3 3 22-10-2010 Risk assessment - Rapex Guidance Guidelines for the ‘ RAPEX ’ assessment procedure (2010/15/EC) RAPEX > Rapid exchange procedure Quick exchange of information Prevents to supply products with a serious risk Effectiveness and consistency of market surveillance Helps to ensure a high uniform level of consumer health Notification procedure Article 12 and and Article 11 of the GPSD (2001/95/EC) Article 11 > non-compliant products > notification Article 12 > products with a serious risk > RAPEX notification

4 4 22-10-2010 Risk assessment - Rapex Guidance The Guidelines are addressed to all the authorities of Member States RAPEX criteria the product is a consumer product, the product is subject to measures that prevent, restrict or impose specific conditions on its possible marketing or use ( ‘ preventive and restrictive measures ’ ), the product poses a serious risk to the health and safety of consumers, the serious risk has a cross-border effect.

21 21 22-10-2010 Risk assessment - Rapex For example

22 22 22-10-2010 Risk assessment - Rapex Product assessment – Power supply SELV terminals 230 V Isolation separation via a transformer Break down during the high voltage test

23 23 22-10-2010 Risk assessment - Rapex Risk assessment model – Product hazards  Identify all hazards that may lead to a consumer injury or health damage. Consider all consumers, including the vulnerable. Electric shock Overheating Fire …… (see Hazard sheet of model) (use for every identified hazard a new row)

24 24 22-10-2010 Risk assessment - Rapex Risk assessment model – Injury scenarios (1)  The exact hazard or defect in this product and the event that may result; the interaction of a person with the product during the intended and reasonably foreseeable use and the exposure to the hazard; the mechanism of injury. Connection to the power supply Phase is connected in most onerous way Transient (high power peak) on supply side High percentage of moisture Transformer isolation break down A person makes contact to the SELV circuit encompass The hands are wet An electric shock follows An earth leakage protection device shut down the supply

25 25 22-10-2010 Risk assessment - Rapex Risk assessment model – Injury scenarios (2)  The exact hazard or defect in this product and the event that may result; the interaction of a person with the product during the intended and reasonably foreseeable use and the exposure to the hazard; the mechanism of injury. Connection to the power supply Phase is connected to in most onerous way Transient (high power peak) on supply side High percentage of moisture Transformer isolation break down A person makes contact to the SELV circuit encompass The hands are wet An electric shock follows An earth leakage protection device shut down the supply Blue: the shortest possible scenario Red: the result

26 26 22-10-2010 Risk assessment - Rapex Risk assessment model – Injury scenarios (3)  The exact hazard or defect in this product and the event that may result; the interaction of a person with the product during the intended and reasonably foreseeable use and the exposure to the hazard; the mechanism of injury. Connection to the power supply Transformer isolation break down A person makes contact to the SELV circuit engripped (There are more scenario’s possible) (use for every scenario a new row) Blue: the shortest possible scenario

27 27 22-10-2010 Risk assessment - Rapex Risk assessment model – Type of injuries  For each hazard identified, describe the injury resulting from the injury scenario. If you select a hazard form the Hazard List, a typical injury(ies) will be filled in here. Make this more specific by describing both the injury and the body part. Click here to consult the Injury Scale. Electric shock (See also under burns as electric current can cause burns) Local effects (temporary cramp or muscle paralysis) - Electrocution

28 28 22-10-2010 Risk assessment - Rapex Risk assessment model – Severity of injuries  Assign from the Injury Scale: 1 to 4. Click into cell below. 1 Electric shock (See also under burns as electric current can cause burns) 2 Local effects (temporary cramp or muscle paralysis) 3 - 4 Electrocution

29 29 22-10-2010 Risk assessment - Rapex Risk assessment model – Probability of factors  For each hazard identified, estimate the probability for each step in the scenario (event, interaction and injury) e.g.: 1/10; 1/100; 1/8 Connection to the power supply 1/1 Transformer isolation break down 1/1000 A person makes contact to the SELV circuit engripped 1/4 For one product during the total life time

30 30 22-10-2010 Risk assessment - Rapex Risk assessment model – Calculated probability  Calculated value of probability factors, e.g. 1/10 x 1/100 x 1/8 = 1/8.000 (Connection to the power supply) 1/1 X (Transformer isolation break down) 1/1000 X (A person makes contact to the SELV circuit engripped) 1/4 = 1/4000 For one product during the total life time

31 31 22-10-2010 Risk assessment - Rapex Risk assessment model – Probability value  Select the scale value corresponding to the calculated value, e.g. 1/8.000 corresponds to "> 1/10.000" (Connection to the power supply) 1/1 X (Transformer isolation break down) 1/1000 X (A person makes contact to the SELV circuit engripped) 1/4 = 1/4000 = > 1/10 000 For one product during the total life time

32 32 22-10-2010 Risk assessment - Rapex Risk assessment model – Assumptions Connection to the power supply 1/1 Every product has the construction failure Transformer isolation break down 1/1000 Transients in the power source OR pollution of the transformer OR ageing of isolation layers, which can lead to bridging of the isolation in the transformer (in time the probability of failure increases); one off ten overall possibilities of a product becoming defect A person makes contact to the SELV circuit engripped 1/4 The terminals on the outside of the product OR extension leads connected to those terminals Or the connected external peripheral equipment parts under main voltage become directly accessible. If peripheral equipment is metal encased with a common earthing also the encasing can become connected to the main voltage.

33 33 22-10-2010 Risk assessment - Rapex Risk assessment model – Risks (1)  Combined result from the risk table: Serious to Low Risk

34 34 22-10-2010 Risk assessment - Rapex Risk assessment model – Risks (2)

35 35 22-10-2010 Risk assessment - Rapex Risk assessment model – Risks (3)

36 36 22-10-2010 Risk assessment - Rapex Actions if necessary All categories of preventive and restrictive measures ….., including measures: marking a product with appropriate warnings on the risks it may present; making the marketing of a product subject to prior conditions; warning consumers of the risks that could be posed by a product for certain persons; temporary ban on the supply, offer to supply and display of a product; ban on the marketing of a product and any accompanying measures; withdrawal of a product from the market; recall of a product from consumers; destruction of a withdrawn or recalled product. (see par. 2.2.1 of the guide)
