Many businesses use grease traps, also known as grease interceptors, as part of a waste management system to prevent sewer system blockages from accumulated waste fats, oils, and greases. Safe grease trap design, training, and maintenance, as part of an overall workplace safety and health program, can prevent grease trap‑related incidents. To prevent hazards and potential injuries, grease traps must be properly covered at all times, and those covers must be adequately secured.
