In a suburban area like Burr Ridge, exposures frequently occur in environments people don’t automatically connect to “chemical injury,” such as:
- After-hours cleaning and disinfecting in commercial buildings
- Maintenance and repair work where ventilation or protective equipment is overlooked
- Contractor-led projects where safety responsibilities are shared or unclear
- Nearby industrial activity that can affect air quality during certain work conditions
Because these scenarios can involve multiple employers, vendors, or property operators, the first challenge is identifying who controlled the worksite and who had the duty to prevent harm.
