Kitchen Extract System
Most catering establishments feature a canopy extraction system within the kitchen to control the build up of heat, steam and grease emissions in the cooking area.
The filters in the canopy are the first line of defence against grease deposition but still allow the smaller particles to pass into the extract ductwork system. These deposits will accumulate over time and can pose hygiene and fire risks. Depending on how often a kitchen is in use will determine the recommended frequency of cleaning.
Many hotels, restaurants, leisure clubs and fast food operations now include the kitchen extract system on their regular maintenance schedule. There are potential legal implications to consider if the recommended frequency is not adhered too.
Laundry Extract System
Clogged filters and fans can quickly allow accumulations to build up in the extract ducting. These will not only reduce the health and comfort of working conditions in the laundry but will also constitute a potential fire hazard to all building occupants.
Fire Damper Testing
Fire and smoke dampers are fitted in ductwork where it passes through a fire compartment barrier. They are designed to shut when a specified temperature or fire/smoke condition is exceeded, preventing the spread of fire and smoke.
Fire dampers play a crucial role in a building’s fire safety system. If they don’t operate as designed fire can spread with rapid, lethal results. The fire dampers must be tested and maintained on an annual basis.
General Supply & Extract System
Most business’ have general Supply and Extract Ventilation Systems running through their buildings. Under current standards, clients air conditioning must be maintained to the new British standard, failure to do so would leave them open to litigation from anyone claiming respiratory problems were made worse by the air conditioning. The duty to comply with the health & safety Regulations concerning ventilation system maintenance and cleaning has been enforced since Jan 1st 1996. Now TR19 and BSEN 15780 have set new standards, Are you compliant?!
Entry points in the form of access panels are required to gain entry into the ductwork. The intervals for entry are specified in B8ES DW/144 and in B&ES TR19. Our fully trained technicians can fit access panels with the minimum disruption to our clients.
Once entry to the ductwork has been achieved various methods of ductwork cleaning are employed depending on the type of building, ductwork and contamination.
Dust particulate testing (NADCA)
Dust sampling can be conducted by using calibrated meters that provide an instant result or by utilising calibrated pumps that draw in air onto filter paper at a specific flow rate over a specific period of time. These quantities of dust are then compared and detailed reports can be compiled providing results and recommendations.
Microbiological testing (DIFCO/Contact Plates)
Microbiological testing services are a crucial requirement across many industries worldwide where products, processes and human health are at risk of being negatively affected by the presence and breeding of micro-organisms such as specific pathogens, bacteria, yeast and moulds.
Microbiology testing services help minimize the risk of potential damage by microbes and to ensure the microbiology quality of your products is maintained. To be carried out by a UKAS accredited body.
