What must be ensured regarding utilities before demolition begins?

Before beginning any demolition work, it is crucial to ensure that all utilities, such as gas, water, electricity, and sewer lines, are disconnected. This safety measure is essential to prevent accidents such as explosions, fires, or electrocution, which could occur if these services are inadvertently damaged or activated during the demolition process. Disconnecting utilities helps create a safe working environment for the demolition crew and helps mitigate potential hazards associated with exposed or live utility lines.

Maintaining connected utilities during demolition could lead to severe risks, including injury to workers or passersby, damage to surrounding properties, and environmental hazards. Therefore, proper planning and coordination with utility companies to safely disconnect services before commencing any demolition work is a fundamental requirement of safety regulations and best practices in the field.
