EOP Example — Water Leak Response

Document ID: EOP-WTR-003

Revision: 1.0

Status: Example

Activation: Water Leak / Water Detection

1. Purpose

Provide a structured response framework for water leak or water detection incidents affecting critical infrastructure operations, with focus on personnel safety, leak containment, infrastructure protection, operational overview, escalation and incident control.

2. Scope

Applies to abnormal conditions involving water leaks, condensate leaks, pipe failures, cooling-water incidents, roof ingress, drainage overflow or water detection alarms affecting technical rooms, data halls or supporting infrastructure spaces.

This example does not replace plumbing repair procedures, electrical safety procedures, fire procedures, manufacturer instructions, local regulations or site-specific emergency plans.

3. Activation Criteria

This EOP may be activated when one or more of the following conditions are observed:

Visible water leak in a technical or operational area
Water detection alarm activation
Condensation or moisture affecting critical infrastructure
Pipe, valve or hose failure
Cooling-water leak affecting operational rooms
Roof ingress or external water intrusion
Drain blockage or overflow condition
Water located near energized equipment or critical systems

Emergency principle: Protect personnel first, then stop spread, then stabilize infrastructure impact.

4. Immediate Response Priorities

Priority	Focus Area	Objective
1	Life Safety	Identify electrical, slip or structural hazards.
2	Leak Identification	Determine source, location and active spread.
3	Containment	Limit water spread and protect critical infrastructure.
4	Operational Overview	Determine affected systems and current operational risk.
5	Communication	Notify responsible stakeholders and escalation paths.
6	Incident Logging	Maintain timeline and operational record.

5. Initial Response Procedure

Step	Area/Tag	Action	Verification	Owner
1	OPS-BRIDGE	Declare operational incident and assign response lead.	Single responsible coordinator established.	Operations Lead
2	AFFECTED AREA	Confirm personnel safety and identify immediate hazards.	No uncontrolled electrical or personnel hazard remains.	Operations / Security
3	WATER-DETECTION / ROOM	Identify visible leak source, leak path and affected area.	Leak location and spread direction understood.	Facility Operations
4	CRITICAL INFRASTRUCTURE	Determine whether water threatens energized equipment or critical systems.	Current infrastructure risk level identified.	Electrical Responsible Person
5	CONTAINMENT	Deploy approved containment measures if safe and available.	Water spread reduced or controlled where possible.	Facility Operations
6	BMS / DCIM	Review alarms and affected environmental or cooling systems.	Secondary infrastructure impact identified.	Operations
7	COMMUNICATION	Notify required stakeholders according to incident communication plan.	Stakeholder notification completed and logged.	Incident Lead
8	INCIDENT LOG	Start or maintain incident timeline and operational log.	Observations, actions and escalation decisions continuously recorded.	Assigned Recorder
9	OPS-BRIDGE	Establish monitoring interval and escalation threshold.	Response cadence agreed and communicated.	Incident Lead

6. Containment and Stabilization

Containment actions should focus on limiting infrastructure exposure while maintaining personnel safety and operational control.

Protect energized equipment from direct water exposure
Prevent water migration into additional technical areas
Protect floor openings, cable penetrations and airflow paths
Use only approved containment materials and methods
Maintain safe access and evacuation routes
Escalate immediately if leak source cannot be identified

Any isolation of water systems, cooling systems or electrical systems should follow approved site procedures and authorized decision-making.

Control rule: Avoid uncontrolled intervention near energized equipment. Escalate uncertainty early.

7. Escalation Triggers

Immediate escalation is required if one or more of the following conditions occur:

Water reaches energized equipment or power infrastructure
Leak source cannot be identified or controlled
Cooling infrastructure becomes affected
Water spreads into critical technical areas
Structural damage or ceiling instability is suspected
Environmental monitoring becomes unavailable
Additional leaks or alarm points appear
Personnel safety becomes uncertain

8. Communication Structure

Water incidents should be communicated using clear factual updates focused on:

Current leak status
Affected areas
Infrastructure risk level
Containment progress
Escalation actions
Expected next update

Example update structure:

Time → Leak Location → Current Spread → Infrastructure Impact → Containment Status → Risk Level → Next Update

9. Recovery and Return to Normal

Recovery should focus on restoring a known safe and stable operating condition before closing the incident.

Verify leak source isolated or repaired
Verify no remaining active water spread
Inspect affected infrastructure for residual risk
Confirm cooling, power and monitoring systems stable
Review environmental alarms and moisture conditions
Remove temporary containment only after approval
Complete incident documentation and operational review

11. Operational Notes

Water incidents in technical facilities are often deceptive. Small leaks can migrate through cable routes, floor penetrations, ceilings, containment systems and hidden infrastructure paths before becoming fully visible.

Strong response depends on maintaining overview, escalating early and preventing secondary infrastructure impact while avoiding unsafe improvisation.

Real emergency response procedures must align with facility design, electrical safety requirements, environmental controls, local regulations and approved operational governance.
