TSB : Laws And Regulations: Notes

Details

The effects of climate change can be seen worldwide. Protecting the climate is one of the most important responsibilities. However, this responsibility presents enormous challenges to all involved. The Kyoto Protocol outlines worldwide goals regarding climate protection, among other things. In addition to target reductions of carbon dioxide, this protocol also outlines target reductions for fluorinated greenhouse gases such as refrigerant R134a due to their high global warming potential. Numerous laws have been created for the automotive industry, for example at the European level. For example, chemical-climate protection regulations were put into effect on 08/01/2008 in Germany in order to define the European legislation in more detail. Provision (EU) number 1005/2009 Provision (EU) number 2037/2000 Provision (EU) number 842/2006 (from 01/01/2015: EU no. 517/2014) Provision (EU) number 706/2007 Provision (EU) number 307/2008 Guideline 2006/40/EU Chemical-climate protection regulations, recycling and disposal law (for Germany). Maintenance and repair work on the A/C system refrigerant circuit All individuals performing maintenance and repair work on vehicle A/C systems must have completed a training program and be competent in the work required. Other regulations may apply in addition to those of the European Union. The following general information applies: Operation, repair, decommissioning, take-back obligation When operating, repairing and decommissioning items that contain refrigerant, allowing the refrigerant to vent into the air is prohibited. Keep records on the quantities used during operation and maintenance so they can be presented to the authorities upon request. Refer to Audi ServiceNet, HSO Environment. A record sheet no longer needs to be kept in the EU due to a provision by the European Parliament in 2005. Other provisions may apply in countries that are not members of the EU. Distributors of the substances and preparations discussed above are obligated to accept these items back after use or to ensure they are accepted by a third party of their choosing. Maintenance and decommissioning of items containing refrigerant that are named in the legislation Substances and preparations named in this legislation may only be accepted by those with the necessary expertise and technical equipment. Criminal offenses and infringements of the law Infringement of the law in regard to the regulations and laws mentioned above. Acting intentionally or negligently during operation, maintenance work, or while taking products out of service. Willfully or negligently venting refrigerant into the air when operating, repairing or decommissioning items that contain refrigerant constitutes a violation of the laws and legislation described above. Observe the various technical regulations for handling and filling compressed gases (for example TRGS 400, TRGS 402, TRGS 407 TRGS 510 TRGS 725 / TRBS3145). NOTE: Parts of the Technical Rules for Hazardous Substances (TRGS) are listed (concerning vehicle manufacturers and workshops) below. TRGS 400 (hazard assessment for activities with hazardous substances) TRGS 402 (determining and evaluating the danger when working with hazardous substances: exposure from inhaling) TRGS 407 (activities with gasses - hazard assessment) TRGS 510 (storage of hazardous substances in transportable canisters) TRBS 3145 / TRGS 725 (transportable compressed-gas canisters - filling, keeping ready, internal transportation, emptying) NOTE: The Technical Rules for Compressed Gases (TRG), Technical Rules for Hazardous Substances (TRGS) and the Technical Rules for Operational Safety (TRBS) describe the state of technology, occupational safety and industrial hygiene as well as other substantiated industrial science knowledge for the provision and use of work equipment such as systems requiring monitoring during use or involving activities with hazardous substances. The provided technical rules apply to Germany. Different regulations and laws may apply in other countries. Observe the various technical regulations for handling and filling compressed gases (for example TRGS 400, TRGS 402, TRGS 407 TRGS 510 TRGS 725 / TRBS3145). General provisions for charging systems Definition of terms and explanatory notes Build and operation of charging systems Charging systems Does not apply to vehicle manufacturers or workshops. Charging systems are systems for filling mobile compressed-gas canisters. The charging system includes the premises and facilities concerned. Charging systems requiring a permit are ones used to transfer compressed gases to mobile compressed-gas canisters for supplying to third parties. Charging systems not requiring a permit are ones used for transferring compressed gases to mobile compressed-gas canisters for internal use only. Employees and employee instruction -- Employees are to be given instruction on the following topics before beginning work and at regular, appropriate intervals, at least once a year Hazards specifically associated with handling compressed gases The safety precautions, especially TRGS and TRBS. Procedures in the event of malfunction, damage and accidents The use of fire-extinguishing and protective equipment Operation and maintenance of the charging system based on the operating instructions. Charging systems are only to be operated and maintained by personnel. Aged 18 and above Possessing the necessary technical knowledge. Who can be relied on to work diligently. NOTE: Supervised work may also be performed by personnel that do not meet the requirements stipulated. Filling of pressure canisters (separate technical regulations apply to canisters from other countries and their charging that are not mentioned here). A compressed-gas canister may only be filled with the compressed gas declared on it and the quantity must comply with the stipulated pressure, weight or volume data (refer to pressure canister regulations). In the case of canisters approved for use with several types of compressed gas, the compressed gas with which it is to be filled and - if the compressed gas has a tc greater than or equal to -10 °C (tc = critical temperature) - the maximum permissible charging weight in line with TRGS must be marked on the canister prior to connection for filling. Compressed-gas canisters marked with the maximum permissible charge pressure in bar at 15 °C must be filled manometrically. If the temperature is not 15°C (59 °F) at the time of filling, the filling facility must determine the pressure based on the difference in temperature; it must be ensured that the permissible fill pressure for filling at 15°C (59 °F) is not exceeded in the pressurized canister. The charged canisters are to be checked by way of random pressure measurements to determine possible overfilling. Compressed-gas canisters on which the maximum permissible capacity is indicated by the net weight (filling weight, permissible weight of fill) in kilograms, must be filled gravimetrically. The canisters are to be weighed during filling and subsequently subjected to a weight check on special scales to check for possible overfilling. Scales used for this purpose must be calibrated. Under certain conditions, gases with a tc greater than or equal to +70 °C may be transferred volumetrically from compressed-gas canisters with a maximum volume of 150 l to compressed-gas canisters with a volume of maximum 1000 ccm. The TRGS conditions apply to the transfer of liquefied gas to cylinders used by workmen. Different TRGS apply to reservoirs in vehicles: -- For gas with tc greater than or equal to +70 °C (158 °F). -- For industrial gas mixtures with tc greater than or equal to +70 °C (158 °F). -- Liquefied extremely low-temperature compressed gases may be filled according to volume (volumetrically; reservoirs in vehicles excluded), if the charging system and/or the canisters is/are equipped with devices for measuring or limiting the volume of the charge and for measuring the temperature of the charge. When filling volumetrically, the permissible charge weight indicated on the canister must not be exceeded. To determine possible overfilling, the filled containers are to be checked gravimetrically on a calibrated scale or, provided that the compressed gases are not highly toxic, volumetrically. Volumetric checking requires the use of appropriate equipment. The charging and checking devices must be independent of each other. Charging and check measurements are to be performed by different people. Check measurements must be performed immediately upon completion of the filling process. Overfilled canisters must be discharged immediately and in a safe manner until the permissible fill is attained. The compressed-gas fill is then to be determined again. Specific TRGS 407 parts do not or only partially apply to canisters for liquefied, extremely low-temperature compressed gases which are neither flammable nor toxic; this does not affect the provisions of road traffic legislation. When filling compressed gas canisters with liquefied gases at charging temperatures less than or equal to -20 °C (-4 °F), the compressed gas canister (if the canister material has not been tested for temperatures less than or equal to -20 °C (-4 °F)) is not to be released from the charging system for transport until the canister wall temperature is greater than or equal to +20 °C (68 °F). Recycling and disposal law Laws and regulations for handling and disposing of refrigerants and refrigerant oils can be found in the chemical-climate protection regulation and in the recycling and disposal law. These are valid in Germany. Different laws and regulations may apply in other countries. Disposal of refrigerant Refrigerants intended for disposal are to be transferred to marked recycling containers, observing the permissible filling quantity. For example, refer to the chemical-climate protection regulation and the recycling and disposal law in Germany. Different regulations and laws may apply in other countries. Disposal of refrigerant oil Used refrigerant oils from systems employing halogenated hydrocarbons are to be disposed of as waste subject to special supervision. They are not to be mixed with other oils or substances. Proper storage and disposal must be ensured in line with local regulations. For example, refer to the chemical-climate protection regulation and the recycling and disposal law in Germany. Different regulations and laws may apply in other countries.
