What are the standards for a restaurant’s kitchen exhaust systems?

NFPA 96 Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations.

The National Fire Protection Association (NFPA) is a global nonprofit organization that develops, publishes, and disseminates more than 300 consensus codes and standards intended to minimize the possibility and effects of fire and other risks. Virtually every building, process, service, design, and installation in society today is affected by NFPA documents. The latest NFPA codes and standards can be found on their website www.nfpa.org.

Keeping your kitchen exhaust systems clean and up to code is what companies like Great Lakes Power Wash (GLPW.NET) specialize in. They will help you evaluate your kitchen’s deficiencies and provide detailed reports which recommend solutions and provide quotes to do just that.
