 Abstract

This study proposed a fuzzy-based HAZOP for process risk analysis. Fuzzy theory was used to express uncertain states and this theory has been found to be a useful approach to overcome the inherent uncertainty in HAZOP analyses. Fuzzy logic contrasted sharply with classical logic and provided different risk values according to the degree of its membership functions. The appropriate process parameters and guidelines were selected to describe accident frequency and consequences. Fuzzy modelling calculated risks based on the relationship between accident variables. Modelling was based on mean expected value, trapezoidal fuzzy number method. The objective process for fuzzy-based and conventional HAZOPs was to identify and assess hazards in boiler plant. The most important index is the frequency of risk determination. The comparison results showed that the fuzzy-based HAZOP provides better elaborated risks than the conventional HAZOP. The fuzzy risk matrix represents the importance of risks, negligible risks and the need to reduce risks.

 Abstract

The fastest approach to reduce fire risk and losses is to prevent fires. Investments in prevention are occasionally significant. Active systems, such as fire sprinklers and alarms, portable fire extinguishers, and facility inspections, react to the presence or threat of fire with conditioned responses, and passive systems, such as sufficient occupant evacuation egress, fire-resistant construction, and flammable liquid storage cabinets, mitigate threats constantly to be able to prevent or reduce fire losses. Security systems, both passive and active, require routine upkeep and inspection. An illustration of a manual fire prevention and protection measure is a fire extinguisher.Other options include automated fire sprinklers, suppression systems, and separation barriers. Regular supervision, training, and inspections are necessary for manual activities.Inspection and maintenance are necessary for automatic systems. Passive barriers (like fire doors) may be compromised by renovations and occupant behavior. Facilities managers need to be familiar with all forms of fire prevention and protection, maintain them, and encourage deployment where it makes sense from a risk management standpoint. The FM200 system is a cross-zoned, double-knock system. Two detectors on it need to sound an alarm before the releasing sequence can begin. Only if one detection results in an alarm will the FM200 system enter pre-alarm mode. The FM200 is an independent system. Fire detection, trustworthy monitoring, and interaction with mass notification systems are all possible features of integrated fire alarm systems. Since features and capabilities differ from one fire alarm system integration to another, the term integration might be ambiguous. This is done to protect human life during industrial catastrophes.
