Particulate and gaseous contamination specifications

The following table defines the limitations that will help avoid any damages to the IT equipment and/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.
