REACH Express Nb 2

Preamble (25) : « The responsibility to assess the risks and hazards of substances should be given, in the first place,
to the natural or legal persons that manufacture or import substances, but only when they do so in quantities exceeding
a certain volume, to enable them to carry the associated burden. Natural or legal persons handling chemicals should
take the necessary risk management measures in accordance with the assessment of the risks of substances and pass
on relevant recommendations along the supply chain. This should include describing, documenting and notifying in an
appropriate and transparent fashion the risks stemming from the production, use and disposal of each substance. »

Preamble (30) : « The requirements for undertaking chemical safety assessments by manufacturers and importers
should be defined in detail in a technical annex to allow them to meet their obligations. To achieve fair burden sharing
with their customers, manufacturers and importers should in their chemical safety assessment address not only their
own uses and the uses for which they place their substances on the market, but also all uses which their customers
ask them to address. »

According to REACH, risk assessment falls under a cycle which includes all the phases: manufacturing, use and disposal.

REACH defines risk assessment according two complementary principles:
1. Risk management,
2. Risk characterisation.

Risk management measures form part of the exposure scenario, which integrate the identified uses. Risk characterisation
consists in comparing experimental values with the on-site values. The comparison measures are related to the exposure scenario (annex I.7.10). The downstream user communicates up to his suppliers all identified uses (see our newsletter n° 1), thus he is part of the cycle and must not have a passive role.
