Answer 1

Early spring of 1941.

"In January or February 1940, 250 Gypsy children from Brno in the Buchenwald concentration camp were used as guinea pigs for testing the Zyklon B gas. On September 3, 1941, 600 Soviet prisoners of war and 250 sick Polish prisoners were gassed with Zyklon B at Auschwitz camp I; this was the first experiment with the gas at Auschwitz."

"In the early spring of 1941 the Schutzstaffel (SS), along with doctors and officials of the T-4 Euthanasia Program began killing selected concentration camp prisoners in "Operation 14f13". The Inspectorate of the Concentration Camps categorized all files dealing with the death of prisoners as 14f, and those of prisoners sent to the T-4 gas chambers as 14f13. Under the language regulations of the SS selected prisoners were designated for "Special Treatment (German:Sonderbehandlung) 14f3". Prisoners were officially selected based on their medical condition, those permanently unfit for labor due to illness. Unofficially, racial and eugenic criteria were used: Jews, the handicapped, and those with criminal or antisocial records were selected. For Jewish prisoners there was not even the pretense of a medical examination, the arrest record was listed as a physician's "diagnosis"."

"Dec 8, 1941 - In occupied Poland, near Lodz, Chelmno extermination camp becomes operational. Jews taken there are placed in mobile gas vans and driven to a burial place while carbon monoxide from the engine exhaust is fed into the sealed rear compartment, killing them. The first gassing victims include 5,000 Gypsies who had been deported from the Reich to Lodz."
