In a Hospital Pathology department, extraction fans are life-critical infrastructure. They manage hazardous chemicals that require 24/7 ventilation. When long-term weather exposure caused the unit isolators to fail inspection, GBB Electrical Ltd was called in for an urgent, high-stakes upgrade.
The Challenge
The department handles special cases and must remain fully operational at all times. We faced a dual challenge: we could not switch off the power due to other critical medical equipment in the building and the existing circuits were completely unlabelled. This required meticulous tracing and validation in a live, high-pressure environment.
The Solution
Our engineers successfully validated and upgraded the weathered isolators with zero interruption to hospital operations. By carefully mapping the circuitry while live, we ensured the extraction systems were restored to full compliance without a single second of downtime for the department.
