1944 German Memo Regarding the Safety and Proper Use of Zyklon B.

English version.

Note there was a shortage of all disinfectants and a request had to be submitted to receive what was needed for disinfecting clothes etc. Where are all these requests? Do they exist? Are there requests for Zyklon B to use for what it has been claimed it was used for? I would bet not. Contradicts the narrative a bit.
