Intersystem Interaction and Relationships in the Integrated Safety System Designed to Prevent Accidents and Fires at Explosion- and Fire-Hazardous Enterprises

The statistics of accidents and fires at explosion- and fire-hazardous enterprises have been analyzed. It implies that about 20 % of the total number of hazardous events (accidents and fires) occur at such enterprises annually and the caused damage comprises approximately 46 % of the total damage caused by accidents. These hazardous events lead to sanitary and irreversible loss of personnel and third persons. The rationale for establishing the integrated safety system considered «a system in the system», whose activity aims at the prevention of hazardous events (accidents and fires), has been provided. An escalation chain of events causing accidents and fires at explosion- and fire-hazardous enterprises has been shown in the functioning process of autonomous safety fields (fire and industrial safety, occupational safety) that provide control over production activities of personnel of the enterprise’s structural departments. Theoretical substantiation that establishes the fact of the importance of the index of negative or low-quality impact of safety fields (fire and industrial safety, occupational safety) within the integrated safety system represented as «a system in the system» when determining the damage risk level caused by accidents and fires is provided. An example illustrating scenarios of defects (errors) for one of the fields (fire and industrial safety, occupational safety) confirming the facts of damage to other interacting fields has been demonstrated. The necessity to establish an integrated safety system capable of determining causes of hazardous events (accidents and fires) for top-level managers at explosion- and fire-hazardous enterprises is confirmed.
