Environmental protection measures part 4

  2. 2.   Vented copper cylinders must meet the requirements of BS 1566.  Unvented cylinders must meet the requirements of BS 7206.  Thermal primary stores must meet the requirements of the hot water association (HWA). Vented, unvented cylinders and thermal stores PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  4. 4. PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM System without secondary hot water circulation If the furthest point of discharge is far away from The delivery point then the water will take time to arrive at the outlet when it is turned on. This is inefficient and waists money and energy.
  5. 5. PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM System with secondary hot water system With a secondary hot water return the point of delivery is closer to the furthest point of discharge. This is done by the means of : A pump on a 22 mm pipe which is located 450mm from the furthest point of discharge and returns to the cylinder entering it 1/3 from the top.
  6. 6. Forms of energy production which depends on the type of system are High carbon – produces high amounts of carbon Low carbon - produces low amounts of carbon Zero carbon - produces no carbon Carbon neutral.- the fuel that is burnt produces the same amount of carbon as it used up when growing Biomass are examples of carbon neutral fuels. Energy generation PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  7. 7.  Natural gas is used as a fuel for heating and cooking appliances and is usually supplied through the network of gas mains.

  8. 8. When commissioning systems you must do all of the below to make sure the system will run to the efficiency it is designed to give , this will meet the part L of the building regulations • Visually check all pipework. • Pressure test all pipework. • Flush and clean the system properly. • Test all components by running the system at normal to operating standards. • Check all controls, fittings etc for leaks/malfunctions. • By commissioning the system and showing the customer how to use the controls of the system will improve : • Efficiency. • Customer experience. • Save money and time.

  9. 9.  Hazardous waste regulations  Hazardous waste is essentially waste that contains hazardous properties which if mismanaged has the potential to cause greater harm to the environment and human health than non-hazardous.

  11. 11.  1. Eliminate - Use methods that avoid producing waste in the first place. 2. Reduce – Be aware of the waste you produce and try to minimise the amount you produce. 3. Reuse – reuse products and materials as much as possible to reduce waste. 4. Recycle – after products have been reused recycle. 5. Dispose – if products can not be eliminated, reused or recycled then dispose of the waste properly in the right skip. Dealing with waste PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  12. 12.   It is illegal to dispose of waste in any outer place than registered commercial or private sites.  Recycling is an energy efficient and environmental friendly way to dispose of scrap waste. No Fly-tipping PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  13. 13. Water Supply (Water Fittings) Regulations 1999 The purpose of the Water Regulations is to: • Prevent contamination of a water supply.–(use back flow protection) • Prevent the waste of water.- (repair any leaks or dripping taps) • Prevent the misuse of a water supply.- (using water for not what its intended for) • Prevent undue consumption of water. – (maximum flush for wc is now 6L) • Prevent erroneous measurement.- prevent stealing ( by-passing the water meter ) PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  14. 14.   The Globally Harmonised system of classicisation and labelling of chemicals (GHS) provides a standardised single system that identifies substances across the world, this is an international agreement and not international law.  To implement the (GHS) legally across the world each country need to introduce this system into there own legislation  The EU have adopted the system by the means of the regulations on classification of labelling and packing of substances known as CLP regulations Regulations on classification of labeling and packing of substances PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
