The majority of restaurant fires originate on the kitchen cooking appliances and flare into the kitchen exhaust system. Regular maintenance of a facilities kitchen exhaust system is one of the best defenses against fire hazards. By keeping these systems working at their best, they will evacuate the smoke and grease out of the building and produce a cleaner, cooler kitchen and better working environment for staff.According to National Fire Protection Association Standard 96, kitchen exhaust systems should be inspected by a properly trained, qualified and certified company or individual.
