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.
NOTE: This section defines the limits to help avoid IT equipment damage and/or failure from
particulates and gaseous contamination. If it is determined that levels of particulates or gaseous
pollution are beyond the limits specified below 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.
