Schedule of Isolation Points (SOIP)
One component of a package of 10 key oversight documents for asset management.

The schedule of isolation points is an itemized list of the major shut off valves and other critical isolation points in a building. For example: our main water shutoff valve is in the P1 mechanical room and our main gas shut off is in the alleyway behind the building.  SOIP is typically 1-3 pages in length and it should be conspicuously posted on the wall in a convenient place such as the main mechanical room. It is an essential risk management tool for emergencies and a useful resource for regular maintenance.


Content of SOIP
The schedule of isolation points contains a concise list of the following information associated with some of the assets within a facility.
  • The names of the assets that have isolation (typically in the mechanical system and electrical system).
  • The locations of all shutoff (gas, water, power, etc)
  • The date of the last shutdown.
  • Procedures for shutdowns.
  • Contact persons who can assist with shutdowns.
  • Authorization or permission for shutdowns.
  • Any pertinent notes.
A spreadsheet template is provided here.


Importance of SOIP
The SOIP is a critical document in the OMSI and risk management plan. Listed below are some of the reasons why SOIP is essential for asset management. The first two items have to do with risk management while the second two items have to do with operational efficiency.

      Safety:
     Emergencies:
     Maintenance:
  • Some equipment must be shutdown on a seasonal basis. For example: Hosebib winterization every year and winterization of our irrigation sprinkler system.
  • Maintenance – we need to shut off equipment to purge, flush and scope
     Repairs & Renewals:
  • Isolation of equipment is necessary for repairs and renewals.
  • We need to shut things off to fix them.
The SOIP forms one of they reference documents for the Operations and Maintenance Support Information (OMSI).


A short story to illustrate
A pipe burst in one of the suites. Water was flooding into the suite and running down into floors below causing significant collateral damage. Owners were in a panic. Nobody knew how or where to turn off the water. When they finally found the valve, it was seized. It would not fully close as it had not been maintained for over 20 years. Water flooded into the elevator  shaft. Many, many thousands of dollars of damage could have been prevented had 5 minutes of maintenance been performed on the valve and had there been a valve chart in the building.


How to use the schedules to avoid this scenario:

      Before the event
  • Ensure that SOIP is up to date
  • Ensure that valves are being maintained in accordance with SOMI
      During the event
  • Go to SOIP to confirm location of valves. Or, go to the mechanical room and review the valve chart
  • Follow the shut off procedures
  • Call the service contractor  listed in SOSA to carry out the necessary repairs
      After the event
  • Record what happened in SOHE
