Public Information No 2 deals with ‘Your Gas Mask’ and ‘Masking your Windows’.
‘Your Gas Mask’
The mask consisted of a metal container filled with a chemical which absorbs the gas and a rubber face piece with a non-inflammable transparent window. People were advised to store it properly in the box in which it was issued or any other air tight box.
The leaflet contained instructions on how to put the mask on pointing out that this may need to be done in a hurry. Instructions were given on how to prevent the widow steaming up and how to take the mask off and putting it away correctly for storage.
‘Masking Your Window’
In War the leaflet noted that one of the protections against air attack would be the “black-out”. On hostilities being declared all external and street lights would be extinguished so as not to give hostile aircraft any indication to their whereabouts. This could only be effective if households ensured no light could be seen from their homes.
Close fitting blinds which where of a thick dark coloured material were the most effective way of shutting in the light. If a household did not have these alternatives were fixing up black or thick brown paper mounted on battens or thick curtains if they covered all round the window. Skylights could be made obscure by painting with dark distemper paint or pasting them over with dark paper.
Households were also reminded not to let light show when the front or back door was open.
