Automatic smoke Vent - Keep Clear - Safety Signs by Caledonia Signs

Used to remind everyone on-site of the importance of maintaining unobstructed access to automatic smoke ventilation systems. These vents are designed to activate during a fire, releasing smoke and hot gases from the building to improve visibility and air quality. Keeping the area around them clear ensures they can operate freely and effectively, helping to protect people’s lives and limit property damage during an emergency.

The sign is necessary because even minor obstructions can seriously impair the function of an automatic smoke vent. Stacked materials, stored equipment, or temporary structures placed beneath or around the vent could prevent it from opening properly. This could lead to smoke accumulation, reduced visibility, and greater danger for occupants and emergency personnel. By displaying this sign, organisations emphasize that safety depends on keeping these crucial systems unobstructed at all times.

These signs should be installed in any building equipped with automatic smoke ventilation systems, particularly in large commercial or industrial facilities such as warehouses, factories, shopping centres, and multi-storey buildings. They are also important in public venues, schools, and offices where evacuation routes and smoke control are vital for occupant safety. Placing the sign near the vent or in highly visible areas ensures that workers, maintenance teams, and visitors remain aware of the requirement to keep the space clear.

Using an Automatic Smoke Vent - Keep Clear safety sign helps support compliance with fire safety regulations and reinforces a culture of preparedness. It reminds everyone that maintaining clear access to life-saving systems is a shared responsibility, not just a procedural rule. Regularly observing and respecting this signage ensures the vent system can perform its intended function in an emergency—protecting lives, aiding evacuation, and allowing firefighters to respond more effectively.
