Fire door integrity and closure mechanism inspection involves assessing the condition and functionality of fire doors to ensure they effectively compartmentalize fire and smoke. This inspection verifies that doors seal properly, close automatically, and remain in good condition to prevent the spread of fire. By conducting regular inspections, potential issues such as damaged seals or malfunctioning closure mechanisms are identified and addressed promptly. This ensures fire doors operate as intended during emergencies, facilitating safe evacuation routes and containing fire outbreaks to minimize property damage and protect lives. Ultimately, it enhances overall fire safety in buildings and premises.
