    The water is more effective if applied through a jet with. force behind it. A simple appliance for household use is the Stirrup Hand Pump (Home Office Specification) for use with an ordinary bucket. It has 30 feet of hose and a special nozzle which can be adjusted to deliver a jet for dealing with fires or a spray for use on an incendiary bomb (see page 27). Because of its two uses, it is more generally useful than the Redhill sand container. But remember that water must mot be thrown on an incendiary bomb except as spray. PUBLIC WARNING SIGNALS» The Air Raid Warning may be given by hooters or sirens, and will be either a continuous, fluctuating note, or a succession of blasts with silent intervals between. The whole signal will last two minutes. (In addition, the police and wardens may blow sharp blasts on their whistles.) _ The Raiders Passed Signal will be a continuous signal at a steady pitch, also lasting two minutes. The Aix Raid Warning means that raiders may reach your district in about five minutes. This does not necessarily mean that they will drop bombs near you: they may go farther on. So that, though you should take all precautions, you are not necessarily in danger. The Raiders Passed Signal means that the raiders have left the district. But there may be gas about, so take care when coming out of your refuge-room. Street Signals A local Gas Warning will be given when gas has been Seen Wardens will give it by means of a hand rattle in the streets affected. The ringing of handbells, after the Raiders Passed Signal, will mean — either that no gas is present or that there is no further danger from gas.
