Fume Extract system refurbishment at Etches Park rail maintenance depot
The importance of accessibility for maintenance is not to be overlooked in the installation of fume extract, smoke control and fire safety systems.
Poor planning during the initial stages of design may lead to an inaccessible system and subsequently, the inability to undertake the proper maintenance and servicing. Without regular maintenance a system can, over time, deteriorate to the point of failure – rendering itself ineffective in extracting noxious fumes and smoke in the event of a fire.
This was precisely the issue at the Etches Park rail workshop where Airvent was appointed to replace a number of roof mounted fume extract fans that had become inoperable through lack of maintenance.
An initial exploratory investigation was undertaken by Airvent to ascertain the condition of the fans. The result of the investigation concluded that the only way to access the fans was via a team of specialist abseil-engineers, supported by an internal access platform.
Engineers replaced each of the 33 existing fans and introduced a sling to each – allowing the motors to be ‘underslung’ so future maintenance can be achieved internally.
With Health & Safety of their employees being a top priority for the client, Airvent also installed 24 carbon monoxide, carbon dioxide and nitrogen oxide detectors to ensure that a clean and comfortable working environment will be maintained at all times. The detectors were linked to the main control panel while the MCP was modified for the re-zoning of the fans.
Airvent has since been appointed to provide ongoing maintenance for this system.
“Our pre-emptive planning strategy allowed us to anticipate future maintenance work and devise a solution to ensure there were no further access restrictions that would prevent it.”
