The loss prevention philosophy implemented in a hydrocarbon facility for the safe operation of the facility either during manned operations or unmanned operations depends on parameters such as the design strategy adopted while designing the facility (such as facility layout, fire protection, flaring design, drains design), areas classifications inside the facility that is designed, escape and evacuation route, climate control etc.
Hazardous events usually occur either as the result of a combination of unusual circumstances, occurring simultaneously or by allowing the escalation of a series of minor events, none of which is, by itself, a major hazard. Therefore, the installation is designed robustly to detect conditions that could lead to hazardous situations, and to rapidly, automatically apply, or allow the application of, corrective measures. Similarly, consideration is given to the design of escape facilities to prevent their obstruction or impairment by hazardous events.
