If possible, the stuffing of straw palliasses should be changed. The old stuffing may not however, be burnt, but may be re-used after it has been aired for a further period. Should the chimneys have been covered from above, these coverings must be removed carefully, since otherwise there is a danger that the fires in the stoves and hearths will not have sufficient draught, which may cause carbon monoxide poisoning. After the final release has been made, two copies of a fumigation report are to be filled in, in the prescribed manner. Under no circumstances less than 21 hours after airing was started.
All items removed for beating are to be taken back into the room.
Doors and windows to be closed for one hour. In rooms with heating facilities, a temperature of at least 15 degrees Centigrade must be produced. Should this not be the case, airing must continue and the check for gas repeated after a few hours. The check for gas must be made in each room of buildings which are again to be used as sleeping accommodation as soon as possible. Under no circumstances may anyone sleep in a room which has been fumigated in the night following the fumigation.
