Particulate and gaseous contamination specifications

The following table defines the limitations that help avoid any equipment damage or failure from particulates and gaseous
contamination. If the levels of particulates or gaseous pollution exceed the specified limitations and result in equipment damage
or failure, you may need to rectify the environmental conditions. Re-mediation of environmental conditions is the responsibility
of the customer.
This section defines the limits to help avoid IT equipment damage and/or failure from particulates and gaseous
NOTE:
contamination. If it is determined that levels of particulates or gaseous pollution are beyond the limits specified in the
following table and are the reason for the damage and/or failures to your equipment, it may be necessary for you to
re-mediate the environmental conditions that are causing the damage and/or failures. Re-mediation of environmental
conditions will be the responsibility of the customer.
