In a restaurant kitchen, several main pieces of equipment may require fire protection due to their use of heat sources or potential for fire hazards. The specific fire protection measures can vary depending on local fire codes and regulations, but here are some common commercial cooking equipment that typically require fire protection:

1. Range: A commercial range or stove is a primary cooking appliance with open burners or a solid top. It often requires fire protection in the form of a fire suppression system, such as a range hood system with built-in fire suppression or an overhead fire extinguishing system.

2. Deep Fryer: Deep fryers are used for frying foods in hot oil or fat. These appliances can be equipped with fire suppression systems that detect and suppress fires using wet chemical agents designed to extinguish grease fires.

3. Griddle: A griddle is a flat cooking surface typically used for cooking items like pancakes, burgers, and eggs. Depending on its size and location, a griddle may require fire protection in the form of a ventilation system or a fire suppression system if it is located under a hood.

4. Broiler: Commercial broilers are used for grilling or charring food quickly. They may require fire protection if located under a ventilation hood, which could include a fire suppression system.

5. Charbroiler: Similar to broilers, charbroilers are designed for grilling foods with an open flame. They often require fire protection measures such as a ventilation system and fire suppression if located under a hood.

6. Pizza Oven: Pizza ovens, whether wood-fired, gas-fired, or electric, may require fire protection depending on their size and location within the kitchen. Fire suppression systems or ventilation hoods may be necessary.

7. Tandoor Oven: Tandoor ovens are traditional clay ovens used in Indian and Middle Eastern cuisine. Depending on their location and local regulations, they may require fire protection measures such as ventilation or fire suppression systems.

8. Wok Range: Wok ranges are specialized cooking equipment used in Asian cuisine. They typically involve high heat and open flames, making fire protection measures essential, such as fire suppression systems or proper ventilation.

It’s important to note that fire protection requirements can vary by jurisdiction and the specific layout of the kitchen. Local fire codes and regulations should always be consulted to ensure compliance with the necessary fire protection measures for commercial cooking equipment.
