the interior of the vehicle or meet resistance. The third impact occurs when internal structures collide
within the body cavity.
What are the three factors that contribute to the damage caused by penetrating trauma's? -
ANSWER The point of impact, the velocity and speed of impact, and the proximity to the object.
What causes the primary effects of blast traumas? - ANSWER The direct blast effects. Types of
injuries include last long, tympanic membrane rupture and middle ear damage, abdominal
hemorrhage and perforation, global rupture, mild Trumatic brain injury.
What causes the secondary effects of blast traumas? - ANSWER Projectiles propelled by the
explosion. Injuries include penetrating or blunt injuries or I penetration.
What causes the tertiary effects of blast traumas? - ANSWER Results from individuals being
thrown by the blast wind. Injuries include hole or partial body translocation from being thrown against
a hard service: blunt or penetrating trauma's, fractures, traumatic amputations.
What causes quarternary effects of blast traumas? - ANSWER All explosion related injuries,
illnesses, or diseases not due to the first three mechanisms. Injuries include external and internal
burns, crush injuries, closed and open brain injuries, asthmatic or breathing problems from dust
smoke or toxic fumes, angina, or hyper glycemia and hypertension.
What causes quinary effects of blasts traumas? - ANSWER Those associated with exposure to
hazardous materials from radioactive, biologic, or chemical components of a blast. Injuries include a
variety of health effects depending on agent.
