Range Safety Exam; Questions and Answers
100% Pass
Surface Danger Zone (SDZ) Correct Answer-The ground and air space designated within the
training complex for vertical and lateral containment of projectiles, fragments, debris, and
components resulting from the firing, launching, or detonation of weapon systems to include
explosives and demolitions.
Dispersion Area Correct Answer-The area within the SDZ located between the GTL and the
ricochet area. This area accounts for human error, gun or cannon tube wear, propellant
temperature, and so forth.
Angle P Correct Answer-The angle beginning at the firing point, located to the left and
right of the dispersion area, which defines the area which contains projectiles after making
initial contact with the target medium.
Angle Q Correct Answer-The angle beginning at distance Y, located to the left and right of
the dispersion area, which defines the area which contains projectiles after making initial
contact with the impact medium.
Area A Correct Answer-The secondary danger area that laterally parallels the impact area
or ricochet area and contains fragments, debris, and components from frangible or explosive

projectiles and warheads functioning on the right or left edge of the impact area or ricochet
area.
Area B Correct Answer-The secondary danger area on the downrange side of the impact
area and Area A which contains fragments, debris, and components from frangible or
exploding projectiles and warheads functioning on the far edge of the impact area and Area
A.
Gun Target Line Correct Answer-An imaginary line drawn between the firing position and
target position. Also referred to as the line of fire.
Firing Position Correct Answer-The point or location at which a weapon system is placed
for firing. For demolitions, the firing position is the point or location at which the firing crew is
located during demolition operations.
Distance X Correct Answer-The maximum distance a projectile will travel when fired or
launched at a given quadrant elevation with a given charge or propulsion system.
