Data Centre Maintenance Safety: Ensuring Safe Operations with Real-Time Monitoring

The bank planned to carry out Electrical Testing Inspection (ETI), a vital part of ongoing data centre maintenance. This process required powering down sections of the facility, so the work had to be carefully scheduled to avoid impacting live banking services.

Two key challenges threatened progress:

Strict COVID-19 protocols forced the team to rethink how maintenance activities were coordinated. Engineers had to work in smaller teams, follow staggered shifts, and maintain safe distances across the data hall.

Technicians were understandably concerned about working in an enclosed space with limited visibility into air quality. Without clear data on environmental conditions, the bank struggled to guarantee data centre maintenance safety and reassure its workforce.

To address these challenges, the bank partnered with Advanced Datacentre Systems (ADS) to deploy a real-time monitoring solution focused on improving data centre maintenance safety.

At the heart of the deployment was the iSensor Controller, a compact and scalable platform capable of supporting multiple sensors across the data centre environment.

ADS implemented intelligent CO² Sensor units throughout the data hall. These sensors continuously monitored:

• Carbon dioxide (CO²) levels
• Temperature
• Humidity
• Infection Risk

This enabled the team to maintain a real-time understanding of environmental conditions during maintenance activities.

To go beyond standard monitoring, the solution incorporated the Wells-Riley model.

By analysing air quality data, the system calculated the probability of airborne infection transmission in real time. This allowed the bank to:

• Assess risk levels before and during maintenance work
• Identify areas requiring improved ventilation
• Make informed decisions to protect on-site personnel

Sensors were strategically positioned across each row to ensure full coverage and accurate insights throughout the facility.

With real-time environmental data available, engineers gained the confidence to safely carry out maintenance tasks. The system provided:

• Live visibility into air quality and environmental conditions
• Clear indicators of infection risk levels
• Data-backed reassurance for safe working practices

The solution continuously monitored predefined thresholds and triggered instant alerts when conditions changed. This enabled teams to respond quickly and maintain safe environments throughout maintenance activities.

By adopting a data-driven approach to data centre maintenance safety, the bank successfully:

• Completed ETI testing on schedule
• Maintained uninterrupted banking operations
• Protected the health and safety of all personnel

• Enhanced data centre maintenance safety through real-time monitoring
• Continuous tracking of air quality, temperature, and humidity
• Infection risk modelling using the Wells-Riley equation
• Increased engineer confidence and workforce safety
• Zero disruption to critical operations.

This project highlights a broader shift in how organisations approach data centre maintenance.

Safety is no longer limited to physical procedures alone. Modern facilities now rely on real-time data to:

• Reduce risk during maintenance activities
• Protect both personnel and critical infrastructure
• Maintain uptime while carrying out essential work
• Support compliance and operational best practices

By integrating environmental intelligence into maintenance strategies, organisations can move from reactive safety measures to proactive risk management.
