FETA Application based DSEAR Risk Assessment GuidesNo.1: Installation of an R32 Split Air Conditioning System.
FETA Guidance on Risk Assessments for compliance with DSEARFollowing the publication of our introduction to A2L refrigerants, a number of FETA groups have been working on guidance for the industry with regard to Risk Assessments required for compliance with DSEAR – the Dangerous Substances and Explosive Atmospheres Regulation. With the growing use of a number of refrigerants which exhibit flammability to various degrees, this is a topic area which may be new to many working in the industry. It should be noted that DSEAR now applies to ALL RACHP installations; not just those using flammable refrigerants.

A2L Refrigerants: Concept and Application Guide for Refrigeration Systems in the Scope of EN 378

This Guide covers the application of A2L refrigerants in refrigeration systems which are within the scope of EN 378. It does not cover air conditioning and heat pump systems and it does not cover small (integral) systems which are within the scope of a product standard. It is not a complete design guide. The Guide takes a risk assessment based approach – the hazards of A2L refrigerants are identified and the methods of mitigating these hazards are covered, in this case by following the appropriate standard (EN 378). A Quick Start Guide has also been written to cover the basics of the topic.

BRA Fact Finders

01 BRA-Factfinder – Risk Assessments and Method Statements [RAMS]This fully updated edition of the BRA Risk Assessments and Method Statements has been produced in line with current requirements and nomenclature. The latter is also reflected in the title of the document as Risk Assessments and Method Statements (RAMS).
02 BRA-Factfinder – New Lubricants for New RefrigerantsNew lubricants may be needed when using new refrigerants. Synthetic lubricants have been developed which behave in a similar way to the conventional lubricants, making the application of the new refrigerants straightforward.
03 BRA-Factfinder – Save £££s & the Environment at the Same TimeYou don't have to go far nowadays in the industry before you hear talk of Environmental issues, CFC phase out, ozone depletion and all the other Green terms that are bandied about. Of all the issues faced by the refrigeration industry, possibly the most important one is that of Energy.
04 BRA-Factfinder – Food Safety [Temperature Control Regs 1995]The new food safety regulations which came into force on 15th September 1995 revokes the Food Hygiene (amendment) regulations of 1990 and 1991. The following key points (°C) could help you.
05 BRA-Factfinder – Interpretation of Key Issues in EN378:2000 for Commercial RefrigerationBritish Standard BS 4434:1995 introduced terminology with which BRA members, sections of the commercial refrigeration industry and users may not be familiar. It also identified other aspects of refrigeration safety which BRA and the Institute of Refrigeration consider may be more demanding when using HFC refrigerants and transitional refrigerant blends.
06 BRA-Factfinder – Do not Mix RefrigerantsExisting systems should only be 'topped up' with the refrigerant already contained within them. Certain sectors within the refrigeration industry have advocated the uncontrolled topping-up of existing systems with a different refrigerant to the one they contain. This will form a 'cocktail' of chemicals in unknown proportions in the system.
07 BRA-Factfinder [Revised Aug-21]Selecting Copper Tube and Fittings – This note is an updated version of FF7 which provides guidance on selecting copper tube and fittings following revisions to BS EN14276-1:2020, BS EN14276-2:2020 and BS EN12735-1:2020.

Part 1 outlines the mandatory colour requirement for conductors in ac power circuits and Part 2 shows the BRA recommended colour designations for Extra Low Voltage (ELV) circuits (ac and dc) within the colour options allowed under the regulation.
15 BRA-Factfinder – Control of HFC Refrigerant SalesThe EU F-Gases Regulationsi require users of HFC refrigerants, such as R-134a, R-404A and R-410A, to hold certain minimum qualifications of competency in refrigeration, safety and handling and environmental issues.
17 BRA-Factfinder – Using Refrigerant GWP Values – A guide to selecting the appropriate dataThe purpose of this Fact Finder is to explain where Global Warming Potential (GWP) values for HFC refrigerants are derived from.
18 BRA-Factfinder – Code of Practice for isolation of a Display Cabinet evaporator from a Carbon Dioxide (R744) systemThis document is designed to provide guidance on the correct practice for Display Cabinet application on a system using Carbon Dioxide as a refrigerant.
19 BRA-Factfinder – A practical guide to using refrigerants with a temperature glideThis document is the second in a series of bulletins produced by the BRA following the publication of the PURR report (Putting into use Replacement Refrigerants). It is intended to provide advice for Service Engineers considering retrofitting high GWP systems.
20 BRA-Factfinder – Recovered Refrigerant and Recycling under the Hazardous Waste RegulationsFact Finder No. 10 has now been withdrawn as a number of changes have taken place with regard to the process of handling Hazardous Waste in the various parts of the United Kingdom. Whilst the process does vary, the key points are common to all of the UK.

HEVAC Air Handling Group

HEVAC Guide to Good Practice: Air Handling Units - 1991Air handling units vary greatly in size, function and complexity. Whether they be small or large, simple or complex, there are certain points to observe and pitfalls to avoid. It was the aim of this publication to guide the reader towards good practice, so that when the unit is installed it will perform in accordance with expectations. The components most commonly utilised within air handling units are dealt with individually and for each heading there has been gathered a list of do's and don'ts distilled from many years of experience. Fans though are not covered specifically since there is a separate HEVAC Fan Application Guide which should be referred to. With such an immense variety within the scope of air handling units the topics cannot be completely comprehensive, however, the m
