Two men died and another was seriously injured when the ground gave way under the boom lift they were working from in Hermosillo, Sonora, Mexico, last Wednesday.
The men were planning to use the Genie telescopic boom to paint the building located above an underground parking garage at a shopping mall on the west side of the town. The boom was fully retracted and slightly elevated as they drove it into position when the concrete panel below the lift gave way. The lift dropped into the void below, and from what we have been told, the men were catapulted to the ground.
The three were rushed to the hospital, where two of them, 25 and 40, died within 24 hours of arrival. It seems that while badly injured, the third man is expected to survive.
This is yet another case of not checking the ground bearing capacity of such locations. The lift is either a Genie S-65XC or S-85, which weigh 11.5 and 18 tonnes respectively.
There is an argument that when working on a cast concrete surface above a parking garage, it is safer to use a lighter platform, such as a spider lift. So many people's lives are profoundly affected when such incidents occur. Family, friends, and final work colleagues and others on site. Our hearts go out to all of them.
Finally, a big thank you to those based in the area who sent us photos from the scene – hopefully others will learn from this incident

Also to say that assuming the platform was raised to only approximately 3m off the ground (which is what appears to be in this incident), it shows the importance of wearing a harness at all times.

Would also appear, based on what you say here, that no harnesses were used. This would not have prevented injuries but, looking at the pictures and seeing how the platform ended up it could have kept the men alive.

I am NOT saying this to speak ill of these operatives but rather to promote the importance of harnesses in boom platforms as they are capable of catapulting the operatives out of the basket without one.
