Overview of the incident
Eleven people have been treated in hospital following a carbon monoxide (CO) incident at an M&S store on Gallions Road in Charlton, south-east London. Firefighters wearing breathing apparatus conducted a scan of the Marks & Spencer building and reported elevated readings indicative of carbon monoxide levels. The situation prompted an emergency response from local fire services, police, and medical teams.
Response from emergency services
Fire crews arrived at the scene and carried out a controlled sweep of the interior using specialised equipment and breathing apparatus. They checked multiple areas within the store and surrounding premises to determine the source of the CO and to ensure the safety of staff and customers. The responders worked in coordination with ambulance services to triage and transport affected individuals to hospital for assessment and treatment.
What is carbon monoxide and why is it dangerous?
Carbon monoxide is a colourless, odourless gas produced by incomplete combustion of fuels. In enclosed spaces, CO can accumulate quickly and prevent the blood from carrying oxygen, leading to headaches, dizziness, confusion, fatigue, or in severe cases, life-threatening conditions. Retail environments with gas-fired equipment, generators, or faulty heating systems require vigilant maintenance and rapid response to potential leaks.
Potential sources and prevention measures
In stores like M&S Charlton, potential CO sources include heating systems, boilers, or backup power equipment. Regular maintenance, proper ventilation, and functioning CO alarms are essential to prevent incidents. Employers should ensure staff are trained to recognise symptoms of CO exposure and know how to evacuate safely. Following an incident, authorities typically inspect equipment and ventilation systems to identify the culprit and prevent recurrence.
Impact on staff and store operations
Eleven staff members were treated in hospital as a precautionary measure. Their condition is not yet publicly described, but the response highlights the importance of workplace safety protocols and rapid medical assessment in potential CO exposures. The store may implement temporary closures or partial evacuations while engineers inspect the building’s systems. Customers with upcoming visits should monitor store updates and follow official guidance from store management and local authorities.
What happens next
Authorities are likely to conduct a thorough investigation into the source of the elevated readings. This could involve reviewing heating and ventilation equipment, gas lines, and maintenance records. Depending on findings, repairs or upgrades may be required to restore normal air quality and prevent future incidents. Employers are encouraged to review CO safety procedures and ensure staff have access to protective equipment and clear evacuation routes.
Staying safe after a CO incident
If you suspect carbon monoxide exposure in any setting, seek fresh air immediately and call emergency services. Symptoms can mimic common illnesses, so a high degree of vigilance is important. Regular maintenance of fuel-burning appliances and installation of CO detectors in workplaces are critical preventive steps.
Related guidance for businesses
Businesses should review local health and safety regulations, ensure CO detectors are installed where appropriate, and train staff to recognise and respond to potential gas leaks. Coordination with fire and medical services can help ensure a swift, effective response in future events.
