Solid (and liquid) chemicals are generally deemed expired after 5 years. Do you have expired or useless chemical solids in your fridge, your freezer or your weighing area? Free the space!!!
REMINDER: Plastic containers have also a 5-year shelf life. After this time, the manufacturer no longer guarantees the purity of the product (plastic degradation products are released into the contents). You will find the date on the bottom of the jar, the jars without date are more than 10 years old !
You can put these products for disposal in the chemical rooms (IGBMC South 1085, 3086 or 4083, ICS 2070 or 3011, CBI E1043 or E3026). Each room has a zone designated for disposal of chemicals. The prevention assistants will collect them regularly for removal by the dangerous waste management department of university.
For any question, do not hesitate to contact the prevention assistants: assistants-de-prevention@igbmc.fr
