13.3 EMESRT alignment
The Minetec SafeDetect system aligns with elements of the EMESRT Design Philosophy (DP-5) for
Machine Operation Controls and the Performance Requirement (PR-5A) for Vehicle Interaction
Systems as follows. The EMESRT performance requirements are discussed in EMESRT PR-5A
summary below. SafeDetect is based on 'cooperative' objects (equipment and personnel) equipped
with Minetec nodes and does not provide any active intervention control functions.
As such:
• SafeDetect does the following to prevent an unwanted vehicle interaction:
o Provides Level 7 Operator Awareness. o Provides
Level 8 Advisory Controls. o Applies only to the following
potential unwanted events:
 Equipment to Person.
 Equipment to Equipment.
• SafeDetect does not:
o Provide Level 9 – Intervention Controls. o Apply to
the following potential unwanted events:
 Equipment to Environment.
 Loss of Control potential unwanted events.
What is EMESRT?
The Earth Moving Equipment Safety Round Table (EMESRT) is a global initiative involving major
mining companies. EMESRT engages with key mining industry Original Equipment Manufacturers
(OEMs) to advance the design of the equipment to improve safe operability and maintainability
beyond Standards. For more information, see http://www.emesrt.org/about-us/
EMESRT PR-5A summary
The Vehicle Interaction Defensive Controls Model in PR-5A depicts nine defensive layers which
provide differing levels of process controls to prevent an unwanted vehicle interaction.
PR-5A specifically relates to the last three levels of defence for "systems to manage residual
interactive risk". These last three levels, grouped as the 'React' phase, are:
• Level 7 – Operator Awareness:
Technologies that provide information to enhance the operator ability to observe and understand
potential hazards in the vicinity of the equipment.
• Level 8 – Advisory Controls:
Technologies that provide alarms and/or instruction to enhance the operator ability to predict a
potential unsafe interaction and the corrective action required.
• Level 9 – Intervention Controls:
Technologies that automatically intervene and take some form of equipment control to prevent or
mitigate an unsafe interaction.
The above process controls apply to the potential unwanted event (PUE) scenarios of:
• PUE 1 Equipment to Person.
• PUE 2 Equipment to Equipment.
