CO2 Carbon Dioxide Extinguisher Identification Sign - Safety Signs by Caledonia Signs

A CO₂ (Carbon Dioxide) fire extinguisher identification sign is used to clearly mark the location and purpose of a CO₂ extinguisher. This sign plays a vital role in ensuring that individuals can quickly identify the right extinguisher during an emergency, especially in workplaces or public buildings where multiple extinguisher types may be present. Proper labeling helps reduce confusion and enables a faster, more effective response to fire incidents.

CO₂ extinguishers are specifically designed for Class B fires (involving flammable liquids such as petrol, oils, and solvents) and electrical fires (including computers, machinery, and fuse boxes). The identification sign often includes symbols or text to indicate these uses, guiding users to the appropriate extinguisher for the situation. Using the wrong type of extinguisher can be dangerous and ineffective, so clear signage helps ensure safe and proper use.

These signs should be placed directly above or next to the extinguisher, at a visible height and location. Common installation areas include server rooms, electrical cabinets, laboratories, workshops, and offices—anywhere there is a risk of electrical or liquid-based fires. The signage ensures that staff and visitors are aware of the extinguisher's presence and its intended applications, even before an emergency arises.

In addition to promoting safety, using CO₂ extinguisher identification signs helps meet legal fire safety requirements, such as those outlined in the UK’s Health and Safety (Safety Signs and Signals) Regulations. Fire inspectors and safety officers look for proper signage as part of compliance checks. By clearly marking CO₂ extinguishers, organisations demonstrate their commitment to maintaining a safe and well-prepared environment.
