Conclusions In summary, the findings showed the Dow Fire and Explosion Index is a suitable technique for measuring inconsistencies and it is also a criterion for measurement of the total hazards of a plant or of a part of the provided services. Estimation of potential losses caused by fire and explosion In the next step, the equipment values were estimated through replacement value in the contact area and damage factor DFwhich represents the sum of the damage of fire and ahzard and degradation of energy of the process clawsification.

Merely by properly improving the drainage system, this factor will reduce from 0.

Since a fire or explosion has not yet occurred in this industry, this information does not exist. Determination of Material Factor.

All authors contributed to this project and article equally. As a result, a series of changes and corrections was proposed such as modification of the drainage system, preparing the water supply for fire protection, establishing a sprinkler system, using water curtains, using the foam extinguisher, installing a leak detection system, establishing a cooling system, using cable protection devices, and implementing inert gas. Therefore, it is necessary to estimates the loss of working days or days out of service.

Then the radius of exposure and the area at risk were calculated. Considering the priority of reducing damage factors, several correction actions were suggested, such as modifying the drainage system, installation of hexane detectors, an automatic sprinkler system, fire detectors on the cable tray, and finally, using the water spray washing on the tanks.

Liquids or Gases in Process. It is apparent that by undertaking a series of corrective measures in the process unit, the amount of damages will be far less 9. Calculation of Fire and Explosion Index For this purpose, base and specific hazards of the process were monitored, then each hazard was assigned a new invoice. This obviously reduces the area at risk and consequently, will reduce the damage. Kumars Kian 3 B. Zeynab Sadat Nezamodini 1 M. Manufacturing Unit Risk Analysis Summary.

It also enhances resource management considering an optimal insurance contract. National Center for Biotechnology InformationU.

The extraction unit was, therefore, categorized as a severe risk and consequently, requiring correction measures. The losses estimated by this method can serve as a basis for determining the insurance costs of the explosion and fire. Material Factor Determination Guide.

This study was conducted in three distinct stages as follows: The Equipment Testing Procedures Committee is composed of engineers with substantial experience in the design and operation of process plants, as well as in solving problems that can arise with the equipment used in these guife.

Open in a separate window. Special Material Factor Considerations for Mixtures. Odw penalty factors, base hazard factor, and special hazard factor were calculated. This is a case study conducted in one of the process units of an oil extraction factory. Discussion The Fire and Explosion Index at the extraction unit was calculated as Methods This is a case study conducted in one of the process units of an oil extraction vlassification.

Introduction Fire and explosion accidents in process industries have incurred a large share of losses every year. Loss Control Credit Factors Form.

The results of calculating the DOW index showed that there were classificatiin and shortcomings in the existing control strategies. Please review our privacy policy. Consequently, the current study was performed to determine the expected losses more accurately and to encourage management to invest in control systems and to improve current fire and guuide control measures based on their priorities.

They include, lack of a fire sprinkler system, lack of water and foam curtains, lack of coating fire protection on the cable trays in the fire protection district, and a poor drainage system. Therefore, these days were calculated by following equations based on the most clqssification actual damages and considering the parameters that influence the cost of interruptions in production: Would you like to change to the site?

The most probable base damage classificationn is the damage without any safety and control measures in place was calculated by multiplying the value of the equipment and the damage factor. Data were obtained mainly through interviews and consultation with experts, as well as reported operating parameters and process documents.

Fire and Explosion Index Form. Hexane was the main hazardous material that was assigned, with the material factor MF 16 based on its properties.

Fire and explosion accidents in process industries have incurred a large share of losses every year. On the other hand, numerous deficiencies and pitfalls can be observed in fire protection systems in this company, which increases the loss control credit factor.

November 29,Quality control: Description This popular safety best-seller is designed to help the user quantify the expected damage of potential fire and explosion incidents in realistic terms, identify the equipment likely to contribute to the creation or escalation of an incident, and communicate the fire and explosion risk potential to management.

It was also used to calculate insurance rates for an optimal insurance contract. For example, a process unit equipped with a computer system with the ability to shut down the system if it receives critical data and to handle the system without the assistance of an operator, is a good risk reduction measure.

Process Unit Hazards Factors.

A series of corrections explosoon then proposed and risk analysis was performed again to examine the effects of reforms. The extraction unit was selected by taking into account several factors such as flammability and reactivity of materials, operating pressure, temperature, and the amount of material.

Added to Your Shopping Cart. Implementation of corrective measures in areas such as drainage systems, flammable liquid storage tanks, corrosion, erosion and leakage prevention can reduce the Fire and Explosion Index from Number 1 is allocated when there is not any control measure. There is no conflict of interest to be declared. In the next step, the equipment values were estimated through replacement value in the contact area and damage factor DFwhich represents the sum of the damage of fire and explosion and degradation of energy of the process unit.
