Risks associated with process facilities, pipelines, and accident records around the world indicate that in addition to the need of using up-to-date design standards, safety precautions need to be taken to protect human and financial capital. Determining the area around facilities and pipelines with hazardous materials must be done carefully because if the safety area is chosen to be unnecessarily large, it will impose high costs and create problems for residents. Furthermore, determining the area regardless of the dangers of the complexes will cause some risks to the surrounding population. AITCE is proud of reviewing the safety complex of IGAT high pressure gas pipelines of the country, as the first safety engineering consultant. These services have also been provided to other sectors of the oil, gas and petrochemical industry, including the facilities of the Oil and Petrochemical Company.
