1.0 INTRODUCTION

Fluorinated greenhouse gases (F-gases), are a group of chemicals that contain fluorine. F-gases are powerful greenhouse gases that trap heat in the atmosphere and contribute to global warming. In the EU, the use and emissions of F-gases are regulated by EU Regulation 842/2006. In Great Britain, the Fluorinated Greenhouse Gases Regulations 2009 (Statutory Instrument No. 261) applies.

Ozone-depleting substances (ODS) are a group of man-made chemicals that can cause damage the earth’s stratospheric ozone layer. They are being phased out, but can be found in older equipment. In the EU, the use and emissions of ODS is regulated by EU Regulation 1005/2009. In Great Britain, Statutory Instruments 2009 No.219 and 2011 No.1543, apply.

2.0 PURPOSE

This document provides guidance on how UCL Engineering, Maintenance and Infrastructure (EM&I) will comply with the EU Regulations relating to F-gases and ODS. It will detail the standards that UCL (E,M&I) require of its staff and Contractors to show compliance with statutory regulations and recognised best practices, across the entire UCL UK Estate. The University, specifically EM&I, has a responsibility to ensure that any PPM regime is robust, resilient and fit for purpose. Therefore, it is not appropriate to simply state the regulations to which the Certified/Qualified Person and/or Certified Company must adhere and to expect compliance to be achieved without further guidance. This document is the instrument for that guidance. The requirements within this document shall be used when procuring contractor services to perform PPM and reactive functions and shall be used as Key Performance Indicators to hold both Maintenance staff and Contractors accountable. Excellence in Customer Service is an expectation from all UCL Maintainers. This document supports the provision, by UCL, of world-class facilities for its students, staff and visitors.

3.0 SCOPE

This document details how UCL will contain, use, recover, dispose and record F-gas and ODS activity. The University has a duty of care to all Students, Staff and Visitors across its entire Estate and as such, this Standard Operating Procedure (SOP) shall be applicable to all UCL UK buildings, as listed on the UCL Building Register.

The only exception to this is with regards to leasehold buildings, where UCL does not hold the maintenance or repair obligations. In such areas, UCL Responsible Person – F-gas & ODS Operation shall ensure that the Landlord is carrying out such tasks to the same level of conformity and diligence.

4.0 RESPONSIBILTY

UCL (E,M&I) shall set the Procedures, PPM requirements and create the F-gas & ODS PPM Task Lists for action by maintenance staff and contractors. This document contains those requirements. It is the responsibility of UCL (E, M&I) to ensure that the F-gas & ODS PPM is carried out over the entire UCL UK Estate. General roles and responsibilities for management of Health and Safety within UCL and general responsibilities for F-gas & ODS are detailed in this SOP. This document shows specific responsibilities for staff within the UCL (E,M&I) department.

5.0 PROCEDURE

5.1 Identifying equipment / installations that contain an F-gas

All equipment or installations that contain an F-gas are subject to the general requirements of the Regulations.

All refrigeration systems should be labelled with the refrigerant type, usually on a nameplate mounted on the equipment. It will also be contained in an O&M manual, if there is one or in the handbook supplied with the equipment when purchased. Refrigerants are generally identified by an “R” number or by a trade name. The following two tables show refrigerants to which the Regulations apply.

R401A is 53% R22, 13% R152a and 34% R124

R401B is 61% R22, 11% R152a and 28% R124

R401C is 33% R22, 15% R152a and 52% R124

5.1.3 Trade Names

The fluids listed in Tables 1 and 2 above may be referred to using the “R-number”. R-numbers are a standardised nomenclature developed and managed by ASHRAE (the American Society of Heating Refrigeration and Air-conditioning Engineers).

Refrigerants are often sold under trade names, sometimes in association with the relevant R-number and sometimes with a completely different numerical designation. Table 3 gives some examples of trade names for F-gases commonly used as refrigerants and Table 4 provides some trade names for fluids commonly used in fire protection equipment.

HFC 227ea FM-200, FE-227, NAF-227

HFC 236fa FE-36

These different compositions are chosen by the fluid manufacturers to provide performance characteristics to suit different RAC applications.

Some HFC refrigerant blends contain both HFCs and HCFCs e.g. R401A and R408A. These HCFC blends fall under the EU Ozone Regulations. However, whether they are subject to the requirements of the F-gas Regulations will depend on the precise nature of the blend and the combined global warming potential of the mixture.

R22 is a very common HCFC refrigerant used in air conditioning. As an HCFC it is not covered by the F-gas Regulations, but does fall under the EU Ozone Regulations.

5.2 Complying with the EU F-gas Regulation

As ‘The Operator’ of systems that contain F-gases, UCL must comply with the obligations in the EU F-gas Regulation.

The actual obligations depend on the amount of refrigerant in each separate system. Two plants are considered to be separate if there is no interconnection between their refrigerant circuits (i.e. refrigerant cannot flow from one system to the other).

Table 5 summarises UCL’s obligations for each separate RAC system containing F-gas refrigerant. The text following the table provides more detail about each obligation.

Trade Names for HFC Refrigerants

Trade names are sometimes used with the relevant R number (e.g. Harp 134a) or with another number (e.g. R 401A is also Suva MP39)

The following trade names are for refrigerants that contain F gases:

AZ-20, AZ-50, Forane (FX56, FX80, FX100), Greencool 411B, Harp, Isceon (MO29, 39TC, MO49, 59, MO79, MO89), Klea, RS-24, RS-44, Suva (MP39, MP66, HP80, HP81)

The use of virgin HCFCs in UCL systems shall not employed for plant servicing and maintenance. This shall be recorded on all PPM Task Lists. After 2009 virgin HCFCs cannot be used for plant servicing and maintenance. This applies to all virgin HCFCs, even if purchased and stockpiled before the deadline. The UCL appointed DEFRA designated certified company to ensure that no virgin HCFCs are used in UCL systems UCL shall ensure that only Recycled or Reclaimed HCFC’s (see definitions below) until 31st December 2014.


Version 1.0 14-11-13 20

Use means the utilisation of HCFC refrigerant in the production, maintenance or servicing, including refilling of products or equipment. After the ban on the use of virgin comes into place only recycled or reclaimed HCFCs may be used in servicing and maintenance of refrigeration and air-conditioning equipment. The UCL appointed DEFRA designated certified company to ensure that only recycled/reclaimed HCFCs are used in UCL systems. The following definitions apply:

Recycled HCFC – is recovered HCFC gas that has been subject to a basic cleaning process (this might include mechanical filtering and moisture removal).

Reclaimed HCFC – is recovered HCFC gas that has been chemically

reprocessed to a specified standard.

Recycled HCFCs may only be used by either the undertaking which carried out the recovery (in most cases the refrigeration contractor) or the undertaking for which the recovery was carried out (the owner). Recycled HCFCs may not be placed on the market.

Reclaimed HCFCs may be placed on the wider market and used by undertakings other than the original contractor and owner. Reclaimed HCFCs must be held in containers labelled as such, with information on the batch number and name and address of the reclamation facility.

Section 7.2 Phase-out of recycled and reclaimed HCFCs

Articles 11.4 and 11.5. Applicable from 31st December 2014 to all sizes of RAC system.

UCL shall not employ the use of recycled and reclaimed HCFCs for plant servicing and maintenance after 31st December 2014. This shall be recorded on all PPM Task Lists

After 31st December 2014, recycled and reclaimed HCFCs cannot be used for plant servicing and maintenance of any UCL RAC system. This applies to all recycled HCFCs, even if purchased before the deadline. The DEFRA designated certified company to ensure that no recycled/reclaimed HCFCs are used in UCL systems after 31st December 2014. The DEFRA designated certified company to inform the Responsible Person – F-gas & ODS Operation, if they cannot use reclaimed/recycled HCFCs in UCL systems they have been asked to repair/maintain. This to be recorded on all applicable PPM Task sheets returned.

The ban on the “use” of HCFCs specifically means use for servicing and maintenance. It will remain legal to continue using RAC equipment containing HCFCs beyond the phase-out dates providing they do not require maintenance that involves the servicing and maintenance of the HCFCs in the system.

The Responsible Person – F-gas & ODS Operation shall Identify all UCL systems that contain HCFCs and plan a phased replacement/removal of the systems prior to 1st January 2015.

Section 7.3 Preventing/minimising HCFC leakage
