Part one of two

Objectives:

This two part training material on Operations and Logistics will help you understand and deal with some of the operating and logistical issues that arise during emergency relief and communication operations.

Information:

Choosing Phone Net Frequencies

Unlike commercial and public safety radio users, Amateurs have a vast amount of radio spectrum to use in meeting the needs of an emergency. Most local and regional emergency communications takes place on 2 meter or 70 centimeter FM, or on 40, 60, or 80 meter SSB/CW. The choice made is based on the locations to be covered, the availability of repeaters, distance, terrain, and band conditions.

VHF and UHF FM are preferred for most local operations because of the equipment is common, portable, has a clear voice quality and the coverage is extended by repeater stations. VHF and UHF communication range is determined by terrain, antenna height, and the availability of repeaters.

For larger areas or in areas without repeaters, HF SSB may be needed.  Most local emergency communications operation is on the 40 or 80-meter bands. For long-haul communication needs and international operations, 15 or 20-meter nets may be the best option.

Many emergency communications groups will have pre-selected a number of frequencies for specific purposes. The complete list of these frequencies should be in your jump kit, and pre-programmed into your radios.

Know Your Resources In Advance

Become familiar with the coverage and features of each permanent repeater and digital message system in your area, and pre-program your radios with the frequencies, offsets, and CTCSS tones. Ask your EC or AEC which repeaters are used for emergency communication in your area. Will they be available for exclusive emergency communications use, or must they be shared with other users?  Information to find out include:

Network Coverage Concerns

Most emergency communications managers rely on simplex operation when planning their VHF or UHF FM nets for one reason -- repeaters often do not survive disasters or are overwhelmed with the amount of traffic. Repeaters that do survive and are usable are considered a bonus. Since simplex range is limited by terrain, output power, antenna gain and height, operation over a wide area can be a challenge. Almost any structure or hill can block signals to some degree.

To avoid last minute surprises, your group should pre-test all known fixed locations in your area for coverage. For instance, if you are serving the Red Cross, test simplex coverage from each official shelter to the Red Cross office and the city's EOC or other key locations, and mobile coverage in the same areas. If needed, there are several ways to improve simplex range:

In a fast moving situation with poor simplex coverage and no repeater, it can be helpful to place a mobile station on a hilltop or office building where they can communicate with, and relay for, any station in the net. A mobile relay station can also allow communications to follow a moving event, such a wildfire or flash flood. That station becomes, in effect, a "human repeater". Although an expedient "work-around", this is a slow and cumbersome process that can reduce net efficiency by more than half. A modern aid to this kind of operation is the "simplex repeater". This device automatically records a transmission, and immediately re-transmits it on the same frequency. Remember that FCC rules do not allow unattended operation of simplex repeaters, and that you must manually identify it.

A better solution is a portable duplex repeater that can be quickly deployed at a high point in the desired coverage area. The coverage of this repeater does not have to be as good as a permanent repeater -- it just has to reach and hear the stations in your net. Portable repeaters have been used successfully from the back seat of a car, using a mobile antenna, and parked on a ridge or even the top floor of a parking garage. Portable masts and trailer-mounted towers have also been used successfully.

If all stations in the net have dual-band radios or scanners, a strategically located mobile radio may be operated in "cross-band repeater" mode. If you use your dual-band mobile in this manner for an extended period, use the low or medium power setting to avoid overheating and damaging your radio. Consider using a fan to further reduce the likelihood that your radio will be damaged from overheating.

For a permanent repeater to be useful in a disaster, it must have emergency power, and be in a location and of such construction that it can survive the disaster. Agreements with repeater owners should be in place to allow emergency operations to the exclusion of regular users.

Frequency and Net Resource Management

While we may have a large amount of frequency resources, in actual practice our choices are limited to the available operators and their equipment. Net managers may occasionally need to "shift" resources to meet changing needs. In the early stages of an emergency, the tactical nets may require more operators, but in later stages, the health and welfare traffic might increase.

In addition to the main net frequency, each net should have several alternate frequencies available. These should include one or more "back up" frequencies for use in the event of interference, and one or two frequencies to be used to pass traffic "off net".

Message Relays

When one station cannot hear another, a third station may have to "relay" the messages. Although this is a slow and cumbersome process, it is often the only way to reach certain stations. If relays must be used, move the stations involved off the main net frequency to avoid tying up the channel for an extended period.

Radio Room Security

To protect your equipment and the messages you handle, and prevent unnecessary distractions, it is best to allow only the operators who are on duty to be in the room. Avoid leaving the radio room and equipment unattended and accessible. It is never a good idea to allow members of the press to be in the room without specific permission from the served agency.

Record Keeping

Most served agencies will expect you to keep records of your operations. These records will certainly include original copies of any messages sent, station logs, memos, and official correspondence. Some may even require you to keep "scratch" notes and informal logs. Depending on agency policy, you may be required to keep these records in your own possession for a time, or to turn some or all records over to the agency at the end of operations. In some agencies, your station records are permanent and important legal documents, and must be treated as such. It is important to know your served agency's policy on record keeping in advance so that you can comply from the very beginning of operations.

Your station operating logs should probably contain the following information:

Every individual message or note should be labeled with a time and date. In the case of scratch notes, place dates and times next to each note on a sheet, so that information can be used later to determine a course of events.

If you expect to operate from the location for more than a day or two, establish a message filing system so that you can retrieve the messages as needed. A "portable office" type file box, expanding file, or any other suitable container can be used to organize and file the messages. This is also an efficient way to allow another operator to pick up where you left off, even if they arrive after you leave. Effective record keeping allows them to come up to speed quickly.

Part two

Dealing With Stress and Egos

Any unusual situation can create personal stress – disasters create incredible amounts of it. Most people are not used to working under extreme stress for long periods, and do not know how to handle it. They can become disoriented, confused, unable to make good decisions or any decisions at all, lose their tempers, and behave in ways they never would any other time. Nervous breakdowns are common among those who get overwhelmed and have not learned to manage stress and stress-causing situations.

Especially in the early hours of a disaster, the tendency is to regard every situation or need as an “emergency,” requiring an immediate response. You might get a barrage of requests for action.  You might not have the extra seconds it requires to fully consider the options, and to prioritize your actions. The result is an overload of responsibility, which can lead to unmanageable levels of stress.

While you cannot eliminate disaster-related stress, you can certainly take steps to reduce or control it. Here are some tips to help you manage the situation to avoid creating, and deal with, excessive stress and stressful situations:

Some within the emergency response community have “big egos”, and still others with a need to be in full control at all times. Both personality types can be problematic anytime, but far worse under stress. Take time now to consider how you will respond to the challenges they present. If your automatic response to certain behaviors is anger, make a conscious decision to come up with a different and more positive response strategy. Depending on the official position of the “problem” person, you might:

Long Term Operations

As soon as it becomes clear that the situation is not going to return to normal for a while, you and your group should make plans for extended emergency communications operations. Hopefully, your emergency communications group and served agency have prepared contingency plans for this, and all you will have to do is put them into action. If not, here are some potential needs to consider:

Battery Management

If you are operating on battery power, you will eventually need to recharge your batteries. If you are using slow-charging batteries, you may need to have enough on-hand to last the entire length of the operation. If your batteries can be charged quickly, some means must be provided for doing so. Some chargers can be powered from a vehicle’s 12-volt system, and are a good choice for emergency communications. If no local means of charging is available, your logistics team may need to shuttle batteries back and forth between your position and a location with power and chargers.

Generator and Power Safety

Take some care in the placement of generators so that they will not be a problem for others. Engine noise can make it difficult for shelter residents and volunteers to get much needed rest, and for anyone trying to do their job. Exhaust fumes should not be allowed to enter the building or nearby tents or vehicles. A position “down-wind” of any occupied location is best. Even when vehicles are not included, internal combustion engines are still the number one cause of carbon monoxide poisoning in the United States. Propane powered engines produce as much or more CO as gasoline or diesel engines.

Earth grounding of portable or vehicle-mounted AC generators is not required as long as only plug and cord connected equipment is used, and the generator meets National Electrical Code (NEC) standards listed in Article 250-6. The main exception is for generators that will be connected, even temporarily, to a building’s permanent electrical system..

Ground Fault Interrupters (GFIs) add a further degree of safety when working with generators and portable power systems. GFIs detect any difference between the currents flowing on the hot and neutral conductors, and opens the circuit. Also, be sure to test any GFI device to be used with or near HF radios to be sure that the GFI will function properly while the radio is transmitting.

AC extension cords used to connect to generators or other power sources should be rated for the actual load. Consider radios, lights, chargers, and other accessories when calculating the total load. Most extension cords are rated only for their actual length, and cannot be strung together to make a longer cord without “de-rating” the cord’s capacity. For example, a typical 16ga, 50’ orange “hardware store” cord is rated for 10 amps. When two are used to run 100’, the rating drops to only 7 amps. Choose a single length of cord rated for the load and the entire distance you must run it. If this is not possible, you can also run two or more parallel cords to the generator in order to reduce the load on any single cord.

While some groups have use “Romex ™” type wire for long extension cords, this is actually a violation of the National Electrical Code, and a dangerous practice. Repeated bending, rolling, and abrasion can cause the solid copper conductors and insulation to break, resulting in a fire and electrocution hazard. Use only flexible insulated extension cords that are UL rated for temporary, portable use.

Equipment – Leaving Yours Behind?

You are exhausted, and ready to head for home, but the emergency communications operation is far from over. You brought along a complete station, and when you leave, the next operator is not nearly as well equipped. Should you leave your equipment behind for the next operator?

You have several options here – and they are all yours to choose from. No one can, or should, tell you to leave your equipment behind. If you feel comfortable that someone you know and trust will look after your gear, you may choose to leave some or all of it behind. If you do, be sure every piece is marked with at least your name and call sign. Do not leave behind anything the next operator does not truly need. Also, remember that even if you leave the equipment in the possession of someone you know, you still have the ultimate responsibility for its operation and safety. Emergency stations are difficult places to control and monitor. If your equipment is stolen, lost, or damaged, you should not hold anyone responsible but yourself. Conversely, if someone leaves their equipment in your care, treat and protect it better than you would your own, and be sure it is returned safely to its owner.

Accepting Specialized Assignments

In the world of modern emergency communications, you may be asked to handle other assignments for the served agency that may or may not include communicating. At one time, most emergency communications groups had strict policies against doing other tasks, and this is still true of some. In the days when radios were difficult to operate under field conditions and required constant attention, this was important. The other common reason given is that you have volunteered to be a communicator, not a “bed pan changer”. It is true that some agency’s staff will abuse the situation when they are short of help, but if both the agency’s staff and emergency communications group are clear about any limits beforehand, the problem should not arise.

Today, most emergency communications groups will permit their members to be cross-trained for, and perform, a variety of served-agency skills that also include communicating. Examples are SKYWARN weather spotting, Red Cross damage assessment, and many logistics jobs. If your group still has a “communication only” policy, are you really meeting your agency’s needs? Is it necessary to have a damage assessment person AND a communicator to do that job? What would happen to your agency if each driver also had to bring along a dedicated radio operator? Can one person do both jobs?

Review:

Simplex operation is often preferred over repeaters because repeaters may fail in a disaster situation. Frequencies and operators are a resource that should be managed for maximum efficiency and effectiveness. Record keeping is essential to an effective emergency communications operation. It allows messages to be tracked, and preserves continuity when personnel change. Demanding situations like disasters can breed disagreements, especially when strong egos and short-fused tempers are introduced. Take steps to reduce the level of stress on yourself, and do not respond in kind to an angry person. When an operation looks like it will be an extended one, begin immediately to prepare for the additional people and resources necessary to sustain the operation. Arrange to charge batteries as needed. Use generators and power distribution equipment safely. Leaving your equipment behind is a choice only you can make. Think about this well in advance to be sure other arrangements are made before you leave with all your equipment. Modern emergency communications groups often accept other agency tasks beyond just communications.
