1 00:00:00,040 --> 00:00:04,840 VOICE-OVER: Welcome to one of ConsExpo Web's online tutorials. 2 00:00:04,960 --> 00:00:09,480 This video will give you insight into how to create exposure scenarios... 3 00:00:09,600 --> 00:00:14,000 and how they are incorporated into the ConsExpo Web software. 4 00:00:15,240 --> 00:00:21,080 Background information on default values used in generic exposure scenarios... 5 00:00:21,200 --> 00:00:24,000 and references to underlying sources... 6 00:00:24,120 --> 00:00:28,600 are available in the published ConsExpo fact sheets. 7 00:00:30,000 --> 00:00:35,320 An exposure assessment starts with the creation of an exposure scenario. 8 00:00:36,240 --> 00:00:40,160 The exposure scenario describes the consumer's use of the product... 9 00:00:40,280 --> 00:00:45,200 containing the substance of interest in a particular residential setting. 10 00:00:46,520 --> 00:00:51,360 In short, the four elements considered in an exposure scenario are: 11 00:00:51,480 --> 00:00:53,640 the product... 12 00:00:53,760 --> 00:00:55,480 the substance... 13 00:00:55,600 --> 00:00:58,440 the consumer or population... 14 00:00:58,560 --> 00:01:00,600 and the residential setting. 15 00:01:00,720 --> 00:01:03,040 To create the exposure scenario... 16 00:01:03,160 --> 00:01:07,400 you will need to enter information about these four elements. 17 00:01:08,160 --> 00:01:12,320 Typical variables to consider within the exposure scenario... 18 00:01:12,440 --> 00:01:15,920 relate to questions such as the following. 19 00:01:16,040 --> 00:01:20,760 The typical consumer: is it an adult or a child? 20 00:01:20,880 --> 00:01:23,720 Where is the product being used? 21 00:01:24,760 --> 00:01:28,040 How much of the product is needed? 22 00:01:28,160 --> 00:01:31,080 For how long is the consumer using it? 23 00:01:32,080 --> 00:01:35,640 How much of the substance is released? 24 00:01:35,760 --> 00:01:38,480 Is it a very volatile substance? 25 00:01:39,600 --> 00:01:45,680 Will the exposure scenario lead to dermal, oral or inhalation exposure? 26 00:01:45,800 --> 00:01:48,920 (SILENCE) 27 00:01:49,040 --> 00:01:53,400 As the number of consumer products and the ways in which they are used varies... 28 00:01:53,520 --> 00:01:56,720 information may not be readily available. 29 00:01:58,200 --> 00:02:01,360 Moreover, it is important in regulatory assessments... 30 00:02:01,480 --> 00:02:06,800 that exposure assessments are performed in a harmonised and standardised way. 31 00:02:06,920 --> 00:02:10,120 (SILENCE) 32 00:02:10,240 --> 00:02:13,960 ConsExpo fact sheets provide just that. 33 00:02:14,080 --> 00:02:17,000 They are an important part of the ConsExpo project... 34 00:02:17,120 --> 00:02:22,360 and fact sheet data are an integral part of the ConsExpo software. 35 00:02:23,680 --> 00:02:26,280 Users can access the fact sheet data... 36 00:02:26,400 --> 00:02:31,560 through a database within ConsExpo Web, shown later on in the video. 37 00:02:31,680 --> 00:02:33,640 (SILENCE) 38 00:02:33,760 --> 00:02:38,080 As of 2022, there are eight fact sheets. 39 00:02:39,200 --> 00:02:41,840 There is one fact sheet, the general fact sheet... 40 00:02:41,960 --> 00:02:46,120 dedicated to providing information on residential settings... 41 00:02:46,240 --> 00:02:51,040 population data and so-called anthropometric data. 42 00:02:51,160 --> 00:02:53,440 (SILENCE) 43 00:02:53,560 --> 00:02:58,320 The general fact sheet provides default information on room volumes... 44 00:02:58,440 --> 00:03:05,320 room heights, ventilation rates, body weights and skin surface areas. 45 00:03:07,240 --> 00:03:11,440 It provides data that is typical for the Dutch or European environment... 46 00:03:11,560 --> 00:03:15,160 but covers information from other parts of the world as well. 47 00:03:16,800 --> 00:03:22,120 The other fact sheets are based on product categories such as paints... 48 00:03:22,240 --> 00:03:30,080 cleaning agents, cosmetics, DIY products and pest control products. 49 00:03:30,200 --> 00:03:34,920 These product fact sheets were created following extensive literature research... 50 00:03:35,040 --> 00:03:37,560 and consultations with the industry... 51 00:03:37,680 --> 00:03:41,200 and were also based on product use information. 52 00:03:43,320 --> 00:03:48,600 The product categories are subdivided into product groups and subtypes. 53 00:03:49,720 --> 00:03:55,440 For example, the DIY fact sheet contains a group called 'glues and adhesives'... 54 00:03:55,560 --> 00:04:00,000 which in turn includes hobby glues, spray glues, et cetera. 55 00:04:01,360 --> 00:04:04,520 Exposure scenarios are created at the product level... 56 00:04:04,640 --> 00:04:08,440 and are defined by their exposure characteristics. 57 00:04:09,360 --> 00:04:10,600 The product fact sheets... 58 00:04:10,720 --> 00:04:14,040 connect the exposure scenarios for the relevant products... 59 00:04:14,160 --> 00:04:18,200 to the information required by the ConsExpo Web software. 60 00:04:18,320 --> 00:04:21,080 To do so, the fact sheets describe the scenario... 61 00:04:21,200 --> 00:04:25,440 and provide suggestions for the exposure models to use. 62 00:04:25,560 --> 00:04:29,280 (SILENCE) 63 00:04:29,400 --> 00:04:32,560 Furthermore, they provide recommended default inputs... 64 00:04:32,680 --> 00:04:35,440 for the requested exposure scenario. 65 00:04:35,560 --> 00:04:38,080 (SILENCE) 66 00:04:38,200 --> 00:04:42,600 Users still need to check if the input is appropriate for their own assessment... 67 00:04:42,720 --> 00:04:46,680 and provide specific product and substance information... 68 00:04:46,800 --> 00:04:49,760 such as the weight fraction of a substance. 69 00:04:49,880 --> 00:04:52,320 (SILENCE) 70 00:04:52,440 --> 00:04:55,800 A quality factor is assigned to the input parameters... 71 00:04:55,920 --> 00:04:58,960 to indicate the quality of the information. 72 00:05:00,280 --> 00:05:03,920 This 'Q factor' indicates how many underlying data... 73 00:05:04,040 --> 00:05:05,840 support the parameter value... 74 00:05:05,960 --> 00:05:09,280 and its appropriateness in the exposure scenario. 75 00:05:10,680 --> 00:05:13,000 The Q factor aids the user in assessing... 76 00:05:13,120 --> 00:05:16,240 whether the parameter value may be too uncertain... 77 00:05:16,360 --> 00:05:20,360 and whether they should perhaps look up more suitable information. 78 00:05:21,160 --> 00:05:25,720 Users can consult the database by selecting 'Use fact sheets'... 79 00:05:25,840 --> 00:05:29,000 at the assessment level or scenario level. 80 00:05:29,120 --> 00:05:31,520 (SILENCE) 81 00:05:31,640 --> 00:05:34,560 For example, if a user selects the product group... 82 00:05:34,680 --> 00:05:40,880 'DIY products', 'Glues', 'Hobby glues' for the usage phase... 83 00:05:41,000 --> 00:05:44,360 the database shows a screen describing the input parameters... 84 00:05:44,480 --> 00:05:46,920 for that particular scenario. 85 00:05:47,800 --> 00:05:50,920 The user can then decide to save this scenario... 86 00:05:51,040 --> 00:05:53,400 and complete the exposure assessment... 87 00:05:53,520 --> 00:05:59,520 that is enter the remaining information required before simulating the assessment. 88 00:06:00,720 --> 00:06:03,480 The fact sheets and ConsExpo Web software... 89 00:06:03,600 --> 00:06:06,600 are recommended as a basis for exposure assessments... 90 00:06:06,720 --> 00:06:13,000 within the context of the REACH regulation and the Biocidal Products Regulation. 91 00:06:14,240 --> 00:06:18,480 Please note that users are ultimately responsible for the parameter values... 92 00:06:18,600 --> 00:06:21,320 used in the exposure assessment. 93 00:06:21,440 --> 00:06:25,720 After accepting the default suggestions in the database for the scenario... 94 00:06:25,840 --> 00:06:30,600 users can make changes to these default inputs at their discretion. 95 00:06:32,680 --> 00:06:37,320 We hope this tutorial has helped you to familiarise yourself with ConsExpo Web... 96 00:06:37,440 --> 00:06:39,320 and its fact sheets. 97 00:06:39,440 --> 00:06:41,440 Our support does not end here. 98 00:06:41,560 --> 00:06:44,600 Visit the ConsExpo website for help pages... 99 00:06:44,720 --> 00:06:49,440 that provide information on ConsExpo Web and a user manual. 100 00:06:49,560 --> 00:06:54,640 You can also access the 'i' and '?' icons within the software... 101 00:06:54,760 --> 00:06:57,920 which are there to give you extra help when needed. 102 00:06:58,040 --> 00:07:00,480 If you still have questions or need assistance... 103 00:07:00,600 --> 00:07:09,400 please contact us at consexpo@rivm.nl.
