Ventilation Exemption Letter – Mechanical Engineers Help

A Ventilation Exemption Letter could be on the rise after the Shelter in Place /Social Distancing is released.  Smaller restaurants rising to the occasion, updating their equipment to more of a “Take Out” or Grab and Go” environment to keep business going. Not to mention, Shelter in Place /Social Distancing, most likely difficult to attain in small restaurants, and innovation equally important. FOOD FACILITY PLAN REQUIREMENTS

Ventilation Exemption Letter – Why?

Ventilation Exemption Letters provided by mechanical engineers ensure a uniform standard for all cooking equipment used in a commercial restaurant. Whether used in the front dining room or in the back kitchen, the evaluation of all appliances is necessary. Many ovens, warmers, panini presses, or waffle makers may not need an extensive ventilation system to operate. Cooking equipment operation temperatures remain low enough, and the existing room ventilation low, to comply with ventilation rules. (1) (4)

Ventilation Exemption Letter Requirements

Mechanical Engineers require a “Letter of Engagement” signed by both parties, and payment of a fee before work will begin.

On the list, an application from the Santa Clara County Health Department. As well as, any specification sheets and emissions data to accompany the application, menu from restaurant, appliance operation instructions. In addition, pictures of the kitchen, because the Mechanical Engineer needs to see the placement of all appliances, sinks, counters, and doors to configure exhaust output. Together with, location pictures of the ceiling, vents in the kitchen, and dining area ventilation a formulation is made. Along with, a sketch of the entire restaurant both kitchen and dining area, either a designer sketch or a hand sketch is applicable. (2) (5)

With the above factors, the Mechanical Engineer can determine and calculate if there is enough ventilation to support the ventless ovens, panini makers, waffle makers. In most cases, no extensive repairs or additional vents need to be added to the restaurant. In all cases, cooking equipment installed correctly and maintained in accordance with the manufacturer’s recommendations works for the restaurant. Equally important, installed in well-ventilated areas approved for food preparation, and comply with all local building and fire codes. (3)

In addition, cooking equipment must be installed and maintained in accordance with manufacturer’s recommendations. Equally important, installed in well-ventilated areas approved for food preparation, and must comply with all local building and fire codes.
