CESA, the Catering Equipment Suppliers Association warns distributors that big things are happening in kitchen ventilation, with a number of British and European documents and regulations either in draft or about to come in to force.
The Association is involved in several of them and says that the equipment supply chain needs to be aware of the changes in the pipeline.
Solid Fuel Burning Appliances
There has been a significant increase in the use of solid fuel for commercial cooking, notably charcoal grills, due to the flavour they deliver and the theatre they can provide.
However, following an incident of carbon monoxide poisoning in a building adjacent to a restaurant using a solid fuel appliance, the HSE is drafting a new guidance document.
It will cover the ventilation requirements and follows the HSE’s consultation with CESA, CEDA and the FCSI. A new draft will shortly be published. CESA has argued that the new advice needs to be incorporated into the current information sheet, rather than in a new, separate sheet, so that engineers only need refer to one document rather than several.
Interlocking and UP/19
By law gas fired commercial catering appliances must be equipped with a ventilation system and the system must contain an interlock which will cut off the gas supply or prevent the operation of the appliances in the event of the mechanical ventilation system failing.
New installations should not be fitted with an override function, as was permitted pre-2001. The Institute of Gas Engineers and Managers (IGEM) is preparing to publish UP/19, a document covering the ‘design and application of interlock devices used in association with gas appliance installations in commercial catering establishments.’
This follows the withdrawal of Catering Information Sheet 23, which gave technical guidance for engineers in respect of gas-fired catering equipment. UP/19 will also replace technical bulletin 140, and is at an advanced stage of drafting.
UP/19 is also expected to lead to a briefing guide which engineers can use in respect to parts-per-million readings in kitchens. It will also cover the special ventilation requirements related to gas-fired equipment.
British Standard BS6173 specifies the requirements of the installation, servicing and maintenance of new and previously used gas fired catering appliances in catering establishments, burning 2nd or 3rd family gases. As part of the five year review into British Standards, the revision to BS6173 will come in autumn 2014.
The document gives guidance on the requirement for an interlock between a kitchen ventilation system and the gas supply, should there be a failure in the ventilation system.
It is not applicable to LPG catering installations, where appliances are sited temporarily in the open air, or in marquees or tents, or to LPG installations in mobile catering vehicles. It is not intended to apply to domestic premises or installations.
European Ventilation Systems Standard
CEN is the European Committee for Standardisation. CEN’s technical committee (TC) 156 has told CESA that the draft document prEN 16282 Parts 1-9, which covers the Kitchen Ventilation Systems Standard, will shortly be sent for a second public enquiry. This follows a significant number of amendments to the first document.
A working group (WG14) within CEN TC 156 is responsible for the production of the standard and comprises representatives from France, the UK and Germany.
The Kitchen Ventilation Systems Standard was initiated in 2004. The nine separate parts of the Standard, developed by the working group, are:
• General requirements
• Ventilated ceilings
• Air inlets and outlets
• Air ducts
• Aerosol separators
• Fire suppression systems
• Treatment of cooking fumes
• Capture and containment performance of extraction systems.
The eventual standard will be non-harmonised.
