This Door to be Kept Locked Shut When Not in Use - Safety Signs by Caledonia Signs

" This Door to be Kept Locked Shut When Not in Use" signs are important because they help maintain security and safety by ensuring certain doors remain closed and locked when they are not actively being used. This is especially crucial for doors that lead to hazardous areas, restricted zones, or places where unauthorised access could pose safety risks, such as plant rooms, storage areas with dangerous materials, or fire-rated doors designed to prevent the spread of fire and smoke.

Keeping these doors locked helps prevent accidental entry, reduces the risk of theft or vandalism, and ensures that fire safety measures are not compromised. For example, fire doors are designed to slow the spread of fire and must remain closed and locked to perform effectively. The sign serves as a clear reminder to occupants and staff to respect these safety protocols.

These signs should be placed on or immediately next to doors that must be kept locked when not in use, such as fire doors, doors to hazardous storage areas, plant rooms, or secure areas within commercial buildings, factories, hospitals, or schools. Placement ensures anyone using or passing by the door understands the importance of keeping it locked.

By displaying these signs, organisations promote safety, security, and regulatory compliance. They reinforce good habits, help protect people and property, and ensure that vital safety barriers remain effective at all times.
