Disposal of large hazardous waste containers

Full and sealed yellow hazardous waste containers are placed in the risk room (riskavfallsburet) by the loading ramp at Georg Morgenstiernes (GM) hus.
The code to the lock will be given after local training.
The renovator collects waste once a week.


Laboratory glassware and empty chemical containers

This type of glassware has a much higher melting point than ordinary glassware and should be disposed of in large hazardous waste containers. This also applies to empty chemical glass flasks/containers.

Empty gas containers
