This student handbook goes over the types of radio traffic. When learning how to use the radio, it is important to know that there are three types of radio traffic. These include: Routine traffic - the regular, daily radio traffic one would hear on the mine radio including basic emergencies such as an injured employee, but whose injuries are not life threatening. Emergency traffic - radio traffic about an emergency situation (e.g., a miner with a fractured arm or the loss of ventilation on a working section). In these situations, a miner would call out that they have emergency radio traffic. Then the dispatcher or communications person would clear the airways for this person to state the problem. Mayday traffic - describes radio traffic when a major mine emergency occurs (e.g., explosion, fire) or someone is in danger of death (e.g., heart attack, pinned by machinery or roof fall). The term "Mayday" is repeated three times, "Mayday, Mayday, Mayday". In this case the dispatcher should respond by asking all other traffic to cease, except for the Mayday traffic. The handbook is presented in two sections: routine traffic (or basic use) emergency and Mayday traffic. Note: Your mine may have different designated terms for each type of radio traffic; if this is the case, then you should use those designated terms. This Student Handbook is intended for use in a group training setting or for individual trainees and should be used in conjunction with the PowerPoint presentation, "Radio 101: every day and emergency radio use" (CD-ROM) and the Radio 101: Instructor's Guide (publication).
