Use and Care Manual

Fire/Explosion Hazard
WARNING:
In use may form flammable/ explosive vapour-air mixtures.
When silica dust is dispersed in air, firefighters should wear inhalation protection as hazardous substances from the fire may
be adsorbed on the silica particles.
When heated to extreme temperatures, (>1700 deg.C) amorphous silica can fuse.
Combustible.
Slight fire hazard when exposed to heat or flame.
Heating may cause expansion or decomposition leading to violent rupture of containers.
On combustion, may emit toxic fumes of carbon monoxide (CO).
May emit acrid smoke.
Mists containing combustible materials may be explosive.
Combustion products include:
carbon dioxide (CO2)
silicon dioxide (SiO2)
other pyrolysis products typical of burning organic material.
May emit poisonous fumes.
May emit corrosive fumes.
WARNING
:
Long standing in contact with air and light may result in the formation
of potentially explosive peroxides.
