Regarding there are control the waste from Laboratory room to did not directly drain to rain gutter since 2 months ago.
Then QC have to collect all waste that come from Microbiological test in the container for at least one week after that move to waste area (near maintenance room)
However the waste from Lab are mostly media and have some growth of microorganism , It generate a bad smell ,
So while waiting the improvement of the drain system.
We will discard the waste from Lab room day by day , will not keep it to growth and accumulate in Lab clean room.
However could you update improvement plan , when?
