Overview
- A local report first described a barbecue built against a dividing wall that sent smoke into a neighbor’s kitchen, and follow-up coverage on Friday and Saturday analyzed why the problem occurred.
- Journalists and engineers traced the intrusion to airflow physics: wind direction and urban wind corridors can carry exhaust horizontally into nearby windows when the grill’s outlet aligns with prevailing currents.
- Reports show that closing or glazing a balcony reduces incoming make‑up air and upsets pressure balance, while short, narrow, or convoluted chimneys weaken natural tirage and allow smoke to fall back into living spaces.
- Health authorities warn that charcoal combustion produces carbon monoxide and fine particles, so sources advise stopping use immediately if smoke returns and seeking professional testing for unsafe gas levels.
- Remedies require a qualified ventilation reassessment and structural fixes such as extending the chimney above nearby roofs, installing mechanical exhaust or scrubbers, or pursuing civil‑law nuisance claims to force remediation.
