Different time frames in the implementation and maintenance of barriers

3 Different time frames in the implementation and maintenance of barriers 

Active barriers are to a large extent dependent on activities in the day-to-day operation. Many of them are established and maintained through the different activities to allocate resources and to control production, including the allocation and supervision of personnel, control of work material and technical systems, co-ordination of activities and housekeeping. The individual operators play a significant role in the immediate control of accident risks by detecting and avoiding hazards. In case of major accident risks, the technical control systems will usually take over from the operators, if they fail to keep the production process within accepted limits. 

At the next level, the barriers are implemented and maintained through long-term measures related to design and organisation of the workplaces and measures directed at the work group and the individual operator. Table 7.1.
