I remember news about a restaurant coming up in flames in a recognized mall a few months ago. It happened on a weekday, during lunch hour so there were a lot of guests, mostly employees on their lunch break, that were hurt. Initial investigation showed that it was due to a faulty gas tank that leaked.
Since then, public safety laws on commercial establishments have been strictly enforced, especially in restaurants and school. In fact there is a law that was enforced in 1996 called the Workplace (Health, Safety & Welfare) Regulations 1992. Commercial Kitchen Vent Cleaning was specifically mentioned in Paragraph 22.
The cleaning of kitchen ventilators, extractor fans and ductwork cleaning should be done in regular intervals with records on reports logged in and kept. This is important as majority of commercial kitchen fires start in the ductwork and can be prevented by regular and professional cleaning of kitchen vents.
Hygienic Maintenance Limited (HML) is a company founded by Roy Munford, Barry King and Steve Scott seventeen years ago. Their company specializes in the assessing, cleaning and monitoring of ducted air systems and specifically related air products. They are proud most of their workforce as most of their employees have been with them since the beginning, giving them more experience, work-wise.
