Meanwhile, paramedics treated 21 people, with one individual requiring transport to a hospital, according to a statement from the UK capital&#8217;s ambulance service on social media. The nature of the incident has not been disclosed.<\/p>\n\n\n\n<p>A fire brigade spokesperson later confirmed that the response to the event had concluded.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Police Review and Absence of Harmful Substances<\/h2>\n\n\n\n<p>Specialist officers from the London Metropolitan Police also attended the airport and carried out a thorough search. In an email statement, the force reported that no trace of any &#8220;hazardous substance&#8221; was found.<\/p>\n\n\n\n<p><strong><em>\u2192 <a href=\"https:\/\/aviacionaldia.com\/en\/2025\/08\/new-air-traffic-control-crisis-in-u-s-shortage-of-instructors.html\">New Air Traffic Control Crisis in U.S.: Shortage of Instructors<\/a><\/em><\/strong><\/p>\n\n\n\n<p>Meanwhile, videos began circulating on social media showing dozens of passengers waiting outside the terminal building.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Operational Impact and Airport Apology<\/h2>\n\n\n\n<p>Despite the evacuation, the departures section of Heathrow&#8217;s official website indicated that flights continued to take off. Via the platform X, the airport apologised to customers for the disruption and assured them it was &#8220;doing everything possible&#8221; to ensure flights departed as scheduled.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Recent Precedents<\/h2>\n\n\n\n<p>This latest episode follows another high-impact event in March, when the entire airport was shut down for nearly a day due to a fire at a nearby electrical substation. That situation led to the mass cancellation of flights and left thousands of passengers stranded around the world.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"related-topics\">Related
