NEGATIVE ISOLATION ROOM STANDARDSCLEVELAND CLINICPURPOSEThis document was developed for Cleveland Clinic to provide a standard basis of design for allnegative isolation rooms. Detailed information including specifications is provided in thisdocument. Any variation from this standard shall be submitted and reviewed with ClevelandClinic Facilities and Engineering Group. This document is intended to be used for design ofall isolation rooms at Cleveland Clinic.GENERAL OVERVIEWNegative air pressure rooms shall be designed in accordance with the most recent edition of theGuidelines for Design and Construction of Health Care Facilities (currently 2010), Center forDisease Control and American Society for Heating, Refrigeration, and Air ConditioningEngineers (ASHRAE) standards. These guidelines and standards provide a safe environmentfor hospital staff treating patients that require an airborne infection isolation room, as well asprotecting the surrounding patients, general public, and staff outside the airborne infectionisolation rooms.In addition to the minimum criteria, other "architectural" recommendations of an isolationroom are needed. Features that make a room "airtight" are door sweeps, caulking windows,gasketed lighting fixtures, gasketed ceiling tiles (or solid ceilings), gasketed medical gas,electrical and data outlets, and sealing "unseen" holes and penetrations behind casework and inthe walls above the ceiling. These room construction items greatly affect the ability tomaintain room static pressure.Mechanical system features include room pressurization monitors connected to the BuildingAutomation System (BAS) and redundant exhaust fans. A connection to the BAS from theisolation room monitors alerts the engineering staff to problems which may be able to be fixedfrom the BAS computer. It also allows the staff to be proactive and identify problems beforethey cause alarms. This BAS feature automatically tracks and monitors the room pressuresand can provide printouts for inspectors wishing to check for room pressure compliance. Aredundant exhaust fan will allow the isolation rooms to stay in operation upon a failure of onefan or for maintenance. HEPA filters are required. HEPA filters may not be required if thefans are at the top of the building but this issue must be reviewed and approved by FacilitiesEngineering.All operations and maintenance personnel will need training in the use and maintenance of theisolation rooms. Site specific programming, alarms, procedures and maintenance scheduleswill need to be established along with updating or creating new operational procedures. Thecommissioning, training, and start-up will be done during and at the end of the project.
