Focus for ES-modifier tool

• NOT
• Company with risk assessment experts or who will
  make DU-CSR
• Company participating in pan-european activity
  regarding development of ES-concept under REACH
• HOT
• Formulating DU company/ Small trading company
  importing from outside of EU
• Basic knowledge how to make SDS for preparations
  (max. 1-2 persons in HSE department)
• No knowledge about self-classfication
• ES knowledge through national helpdesks/trade
  organisations

How to use ES-modifier

• Choose lifecycle stage (and user group)
• Insert substance data (directly/plug-in)(Today
  ES-Modifier is substance based future plans for
  preparations)
• Describe overall use according to DoU
• Choose models(Default models are Ecetoc TRA and
  EUSES)
• Describe specific details of use
• Make calculations and observe RCR results

37
Practical use of Descriptors of use (DoU)

• DoU is the main tool recommended in guidance for
• the identification of use
• and the headline in the ES
• DoU is input parameter to exposure models
• PROC gt Occupational exposure calculation
• PC/AC gt Consumer exposure calculations
• LCSSU/PC/PROC/AC gt ERCgtenvironmental exposure
  calculations
• Conclusion from case studies in RIP 3.2 and
  various workshops
• DoU is difficult to use/not reproducible
• More help is needed to find your way around in
  DoU
