ECONOMICS AND INSURANCE

Computation of Loss, Fire Insurance Claims, Legal provisions for Fire Loss, Economics of Loss Prevention, Cost of Losses, Cost of Prevention, Level of Loss Prevention Expenditure, Insurance of Process Plant, Damage Insurance, Business Interruption Insurance, Other Insurance Aspects.

Course Objective

To teach the significance of salvage and smoke movement in fire investigation process. To learn the fundamental of compartment fire and its application in fire investigation process. To calculate the fire loss by different methodology and application of data in identification of fire trends. To understand the evacuation process with different models of evacuation. To learn the role of insurance agency in legal and claim aspect.

Course Outcome

1. Students will able to demonstrate salvage equipments and apparatus with evaluation of smoke control parameter in occupancy. 2. Students will able to design compartment fire zone and formulate the fire dynamics of given problem. 3. Students will able to explain fire loss investigation process and prepare fire investigation report. 4. Students will able to prepare evacuation plan of a given occupancy. 5. Students will able to explain the role of insurance agency in fire loss.
