How safe is FAST-ACT®?
FAST-ACT has undergone rigorous toxicity evaluation (dermal, ocular, oral
and inhalation toxicity) by third party laboratories which revealed no safety
hazards.
FAST-ACT is made of the same materials that are found in your food and
other household products.
The manufacturing approach enhances the capability of these everyday
materials turning them into powerful, chemical neutralizing products.
NIOSH currently has no recommended exposure limit for TiO2. For users
with dust sensitivities, a standard NIOSH approved N95 Respirator will
suffice.

Safety – Nano?
•
•
•
How are Timiloin’s materials different than nanoparticles?
The commonly accepted definition for nanotechnology or a nanomaterial is
one that is 100 nanometers or less.
FAST-ACT components are not nanoparticles like nanotubes or other
shapes. The component materials of FAST-ACT (magnesium oxide and
titanium dioxide) have crystallite sizes engineered to be less than 10 nm.
However, the large surface energy of these nanocrystals causes them to
form extremely porous agglomerates that are much larger. FAST-ACT is
composed of micron sized agglomerates of nanocrystals which are 30-50
times larger than nanoparticles. Because of this, there is no inherent danger
associated with the particle size.

Safety – Metal Oxide?
•
•
What is a metal oxide?
Metal oxides are generally safe materials that are commonly used in
cosmetics, food and many other products we use daily.
•
The metal oxides in FAST-ACT have a much higher affinity for capturing
and neutralizing chemicals due to the unique way they are manufactured.
The process results in a high surface area material which allows for better
absorption of chemicals. Chemicals and pollutants adsorbed by the product
are destroyed and cannot escape.

• First Aid Measures
–
Skin: In case of skin contact, flush with copious amounts of water for at least 15
minutes, remove contaminated clothing and shoes.
–
Inhalation: If inhaled, remove to fresh air. If breathing is difficult, give oxygen. If
not breathing, give artificial respiration.
–
Eyes: In case of contact with eyes, flush with copious amounts of water for at
least 15 minutes. Assure adequate flushing by separating eyelids with fingers.
–
Ingestion: If swallowed, wash out mouth with water provided that person is
conscious. Seek medical attention.
–
Internal contact via wounds: Flush wound with water.

• Fire-Fighting Measures
– FAST-ACT is not flammable, combustible, or
explosive.
– May emit toxic fumes at temperatures greater than
2800°C.
(2800°C = 5072°F)
– The formulation may be exposed to water, carbon
dioxide, dry chemical, and foam-extinguishing agents
as necessary during fire-fighting operations.

• Accidental Release Measures
– A spill of FAST-ACT poses hazards similar to other nuisance dusts.
– Vacuum or sweep up material and place in suitable container. Avoid
generating dusty conditions, provide adequate ventilation.
Serving Customer Needs Through Advanced Chemistry
MSDS - Section 7
• Handling and Storage
– Store in sealed containers to avoid slow reactions
with carbon dioxide and moisture in air.

MSDS - Section 8
• Exposure Controls and Personal Protection
– As with any nuisance dust, the use of NIOSH approved
respirators is recommended in cases where prolonged exposure
is expected or exposure is above the PEL (Permissible Exposure
Limit).
– Mechanical ventilation of work areas is recommended when
prolonged exposure to dust may be present.
– Workers should wash exposed skin thoroughly after any possible
exposure.
– FAST-ACT can adsorb moisture and natural oils from the surface
of the skin during prolonged exposure.
– Prolonged exposure should be avoided by wearing suitable
protective gloves and clothing.
