Connect electrical safety, battery hazards, cooling-system work, contractor activities, and corrective actions across continuously operating data centers.
Data centers depend on interconnected electrical, mechanical, and life-safety systems. Maintenance on switchgear, UPS equipment, generators, cooling infrastructure, or server installations can expose workers to hazards even when the facility continues operating normally.
Dexur EHS connects incidents, inspections, investigations, training records, and corrective actions across data halls, electrical rooms, battery installations, mechanical plants, rooftops, and generator yards.
Give EHS leaders, critical-facilities teams, engineering managers, and service providers visibility into the asset, work activity, system configuration, and protective measures behind each finding—from initial reporting through verified correction.
Request a Data Center EHS DemoFrom report to resolution
Data center work often takes place beside energized equipment and operating infrastructure. Redundant systems can support service continuity while introducing multiple power sources, automatic transfer functions, remote commands, and maintenance-bypass arrangements.
A work order may involve several teams: facilities operations prepares the system, a specialist contractor performs the task, security controls access, and another shift restores the equipment.
Safety teams need to understand the actual work configuration—not simply whether the asset is described as available or offline.
Dexur EHS connects the safety workflow:
Classify findings by the operating condition:
Record the facility, room, asset, system, contractor, and approved procedure reference.
For example, an isolation discrepancy during UPS maintenance may require review of the bypass arrangement, alternate sources, equipment labeling, and verification steps.
A coolant leak near a rack may require immediate access controls, electrical assessment, mechanical repair, and confirmation that the area is safe before work resumes.
Connect the finding to its responsible owner, interim measures, technical review, and verification evidence.
Capture worker injuries, electrical near misses, battery concerns, chemical exposures, equipment movement incidents, and unsafe work conditions.
Record whether the event occurred during routine rounds, planned maintenance, emergency repair, testing, installation, or commissioning.
Data center examples include:
Connect worker-safety consequences to any associated asset event while preserving separate operational-impact assessments.
Build inspections around the installed infrastructure and work performed.
Inspection topics can include:
Route technical findings to the responsible engineering or service team. Retain the verification needed before releasing a restriction.
Organize readiness records around the assigned task.
Relevant documentation includes:
Site access does not establish that a person is qualified to perform electrical work or service a particular battery system. Keep access approval, training evidence, and task authorization separately identifiable.
Manage actions arising from inspections, maintenance observations, incidents, audits, and commissioning findings.
Typical actions include:
Link a maintenance work order to the safety finding it addresses. Record whether the correction resolved the original exposure and whether any restrictions remain.
Use reporting categories that distinguish occupational hazards from service-availability events.
Incident and near-miss categories can include:
Record:
Avoid treating a system alarm as proof of worker exposure. Preserve the evidence needed to establish what happened and who was affected.
An electrical near miss may require review of source identification, drawings, labels, isolation, verification, and work-party communication.
A lifting injury may involve equipment weight, access clearance, rack stability, lifting aids, and staffing.
A chemical release may require examination of material compatibility, connection design, maintenance practices, and the immediate response.

Applicability follows the equipment, task, and work circumstances. NFPA standards used in a facility’s electrical or fire-safety program should be identified by the applicable edition and adoption or contractual basis, separately from OSHA citations.
A redundant power arrangement does not establish that a component is safe to work on.
Record the actual sources feeding the equipment, including UPS output, bypass paths, generators, and stored energy where relevant.
Under 29 CFR 1910.333, exposed live parts generally must be deenergized before work unless the employer demonstrates a specified basis for an exception. Operational preference alone does not establish that basis. Occupational Safety ...
Connect the safety assessment to the approved work procedure. Preserve electrical verification requirements alongside isolation records rather than treating a control-system indication as confirmation that equipment is deenergized. ecfr.gov
Identify whether the installation uses lead-acid batteries, lithium-ion batteries, or another storage technology.
Connect findings to the battery string, cabinet, module, or energy-storage installation involved.
Relevant observations include:
Lithium-ion systems can present thermal-runaway, fire, and hazardous-gas concerns. Preserve manufacturer guidance and the site’s approved response arrangements rather than applying one response method to every battery event. osha.gov
Keep routine UPS servicing distinct from specialized response to an abnormal battery condition.
Electrical, battery, cooling, fire-protection, and generator vendors may work on interconnected assets during the same maintenance window.
Record which equipment remains active, which employer controls isolation, and how work restrictions are communicated.
For covered activities under 1910.147, the host and outside employer must inform each other of their respective lockout/tagout procedures. Occupational Safety and Health Administration
Connect findings to the relevant method of procedure, work authorization, and shift handover. A completed change-management approval should remain distinguishable from worker-safety verification.
Cooling equipment can meet operational temperature targets while presenting maintenance hazards.
Track access to fans and pumps, retained pressure, refrigerant handling, treatment chemicals, and leaks affecting electrical or walking areas.
For liquid-cooled installations, record the coolant, connection, pressure state, and method used for component replacement.
Where cooling towers are present, connect water-management findings to responsible personnel and corrective work. CDC identifies an effective water-management program as the primary strategy for controlling Legionella growth and spread. CDC
Do not assign cooling-tower requirements to facilities without those systems.
Associate each generator with its fuel type, applicable regulatory classification, permit conditions, operating records, and maintenance requirements.
Distinguish emergency operation, testing, maintenance, and other use categories according to the applicable rules.
EPA’s data center guidance addresses stationary-engine requirements and air permitting. Applicable provisions can include 40 CFR Part 60 Subparts IIII or JJJJ and Part 63 Subpart ZZZZ, depending on the engine and circumstances. US EPA
Track fuel-transfer findings, leaks, and containment repairs alongside operational records. Avoid assigning one operating-hour allowance to every generator in the portfolio.
Maintain refrigerant records by appliance, refrigerant type, charge, service activity, and applicable requirement.
EPA Section 608 provisions govern relevant refrigerant-handling practices. Additional HFC leak-repair requirements under 40 CFR Part 84 apply to covered equipment; applicability should be evaluated separately rather than relying on a single generic refrigerant checklist. US EPA
For fire-protection work, track the affected area, impairment period, compensating measures, responsible contacts, and confirmation of restoration.
Keep refrigerant compliance, fire-system readiness, and equipment availability as distinct assessments connected to the same asset where appropriate.
Examples include:
Availability metrics do not show whether personnel are exposed during maintenance.
Connect safety findings to:
Consider severity, exposure frequency, system configuration, and the effectiveness of protective measures.
An electrical near miss, damaged battery installation, or incomplete isolation can require urgent attention even when no outage or injury occurs.

Dexur EHS supports investigation and follow-through. It does not replace electrical protection, building controls, approved switching procedures, or qualified engineering decisions.
Use injury outcomes and indicators showing whether high-risk work is prepared, controlled, and verified.
| KPI | What to measure | Data center application |
|---|---|---|
| OSHA TRIR and DART Rate | Recordable cases and days-away, restricted-work, or transfer cases normalized by hours worked. | Review employee and contractor outcomes with appropriate exposure data. |
| High-Potential Electrical Near Misses | Events with credible shock, arc-flash, or unexpected-energization potential. | Identify weaknesses in asset identification, isolation, and work practices. |
| Isolation and Verification Findings | Deficiencies discovered before, during, or after servicing. | Track electrical, mechanical, and stored-energy controls. |
| Battery Safety Findings | Damage, leakage, thermal concerns, and unresolved protective-system defects. | Compare findings by chemistry and installation type. |
| High-Risk Work Readiness | Assignments with required qualifications, procedures, and coordination completed. | Review electrical, battery, lifting, and elevated-work activities. |
| Critical Inspection Completion | Scheduled safety inspections completed on time. | Monitor electrical rooms, mechanical areas, generator yards, and access routes. |
| Contractor Safety Performance | Incidents, serious findings, and verified action closure by provider. | Evaluate specialist service work using task and hours-worked context. |
| Overdue Critical Impairments | Age and control status of unresolved safety-system impairments. | Follow fire protection, detection, barriers, and other protective functions. |
| Verified Corrective Action Closure | Actions completed on time with required evidence. | Confirm that repairs and procedure changes address the original exposure. |
| Repeat Findings After Closure | Recurrence involving the same asset, procedure, or work method. | Identify ineffective corrections and common fleet-level defects. |
Keep worker-safety indicators separate from uptime, power usage effectiveness, and equipment availability. Those measures describe different aspects of performance.
An increase in pre-work findings may indicate improved identification. Review the seriousness of the findings and the quality of follow-up.
Compare campuses while preserving differences in power architecture, battery chemistry, cooling design, and construction activity.
Review:
Monitor unresolved conditions affecting upcoming work:
Connect safety follow-up to maintenance planning while preserving separate approval responsibilities.
See the work restrictions, open findings, and actions relevant to the current shift.
Document changed conditions and carry unresolved matters into handover. Make temporary configurations and incomplete restoration checks visible to incoming personnel.
Review findings involving design, access, labeling, system boundaries, and maintainability.
Associate corrections with the installed configuration and supporting documents. Confirm that commissioning closeout includes unresolved worker-safety issues.
Follow assigned service findings, qualification requirements, refrigerant records, generator obligations, and impairment restoration.
Clarify who performs the work, who verifies it, and who authorizes the affected system’s release.
Drill into the work state, contractor, procedure, and equipment configuration associated with each record.
A data center finding often crosses operational boundaries. A technician identifies a labeling discrepancy, engineering evaluates the drawing, a contractor corrects the installation, and another shift prepares the equipment for service.
Dexur EHS preserves the relationship between the original concern and the decisions required to resolve it.
Record whether equipment was operating, isolated, bypassed, under test, or being restored. Preserve the configuration needed to understand the event.
Reference the relevant work order and procedure while retaining distinct investigation, verification, and approval requirements.
Assign actions to the electrical, cooling, battery, generator, or fire-protection team responsible. Make host-facility coordination visible.
Carry incomplete repairs, temporary barriers, and protective-system impairments into the next shift with clear ownership and review dates.
An asset can operate while an access, guarding, exposure, or documentation problem remains unresolved. Track those conditions independently.
Connect the completed repair or revised procedure to evidence that addresses the original hazard. Retain any remaining restrictions.
Identify recurring issues involving the same switchgear, UPS model, battery installation, cooling connection, or rack-handling method across multiple campuses.
Bring electrical near misses, battery findings, contractor inspections, environmental records, and corrective actions into one connected safety workflow.
