Ventilation plays a vital role in the running of an enclosed workplace. It helps to carry fresh, clean air through the space, keep employees happy and healthy, and maintain the efficiency of the workplace on a daily basis. Regulations surrounding workplace ventilation have been put in place for good reason. When adhered to, any hot, humid or stale air within the space will be replaced with clean air at the right rate. The general rule of thumb is to keep at least 5-8 litres of fresh air within the space, every second for every occupant. This goes for any air that is clean and free of impurities that could cause workers to fall ill or be unhappy with the working environment. The vast majority of enclosed workplaces are required to have a certain amount of fresh air passing through the space. That includes anything from an office space to a commercial kitchen, a spray booth to a hospital, for example. Without proper ventilation, it’s very difficult to get a good amount of clean air into these enclosed spaces, and with many individuals coming and going throughout the day, it’s vital to provide clean air to keep these individuals healthy. There are some exceptions when it comes to enclosed workplaces and the standard ventilation guidelines. For example, a workplace designed for growing mushrooms needs a humid space for the product growth.
