Credit Structure:(3-0)3

Catalog Description :
Industrial hygiene and loss statistics, toxicology, source models (fluid flow through holes in tanks, pipes etc.), toxic release and dispersion models, fires and explosions, designs to prevent accidents, hazard identification and risk assessment, accident investigations with some sample case histories.

Course Objectives:
This course is designed to train senior undegraduate students on chemical process safety. The use of conventional chemical engineering principles such as fluid flow, thermodynamics, heat transfer, reaction analysis in designing safe chemical processes will be demonstrated.

Prerequisites :
None

Syllabus:
a.Introduction: Accident and loss statistics, public perception of chemical industry, the accident process, some significant disasters as case studies.
b.Toxicology: how toxicants enter and are eliminated from biological organisms, effects of toxicants, dose versus response models, threshold limit values.
c.Industrial hygene:government regulations, identification and evaluation and control of various exposures in chemicla industry
d.Source models: Liquid and/or vapor flow through holes in pipes in tanks, flashing liquids, liquid pool evaporation yand boiling.
e.Toxic release and dispersion models
