Why is a grease trap or drain sometimes required in hood installations?

• A. To increase airflow
• B. To improve lighting
• C. To prevent grease from entering drainage system and minimize environmental impact and blockages
• D. To reduce fire risk

Answer: (C)

Grease control is the main idea here. In a commercial kitchen, fats, oils, and greases from cooking and dishwashing can travel down the drain with water and condensate. If these fats reach the building’s sewer or the municipal system, they can cool and solidify in pipes, causing blockages, backups, odors, and environmental contamination. A grease trap (or interceptor) captures most of that grease and solids before the wastewater continues on, allowing only relatively grease-free water to pass. This protects plumbing, reduces the chance of clogs and sewer problems, and helps meet health and environmental regulations related to grease discharge. Regular maintenance is needed to remove the collected grease so the trap stays effective. While minimizing fire risk can be a related safety benefit (less grease buildup on drains), the primary purpose is preventing grease from entering the drainage system and reducing environmental impact and blockages.
