with water or humid air.
Normal Exposure -- Methyl Ethyl Ketoxime: Skin, Eye
Overexposure -- Methyl Ethyl Ketoxime: Male rodents exposed to
MEKO vapors over their lifetime developed
liver cancer. Additional testing is planned
to determine any relevance to humans.
CARCINOGENICITY...
NTP? N/E | IARC Monographs? N/E | OHSA? NO
EFFECTS OF OVEREXPOSURE
Eyes: Direct contact can cause irritation, redness and tearing.
Skin: Prolonged or repeated contact can cause moderate irritation.
Oximes are possible skin sensitizers.
Inhalation: Excessive inhalation of vapors can cause respiratory
irritation, headache, and drowsiness. High concentrations
of vapors are anesthetic and may have blood oxygen effects.
Ingestion: Small amounts transferred to the mouth during use will
not injure. Large amounts could injure slightly.
FIRST AID MEASURES
Eyes: Flush with large amounts of water for at least 15 minutes
lifting eyelids occasionally; get prompt medical attention
Skin: Wash thoroughly with soap and water; apply a mild skin

cream.
Inhalation: Remove affected person to fresh air; if breathing
is difficult, administer oxygen, get medical attention.
Ingestion: DO NOT INDUCE VOMITING! Get immediate medical atten-
tion.
Cured sealant is non-hazardous.
SECTION VI - STABILITY AND REACTIVITY
Stability: This product is stable
Hazardous Polymerization: Hazardous polymerization will not occur
INCOMPATABILITY:
Strong oxidizing agents cause a reaction. Air and moisture
cause curing and release of Methylethyl Ketoxime.

RESPIRATORY PROTECTION:
Use NIOSH approved respiratory protection if TLV is exceeded.
VENTILATION:
Use only in well ventilated areas.
Provide sufficient mechanical (general and/or local exhaust)
ventilation to maintain exposure below TLV.
PROTECTIVE CLOTHING:
Rubber gloves should be worn.
EYE PROTECTION:
Chemical goggles should be worn.
HANDLING AND STORAGE PRECAUTIONS:
Keep container closed when not in use.
Avoid contact with eyes and skin. Do not handle contact lenses
