Which type of door is especially beneficial for fire safety by restricting the spread of flames?

Fire doors are specifically designed to enhance fire safety by providing a barrier that restricts the movement and spread of flames, smoke, and heat during a fire. Unlike standard doors, fire doors are constructed from materials that can withstand high temperatures for a certain period, allowing individuals to escape and giving firefighters time to manage the situation effectively. They are often equipped with features such as self-closing mechanisms and intumescent seals that expand when exposed to heat, ensuring a tight seal to limit the passage of smoke and fire.

In contrast, hollow-core doors, which are typically lighter and not necessarily fire-rated, do not offer the same level of protection against fire spread. Revolving doors, while useful for controlling entry and exit in busy establishments, do not provide effective barriers in a fire situation. Similarly, sliding doors, often used for convenience, also lack the necessary fire-resistance properties.

The design and purpose of fire doors make them indispensable in buildings for managing fire risks and protecting lives and property in case of a fire emergency.
