Particulate contamination
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.
