Fire Door Keep Locked Shut - Safety Signs by Caledonia Signs

A "Fire Door Keep Locked Shut" sign is important because it identifies a fire-rated door that must remain securely closed and locked to maintain its protective function. These doors are typically installed in high-risk or restricted areas such as plant rooms, storage areas with flammable materials, or utility spaces where unauthorised access must be prevented while still ensuring fire containment.

Keeping these doors locked shut helps prevent the spread of fire and smoke through the building by maintaining the integrity of fire-resistant compartments. If left open or unsecured, the fire door cannot perform its role in slowing down the fire, which can significantly increase the risk to life and property.

The sign also helps organisations comply with fire safety regulations, which require proper signage on all designated fire doors and the maintenance of compartmentation systems. It informs staff and contractors of their responsibility to keep the door locked at all times unless it's in use for authorised purposes.

In summary, a "Fire Door Keep Locked Shut" sign is a critical reminder that supports fire protection, building security, and regulatory compliance, ensuring that key safety features function as intended during an emergency.
