PRODUCT NAME : GREASE - SILICONE HIGH VACUUM
Ingestion/Oral Small amounts transferred to the mouth by the fingers during use should not injure.
Effects: Swallowing large amounts may cause digestive discomfort.
Inhalation Effects: Extremely low volatility makes inhalation an unlikely hazard in normal use at room
temperature.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: None known.
NFPA Hazard codes HMIS Hazard codes Rating System
Health 1 Health 1 0 = No Hazard
Flammability 1 Flammability 1 1 = Slight hazard
Instability 0 Reactivity 0 2 = Moderate Hazard
3 = Serious Hazard
4 = Severe hazard
4. First Aid Measures
Immediately flush with water.
Eyes:
No first aid should be needed.
Skin:
No first aid should be needed.
Ingestion/Oral:
No first aid should be needed. If high concentrations of mists or fumes are inhaled, remove
Inhalation:
to fresh air. If breathing problems occur, a qualified individual should administer oxygen or
artificial respiration as indicated. Seek immediate medical attention.
Treat symptomatically.
Other Information:
5. Fire Fighting Measures
Extinguishing Media: Carbon dioxide, dry powder, foam, fine water spray.
Fire and Explosion Hazard: No known unusual hazards. Hazardous decomposition products: silicon dioxide
(silica), carbon monoxide, carbon dioxide and traces of incompletely burned
carbon products. The product may emit formaldehyde vapours at temperatures
above 150oC/302oF in the presence of air. Direct water stream may cause violent
frothing.
Special Protective Equipment In confined spaces or for large fires, fire fighters should wear a self-contained
for Fire Fighters: breathing apparatus (SCBA) which meets appropriate standards operated in
positive pressure mode, and full turnout gear.
For Flammability Properties - see Section 9

6. Accidental Release Measures
Spillage: Use personal protection equipment recommended in Section 8. Prevent material from spreading. Clean
up spilt material with a suitable absorbent and dispose of appropriately with regard to laws and regulations relating
to material release and disposal. Clean area since silicone materials, even in small quantities, may present a slip
hazard. Final cleaning may require use of steam, solvents or detergents.
7. Handling and Storage
Handling: General ventilation is required. Avoid eye contact.
Storage: No special measures required. Store away from oxidising materials.
