The employer shall take the appropriate technical measures and define the appropriate work organisation measures to ensure the protection of workers against the hazards arising from the chemical and physico-chemical properties of chemical agents.
These measures shall cover, in particular, the storage, handling and isolation of incompatible chemical agents.
To this end, the employer shall take appropriate measures to prevent:
1° The presence in the workplace of dangerous concentrations of flammable substances or dangerous quantities of unstable chemical substances;
2° The risk of overflowing or splashing, as well as spillage by rupture of the walls of vats, basins, tanks and containers of any kind containing products likely to cause thermal or chemical burns.
