A new mobile tool has been launched to support frontline workers with essential carbon monoxide (CO) safety advice and resources.

Developed by the Gas Safe Charity in partnership with the UK’s Gas Distribution Networks (GDNs) – Wales & West Utilities, Cadent, Northern Gas Networks, and SGN – the free ‘Think CO’ app will provide real-time guidance to safeguard vulnerable individuals across the UK.

The app has been designed for frontline workers such as Fire & Rescue Service teams, social workers, council staff, and charity workers, equipping them with instant CO safety information during home visits and emergencies.

Backed by a £43,000 investment over three years from the GDNs, the project forms part of ongoing efforts to reduce CO harm across the UK. It aims to train 750 frontline workers every year to recognise and address CO risks in vulnerable households.

Key features of the Think CO app include:

  • Instant Access to CO Safety Advice – Clear guidance on recognising CO poisoning symptoms, actions to take in an emergency, and regional CO alarm legislation.
  • Offline Access – Resources available without mobile signal, ensuring workers are supported wherever they are.
  • PSR & Fire Safety Information – Guidance on the Priority Services Register (PSR) and Fire and Rescue Service (FRS) home fire safety visits.
  • Ongoing Training Support – Continuous access to updated resources for workers who have completed Think CO workshops, e-learning or in-person training.

Sophie Stone, Vulnerability and Carbon Monoxide Allowance Coordinator at Wales & West Utilities, said:

“The launch of the Think CO app is a major development and will be critical in providing frontline teams with the resources they need to protect vulnerable individuals.

"It brings together vital CO safety information in one, easily accessible app to enable frontline workers to obtain information, wherever they are, allowing them to take swift, informed actions when it matters most.”

Since its launch in 2016, the Think CO programme has trained more than 4,000 frontline workers, reaching a wide range of organisations including Citizens Advice, The Scouts, and local authorities. The new app is the next step in ensuring those working with vulnerable communities have continuous access to life-saving CO safety resources.
