Overview• What is REACh?• Why REACh?• Goals of REACh• Impacts of REACh• General Information• Information Requirements• Technical Dossier• Chemical Safety Report• Extended SDS

4

What is REACh?

• New EU Chemicals Regulation

• REACh : Registration, Evaluation, Authorization and Restriction of Chemicals

• REACh replaces 40 existing EU Chemical Regulations and Directives

5

Stages of REACh• Pre-registration: by December 2008• Registration: for substances ≥ 1 ton/yr• Evaluation: for high volume substances

which are of highest concern • Authorization: only for substances of

highest concern• Restriction: the Safety net

The European Chemicals Agency (ECHA) was established to manage the system

REACh Timeline

7

Why REACh?

• Lack of knowledge about chemical hazards on the EU market.

• Prior legislation was regarded as slow & burdensome.

• Incomplete information on existing chemicals vs. new chemicals.

• The burden of proof was on regulators.

8

Goals of REACh

• Enhance transparency and efficiency

• Close data gaps between existing & new substances.

• Manage and control potential hazards and risks to human health and the environment from the manufacture, import and use of chemicals within the EU

9

• REACh is a global business issue that will drive major changes in the way chemical businesses are organized

• REACh has the potential to be a major threat to supply chain continuity

• Clear and decisive leadership and management is needed

Impacts of REACh

10

Businesses need to understand how valuable these substances are to them, and plan to make effective business decisions

based on this knowledge.

Decisions made today will impact future business practices

11

No data = No market

12

REACh is a substance-specific regulation

PRODUCT

13

Product

A B C

D E F

G H

This product contains 8 substances

Therefore, this product will require 8

registrations

14

Multiple Expert Requirements• lawyers • lobbyists • communicators • IT-specialists • regulatory experts • physicians • Toxicologists • hygienists • researchers • process engineers • purchasers & logistics • marketing network • Export/Import coordinators

15

• Burden of proof has shifted to industry

• Industry will have to prepare a comprehensive document including:– Hazards– Risks– Risk management

Impacts of REACh

16

Classification & Labeling

• Under the new Global Harmonized System– Each substance will be required to undergo

classification

• Under REACh, this classification will be documented in the registration dossier

17

Identified Uses

• Use of the substance must be included in the registration

• If substance is hazardous, exposures need to be assessed

18

REACh Phases

Pre-Registration

SIEF Formation

Registration

Evaluation

Authorization

Restriction

19

• Phase-in Substances

• Pre-registration deadline December 2008

• Approx. 143,000 existing substances were pre-registered– ECHA received about fifteen times more pre-

registrations than expected

Pre-Registration

20

• Substance Information Exchange Forum

• Purpose:– Data sharing (compulsory)– Agreement on Classification and Labeling

SIEF

21

Registration

• Substances > 1 ton/year

• Develop Technical Dossier– Reduced requirements for intermediates

• Chemical Safety Assessment

• Classification

22

Technical Dossier

• Required for registration• Information requirements – dependent on

tonnage band• Contents:

– Information on manufacture & use of substance– Physical characteristics, toxicological &

ecotoxicological properties– Proposals for testing if appropriate– Indication of information submitted that should not be

made available on internet & why

23

This is not a regulation that requires testing

Proposals for testing….if appropriate

1. Provide the data available

2. Do the risk assessment

3. Determine data gaps

4. Drive testing requirements

Physical Tox/Ecotox Requirements

All Substances >1 ton/year


10 - 100 tons/year+


100 -100 - 1000 tons/year+


> 1000 tons/year+

29

Evaluation

• Substances > 10 tons/year

• Chemical Safety Assessment

• Requires detailed Chemical Safety Report– Required if a substance is dangerous, PBT or a

vPvB– Risk characterization on exposures from

intended uses– Risk Characterization

30

Chemical Safety Assessment

• Safety (physico-chemical)

• Human health• Evaluate data • Classification and labelling• Establish Derived No-Effect Level (DNEL)

• Environmental• Evaluate data• Classification and labelling• Establish Predicted No-Effect Concentration

(PNEC)

31

DNELs and PNECs

• DNEL: Derived No Effect Level

• PNEC: Predicted No Effect Concentration

32

Exposure Scenarios• Manufacture and intended uses

– substance life cycle (including disposal/recycling)

• Include• processes and tasks• frequency and duration (how often and how long?)• operational conditions• representative exposure data or modelling data• What risk management measures are required?

• For each human population exposed – Workers

– Consumers

– Indirect

• Included as an appendix to the Safety Data Sheet (SDS) – Now called an Extended Safety Data Sheet (eSDS)

33

Risk Management Measures

• Must address workers, consumers, and the general public

• For workers, consider…• Hierarchy of control• Principles of Good Control Practice (COSHH)• All routes of exposure (e.g., inhalation, dermal, ingestion)

• Determine residual risk

• Risk Characterization – compare exposure with the relevant DNEL

34

Environmental Assessment

PBT Persistent, Bioaccumulative & Toxic

vPvB very Persistent & very Bioaccumulative

35

Extended Safety Data Sheet (eSDS)

• Used to communicate hazard down the supply chain

• Increased requirements compared to current EU standard

• Exposure scenarios

36

Authorization• Required for all substances of very high concern

• Approx. 1,500-2,000 substances• Time limited

• Substances of very high concern are:• CMR (Carcinogen, Mutagen or Toxic for Reproduction Cat.1 or

2)• PBT (Persistent & Bioaccumulative & Toxic) or• vPvB (Very Persistent & Very Bioaccumulative & Toxic)• substances of equivalent level of concern

• Applicants must• demonstrate adequate control of risks or that socio-economic

benefits outweigh risks• develop substitution plans or inform on research to find

alternatives

• Restrictions can be applied to any substance

37

Conclusion

• Global Impact of REACh– US – TSCA Reform– China – ROHS– Taiwan– Canada
