Safe first checks and escalationSchedule 01 of 017 rows6 columns
| Symptom (zone and asset) | Safe first checks | Authorised action | Stop - do not proceed if | Success check | Escalate to and drawing or document |
|---|---|---|---|---|---|
| Alarm and project isolation recorded - affected zone asset | Keep clear of water near electrics; identify flat or riser | Leave the recorded isolation state unchanged and call the front desk | Water is near electrics or the source is not visible | Flow stops and the project isolation state is recorded | 24 hour line - EB-A-GF-01 |
| Alarm and expected project isolation did not occur - affected zone asset | Observe visible indication and isolation state only | Call the 24 hour line; operator follows the controlled local-then-riser route | A control resists, access is unsafe or source is unclear | Lowest safe project isolation stops flow | 24 hour line - EB-A-WS-02 |
| Project isolation recorded but no visible water - affected zone | Check accessible dry areas and asset identity | Keep isolated pending competent inspection | Changing state could release concealed water | Cause is found and area remains safe | Technical support - project records |
| Water restored but alarm repeats - affected zone sensing point | Stop after the first repeat alarm and record the visible indication | Leave the controlled local isolation unchanged and escalate | Any repeat alarm occurs | System remains safely isolated without further action | 24 hour line - EB-A-CS-03 |
| Project asset has no visible indication - affected zone | Check only the visible indication and safe local supply state | Keep zone under observation and call support | Electrical access or live work would be needed | Competent person records the restored normal indication | Technical support - controlled document register |
| Project register unavailable but local state appears normal - affected zone | Confirm the visible local indication and recorded normal isolation state | Use the controlled offline evidence and report the register fault | Local state is abnormal or uncertain | Local project state remains normal and the fault is logged | Technical support - current manual issue |
| Riser alarm affecting more than one flat - Zone R1 or R2 | Confirm riser and affected flats from schedule | Operator follows authorised project riser isolation | Riser isolation fails or incoming-main action is considered | Affected riser flow stops | 24 hour line - EB-A-WS-02 |
