Introducing foreign objects in the equipment can cause a short-circuit, which can
result in irreparable damage, injury or death. Short-circuits release a large quantity
of energy, which leads to the quick expansion of superheated and ionized gases.
As a result, burns can occur even before preventive actions are taken. People and
objects can also be thrown several meters from the equipment.
Such foreign objects can be tools, test remains, instruments, wires, cables or
other objects, conductors or not. It is also advisable to maintains cloths and other
materials a long way from the equipment.
