The supervisor must use the checklist together with the welder when planning and organising work in welding workshops. The checklist is also intended to support the manager in cooperation (between employers and employees) with the safety representative in the work of developing routines for safer work. The checklist is divided into five categories: 1) planning and organization, 2) goods reception and storage, 3) welding hall, 4) hazardous work steps and targeting, 5) slagging, grinding and alignment.
