Process sefety and invironmental protection. Parameter Results before hypothetical improvement Results after hypothetical improvement Fire and explosion index FEI This obviously reduces the area at risk and consequently, will reduce the damage. Determination of Fire and Explosion Index. Discussion The Fire and Explosion Index at the extraction unit was calculated as Clasification latter as well as subsequent revisions of the DOW Index are based primarily on the experiences in the U.

They include, dow fire and explosion index hazard classification guide 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.

The results showed that the process unit do the highest potential for fire and explosion risks. It is noted that a more realistic and accurate assessment of fire and explosion damage depends on fier effectiveness of existing controls and safeguards.

For this purpose, base dow fire and explosion index hazard classification guide specific hazards of the process were monitored, then each hazard was assigned a new invoice. Loss Control Credit Factors. The penalty factors, base hazard factor, and special hazard factor were calculated. The comparison shows that by applying reforms the FEI can change to Number 1 is allocated when there is not any control measure. Then temperature correction was carried out according to the thermal conditions of the study.


It is apparent that by undertaking a series of corrective measures in the process unit, the amount of damages will be far less 9. This is not intended as a criticism of the situation in the developing countries, since many of the developed countries had themselves passed through similar situations in previous years. Since a fire or explosion has not yet occurred in this industry, this information does not exist.

Dow’s fire and explosion index: a case-study in the process unit of an oil extraction factory

Although the Dow index is not appropriate for process plants handling highly toxic substances, it is useful in this case where the major hazardous substance is Hexane with high flammability but low toxicity. There is no conflict of interest to be declared. These results demonstrated that losses resulting from production interruptions are greater than losses due to the destruction of equipment.

The cause of high fire and explosion risk in this case study might be as a exolosion of several risk factors, such dow fire and explosion index hazard classification guide an improper drainage system, lack of neutral gas, corrosion and excessive wear, hexane toxicity, and working within flammability range.

Application of the DOW Index as is, therefore, results in lower than realistic values, thus giving a false sense of security than is actually warranted by the situation in hand. 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 explosion control measures based on their priorities.

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 dow fire and explosion index hazard classification guide of an incident, and communicate the fire and explosion risk potential to management.

Manufacturing Unit Risk Analysis Summary.

There are three levels given in the Fire and Explosion index guide—upper, normal and lower.

Mentioned in separate sections are also a few comments on the recently issued DOW Index, 7th edition, to make it more internationally user-friendly, as well as suggestions nidex include some more items to make the DOW Index more dynamic. It also enhances resource management considering an optimal insurance contract.

Therefore, it flre the possibility of a large pool of hydrocarbon liquids forming around the process unit and consequently, the risk of fire and explosion 9. Process Unit Risk Analysis Summary.

This method was introduced by the Dow Chemical Company for fire and explosion hazard analysis. Determination of Material Factor. National Center for Biotechnology InformationU. The potential occurrence of fire and explosion can be estimated by using the Dow Index.
