Construction Worker Killed In Roof Fall At Palatine, Illinois Site

Enrique Cerroblanco Aguilar, 39, of Carpentersville, Illinois, was killed on May 22 after falling from a roof at a construction site in Palatine. The federal Occupational Safety and Health Administration opened an investigation the same day.

Falls remain the single largest cause of construction fatalities in the United States. They have been at the top of OSHA's annual "Fatal Four" list every year for more than a decade.

The employer's name has not yet been confirmed in public OSHA records. The investigation is open.

What the rule says, and how often it is violated

OSHA's fall protection standard for construction — 29 CFR 1926.501 — requires fall protection at heights of six feet or more in the construction industry. The protection can take several forms: guardrails, safety nets, or personal fall arrest systems. The standard has been in place since 1994.

It is also the single most-cited OSHA standard. Year after year, in the agency's annual top-ten violations list, "fall protection — general requirements" sits at number one.

The violations are not technical hairsplitting. They are workers without harnesses. Workers without anchor points. Workers on roofs without guardrails. Workers told to keep working without the gear that would have kept them alive.

A pattern across April and May

Three named construction or roofing fall fatalities have been publicly reported in the last six weeks:

• April 2026 — Florida: a Florida roofing employer was cited for willfully exposing employees to safety hazards after a fatal fall from a two-story residence. OSHA proposed $172,324 in penalties.
• May 11, 2026 — Marshall, Michigan: a 26-year-old roofer fell headfirst onto a concrete driveway while throwing shingles into a dumpster from a garage roof. MIOSHA opened an investigation.
• May 22, 2026 — Palatine, Illinois: Enrique Cerroblanco Aguilar killed in a roof fall at a construction site.

The Florida case is instructive. OSHA's "willful" classification — the agency's most serious category — indicates the employer was aware of the hazard and chose to ignore it. The proposed penalty exceeded $170,000.

The workforce, and the language gap

A significant share of U.S. residential construction workers are Latino immigrants. Workplace safety training that is provided only in English, in workforces where the workers' primary language is Spanish, is a documented and persistent failure. OSHA has acknowledged the gap.

The North America's Building Trades Unions and the Laborers' International Union of North America (LIUNA) have called for translated training requirements and for stronger enforcement of subcontractor safety in residential construction, where union density is lowest.

OSHA's investigation in Palatine continues. We'll publish more as findings are released.
