Introduction• Field servicing of surface mobile equipment represents a high risk
activity due to the interactions of equipment of different sizes with limited visibility and also with people
• As an organisation we have endured many significant incidents including a recent fatality involving field servicing of equipment
• This document is intended to present a recommended set up using hard barriers and procedures (including communication) for the different field servicing scenarios
• The scenarios covered are:– (1) Servicing equipment in a defined SME equipment park– (2) Servicing a single machine in a remote location– (3) Servicing multiple machines at a production location– (4) servicing a single machine in a remote location – no hard barriers
available – the situation we must work towards eliminating
