(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. |

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.

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. |

Prepare for check on
results. |
| |
|
| 11. |
Clear out personnel.
|
| |
|

| |
|
| 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. |
