dear nouses
the idea of muhlbauer model, is qualitative risk assessment. that's why i don't need to measure exactly consequence as it refered as LIF in muhlbauer model. then, consequence factor value represent by leak impact factor shall be able to scale qualitatively the consequence of pipeline failure. By this meaning, you can scale gas to liquid, large diameter to small diameter, high consequence area to rural or remote zone, and other area receptance value (environmental, business, agriculture, etc). To do this, you can refer to some approach in Muhlbauer book.

Hope this answer your question.
