Isolation Design - Can you help prevent exposure to fatal energies?
How can South32 better design and secure their isolations to guarantee their workers remain free from harm?
Currently, one of the critical controls preventing the workforce from being exposed to potentially fatal energies (electrical, chemical, mechanical) is the manual isolation and “locking” of isolations points (valves, electrical isolators).
A relative industry standard process is then utilised to secure the isolators using a series of Padlocks.
The isolation process sees an operator reviewing the Scope of Work and designing the isolation by following equipment and lines in the field or relying on previous examples of isolations which may or may not have been effective.
Errors can occur when the design of the isolation does not include all energy sources, or the isolation is put on the incorrect isolation point in the field.
To help us achieve our goal of being able to guarantee that people working with energies remain safe, how do we design and secure our isolations using our blueprint and historical data to eliminate the possibility of failure?
Potential Areas to consider
• How can the system design an isolation from scratch?
• Is there a better way of ensuring the isolation is secured than locks?
• What other ideas do you have to improve the process?
Data will include a data dictionary and introductory video
- Clearance to Work Procedures
- Clearance to Work Critical Controls
- Historical scopes of work (work orders), associated isolations and permits to work from our Isolation Database (Intellipermit) and work management system (SAP)
- Lists of Isolations types and examples
- Piping and Instrumentation documents
