In October 2007, Soho in central London went into panic after a sharp, burning smell spread through the streets. People reported stinging eyes and a “chemical-like” odor, so emergency crews sealed off the area and searched for hours in full protective gear. The cause? Not a chemical leak — but a Thai restaurant dry-frying bird’s-eye chilies to make an extra-hot chili paste. The capsaicin in the air created a spicy cloud so strong it mimicked a chemical irritant. Once firefighters traced the smell back to the kitchen, the alert was lifted and the streets reopened. Today, the incident is a famous reminder that how strong cooking odors can trigger public safety alerts.
