What type of door closer is commonly used on doors from hotel rooms to corridors?

• A. Self-closing
• B. Delayed-action
• C. Manual
• D. Pneumatic

Answer: (A)

The main idea is automatic closing to maintain fire containment and safe egress. In hotels, doors from guest rooms to corridors are typically equipped with a self-closing device so the door automatically returns to the closed and latched position after it’s opened. This ensures the door protects the corridor by limiting the spread of smoke and maintains the integrity of the building’s fire barrier, even if a guest forgets to close it.

Delayed-action closers would hold the door open for a period, which undermines that protection. Manual closers rely on someone to close the door, which isn’t reliable in a guest setting. Pneumatic refers to a type of mechanism rather than the standard function; while some closers may use pneumatic components, the common choice described is the self-closing type because it consistently re-closes without user action.
