"Workers at this site were exposed to falls of up to four stories from unguarded roofs, scaffolding, aerial lifts, open-sided floors and window openings," said Rosemarie Ohar, OSHA's New Hampshire area director. "This is particularly disturbing since falls are one of the four leading causes of death in construction work."

New Generation Construction LLC of Peterborough, N.H.; D&F Builders LLC of Hooksett, N.H.; and Enrique Reynoso of Lynn, Mass., were cited. OSHA began its inspection Feb. 2 when an inspector noticed fall hazards while driving by the Dustin Rd. jobsite.

New Generation, a framing contractor, faces $49,000 in fines. The company was issued two willful citations for lack of fall protection for employees working from an aerial lift and exposing employees to falls from unprotected window openings and open-sided floors. OSHA also issued a repeat citation for no fall protection for employees working on scaffolding, and three serious citations for missing stair rails, missing stairway guardrails and an unsafe portable ladder.

D&F, which was installing siding, was fined $15,600 — one willful citation for inadequate fall protection for employees working on scaffolding and five serious citations for unsecured and improperly erected scaffolding, no head protection for employees working beneath scaffolding, an inadequately guarded table saw and an unsafe ladder.

Reynoso, a roofing subcontractor, was fined $3,000 for four serious fall protection-related citations.

Each company has 15 business days from receipt of its citations to comply with or contest them.
