What is a common method to prevent sparks and embers from entering the ventilation system?

Installing spark arrestors is a common method used to prevent sparks and embers from entering the ventilation system in commercial cooking operations. Spark arrestors are designed to capture and extinguish any sparks or embers that may be generated during the cooking process, especially in areas where open flames or high-temperature cooking appliances are used. By effectively blocking these ignition sources from traveling through the ventilation system, spark arrestors help to minimize the risk of fire within the ductwork and related infrastructure, enhancing overall fire safety.

Filters may help capture grease and particles, but they are not specifically designed for preventing sparks. Similarly, increasing duct sizes and reducing exhaust fan speed do not address the issue of sparks; rather, those actions may affect airflow and general ventilation but do not provide the protective function that spark arrestors offer. Therefore, the installation of spark arrestors is a targeted approach to enhancing fire prevention in cooking operations.
