104 ◾ Risk Assessment and Security
on the event or on the surrounding condition. Hence, in the rst rupture of a
freight capsule containing HAZMAT or ammable uid, the overpressure may
happen due to minimal or high rate of pressures, while the explosion increases the
rate of pressure. Blasting of the freight capsule increases shock waves, while gas
pressure, ambient pressure, dynamic pressure, and wind exert forces resulting in
acceleration of the missiles.
3.2.7.4 Angle of Departure of Missiles
e ight of a missile can be estimated and the angle of departure is required in the
process. Moreover, the angle of departure of missiles from a blasting mass transit
due to terrorist attacks can be modeled and calculated so that preventive measure ...
