University compliance part 2: Healthy ventilation by degrees

There are several aspects of ventilation hygiene that should be addressed, especially in a university campus, where clean, fresh air helps students and lecturers to concentrate and study, and also helps provide healthy living accommodation. Several ventilation maintenance disciplines also form part of essential fire safety measures, as Gary Nicholls, Managing Director of ductwork and Legionella risk experts, Swiftclean, explains.

A key compliance area for universities is the kitchen extract system, where grease deposits collect during cooking to form a serious potential fire hazard. Despite the trend towards healthier menus, fat, oil and grease particles naturally result from cooking, and, as airborne particles, they enter the kitchen extraction system, where the exhaust stream cools, depositing grease on the inside of the ductwork and forming a grease layer. It is a legal requirement, as part of fire prevention measures, to clean the entire extract system, comprising ductwork, canopy, plenum and fan, in accordance with TR19® Grease, to remove all traces of grease.
