The small light particles (<5um) normally invisible to the naked eye are commonly called
Airborne Molecular Contaminants (AMCs). They can become suspended for hours in the
surrounding environment where they are quickly spread, polluting the atmosphere.

The effectiveness of your critical environment is threatened by the continuous
movement of contaminants. High levels of air-borne contamination can lead to microbial
corruption of cleanroom surfaces.

By their very nature, the movement of airborne contaminants is volatile, which makes
detection and prevention measures difficult. Once turbulence stops, airborne
contaminants fall due to gravity and/or airflow. If they fall onto an unprotected floor
they are free to rise as a result of vortices created by the movement of personnel and
wheeled traffic.

Contaminants are generated by people, process, facilities and equipment, and must be
continually controlled and removed from the air.

Using Dycem inside the critical area adjacent to products and processes dramatically
reduces airborne contaminants by up to 60%.

Floor level contamination

80% of contamination entering your critical environment does so, on feet or wheels.
(Source: 3M). Therefore, controlling contamination and cross contamination at or near
floor level is an essential and fundamental part of any integrated risk management
policy.

If left uncontrolled, floor level contamination can be redistributed into the air by vortices
caused by any movement of a body through the critical environment. In addition,
unprotected flooring enables contaminants to be picked up on shoes and on the wheels
of carts where they are tracked into the critical area. The effect of this can be seriously
destructive. Since 80% of all contamination enters an environment at floor level, without
an effective control method you could be quadrupling the viable contamination in the
air.

Using Dycem CleanZone Technology prior to all entrances to critical areas will prevent up
to 99.9% of foot and wheel borne contaminants from entering the critical area.
