NORTH MIAMI BEACH, FLA. (WSVN) - Two men were injured in a chain reaction construction site accident in North Miami Beach.

North Miami Beach Police and Miami-Dade Fire Rescue units responded to a building under construction in the 16300 block of Biscayne Boulevard on Monday morning.

“Be advised it’s going to be a trauma alert. We have one adult male patient that fell from the ninth story,” said a dispatcher.

According to Ralph Rayburn in 7Skyforce, who hovered above the scene, a construction lift malfunctioned and plummeted from the ninth floor of a residential building under construction.

“They were up at the ninth floor and the motor on the lift blew up and they fell nine stories down,” said Rayburn.

A motor powering the lift reportedly blew out, causing the equipment to crash down.

Detectives said one of the men was electrocuted by a Florida Power & Light power line, which caused the second victim to fall nine stories down after the platform they were standing on plummeted to the ground.

The man who was electrocuted is currently in stable condition, while the second worker who fell is in critical condition.

7News cameras captured investigators with Occupational Safety and Health Administration arriving on the scene to take a look around.

A work crew placed the platform that fell onto a truck and hauled it away.

FPL also arrived to the scene with a bucket truck to evaluate power lines close to the building. FPL officials said their crew de-energized a section of power lines, leaving approximately 2,300 customers without power. The power has since been restored.

Since investigators left the unoccupied building, 7News cameras captured zero work activity on the site as the investigation continues.
