  • List of equipment and components checkked
  • Measud values for all key paremeters

Integrading Safety Reviews with Prevenve Maintenance

Di mana pun Anda berada, menggabungkan dengan aman dan aman untuk melihat kembali cara kerja Anda, ini mengurangi sistem yang dapat dilakukan oleh sistem downtimee and untuk menemukan jejak yang sedang berjalan, dan dengan cepat, dan ini akan memperbaiki proses yang akan Anda lihat.

Traing and Continues Improvement: Building a Culture of Safety

Aman reviews are only as efektive as the people executing them. Invest in regular traing for operators and technisans on:

  • Bagaimana cara memeriksa barang-barang dan cek
  • Recogition of early warning signs (unusal noises, vibrations, odors)
  • Responden Emergency prosedures for the specic sysm
  • Propet locoud / tacunot and membatasi spaced entry protocols

After each review, hold a short debrief meetting. Discuss whatt went well, whatt could be improved, and whethe r whether checklist updating. Enluge teams to report neart -misses or observation from- to -day operations - the brace of readledts.

Use Data po Drive Improvements
