Seismic monitoring uses sensors to measure ground vibrations produced by explosive demolition.

Shaped charges are explosive devices designed to focus the energy of an explosion in a specific direction or shape. Consisting of an explosive material arranged in a conical or hemispherical shape, typically with a metal liner or casing shaped to concentrate the explosive force, when shaped charges detonate, the explosive energy is directed inward toward a central point, creating a high-velocity jet of hot gases and molten metal. This jet can efficiently penetrate armour, concrete, or other materials. Shaped charges are used in military applications for anti-tank operations and in industrial settings for cutting or piercing thick materials. They can be tailored to specific targets or applications, requiring precise engineering and careful design to achieve the desired effect.

The standoff distance is the designated safe distance from an explosive device or hazardous area to minimise the risk of injury from detonation.
