(cont.)
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. |

VI |
Equipment
Each
member must at all times carry with him:
1. His own gas
mask. 2. At least 2 special filter inserts against Zyklon prussic
acid. 3. The leaflet "First aid for prussic acid poisoning."
4. Work order. 5. Authorization certificate.
Each
disinfestation squad must at all times carry:
1. At least 3
special inserts as extra stock. 2. 1 gas detector. 3. 1
instrument for injecting Lobelin. 4. Lobelin 0.01 g. ampules
5. Cardiazol, Veriazol tablets. 6. 1 lever or pickhammer for
opening the cans of Zyklon. 7. Warning signs as per regulation.

Planning fumigations
|
1. |
Can the fumigation be carried
out at all?
a) Type of building and situation. b)
Condition of roof. c) Condition of windows. d) Presence of
heating shafts, air shafts, breaks in the walls, etc. |
|
|
2. |
Determine the kind of vermin to
be exterminated. |
|
|
3. |
Calculate the space (do not rely
on drawings, but take measurements yourself. Take only outside
measurements, include walls). |
|
|
4. |
Prepare
personnel.
(Remove domestic animals, plants, food and drink,
undeveloped photographic plates, and gas mask
filters.) |
|
|
5. |
Find which opening will be
particularly difficult to seal.
(Air shafts, drains, large
openings which have been boarded up, roofs.) |
|
|
6. |
Settle necessary safety
measures.
(Guarding, work detachment for
sealing.) |
|
|
7. |
Fix the date for the fumigation
and the time for clearing the building. |
|
|
8. |
If necessary, arrange safety
measures for the neighborhood in good time. |
|
|
9. |
Notify authorities. |
|
|
VIII |
Preparation for fumigation
|
|
|
1. |
Seal. |
|
|
2. |
Open all doors, closets,
drawers, etc. |
|
|
3. |
Pull bedding apart. |
|
|
4. |
Remove all liquids (remains of
coffee, washing water etc.) |
|
|
5. |
Remove all food |
|
|
6. |
Remove all plants and domestic
animals (aquaria etc.) |
|
|
7. |
Remove all undeveloped
photographic plates and films. |
|
|
8. |
Remove adhesive plaster, all
medical supplies, whether open or in paper bags (particularly
[char]coal). |
|
|
9. |
Remove all gas mask
filters. |
|
|
10. |
Prepare for check on results.
|
|
|
11. |
Clear out personnel.
|
|
|
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 . |

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.
