The only thing customers should be able to smell in your restaurant is the delicious food being served. Even if you have an existing grease filter and kitchen ventilation system in place, the quality of the air inside your restaurant may surprise you.

Did you know that according to a recent UC Riverside study, commercial kitchen charbroilers can emit twice the amount of pollution as diesel trucks? In fact, according to the South Coast Air Quality Management District, commercial cooking is the largest source of directly emitted particulate pollution in California’s South Coast Air Basin.

But this isn’t just a problem in California, and it isn’t just charbroilers. All kinds of cooking produces grease, smoke, and particulates into the air which can lead to unpleasant environments that may even be harmful to respiratory health. Air quality has become a major concern in cities worldwide.

Across the United States, more and more people are associating clean, clear, odor-free air with the quality of a restaurant. And as more municipalities continue to create clean air ordinances and emissions regulations, many commercial kitchens are having to add pollution control units to their ventilation systems in order to stay in compliance with the increasing demands and environmental controls.

In all types of buildings, air balance needs to be carefully controlled. The amount of air that goes out must also come back in. But full-service commercial kitchens cannot rely soley on their HVAC system to supply 100% of the replacement air they need, so an independent make-up air supply is needed.

Air that is removed from the kitchen through an exhaust hood must be replaced with an equal volume of replacement air. If there is not enough replacement air (or make-up air), the building pressure will become negative which can cause various problems such as reduced exhaust hood fan performance or grease and smoke spillage from the hood.

That is why Make-Up Air Supply Units are at the heart of every commercial kitchen ventilation system. Designed to deliver fresh replacement air for proper air balance, a quality make-up air supply unit can also help keep cooking odors in the kitchen, minimize wear and tear on your exhaust hood, reduce energy consumption, and help maintain a comfortable working environment for employees.

Rooftop grease spills and related environmental contamination from kitchen ventilation systems cost businesses thousands of dollars each year. Managing and containing rooftop grease is a part of every commercial cooking operation. Commercial kitchens must also comply with a variety of state and federal requirements regarding grease control.

To address the many safety and environmental issues facing the restaurant industry, and in order to avoid fines and other problems like roof damage and serious fire risk, installing a rooftop grease containment system is a necessary investment. But with the leading cause of rooftop grease contamination being a poorly designed collection device, it pays to do your research.

A rooftop grease containment system is the single most important piece of equipment in the fight against rooftop grease. While exhaust fans are great at removing grease vapors from your kitchen, unless you install a rooftop grease containment system, that grease will eventually find its way onto your roof where it can cause damage, become a safety or fire hazard, create rooftop grease runoff that can contaminate the environment, and even attract pests and rodents.

Slip-resistant Shoes
You might think it won’t happen to you, but every year, slip and trip accidents cause millions of injuries, cost the workforce an estimated $8.6 billion and account for about 15 percent of all accidental deaths each year — second only to motor vehicles as a cause of fatalities. The best defense is keeping your work area free of clutter and wearing slip resistant work shoes or boots to help grip the floor even when additional factors such as grease and oil are present.

In the scope of kitchen exhaust cleaning, rooftop exhaust fans are an important and challenging part of the job. This is because there are more surfaces for grease to accumulate on such as fan blades and motor casing. And if it isn’t properly maintained, the system can fail due to heavy grease build up which puts stress on areas such as the fan motor, bearings and drive belt.

When cleaning fans, it is particularly important to make sure grease does not contaminate the roof. Grease and oil residue are detrimental to the roof and cause deterioration and structural damage including leaks, blistering, and cracks. They also pose a serious fire risk if left unaddressed. It’s important to make sure that no grease or oil washes off the roof during cleaning, which may result in environmental issues, code violations, and unsightly buildup around the exterior of the building.

The most common method used for cleaning upblast exhaust fans is pressure washing. Here are a few preventative steps you can take during routine exhaust fan cleanings to ensure the job is getting done effectively and efficiently without making a greasy mess of the roof. Continue reading

Pressure washing and high powered water brooms are great for all kinds of cleaning tasks, but if you’re dealing with a large area and want consistent results without streaks or “zebra stripes”, then a surface cleaner simply can’t be beat. It will also save you valuable time and effort on the job.

However, it’s important to remember that not all surface cleaners are created equally, and the Driploc 16″ Mini Spinner Surface Cleaner from HoodFilters.com is clear proof.
