3132 Human factors briefing note no. 4 – Maintenance

Overview:

This document is freely available to all registered users of this site.

A task entailing the routine testing/checking, servicing or breakdown repair of plant or equipment. Failures in maintenance tasks can lead to injury to the fitter or to others, or to equipment malfunctions/system unavailability and to major accidents.

Why maintenance?

Maintenance work in major hazard industries could involve isolating process streams of dangerous substances, then stripping down and rebuilding a system - perhaps removing or disabling safety systems to do this - or, the task could be as simple as changing a fuse in a plug. Irrespective of the work undertaken, maintenance is a human activity and its quality depends upon the performance of the people who undertake it.
