• A. 10
• B. 15
• C. 20
• D. 22

Answer: (C)

Ionization smoke alarms are designed to detect fast-burning fires more quickly than other types, but their placement is crucial to ensure they function correctly without being triggered by non-emergency situations, such as cooking. The requirement to install these alarms at least 20 feet horizontally from a permanently installed cooking surface is established to minimize the likelihood of false alarms caused by cooking fumes and steam.

By following the guideline of maintaining a distance of 20 feet, it helps to ensure that the smoke alarm will accurately detect smoke from a fire, while reducing unnecessary disturbances from normal kitchen activities. This standard is essential for maintaining safety in living spaces, as it allows for effective fire detection without compromising daily routines.
