Carbon Monoxide Detectors in Commercial Properties

November 7th, 2024

Last updated: December 10th, 2024

Carbon monoxide (CO) detectors in commercial properties are essential to safeguard staff, customers, and anyone using the premises from the dangers of carbon monoxide poisoning.

CO is a colourless, odourless gas produced by burning fuels like gas, oil, coal, and wood, and it can become lethal in enclosed spaces, and people may not even notice it building up. Although CO detectors are commonplace in homes, commercial properties must also stick to certain regulations to ensure safety.

Why Carbon Monoxide Detectors Are Essential in Commercial Properties

Carbon monoxide poisoning can occur anywhere fuel-burning appliances are used, and commercial properties are no exception. In settings such as restaurants, hotels, offices, and shops, boilers, ovens, and heating systems are common sources of CO. With prolonged exposure, CO can lead to serious health risks.

Detectors are, therefore, essential as they provide an early warning, allowing occupants to evacuate or ventilate the space before CO levels reach dangerous concentrations.

There are numerous forms of legislation that address the use of CO and fire detection methods. A couple of examples of legislation can be found below.

The Health and Safety at Work Act 1974

The Health and Safety at Work Act requires employers and building owners to ensure the safety and welfare of everyone on their premises. Although the Act doesn’t specifically mandate CO detectors, it requires employers to manage risks associated with harmful substances. Under this duty of care, businesses should assess risks from CO-emitting appliances and ensure proper precautions, which may include CO detectors, are in place to mitigate exposure.

The Gas Safety (Installation and Use) Regulations 1998

For properties using gas appliances, this regulation is crucial. While it primarily focuses on the installation, maintenance, and inspection of gas appliances, it also mandates regular checks to prevent CO leaks. Many commercial property managers install CO detectors as a supplementary safety feature, especially in high-risk areas, to ensure compliance and enhance protection.

Choosing and Installing CO Detectors in Commercial Properties

When choosing CO detectors, commercial property managers should ensure they are compliant with BS EN 50291-1:2018 standards, which specify safety requirements for CO detectors in domestic, recreational, and light commercial premises. Detectors that meet this standard will reliably alert occupants to harmful CO levels. It is crucial that they are checked and maintained, usually along with fire prevention and alarm systems. Though not specifically a fire alarm in itself, a CO detector alerts you when a combustion appliance in your property emits dangerous carbon monoxide.

Types of CO Detectors

• Battery-Powered Detectors: These are cost-effective and easy to install, but batteries must be replaced regularly. They’re ideal for smaller properties or as an additional safety measure.
• Mains-Powered Detectors with Battery Backup: These offer consistent power with battery backups in case of outages. They’re ideal for larger properties and areas with high CO exposure risks, such as kitchens or boiler rooms.
• Smart Detectors: These devices connect to mobile phones or smart building monitoring systems, allowing property managers to receive alerts even when the property is vacant.

Placement of CO Detectors

Placement is key for effective CO detection and for building compliance. For instance, detectors are required in close proximity as some appliances.

Detectors should be installed in areas where CO build-up is most likely, such as near fuel-burning appliances, kitchens, boiler rooms, and garages. Avoid installing them near windows or doors, as ventilation can delay detection. Ensure detectors are at breathing height or according to the manufacturer’s recommendations for maximum efficiency.

Regular Maintenance and Testing

Once installed, CO detectors require regular testing and maintenance. The Health and Safety Executive (HSE) recommends that businesses check detectors monthly and replace them according to the manufacturer’s guidance, typically every 5-7 years. Regular maintenance of gas and heating appliances including boilers, as required by the Gas Safety (Installation and Use) Regulations, also helps to reduce CO risk, ensuring that the appliances are functioning efficiently and safely.

Consequences of Non-Compliance

Failure to manage CO risks adequately can result in fines, legal liabilities, and even criminal charges if negligence leads to harm. Insurers may also deny coverage if CO-related incidents occur in properties without detectors, leaving businesses financially exposed. Beyond legal consequences, having CO detectors demonstrates a commitment to staff and customer safety, reinforcing trust in the business.

A Safer, Healthier Environment

Carbon monoxide detectors are more than a legal or regulatory obligation – they’re an essential part of creating a safe environment in commercial properties.
