Abstract

Storing relatively large amounts of hazardous materials under certain conditions can lead to high-risk situations. In industrial units, the assessment of the amplitude and severity of the consequences of the identified major accidents is done in order to provide data on site intervention and emergency planning. This study aims to assess the consequences of untimely releases of hazardous explosive / toxic substances in an industrial unit by graphical modelling and analysis of such accident scenarios using specialized software tools. The main activity of the industrial unit under study consists in the manufacture, processing and marketing of essential oils and their derived products.

Highlights

  • 4.3.1 Scenario 1 - The leakage of the entire quantity of substance (500 kg) from a tank located in the area of the production hall

  • Following the modelling of the 2 possible accident scenarios, the following conclusions can be drawn: For Scenario 1 – leakage of the entire quantity of substance (500 kg) from a tank located in the area of the production hall

  • The identified vulnerable point located in the area of attention is the residential area 32 (580 m) – Figure 11

Summary

Introduction

The purpose of the major risk prevention policy and the purpose of the safety management system is to implement within the industrial units the legal provisions to prevent major accidents, and in case of a major accident, to succeed, through the actions taken, to minimize the impact and amplitude. Given the legal provisions in force on the control of major accident hazards involving dangerous substances industrial units have to adopt policies to prevent major accidents involving dangerous substances and must have appointed a responsible for security management. The policy for the prevention of major accidents involving dangerous substances on site is drawn up in order to achieve, in a short time, in an organized and unitary way, the measures of protection, intervention and reduction of the effects resulting from a major accident involving dangerous substances. The assessment of the amplitude and severity of the consequences of the major accidents identified is made in order to provide data on site intervention and emergency planning [1]
