P-9.3, r. 1 - Pesticides Management Code

Full text
5. Every pesticide must be stored in premises where the ambient conditions, in particular temperature, humidity and precipitation, are not likely to alter the pesticide, its container or label. It must also be stored in such manner that its content is not released into the environment.
That requirement does not apply to a Class 4 pesticide stored for personal use or for another person free of charge.
