Ingestion/Oral Small amounts transferred to the mouth by fingers during use should not injure. Swallowing
Effects: large amounts may cause digestive discomfort.
Inhalation Effects: Ambient temperature: no irritation of respiratory passages. No injury is likely from relatively
short exposures (<8h). Mist may cause temporary discomfort.
Elevated temperatures: If heated in air above 150oC/302oF, the product may emit
formaldehyde vapours and trace amounts of benzene.
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
Reactivity 0 Reactivity 0 2 = Moderate Hazard
3 = Serious Hazard
4 = Severe hazard
4. First Aid Measures
Flush with water for 15 minutes. If irritation persists, seek medical attention.
Eyes:
Flush with water for 15 minutes.
Skin:
No first aid should be needed.
Ingestion/Oral:
No first aid should be needed. If overcome by fumes produced at elevated temperatures,
Inhalation:
remove 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, foam, dry powder or fine water spray. Water can be used to cool
fire exposed containers.
Fire and Explosion Hazard: No unusual hazards known. Hazardous decomposition products: silicon dioxide,
carbon dioxide and traces of incompletely burned hydrocarbons. If heated in air
above 150oC/302oF, the product may emit formaldehyde vapours and trace
amounts of benzene.
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. Wear skin protection adequate to
protect from thermal decomposition products.
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 suitable equipment (e.g. cloth, mop, absorbent) and dispose of saturated absorbent or cleaning
materials appropriately. Store recovered material in suitable container. 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: No special measures required. Avoid eye contact.
Storage: No special measures required.
