Elements and Performance Criteria

1. Confirm the requirements for Phase II mushroom substrate preparation
   • Monitor and manage Phase II mushroom substrate process and ensure that all equipment is operated safely
   • Check to ensure all temperature probes are functioning correctly
   • Ensure site quarantine protocols and farm and personal hygiene requirements are followed
   • Assess condition and quality of compost before filling
2. Carry out Phase II process
   • Monitor placement of probes in air and substrate
   • Check the evenness of filling and the amount filled
   • Ensure doors are secure and vents and thermostats are set at completion of filling
   • Measure and record key factors and critical points
   • Adjust equipment settings to ensure optimum conditions for each Phase II sub-stage
   • Take random representative samples for laboratory testing
   • Determine ammonia levels before cool down for spawning

Range Statement
