assessment method given
our constraints

L’Oréal
• Keep tools and
installations unchanged
• Treat small lab scale like
plant scale
Typical powder weighing
area on plants
• Get operators self
sufficient in assessing
own risks
Need for a new and user friendly tool
Practical and practicable so that it is practiced

Our approach

approach in risk assessment

L’Oréal
• X-functional team + strong EHS tradition like Sanofi and Ineris
• Provide elements wrt semi quantitative risk assessment
• Keep existing European CLP toxicity scale
• Better exposure control since unclear nano toxicology
• Capitalize on the implementation of CLP
Our focus is safety at the workplace
