OSHA Excavation Safety Standards in New York, NY
How Are Excavation Safety Standards Applied?
The federal Occupational Safety and Health Administration has established regulations regarding construction excavation safety. If a contractor or other party failed to comply with these standards and you were injured in a construction accident, you could be entitled to compensation.
If you or someone you love was harmed in a construction accident and someone other than your employer was to blame, you could be entitled to receive damages if the third party falls outside of the workers’ compensation system. The attorneys at David Resnick & Associates, PC, are skilled at evaluating construction accident claims and can help you determine whether the negligence of a third party caused or contributed to your injuries.
