“DEFRA Guidance Odour Risk Assessments” ARE CHANGING TO “EMAQ+ Odour Risk Assessments for Kitchen Extracts”

• DEFRA Guidance: Previously the standard for kitchen extract system design and odour control, but withdrawn in 2017.
• Guidance Gap: Withdrawal left authorities and industry without clear guidelines for planning and nuisance assessment.
• EMAQ+ Guidance: New guidance developed by original DEFRA author, widely adopted by industry and local authorities.
• Airclean Alignment: Airclean will reference EMAQ+ instead of DEFRA in our documentation.
• Odour Risk Assessments: Airclean offers assessments to select suitable grease, smoke, and odour control equipment based on factors like dispersion, proximity, kitchen size, and cooking type.

The “DEFRA Guidance on the control of odour and noise from commercial kitchen exhaust” has been the go to guidance for the design of kitchen extract systems, and selection of odour control filtration since 2011, but was formally withdrawn in 2017.

This withdrawal was done to empower local authorities to make their own choices, but left Environmental Health, planning officers, and the industry, with no formal guidance to follow when approving planning applications, or assessing premises that were causing both noise and odour nuisances.

As a result of this a company called the Ricardo has employed the original author of the DEFRA guidance (Dr. Nigel Gibson) to recreate the guidance along with some updates, and offer this for use which is called “EMAQ+”.

This has been well adopted by local authorities and the industry alike, with many professionals (public and private sector) taking a course offered by Ricardo on the new EMAQ+ guidance.

For Airclean as manufacturers of grease, smoke and odour control equipment, is important for us to align with this, and as such you will start to see EMAQ+ referenced where previously you saw the DEFRA Guidance.

The most prominent place you will see this change is in our well used, “Odour Risk Assessment for Kitchen Extracts”.

Airclean carry out odour risk assessments daily, as a method to select suitable Grease, Smoke and Odour Control Equipment for potential clients designing and installing kitchen extract systems, and we offer a service where potential clients can simply complete these online, or via a short telephone conversation with us.

Odour Risk Assessments take into account the following :-

• Dispersion (Where does the extract discharge?)
• Proximity of Receptors (How close are the neighbours?)
• Size of Kitchen (Assessment of the kitchens output)
• Cooking Type (What type of cuisine, and cooking styles being used?)

Kitchen Extract Nuisance Control
Odour Risk Assessment & Filtration

Airclean is excited to announce that our first CPD-certified course is now available, focusing on the topic of kitchen extract nuisance control.

Key Points

• Airclean’s first CPD-certified course is now available, focusing on kitchen extract nuisance control and odour risk assessments.
• The course covers kitchen extract components, nuisance management, legislation, and standards.
• Learn how to conduct an EMAQ+ odour risk assessments and apply tailored solutions for various needs.
• Learn about filtration solutions and how they can be selected to suit any kitchen extract system.
• Ideal for professionals like ventilation distributors, HVAC consultants, engineers, and environmental health officers.
• Participants will receive CPD certificates and points upon course completion.

Learning Objectives

• To be able to understand and recognise the different sections of a kitchen extract.
• To be able to assess a kitchen for odour and nuisance in accordance with EMAQ+ guidance.
• To be able to identify and select appropriate nuisance control solutions.

About Kitchen Extract Nuisance Control

This course is designed to provide a comprehensive understanding of kitchen extracts, covering everything from their essential components to how they contribute to a safe and comfortable working environment.

Participants will gain insight into common nuisances associated with kitchen extracts and local regulations and requirements. The course delves into industry guidance and standards such as EMAQ+ and DW/172, offering a robust framework for understanding and managing these systems. One of the key features of the course is a detailed guide on conducting an odour risk assessment for kitchens, which is crucial for ensuring compliance with regulations and maintaining a pleasant environment.

The course is suitable for a wide range of professionals, including ventilation distributors, HVAC consultants and designers, engineers, and local authority environmental health or enforcement officers. Whether you are responsible for a small café or a large restaurant, this session will equip you with the knowledge and tools to effectively control odours and meet regulatory requirements.

Upon completion of the course, participants will receive CPD certificates and points, acknowledging their commitment to professional development and expertise in the field.

Technical Bulletin – HEPA Air Pressurisation Unit (APU) Set-ups

When we talk about how an Activated Carbon Filter works we use the word “Adsorption” to describe the process of molecules being removed from the air stream.  However, we often hear the more common word “Absorption” incorrectly used.

What is the difference between Adsorption and Absorption?

“Adsorption“

Is a process where atoms, ions or molecules from a gas, liquid or solid, stick or adhere to the surface of a material.  eg.  Activated Carbon Filter.

“Absorption“

Is a process where atoms, ions or molecules are drawn into or soak into a material. e.g. sponges or paper towels, taking on water.

Activated Carbon Filters

Airclean offers activated carbon filters in various styles, primarily as bonded panel filters. Multiple panels can be combined to form a carbon discarb filter cell for high carbon loading and increased airflow support. For odour control at lower levels, activated carbon impregnated media are available in both traditional bag filters and rigid bag filters.
