UK: The Building Engineering Services Association (BESA) has added its voice to concerns being raised across Europe that the F-gas revision proposals could increase the risk of accidents.
Revisions to the European F-Gas regulations, which the UK continues to apply, are expected to significantly increase the amount of flammable gas and high-pressure systems used by the refrigeration and air conditioning industry, but BESA is concerned there are not enough trained, competent people able to apply them safely.
Similar concerns were raised last month by AREA, the European contractors’ association. AREA also insists that failing to ensure that only competent contractors can work with alternative refrigerants risks widespread safety hazards and inefficient equipment.
While the proposals seek the inclusion of alternative refrigerants in training and certification schemes, they do not mandate the installation and maintenance of RACHP equipment with alternative refrigerants by certified installers only, as is the case currently with HFCs.
The UK has previously indicated that it would at least follow the European regulations, but the UK’s primary competence register REFCOM, which is managed by BESA, said there would need to be a significant rise in the use of new or alternative refrigerants to meet new targets set by the regulators to further reduce the amount of global warming gas available to the sector.
“The speed of change envisioned by the regulators will make it impossible for the industry to train up enough competent people in time to work safely with the alternatives like flammable hydrocarbons,” said BESA’s head of technical Graeme Fox.
“We are in the process of adopting the most far-reaching regulatory change to building safety in 50 years with the passing of the Building Safety Act, yet this threatens to create a whole new safety challenge that could easily be avoided by adopting a more realistic timetable,” he added.
The Association said it accepted the principle of the proposed changes to reduce the amount of greenhouse gas in circulation, but said measures must be practical both in terms of suitable equipment and the size of the competent workforce.
BESA is particularly concerned that the proposed changes will accelerate the adoption of flammable refrigerants in smaller air conditioning and heat pump solutions – many of which could be installed in homes.
“This could lead to a “wild west” scenario with untrained installers working on equipment they should not be anywhere near, including carbon dioxide systems which operate under much higher pressures than many installers have experienced,” said Fox. “It could also have unintended consequences for energy efficiency and carbon emissions.”
BESA also backed AREA’s calls for tighter regulation of alternative refrigerants by applying existing safe handling rules and by including them in the F-gas regulation’s leak testing requirements to reduce the risk of accidents.
