Refrigeration Systems Regulation, Standards and Guidance

1. Refrigeration SystemsRegulation, Standards and Guidance Dr Dermot Cotter

2. Questions 1. When must standards be applied? 2. When must guidance be applied? 3. When must regulations be applied?

3. Purpose of Presentation Introduction to Regulations PER (PED) PSSR & PUWER DSEAR MHSWR Working to Standards EN378 (Safety and environmental requirements) EN60079 (Explosive atmospheres. Classification of areas)

4. PER (PED) Pressure Equipment Regulations 1999 All components of a refrigeration systems must have a CE certificate and be CE marked All new and modified refrigeration systems must have a GLOBAL CE certificate and EC mark Who can CE mark a refrigeration system? A notified body or a company certified by their notified body

5. PSSR & PUWER Pressure Systems Safety Regulations 2000 Applies to all systems Focuses on stored energy Systems with a compressor motor ≥25kW must have a WSE Systems must be inspected according to the WSE First Inspection completed before refrigerant is charged The WSE and inspection must be documented by a competent person Safety system testing (EN378) Provision and Use of Work Equipment Regulations 1998 Piping that contains a toxic or flammable substance must be inspected The inspection must be documented by a competent person

6. Flammability of Refrigerants 2L – lower flammability 3 – higher flammability 2 flammable 1 – non-flammable EN378 Classification CE certificate R22 R134a R513A R407A R407F CO2 R290 R1270 R600 R717 R1234yf R1234ze R32 R152a Non-flammable Flammable DSEAR 2002 Classification

7. DSEAR Dangerous Substance and Explosive Atmosphere Regulation 2002 Risk assessment must be carried out before system is put into use Eliminate or reduction of risk Classification of area – EN60079-10-1 Arrangement to deal with accidents, incident & emergencies Information & training Adequate normal and emergency ventilation Appropriate refrigerant detection Requirements of EN378 safety systems

8. MHSWR The Management of Health and Safety at Work Regulation 1999 Risk assessment should be carried out for all refrigerants (including toxicity and asphyxiation risks) Eliminate or reduction of risk Arrangement to deal with accidents, incident & emergencies Information & training Occupancy ventilation Appropriate refrigerant detection Requirements of EN378 safety systems

9. Standards and Guidance EN378 Refrigeration system and heat pumps – Safety and environmental requirement Requirements for: Where refrigerants and refrigerant quantities can be used Design of machinery room Emergency shower Refrigerant detection system concentration levels Occupancy and emergency ventilation requirements Maintenance O&M manuals

10. Guidance • EN378 – This is the legally recognised guidance • Institute of Refrigeration (IOR) Code of Practice: • A1 Refrigerants (HFC’s) • A1 & A2 Refrigerants • Carbon Dioxide • Ammonia • Safe Management of Ammonia Refrigeration Systems (FSDF)

11. Summary Ensure your refrigeration system complies to regulations: PED New or modified refrigeration systems must be purchased with a global CE mark and certificate PSSR & PUWER WSE for vessel and piping + EN378 requirements DSEAR Classification of areas + risk assessment + EN378 requirements MHSWR Refrigerant risk assessment + EN378 requirements
