Many hams use the wording, "BREAK, BREAK, BREAK", (the word "break" repeated 3 times in a row). This is accepted practice on the hf bands where noise may be a problem but on repeaters, usually noise is not a problem, so using "plain" language such as "EMERGENCY", REPEATED 2 OR MORE TIMES can be used to announce that there is an emergency and the frequency is needed to relay vital information....if you hear an "Emergency" call during your conversation with another station....stop transmitting, acknowledge the station calling the emergency and let them have the frequency immediately! Don't delay them by saying something on the order of "Stand by breaker" and then carry on your conversation with your contact. Seconds wasted doing this may save a life!  Listen to them carefully and write down the details of their emergency. They will give you the details of the emergency. Then pause for a moment and wait before you go back to him.......many other hams who heard the emergency call may be responding ALL at the same time.

If someone "beats" you to getting back to him, let him take over. Do not break into the conversations UNLESS there is a need for a relay. Under certain situations due to distances involved with mobiles and repeaters, you may be able to hear a mobile BETTER than the repeater on the input frequency of the repeater. It is a good idea to monitor the input if possible if the station reporting the emergency is having trouble getting into the repeater. You may be closer to him than the repeater and can hear him better!

Whether or not the station reporting the emergency is a base station OR mobile, try to monitor the input of the repeater if there is difficulty in the emergency transmission.

IF YOU ARE REPORTING AN EMERGENCY:

When using VOICE,  use the international standard "MAYDAY" or universally understood "EMERGENCY" to announce traffic of life-or-death importance.

The procedure should be:

1.Select the repeater frequency.
2. Wait for a space between transmissions if the repeater is busy.
3. Key your mic and state..."Emergency, Emergency, Emergency" unkey.
4. Wait for a response from the repeater users. If you get no response, try another repeater.

When you do make contact, state your call sign and give as many details as to the emergency as possible. Don't panic, speak slowly and clearly so the details will be understood the first time! Always give details as exact and specific. Give the details of the exact LOCATION of the emergency using enough description of the location so it can be found easily by first responders. Don't say....on highway 60 and leave it at that. The emergency vehicles need exact locations if at all possible. Remember, seconds or minutes saved equal lives in many cases!

Give number of "victims" if possible. Is there is fire involved, downed power lines, immediate road blockage due to wreckage creating further dangers? DETAILS, DETAILS, DETAILS.

The person on the other end of your transmission is most likely copying the info to paper so he can relay it to the appropriate authorities. Help him help you!
