Grease exhaust cleaning is the Indiana Kitchen Fire Suppression process of removing grease, smoke residue, and grime from every component of a kitchen’s ventilation system, including hoods, filters, ductwork, and fans. In commercial kitchens, cooking produces grease-laden vapors that eventually cool and solidify, creating highly flammable deposits throughout the exhaust system.
Our team at Bradley Fire & Environmental Services is committed to researching and implementing innovative tools and equipment as well as using proven techniques that ensure our customers’ systems are cleaned to the highest standard and meet all NFPA 96 Standards and Codes.
Regularly scheduled cleaning is critical for safety, operational efficiency, and legal compliance.
Accumulated grease is highly flammable; a single spark can ignite it, causing fire to spread rapidly through ductwork. This is a leading cause of restaurant fires.
Most municipalities mandate cleaning schedules based on NFPA 96 standards. Failure to comply can result in heavy fines, failed inspections, or forced business closure.
A clean system effectively removes heat, smoke, and odors, preventing them from recirculating into the kitchen and dining areas. This reduces the risk of respiratory issues and discomfort for staff.
Clogged ducts force exhaust fans to work harder, leading to higher energy consumption (utility bills) and premature equipment failure. Routine maintenance can reduce maintenance costs by up to 30%.
Grease buildup can attract pests like rodents and insects and harbor bacteria or mold. It also prevents grease from liquefying and dripping back onto food below.
Many insurance policies require proof of professional cleaning to maintain coverage for fire-related incidents.
Professional services typically follow these steps to ensure safety and thoroughness:
Inspection: Assessing the entire system for high-density grease and mechanical issues.
Protection: Covering kitchen equipment and floors with plastic sheeting to prevent contamination.
Removal & Scraping: Manually scraping thick layers of solidified grease.
Chemical Degreasing: Applying food-safe chemicals to break down remaining residue.
Power Washing: Using hot water at high pressure (up to 2,000+ PSI) to flush out the ducts and fans.
Certification: Providing a certificate of cleaning for fire and health inspectors.
Kitchen exhaust system deficiencies are structural or operational flaws that compromise a kitchen’s safety and functionality. Addressing these issues is critical for Indiana Kitchen Fire Suppression, maintaining health standards, and ensuring operational efficiency.
Excessive Grease Accumulation: Grease and oily sludge build up in hoods, ducts, and fans, acting as highly flammable fuel that can ignite at temperatures as low as 370°F.
Improper or Missing Fan Hinge Kit: NFPA 96 codes require exhaust fans to be hinged with flexible weatherproof electrical cables to allow for proper cleaning and inspection of the duct and fan without damaging the unit.
Imbalanced Air Pressure: “Negative air pressure” occurs when the exhaust pulls out more air than the makeup air unit replaces, causing doors to slam or become hard to open.
Clogged or Damaged Filters: Grease filters that are saturated or damaged fail to trap vapors effectively, leading to faster buildup in the ductwork and increased motor strain.
Mechanical Wear: Worn fan belts, unlubricated bearings, and vibrating motors can lead to total system failure and loud, distracting noises.
Missing Access Panels: Lack of access doors in ductwork prevents technicians from reaching and cleaning internal grease deposits, leaving hidden fire hazards.
Miss or Improper Rooftop Grease Containment: Lack of rooftop grease containment on grease exhaust fans could cause significant grease buildup on the roof. Prolonged exposure causes roof membrane breakdown leading to leaks that eventually rot the building’s substructure.
Fire Prevention: Nearly 61% of restaurant fires are caused by cooking equipment, with grease-laden exhaust systems being a primary contributor. Correcting deficiencies significantly reduces the risk of a flash fire spreading through the building.
Compliance and Legal Safety: Regulatory bodies (like the NFPA, health departments, and fire marshals) mandate specific cleaning and maintenance schedules. Non-compliance can result in hefty fines, loss of insurance coverage, or forced business closure.
Staff Health and Safety: Proper ventilation removes smoke, steam, and toxic gases like carbon monoxide. Correcting airflow issues prevents respiratory problems, eye irritation, and heat exhaustion among kitchen staff.
Operational Efficiency: A clean, balanced system runs more efficiently, lowering utility bills and reducing the strain on HVAC systems that must otherwise work harder to cool an overheated kitchen.
Equipment Longevity: Regular maintenance prevents grease from corroding metal components and burning out fan motors, which can cost $500 to $2,000+ to replace.
Sanitation and Pest Control: Grease buildup is a food source for pests like rodents and cockroaches. It can also cause condensation to drip back onto food and preparation surfaces.
