  • Guidance note for environmental safety instrumented systems

    Safety Instrumented Systems (SIS) are designed to monitor the process and control outputs to prevent or mitigate hazardous events. The design process strives for inherent safety, which is enhanced by applying multiple independent safety layers. Learn how to prevent accidents with prevention layers and minimise the consequences with mitigation layers.

  • Managing Complex Equipment Status in a GMP Environment

    Batch manufacturing systems must maintain the status of equipment, including which are available, dirty, out of service, etc. In industries that enforce Good Manufacturing Practices (GMPs), additional status types and values for process equipment must be maintained. Rules associated with the equipment status can be complex and involve the equipment class, current equipment state and time in the current state. This paper covers the operator interface used to review the equipment status and the interlocking requirements between the recipe and batch phases based on multiple status types.
