Dive summary:

• When the Occupational Safety and Health Administration found Accadia Site Contracting Inc. doing  water-main work in Niagara Falls the agency cited the company for not having wall supports in place to prevent a cave-in and other faults OSHA said it found.
• According to OSHA, there should have been support structures in place in the excavation because there were vertical walls 7 feet high, and regulations required a ladder every 25 feet to help workers get out quickly if an incident occurred.
• Accadia, which is based in Depew, N.Y., has 15 days to comply or appeal the penalty.
