Special Order

A case of indisposition with slight symptoms of poisoning by hydrocyanic gas which occured today makes it necessary to warn all those participating in the gassings and all other SS members that in particular on opening rooms used for gassing₁ SS not wearing masks must wait at least five hours and keep at a distance of at least 15 metres from the chamber.  In addition, particular attention should be paid to the wind direction.

The gas being used at present containes less odorous warning agent and is therefore especially dangerous.

The SS garrison doctor declines all responsibility for any accident that should occur in the case where these directives have not been complied with by SS members.
