You will certainly want to plan for the cleanup. If you have the luxury of being able to schedule some downtime, that is a bonus. You can use the same time to rearrange your equipment, move racks together to block airflow from the hot aisles into the cold aisles, etc.
If you don't have that luxury, then you may have to run on a redundant site for a while, or remediate portions of the data center at a time using your failover mechanisms. You will likely, however, be somewhat vulnerable without your primary or backup systems (depending on which you are remediating) so plan carefully. It may even be in your best interest to rent some temporary equipment to use during the fix. You can also use this time to test your disaster recovery plan.
