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.
