3. HAZARDS IDENTIFICATION
------------------------------------------------------------------------------
1 EMERGENCY OVERVIEW:
WARNING!
May cause skin, eye, and stomach irritation.
Harmful if swallowed, inhaled, or absorbed through skin.
May cause central nervous system depression.
Refer to other MSDS sections for detailed information.
Ammonia odor
Translucent solid
POTENTIAL HEALTH EFFECTS:
INGESTION:
May cause stomach discomfort.
May be harmful if swallowed.
May cause central nervous system effects.
May cause gastrointestinal irritation, nausea, vomiting, and
diarrhea.
Not an expected route of exposure.
SKIN CONTACT:
Uncured product contact will irritate lips, gums and tongue.
Uncured product contact may irritate the skin.
May cause mild skin irritation.
May be absorbed through skin and produce effects as listed
COPYRIGHT GENERAL ELECTRIC CO. page: 2
under "Ingestion".
INHALATION:
Causes mild respiratory irritation.
Applies only in uncured state.
May also cause other effects as listed under "Ingestion".
EYE CONTACT:
Uncured product contact irritates eyes.
May cause mild eye irritation.
MEDICAL CONDITIONS AGGRAVATED:
Pre-existing skin or respiratory diseases.
SUBCHRONIC (TARGET ORGAN) EFFECTS:
Central nervous system
Skin
CHRONIC EFFECTS/CARCINOGENICITY:
This product or one of its ingredients present 0.1% or more
is NOT listed as a carcinogen or suspected carcinogen by
NTP, IARC, or OSHA.
PRODUCTS/INGREDIENTS
This space reserved for special use.
PRINCIPLE ROUTES OF EXPOSURE:
Oral.
Dermal - skin.
Eyes.
Inhalation.
OTHER:
This product contains methylpolysiloxanes which can generate
formaldehyde at approximately 300 degrees Fahrenheit (150'C)
and above, in atmospheres which contain oxygen. Formaldehyde
is a skin and respiratory sensitizer, eye and throat irritant,
acute toxicant, and potential cancer hazard. An MSDS for
formaldehyde is available from GE Silicones.

SPECIAL FIREFIGHTING PROCEDURES:
Firefighters must wear NIOSH/MSHA approved positive pressure
self-contained breathing apparatus with full face mask and full
protective clothing.
------------------------------------------------------------------------------
6. ACCIDENTAL RELEASE MEASURES
------------------------------------------------------------------------------
1
ACTION TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED:
Wipe, scrape or soak up in an inert material and put in a
container for disposal.
Wash walking surfaces with detergent and water to reduce slip-
ping hazard.
Wear proper protective equipment as specified in the protective
equipment section.
------------------------------------------------------------------------------
7. HANDLING AND STORAGE
------------------------------------------------------------------------------
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE:
Keep container closed when not in use.
Avoid contact with skin and eyes.
Remove contact lenses before using sealant. Do not handle
lenses until all sealant has been cleaned from the finger-
tips, nails and cuticles. Residual sealant may remain on
fingers for several days and transfer to lenses and cause
severe eye irritation.
Use mechanical ventilation to stay below TLV of 25 ppm ammonia.
Store away from heat, sources of ignition, and incompatibles.
Product releases methanol during application and curing.
COPYRIGHT GENERAL ELECTRIC CO. page: 5
Keep away from children.
------------------------------------------------------------------------------
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
------------------------------------------------------------------------------
ENGINEERING CONTROLS:
Showers.
Eyewash stations.
See "Ventilation" below.
RESPIRATORY PROTECTION:
If exposure limits are exceeded or respiratory irritation is
experienced, NIOSH/MSHA approved respiratory protection should
be worn. Supplied air respirators may be required for
non-routine or emergency situations. Respiratory protection
must be provided in accordance with OSHA regulations (see 29
CFR 1910.134).
PROTECTIVE GLOVES:
Cloth gloves.
EYE AND FACE PROTECTION:
Safety glasses.
OTHER PROTECTIVE EQUIPMENT:
Wear eye protection and protective clothing.
VENTILATION:
Ventilation and other forms of engineering controls are
preferred for controlling exposures. Respiratory protection
may be needed for non-routine or emergency situations.
