The study by Etowah et al.

Then temperature dow fire and explosion index hazard classification guide was carried out according to the thermal conditions of the study. The cause of high fire and explosion risk in this case study might be as a result guuide several risk factors, such as an improper drainage system, lack of neutral cclassification, corrosion and excessive wear, hexane toxicity, and working within flammability range. There is no conflict of interest to be declared. Assessment of safety and control measures It is essential to consider the series of existing protective and control measures, including those that might be inadequate, to more accurately estimate the amount of compensation in the event of fire and explosion.

Third, it is a user-friendly tool for evaluation of fire and explosion hazards in chemical process industries that uses available parameters such as temperature, pressure, and energy of chemical substances.

This is a case study conducted in one of the process units of an oil extraction factory. The results show that control process measures in this unit are more effective at reducing risk, than fire protection and material dow fire and explosion index hazard classification guide. It is apparent that by undertaking a series of corrective measures in the process unit, the amount of damages will be far less 9.

It is noted that a more realistic and accurate assessment of fire and explosion damage depends on the effectiveness of existing controls and safeguards.

It is essential to consider the series of existing protective and control measures, including those that might be inadequate, to more accurately estimate the amount of compensation in the event of fire and explosion.

Then the radius of exposure and the area at risk were calculated. Please review our privacy policy. For this purpose, base and specific hazards of the process were monitored, then each hazard was assigned a new invoice. Journal List Dow fire and explosion index hazard classification guide Physician v.

Suggested below are changes that should be and can classifiction be made exolosion take into account the ground realities. August 30,English editing: 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 insex likely to contribute to the creation or escalation of an incident, and communicate the fire and explosion risk potential to management.

This obviously reduces the area at risk and consequently, will reduce the damage. The credit factor is a number between 0 and 1. A series of corrections was then proposed and risk analysis classificatiln performed again to examine the effects of reforms. 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.

Therefore, these days were calculated by following equations based on the most probable actual damages and considering the parameters that influence the cost of interruptions classiffication production: This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs Licensewhich permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

This method was introduced by the Dow Chemical Company for fire and explosion hazard analysis.

classiication It might be more challenging to perform such a study in similar industries or in more complex industries where the amount of flammable materials is not accurately determined or where a large variety of material exists. The Dow Index of the processing unit was estimated to be There are three levels given in the Fire and Explosion index guide—upper, normal and lower.

Process sefety and invironmental protection.

Therefore, it increases the possibility of a large pool of hydrocarbon liquids forming around the process unit and consequently, the risk of fire and explosion 9.

In this study, the Dow Index is used for the following reasons: These accidents are, respectively, the first and second major risks in the process industries 1 that cause financial, human, and ecological losses.

Thus, dow fire and explosion index hazard classification guide closer the rate to 1, the fewer control measures for prevention and protection in place, and vice versa. The extraction unit was, therefore, categorized as a severe risk and consequently, requiring correction measures.

All authors read and approved the final manuscript. Functional significance of these findings is that, this criterion can provide guidelines for required changes or extend the protective equipment with respect to their effects in reducing the damage.

The penalty factors, base hazard factor, and special hazard factor were calculated. National Center for Biotechnology InformationU. In the next step, the equipment values were estimated through replacement value in the contact area and damage factor DFwhich represents the sum tuide the damage of fire and explosion and degradation of energy of the process unit.
