Which of the following is a common safety hazard at construction sites?

The selection of all of the options reflects a comprehensive understanding of safety hazards commonly encountered at construction sites. Construction environments present a diverse range of hazards due to the nature of the work being performed, the materials used, and the equipment involved.

Slippery surfaces are a frequent concern, as various factors such as rain, mud, or spilled materials can create dangerous walking conditions, increasing the risk of slips and falls. This hazard necessitates proper materials management and the implementation of safety protocols to ensure safe movement across the site.

Exposed electrical wires pose a severe risk as they can lead to electric shock or electrocution if workers come into contact with them. Construction sites often involve temporary electrical setups or changes in existing wiring, which can leave wires unprotected if not properly addressed, making it crucial for workers to be aware of and avoid these hazards.

Falling objects represent another significant danger, especially in areas where materials are stacked or when tools are being used overhead. The risk of objects falling from heights can lead to severe injuries or fatalities, making proper safety measures like wearing hard hats and using barriers essential.

By acknowledging that all these hazards are prevalent at construction sites, the answer captures the multifaceted nature of risks that must be managed to maintain a safe working environment
