possible failure and is a possible environmental hazard. If the chiller would fail it would

leave the MRI without cooling for direct patient care and the MRI equipment. The

Chiller is located outside on the east side of the MRI building at the Des Moines, IA

VACIHCS. All work will be performed during after normal hours and or on the

weekend and must be coordinated with the COR at a minimum of 60 days prior
