  The filter insert 
            is exhausted if gas enters through the mask. If using filter "J", 
            first move  around in the open air for approx. 2 minutes so that 
            a certain amount of moisture from the  breath may gather in the 
            filter insert. Under no circumstances should filters be changed 
             inside gas-filled rooms. |

          Personnel 
  A 
            disinfestation squad consisting of at least 2 members is employed 
            for each disinfestation  project. The fumigation chief is 
            responsible for the fumigation. His particular duties 
            are inspection, airing, release and safety measures. The 
            fumigation chief is to appoint a deputy  in case he has to leave. 
            The orders of the fumigation chief are to be followed without delay. 
            
  Untrained persons or persons who are trained but who do not 
            yet hold a certificate may  not be called in to work on gassing 
            operations, nor must they be taken into gas-filled rooms.  The 
            fumigation chief must also know where to contact his personnel. 
            Every person must at  all times be able to prove that he has 
            official authorization for the use of prussic acid for  [pest] 
            extermination purposes.   |

          | 12.  | 
          Take over keys (every door 
          key).  | 
        
          |   | 
            | 
        
          |  IX   | 
          The strength of the gas and 
            the time required for it to take effect depend on: 
             
       The type of vermin 
                  The temperature 
                  The amount of furniture in the 
            rooms       The imperviousness of the 
            building. 
  For inside temperatures of more than 5 degrees 
            Cent., it is customary to use 8 g prussic  acid per 
            m³.
  Time needed to take effect: 16 hours, unless there are 
            special circumstances such as a  closed-in type of building, 
            which requires less time. If the weather is warm it is possible 
             to reduce this to a minimum of 6 hours. The period is to be 
            extended to at least 32 hours  if the temperature is below 5 deg. 
            Cent. 
  The strength and time as above are to be applied in 
            the case of:: bugs, lice, fleas, etc., with eggs, larves and 
            chrysalis. 
  For clothes moths: temperatures above 10 deg. 
            Cent.: 16 g per m3 and 24 hours to take effect. 
  For 
            flour-moths: same as for bugs . |

          | X  | 
          Fumigation of a building 
            | 
        
          |   | 
            | 
        
          |   1. | 
          Check that everybody has left 
            the building   | 
        
          |   | 
            | 
        
          | 2. | 
          Unpack the boxes of Zyklon. Make 
            the appropriate amount ready for each floor  | 
        
          |   | 
            | 
        
          |  3. | 
          Distribute the cans. One man to 
            go into the building and receive the cans which have  been 
            brought up by the work detachment and to distribute them. (Have them 
            put  next to the pads.)  | 
        
          |   | 
            | 
        
          |  4.  | 
          Dismiss the work 
          detachment.  | 
        
          |   | 
            | 
        
          | 5.  | 
          Post the guard. Fumigation chief 
            to instruct guard.  | 
        
          |   | 
            | 
        
          | 6.  | 
          Check that sealing and clearing 
            have been completed  | 
        
          |   | 
            | 
        
          | 7.  | 
          Put on gas masks.  | 
        
          |   | 
            | 
        
          | 8.  | 
          Open the cans and pour out their 
            contents. The contents are to be spread thinly so that  the 
            Zyklon can evaporate quickly and the necessary density of the gas 
            can be achieved  as soon as possible. This process is to start on 
            the top floor but the cellar is to be dealt  with before the 
            ground floor, should the cellar have no exit. Rooms which have been 
             dealt with should as far as possible not be re-entered. The 
            processing is to be done  slowly and calmly. The staircase 
            particularly should only be used slowly. The processing  may only 
            be interrupted in an emergency.  | 
        
          |   | 
            | 
        
          | 9.  | 
          The exit door to be locked, 
            sealed and its key handed over to the fumigation chief.   | 
        
          |   | 
            | 
        
          | 10.  | 
          On the door fix a warning sign 
            with the legend "Danger - Poison gas. Danger to life,  no 
            admittance". This warning sign is to be in several languages if 
            necessary, and in  any case it must be marked with at least one 
            death’s head, clearly visible.   | 
        
          |   | 
            | 
        
          | 11.  | 
          Gas masks, apparatus for 
            resuscitation and gas detectors are to be kept available at all 
             times. Every member of the fumigation squad must know where 
            these objects are located.  | 
        
          |   | 
            | 
        
          |  12. | 
          At least one member of the 
            fumigation squad must always remain near the building which is 
            being fumigated. The guard must be notified of his position.

          |  XI  | 
          Airing 
  The airing 
            is connected with the greatest danger for those participating and 
            others.  Therefore it must be carried out particularly carefully 
            and a gas mask should always  be worn. The airing should [take] 
            place according to the following principles: pure air  should 
            always be within reach in the shortest possible time and the gas 
            should flow  out to that side where it cannot endanger people who 
            are not participating. Should  the airing be difficult one 
            trained man should remain in front of the building in order  to 
            watch how the gas is blowing away.   | 
        
          |   | 
            | 
        
          | 1.  | 
          Take care to see that no 
            strangers remain in the vicinity of the building  | 
        
          |   | 
            | 
        
          | 2.  | 
          Post the guards in such a way 
            that they are not annoyed by the gas as it blows out, but can still 
            watch the entrances to the building  | 
        
          |   | 
            | 
        
          | 3.  | 
          Put on a gas mask.  | 
        
          |   | 
            | 
        
          | 4.   | 
          Enter building. Close door, but 
            do not lock it.   | 
        
          |   | 
            | 
        
          | 5.  | 
          First open the windows on that 
            side of the building where there is no wind. Air floor  by floor. 
            Start on the ground floor and after each floor take at least 10 
            minutes’ rest.  | 
        
          |   | 
            | 
        
          | 6.  | 
          The doors leading to the 
            corridor, connecting doors between rooms and windows must be 
             opened in each room  | 
        
          |   | 
            | 
        
          | 7.  | 
          Partitions and other methods 
            used to seal the room which cannot be replaced quickly  should 
            only be removed after most of the gas has blown away.   | 
        
          |   | 
            | 
        
          |  8. | 
          Care should be taken to see that 
            the heating system and water pipes do not freeze should there be 
            frost or danger of it.  | 
        
          |   | 
            | 
        
          |  9. | 
          Rooms with valuable contents, 
            such as clothing stores etc. may be locked again after the 
             windows have been opened.   | 
        
          |   | 
            | 
        
          |  10. | 
          Windows and doors which have 
            been opened should be fastened in such a way that they  cannot 
            slam.  | 
        
          |   | 
            | 
        
          |  11. | 
          Covers in chimneys may be 
            removed after the provisional release of the building.  | 
        
          |   | 
            | 
        
          |  12.  | 
          The airing should continue 
            for at least 20 hours.  | 
        
          |   | 
            | 
        
          |  13. | 
          The guard should remain near the 
            building during the whole of this time.  | 
        
          |   | 
            | 
        
          | XII  | 
          Provisional release A fumigated 
            room may be released provisionally as soon as the paper  strip of 
            the gas detector is of a lighter blue than the centre colour 
            pattern, when the doors  and windows are open. Only work 
            concerned with airing and clearing up may be done in  the rooms 
            which have been provisionally released. Under no circumstances may 
            anyone  rest or sleep in these rooms. The doors and windows must 
            be left open all the time.
