“No worker’s life should end in a trench. Cave-ins during excavations are some of the most common and grisliest causes of worker fatalities in construction, yet they are entirely preventable,” said OSHA Administrator Dr. David Michaels.

Since 2003, more than 200 workers have died in trench cave-ins, and hundreds more have been seriously injured. The new guidance materials detail proper shoring and sloping; evaluations by competent persons; means of access/egress; atmospheric hazard testing; and protective systems. In addition, the guidance covers requirements under OSHA’s excavation standards.

“I am deeply troubled by the continued violations of OSHA’s trenching standards, many of which bring tragic results,” Michaels added. “These new educational materials provide clear guidance on the necessary steps that employers must take to protect workers in trenches.”

The new guidance materials are free and can be accessed online:
