What is meant by "Containment" in electrical installations?

Containment in electrical installations refers to the practice of creating compartments within a building using fire-resistive walls. This is essential for limiting the spread of fire and smoke, thereby protecting both the electrical installations and the overall structure. By constructing fire-rated barriers, the potential for fire to travel through conduits or electrical pathways is minimized, helping to enhance safety and ensure compliance with building codes and fire safety regulations. This method of containment is crucial for maintaining the integrity of both the electrical system and the building itself in the event of a fire, thereby improving safety for occupants and safeguarding property.
