JNTUK B.Tech Industrial Safety & Hazard Management gives you detail information of Industrial Safety & Hazard Management R13 syllabus It will be help full to understand you complete curriculum of the year.
Learning Objectives
- To educate in HSE in handling and storage of hazardous chemicals and in safe operation of unit operations/ unit processes like reactions, distillations, compression/expansion, and absorption/desorption etc.
- To learn the principles of designing equipment eliminating the possibilities of fire, explosion, toxic releases etc.
- To learn how to overcome hazardous situations during installation, pre-commissioning, commissioning, normal operation and/or during execution of any maintenance work.
- To learn various techniques and measures available to investigate industrial accident.
UNIT-I: Introduction: Safety programs – Engineering ethics – Accident and loss statistics – Acceptable risk – Public perceptions – The nature of the accident process – Inherent safety.
Toxicology: How toxicants enter biological organisms – How toxicants are eliminated from biological organisms – Effects of toxicants on biological organisms – Toxicological studies – Dose Vs response – Models for dose and response curves – Relative toxicity – Threshold limit values.
UNIT-II: Industrial hygiene: Government of India regulations and OSHA – Industrial hygiene identification – Evaluation – Control.
Source models: Introduction to source models – Flow of liquid through a hole – Flow of liquid through a hole in a tank – Flow of liquids through pipes – Flow of vapor through holes – Flow of gases through pipes – Flashing liquids – Liquid pool evaporation or boiling – Realistic and worst- Case releases.
UNIT-III: Toxic release and dispersion models: Parameters affecting dispersion – Neutrally buoyant dispersion models – Pasqual-Gifford model – Dense gas dispersion-Case Study.

Outcomes: After the course, the students will become knowledgeable in the following:
- Accessing the various hazards involved in handling hydrocarbons in Oil & Gas sector. Visualization of all possible safety issues at all the phases of industry by applying the techniques like Hazop, QRA etc.
- Steps to be followed during design stages to overcome possible safety threats.
- Measurement and monitoring of safety index.
- Fire preventing/Firefighting systems.
- Accident investigation process-Root causes analysis.
