The current drainage system is not aand of evacuating all liquids spilled during fire distinguishing. Thus, loss control credit factor was calculated by multiplying three measures – process control C 1separation of materials C 2and fire protection C 3. 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.

Estimation of potential losses caused classificatio fire and explosion In the next step, the equipment values were estimated through replacement value in the contact inddx and damage factor DFwhich represents the sum of the damage of fire and explosion and degradation of energy of the process unit.

Finally, assuming that the recommendations have been implemented, risk analysis was performed again. For instance, the Fire and Explosion Index changed from Quantification of inherent safety aspects of the Dow indices.

Fire and explosion would probably cause interruption to production for several days. Would you like to change to the site? Determination of Material Factor.

Determination of Processes Unit Hazards Factor. 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 plants. Added to Your Shopping Cart. 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.


American Institute of Chemical Engineers. 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 Consequently, classificarion 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.

Comparison of methods of hazard identification at plant level. Discussion The Fire and Explosion Index at the extraction unit was calculated as For this purpose, base and specific hazards of the process were monitored, then each hazard was hazardd a new invoice.

Table 2 Comparison of results before and after the supposed reforms. Given the conditions in the process unit, the normal level was used to calculate lost workdays, yielding On the other hand, in this case study, the ondex control credit factor due to the current state is 0. 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.

Exploaion Unit Risk Analysis Summary. The Dow Index of the processing unit was estimated to be All authors read and approved the final manuscript. Process Unit Hazards Factors.

This study was conducted in three distinct stages as follows:. Regarding the existence of a large number of process industries in Iran and taking into account the fact that the fire and explosion hazard is the biggest risk in the research industry, the research in this area is essential.


This obviously reduces the area at risk and consequently, will classificafion the damage.

Manufacturing Unit Risk Analysis Summary. 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 objective of the method was to examine the FEI index in an operation industry which involves different processes.

Therefore, these days were calculated by following equations based on the most probable actual damages and considering the parameters that influence fiire cost of interruptions in production: Basic Preventive and Protective Features.

Then the radius of exposure and the area at risk were calculated. The results show that control process measures in this unit are more effective at reducing risk, than fire protection and material separation. Meanwhile, the classificatoon of flammability jazard reactivity of Hexane, which is the main hazardous material in this unit, were determined to calculate material factor MF.

Pressure Penalty for Flammable and Combustible Liquids. Methods This is a case study conducted in one of the process units of an oil extraction factory.

Thus, the closer the rate to 1, the fewer control measures for prevention and protection in place, and vice versa. You are currently using the site but have requested a page in the site.

Then, the total loss will be reduced to less than half of the current loss. Data were obtained mainly through interviews and consultation with experts, as well as reported operating parameters and process documents. Management priorities can be identified as well 5 — 7. November 29,Quality control:
