Video 15, Communication in Catastrophes. 00:00:00
This video belongs to didactic unit number 6, Communications. 00:00:08
With it, we'll be working on learning outcome number 4, 00:00:13
being able to handle communications. 00:00:16
Analyzing the way the elements of an autonomous communication network work. 00:00:20
One of the possible damages caused by a catastrophe 00:00:26
is the disruption of the existing communication networks. 00:00:28
As an introduction, we could start a debate with the students about the results of that situation, asking, 00:00:32
how can we establish a communication during a catastrophe response? 00:00:40
During a catastrophe, the habitual communication networks can get disrupted. 00:00:48
In the event of a hurricane, a flood, or an earthquake, for example, 00:00:53
it's necessary to establish alternative emergency communication networks. 00:00:58
The highest response commander will decide which system will be used, and the logistic support team will prepare the necessary equipment to ensure communications inside the response area and with the coordination center. 00:01:02
We should also have other alternatives in case the chosen system fails, like satellite telephony. 00:01:16
There could be autonomous networks that are temporarily installed in the affected areas until the habitual networks are reestablished. 00:01:22
We could also resort to REMER, a volunteer organization of radio amateurs who offer their services to civil protection if the situation demands it. 00:01:31
An autonomous communication network will be necessary when there is an unavailable network because of a catastrophe. 00:01:40
This type of network has some basic elements. 00:01:52
A base station with a transmitter, an antennae, repeaters, portable equipment or walkie-talkies, and satellite telephony. 00:01:55
These equipments can be installed on the ground or on a vehicle, which will also serve as the advanced command post, like the ones in the images. 00:02:02
Emergency organizations, like the UME, have these equipments. 00:02:11
The energy they need is supplied by generators, solar panels or the batteries of the vehicle. 00:02:15
It is essential to know how every element of the network works, which we can learn in specific training courses. 00:02:20
We also have to check if they work and think of alternative actions in case they fail. 00:02:27
they fail. It's important to remember that walkie talkies will be our usual communication tool. 00:02:31
We must have a clear knowledge of what they are like and how they work. 00:02:40
The standard equipment will have at least these components. An on-off switch which can be 00:02:44
integrated in the volume control knob, a microphone or speaker, a channel selector knob, a push to talk 00:02:50
or PTT button and an antennae. It's compulsory to check the state of the communication equipment 00:02:57
before its interventions and carry out basic maintenance like battery charging, cleaning, etc. 00:03:04
When using walkie-talkies we might come across some problems like the equipment not being 00:03:15
charged, channels not being properly tuned in, and interferences, background noise, no coverage, etc. 00:03:20
It's important to have solutions and alternatives to offer if we come across these problems, 00:03:30
for instance, checking the battery charge level and always charging them after they use, 00:03:36
finding and agreeing on free channels to avoid interferences, avoiding crowds and when to avoid noise, 00:03:42
placing one or several repeaters in low-coverage areas like mountains and tunnels. 00:03:49
As an activity, we suggest some practice with the walkie-talkies we have in the workshop. 00:03:55
They'll find the different components in the usual manual and check they work. 00:04:04
To do this, we'll follow a protocol. Is it charged? Does the speaker work? 00:04:09
Does the microphone work? Is there a signal? Am I using the right channel? 00:04:14
If we have a station, we'll also check if it works. 00:04:19
By establishing communication with the portable equipment through a determined channel, 00:04:23
They'll also define situations in which they might find difficulties with their use and decide how to solve them. 00:04:27
It's important to remember that to ensure communication, all the participants will communicate in the same way. 00:04:33
They'll follow the same procedure, which consists of a number of codes, code names, norms and ordinary and extraordinary ways of using them. 00:04:43
Every organization has their own procedure, which all its members must know. 00:04:52
must know, but there are some general norms that are included in all the 00:04:57
procedures. Listening before speaking, being brief, speaking clearly, using 00:05:01
usted, using established codes, etc. We must also remember that using codes in 00:05:07
radio telephony communication is essential, so we must be proficient at 00:05:16
using them. The most well-known is definitely the ICAO code, but others can 00:05:21
also be used, like the Q or the 10 codes, which are sometimes used for specific standard orders. 00:05:27
Our codes are used to indicate the quality of the transmission, and there are codes for medical 00:05:34
conditions, which are specific to every organization. We must know them and use them skillfully. 00:05:39
In order to establish communication, it's also very important to know our interlocutors, 00:05:47
who won't use their own names, but their code names. 00:05:53
Every organization uses its own codenames, which must also be known by all its members. 00:05:56
As an activity, we suggest analyzing and comparing the SAMR and the Red Cross communication procedures 00:06:07
to find their similarities and their differences. 00:06:13
Here are the links to both procedures. 00:06:16
In a catastrophe, many different organizations might be involved. 00:06:22
A compatible system and a common communication procedure must be established. 00:06:26
The commander usually divides the incident area and every team is assigned to one of these areas to perform their tasks. 00:06:31
As an activity, we suggest continuing with the activity in the previous video, the settlement in Madrid after the earthquake, 00:06:40
to do some practice on communication with the same groups. 00:06:47
We must establish a radio communication procedure since an autonomous radio station is available. 00:06:53
We'll describe the communication needs of every group. 00:07:00
we'll agree on channels and establish a communication procedure based on what 00:07:03
we've previously seen. We'll carry out a communication drill in different 00:07:09
situations like a damage in the latrines, disturbances in the food distribution 00:07:14
zone or any other situation. We'll set up a coordination center composed of one 00:07:20
member of each team. With the Google Maps app we'll divide the area in zones and 00:07:27
then we can also create a code for every location in the settlement. 00:07:36
