Technical conditions and measures
Use only in area provided with appropriate exhaust ventilation., Good work practice
required.
Organizational measures to prevent /limit releases, dispersion and exposure
Ensure operatives are trained to minimize exposures.
Conditions and measures related to personal protection, hygiene and health
evaluation
Wear suitable gloves tested to EN374., For personal protection see section 8.

3. Exposure estimation and reference to its source

Environment
A chemical safety assessment was performed according REACH Article 14(3), Annex I,
sections 3 (Environmental Hazard assessment) and 4 (PBT/vPvB Assessment). As no
hazard was identified, an exposure assessment and risk characterisation is not necessary
(REACH Annex I section 5.0).
