with water. Contain larger spills with nonflammable diking or
absorbent. Clean up by vacuuming or sweeping.
Within the United States, call the National Response Center (800-424-8802) and
appropriate state and local authorities if the quantity released over 24 hours is
equal to or greater than the reportable quantity listed below: par 5,000 lbs. of the
material as is, based on a Reportable Quantity of 5,000 lbs. for methyl ethyl
ketone.
Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind;
keep out of low areas. Isolate for 800 meters or 0.5 miles in all directions if tank,
rail car, or tank truck in involved in fire. Evacuate downwind areas as conditions
warrant to prevent exposure and to allow vapors or fumes to dissipate. Spills may
expose downwind areas to toxic or flammable concentrations over considerable
distances in some cases.
7. Handling and Storage
Handling: Use with adequate ventilation. Keep containers closed when not in use. Always
open containers slowly to allow any excess pressure to vent. Avoid breathing
vapor. Avoid contact with eyes, skin or clothing. Wash thoroughly with soap and
water after handling. Decontaminate soiled clothing thoroughly before re-use.
Destroy contaminated leather clothing.

MSDS number: 61
Material number: MSDS-061
Published date: 03/23/2001(V3)
Engineering Controls: General or dilution ventilation is frequently insufficient as the sole means of
controlling employee exposure. Local ventilation is usually preferred. Explosion-
proof equipment (for example fans, switches, and grounded ducts) should be used
in mechanical ventilation systems.
A safety shower and eyebath should be readily available.
Protective Equipment
Skin protection: Wear impervious clothing and gloves to prevent contact. Butyl rubber is
recommended. Other protective material may be used, depending on the
situation, if adequate degradation and permeation data is available. If other
chemicals are used in conjunction with this chemical, material selection should be
based on protection for all chemicals present.
Eye/face protection: Wear chemical goggles when there is a reasonable chance of eye contact.
Respiratory protection: Based on workplace contaminant level and working limits of the respirator, use a
respirator approved by NIOSH. The following is the minimum recommended
equipment for an occupational exposure level. To estimate an occupational
exposure level see Section 3, Section 8 and Section 11.
For concentrations > 1 and < 10 times the occupational exposure level: Use air-
purifying respirator with full facepiece and organic vapor cartridge(s) or air-purifying
full facepiece respirator with an organic vapor canister or a full facepiece powered
air-purifying respirator fitted with organic vapor cartridge(s). The air purifying
element must have an end of service life indicator, or a documented change out
schedule must be established. Otherwise, use supplied air.
For concentrations more than 10 times the occupational exposure level and less
than the lower of either 100 times the occupational exposure level or the IDLH:
Use Type C full facepiece supplied-air respirator operated in positive-pressure or
continuous-flow mode.
For concentrations > 100 times the occupational exposure level or greater than the
IDLH level or unknown concentrations (such as in emergencies): Use self-
contained breathing apparatus with full facepiece in positive-pressure mode or
Type C positive-pressure full facepiece supplied-air respirator with an auxiliary
positive-pressure self-contained breathing apparatus escape system.
For escape: Use self-contained breathing apparatus with full facepiece or any
respirator specifically approved for escape.

11. Toxicological Information
Component Toxicological Information
Component METHYL ETHYL KETONE
Acute Exposure: Excessive exposure to MEK leads to depression of the central
nervous system, shown by loss of coordination, reflexes and consciousness.
Oral: Slightly toxic; oral LD50 (rat) = 2.7-5.6 g/kg .
Inhalation: Slightly toxic; inhalation LC50 (rat) is estimated to be > 5000 ppm for a
6 hr. vapor exposure based on the lack of mortality in a repeated exposure study
at this level. Other earlier studies exist, but do not meet current scientific
guidelines. Causes irritation of the nasal passages and throat.
Skin: Slightly toxic; Dermal LD50 (rabbit) = 5.0 - 13 g/kg. Can cause mild to
moderate skin irritation (reddening and swelling). Repeated or prolonged contact
can cause drying of the skin and dermatitis. Not a skin sensitizer based on human
patch test.
Eye: Liquid and vapor can cause severe eye irritation.

MSDS number: 61
Material number: MSDS-061
Published date: 03/23/2001(V3)
Mutagenicity: MEK has been shown to be without genotoxic activity in a variety of
in vitro and in vivo tests. Among the tests which produced negative results are
assays for point mutation (e.g., Ames test and mouse lymphoma), chromosomal
aberration (rat liver cells in vitro and mouse bone marrow in vivo), DNA damage
(unscheduled DNA synthesis in rat hepatocytes,), and morphologic transformation
(BALB 3T3 morphologic transformation assay). There was some evidence that
MEK induced aneuploidy in yeast, but this does not appear to be biologically
important since negative results were obtained in a mouse micronucleus test.
Carcinogenicity: No toxicologic studies. Not listed by IARC, NTP or OSHA.
Reproductive/Developmental Effects: No human studies have been reported.
An initial inhalation study with rats indicated fetotoxicity (e.g., delayed fetal
development) and possible teratogenicity at 3000 ppm. However, a
comprehensive follow-up study in rats showed only slight fetotoxicity accompanied
by maternal toxicity at 3000 ppm, but no teratogenic effects. No significant
differences were seen between rats exposed to 1000 ppm or 400 ppm MEK and
the control. Likewise an inhalation study with mice showed only fetotoxicity at
3000 ppm and no effects at 1000 ppm or 400 ppm MEK.
The fetotoxicity in mice also was accompanied by maternal toxicity in mice at 3000
ppm. Since effects reported for the fetus (rats & mice) occurred only at dose
levels where maternal toxicity was evident and are, therefore, considered
secondary outcomes from the maternal toxicity, methyl ethyl ketone is concluded
not to be a developmental toxicant.
Other Effects: MEK is not neurotoxic. It has been shown to potentiate the
neurotoxic effects of hexane, 2,5-hexanedione and methyl-n-butyl ketone. MEK
has also potentiated the liver toxicity of halogenated solvents (e.g., chloroform and
carbon tetrachloride) in animal studies.
Repeated Exposure: Male and female rats exposed to 0, l250, 2500 or 5000 ppm
MEK in air for 6 hrs./day, 5 days/week for 90 days failed to demonstrate
pathological changes attributable to MEK in the organs and tissues studied. Other
studies conducted in rats and on other species at lower exposure levels had
similar results. A dose-related increase in absolute and relative liver weights was
statistically significant at the 5000 ppm exposure level. These effects are
considered adaptive in nature.

Component Ecological Information
Component METHYL ETHYL KETONE
Ecotoxicity: Methyl ethyl ketone has low acute toxicity to fish (LC50 range -
4,600 - 5,640 ppm) and aquatic invertebrates (EC50 range = 1,950 - 8,890 ppm).
At above 100 ppm it may inhibit the growth of blue-green algae but such
concentrations are unlikely to be reached except for short periods following
accidental discharge. A concentration of 900 ppm of MEK in water caused a 50%
inhibition of the germination of lettuce (lactuca sativa) seeds.
Environmental Fate:
Degradation:
Biodegradation: Extensive data demonstrate that MEK is readily biodegradable.
Determinations in freshwater and seawater demonstrated that the BOD was a high
percentage of the theoretical oxygen demand. Studies on activated sludge
showed that MEK is easily degraded and is not toxic to sludge microorganisms in
concentrations up to 800 ug/liter. Photodegradation - Although MEK is less
reactive in smog than many other organic chemicals, it does undergo significant
photodecomposition probably because of a combination of direct photolysis and
OH radical reactions. In the presence of 5 ppm NO, and with 35-40% relative
humidity and 10 ppm MEK, a photodecomposition half-life of 9.8 hours was found.
The half-life of MEK calculated in urban conditions is likely to be about 5.5 hours.
Bioaccumulation: No direct information is available on the ability of MEK to
accumulate in biological material. Its high water solubility, rapid degradation by
aquatic bacteria, and low octanol-water partition coefficient of 0.26 suggest that it
is unlikely to concentrate in aquatic species. Metabolic studies in man
demonstrate that concentrations likely to be present in the environment will not
lead to accumulation in human tissues.
