Eleven Hospitalized After Carbon Monoxide Incident at M&S Charlton
Emergency crews were called to the Marks & Spencer store on Gallions Road in Charlton, south-east London, after eleven people were treated in hospital for carbon monoxide (CO) poisoning. Firefighters wearing breathing apparatus conducted a thorough sweep of the building and encountered elevated readings of CO, prompting a large-scale response to ensure the safety of staff and customers.
What Happened and Immediate Response
At around the time of the incident, responders isolated the area and began assessing the source of the gas. The fire service reported elevated carbon monoxide levels within the M&S premises and initiated ventilation procedures as a precaution while continuing to monitor the environment. The affected individuals were transported to local hospitals for assessment and treatment as a precautionary measure.
Current Situation and Authorities’ Steps
Workplace safety and fire investigators are reviewing the building’s systems to determine how the CO entered the premises. Investigators will assess heating, ventilation, and electrical equipment to identify potential sources, such as malfunctioning boilers, generators, or other equipment that can emit carbon monoxide when not operating safely.
Local health authorities and the building management are coordinating to ensure that anyone who might have been exposed receives appropriate medical follow-up. While CO incidents are relatively rare, they can occur in retail settings with complex HVAC and backup power systems, especially if equipment malfunctions or is poorly ventilated.
Advice for the Public and Workers
Carbon monoxide is a colorless, odorless gas that can be dangerous in occupied spaces. If you experience symptoms such as headaches, dizziness, nausea, or confusion, seek fresh air immediately and contact emergency services. Employers should ensure functioning CO detectors, regular maintenance of heating and ventilation systems, clear ventilation paths, and staff training on CO safety and emergency procedures.
For retailers and other businesses, routine risk assessments and clear emergency plans help prevent CO buildup. If CO is suspected, evacuate the premises and call the fire service rather than attempting to troubleshoot the problem on site.
What Comes Next
Authorities will publish a full report detailing the source of the carbon monoxide and any corrective actions required by the business. In the meantime, the M&S store may remain closed or operate with limited access as safety checks continue and investigations conclude.
Community and Legal Considerations
Incidents of this kind remind workplaces of the importance of robust safety standards. Staff welfare remains a priority, and affected workers will have access to medical oversight and support services as needed. Should there be any legal implications, they will be addressed by the relevant regulatory bodies and the retailer in coordination with local authorities.
