7 Workplaces That Require Good Ventilation

You might not realize it, but your business needs ventilation. Proper ventilation keeps moisture, smoke, dust, and pollutants out of the air and brings in good air.

If you're on a tight budget, you can get away with a low-quality ventilation system in some locations. However, certain businesses require a high-quality ventilation system to function properly and safely.

Let’s explore some of the businesses that rely on ventilation to do their work, and discover how proper ventilation plays a key role in their performance.

Commercial Food Service

A good ventilation system is an absolute must for restaurants and cafeterias full of heat-intensive equipment and fumes. This is because a ventilation system:

  • Gives a way for smoke to escape
  • Reduces chance of fire
  • Lowers air temperature
  • Decreases odours
  • Inhibits growth of toxic mildew
  • Minimizes respiratory health concerns for employees and customers

And let’s not forget one of the most important reasons for a good ventilation system: it’s necessary to pass fire and health inspections.

Some commercial food businesses could get by with an HVAC unit to pass inspection. However, many experience benefit from a more advanced exhaust system. Some benefits include lower utility bills and better air quality.

Food Processing Plants

Like commercial food service companies, food processing plants also benefit from quality ventilation. Without ventilation, gases contaminate food during processing. Air contaminants then change the flavour, odour, or colour of the food. Without proper ventilation, food service companies could even compromise the safety of the food, increasing health risks for the consumer.


Any welder knows that toxic smoke and fumes can build up quickly. Now imagine multiple welders in the same room, working on various welding projects throughout the day. Without ventilation, this environment could cause employees major respiratory problems.

Two types of exhaust fans are ideal for a welding shop:

  • Venting exhaust fan utilizes a fan and duct system; the fan pulls in air and empties it via a duct outside.
  • Recirculating exhaust fan works without ducts; it circulates air through the filter and releases it elsewhere in the building.

No matter the system, proper ventilation ensures workers breathe safe, non-toxic air.

Auto Manufacturing

In an auto manufacturing facility, employees use various tools and equipment to paint cars in a variety of striking colours. This job may seem safe at first, but there is a danger: fumes from the primer and paint contaminate the air. Without proper ventilation, the fumes put the employees at risk.

That’s why many of these facilities include a paint booth, an area specifically used for paint work. It includes an exhaust system, which expels contaminated air, and a make-up air system, which allows fresh air to enter at an equal rate to the exhausted air.

Other manufacturing painting plants use the same system when constructing furniture, boats, and airplanes.


With workers underground in dusty, stale air, you can likely imagine why ventilation is crucial to a mining operation. Many Canadian mines have diesel engine exhaust, mineral dust, and blast fumes floating around in the air. These dangerous substances are often cancer-causing agents that cause a variety of health issues when inhaled.

Ventilation not only removes dangerous substances from the air, but it also provides fresh, clean oxygen for miners. To achieve this, a mining system uses pipes, ducts, fans, HVAC systems, and air cleaning equipment.

Water and Sewage Treatment

In a water or sewage treatment plant, employees face chemicals such as methane gas and hydrogen sulphide on a regular basis. Inhaling these pathogens may lead to respiratory infection or other illnesses.

Consequently, it’s crucial that the facility includes a high-functioning ventilation system. With an efficient system, employees can breathe easy.

Manufacturing Plants

The law requires manufacturing plants to provide proper ventilation. This is because workers who have asthma or allergies will find their condition worsened with poor air. Additionally, ventilation helps employees to breathe easy and remain comfortable throughout their shift, whether or not they have pre-existing conditions. Ventilation also makes the temperature more comfortable and inhibits mold growth.

Does Your Business Need Good Ventilation?

Even if the business you work for doesn’t fit under one of these categories, you should still be aware of proper ventilation. This keeps the air breathable and minimizes health problems for your staff. The healthier your employees, the more productive and efficient they can become.

Keep in mind that you can rely on natural ventilation by opening windows and doors. However, this method is less effective at removing pollutants, and it does not reduce humidity (which impacts mold growth).

You can save a lot of money in health costs and repairs if you invest in a quality ventilation system.
