It is <br />important that you limit phone call <br />'to emergencies only. Do not call <br />"9-1-1" or the police for <br />confirmation of an earthquake. <br />Listen to your local radio or <br />television station for information. <br />Blocking <br />In cases of extreme congestion of <br />the telephone network, Pacific Bel <br />and/or long distance carriers may <br />institute blocking. Blocking <br />prevents overloading the system b, <br />diverting some cafls to recordings, <br />allowing other calls to complete. <br />If you need to place an emergency <br />call: <br />1. Make sure receivers of all <br />extension phones are on the switc <br />hook. <br />2. Stay on the line. You may not <br />hear dial tone immediately: the <br />delay could be as long as a minutf <br />or more. <br />3. Do not repeatedly depress the <br />switch hook, as this will further <br />delay your call. <br />4. If you receive a "fast busy" or <br />"all circuits are busy" recording, <br />hang up and try again. <br />5. If physical damage occurs in ou <br />equipment or facilities or your <br />wiring, it may not be possible to <br />complete your call. <br />Out -of -Area Contact <br />It may be easier to call out of the <br />disaster area during emergencies <br />See page B9 for procedures on <br />establishing an out of area contac <br />Once contact is made, have this <br />person relay messages to your <br />other friends and relatives outsidf <br />the disaster area to reduce cailinc <br />
