00:00:04
starting to study the topic of
00:00:06
personal and collective protective equipment, let's
00:00:08
consider the basic concepts of
00:00:10
personal protective equipment - these are
00:00:12
technical means that are
00:00:14
used to prevent or
00:00:16
reduce a person's exposure to
00:00:17
harmful or environmentally hazardous facts;
00:00:20
respirators are a means that are
00:00:22
designed to protect the respiratory system
00:00:24
from aerosols of dust and smoke, fog or
00:00:28
harmful including carbon monoxide,
00:00:30
a gas mask is a device for protecting the
00:00:33
respiratory organs of a person's eyes and face from
00:00:36
toxic and radioactive substances,
00:00:37
bacterial means of
00:00:40
collective protection,
00:00:41
this is a structure or special
00:00:43
equipment for the group protection of people, a
00:00:45
shelter, these are special structures
00:00:48
designed to protect people from the
00:00:50
damaging factors of a nuclear explosion of
00:00:52
toxic substances and bacterial
00:00:54
agents as well as from high temperatures and
00:00:57
harmful gases formed during a fire, we will
00:00:59
consider in more detail and the
00:01:01
personal protective equipment
00:01:03
most widely used are
00:01:04
filter gas masks GP-5 and db7
00:01:07
gas masks GP-5 consists of a filter
00:01:10
absorbing box and the front part of a
00:01:12
helmet-mask; it does not have connecting
00:01:14
tubes In addition, the kit includes a
00:01:16
bag for a gas mask and does not fog up and
00:01:19
films or a special pencil. The
00:01:21
GP-5 gas masks kit includes a helmet; a
00:01:24
mask with a membrane box for an
00:01:25
intercom; to select the
00:01:28
required helmet size, you need to
00:01:29
measure your head along a closed line
00:01:31
passing through the top of the head; cheeks and
00:01:34
chin; measurements are rounded up to 5
00:01:37
millimeters with a measurement of up to
00:01:40
sixty-three centimeters and take
00:01:42
zero height from sixty-three and a
00:01:45
half to sixty-five and a
00:01:46
half centimeters 1 height from 66 to
00:01:50
sixty-eight centimeters 2 from
00:01:53
sixty-eight and a half to 70 and a
00:01:55
half centimeters 3 here is 71
00:01:58
centimeters or more 4 height
00:02:00
before use, the gas mask must be
00:02:02
checked for proper sealing,
00:02:04
inspect the front part,
00:02:07
make sure that the height of the helmet-mask
00:02:09
meets the requirements,
00:02:10
then determine the integrity, paying
00:02:13
attention to the glasses of the assembly,
00:02:15
after that check the valve box,
00:02:18
the condition of the valves, they should not be
00:02:21
ship-specific and clogged or torn on the
00:02:24
filter absorber boxes there
00:02:26
should be no dents rust punctures and there should be no
00:02:29
damage in the neck I also draw attention
00:02:32
to the fact that
00:02:34
grains are not poured into the box absorber gas mask
00:02:37
is assembled in this way in the left hand take the helmet
00:02:39
mask by the valve box with the right hand
00:02:41
screw the filter
00:02:43
absorber box onto the bathroom screw until it stops
00:02:45
necks pipe valves boxes
00:02:47
helmet masks before putting on the front part of the gas mask
00:02:50
must be wiped
00:02:51
outside and inside with a clean cloth slightly
00:02:54
moistened with water and the exhalation valves must be blown out.
00:03:07
the bag is down, the filtering
00:03:09
absorption box is on top, the helmet is a mask
00:03:12
that is not bent, only slightly
00:03:14
supports the head and side parts and
00:03:16
so as to protect the glasses of the glasses of its assembly,
00:03:19
wears a gas mask of the bag, which is put on
00:03:21
as follows: the
00:03:22
shoulder strap is thrown over the right
00:03:24
shoulder, the
00:03:25
bag itself is on the left side with the valve away from
00:03:27
you, the gas mask can be the
00:03:30
traveling position is ready because its traveling position is a
00:03:34
position when there is no threat of infection with
00:03:36
toxic substances
00:03:37
emergency chemically hazardous substances
00:03:40
radioactive dust bacterial
00:03:42
means the bag is on the left side when walking
00:03:45
it can be moved back a little
00:03:47
so as not to interfere with the movement of the arms up
00:03:49
the bag should be at waist level the valve is
00:03:52
caught in position to prepare, the gas mask
00:03:55
is transferred already in the event of a threat of infection after
00:03:57
information on radio and television or on
00:03:59
command, the gas mask is ready in this case,
00:04:03
the bag must be secured with a waist band,
00:04:05
slightly move forward to overtake the bug so
00:04:08
that you can quickly
00:04:09
use the gas mask in a combat
00:04:12
position, the front part is put on, does this
00:04:16
on command gas on other times in Paris and
00:04:19
also independently when detecting
00:04:21
signs of one or another,
00:04:23
even a gas mask is considered to be put on
00:04:26
correctly think about the fists of the front
00:04:28
part is against the duos
00:04:29
helmet-mask fits tightly to the face it is
00:04:32
necessary to exhale strongly before
00:04:35
opening the eyes and resuming breathing
00:04:37
after putting on the gas mask this
00:04:40
is explained by the fact that it is necessary to remove
00:04:42
contaminated air from under the helmet-mask, if it
00:04:44
got there at the moment on the sofa with a
00:04:46
gas mask on, you should breathe
00:04:48
deeply and evenly, you
00:04:50
should not make sudden movements, if there is a
00:04:52
need to run, then start
00:04:55
jogging, gradually increase
00:04:58
and remove the gas mask on command,
00:05:00
the gas mask is not for To do this, you need to lift the
00:05:03
main headgear with one hand, grab the
00:05:05
valve box with the other, slightly pull the
00:05:07
member of the mask down and move forward up,
00:05:10
remove it, put on the headgear, turn
00:05:12
out the helmet Moscow, thoroughly
00:05:14
wipe
00:05:15
and put the bag on your own without a
00:05:18
command, the gas mask can be removed only
00:05:20
when it becomes reliably known
00:05:22
that the danger of destruction has passed
00:05:24
civilian gas mask GP-7 is
00:05:26
one of the latest and most advanced
00:05:28
models; it reliably protects against
00:05:30
poisonous and many highly
00:05:32
toxic substances, radioactive and
00:05:35
bacterial agents; it consists of a
00:05:37
filter-absorbing GP-7 box to the
00:05:40
front part of the MGP; their films do not fog up;
00:05:43
6 pieces of insulating cuffs; two
00:05:45
pieces of protective knitted covers and
00:05:48
bags, its weight included without a bag is about
00:05:50
900 grams, the filter absorbing
00:05:53
box is 250 grams, the front part is 600
00:05:55
grams, but the filter absorbing box
00:05:58
is put on a knitted cover that
00:06:00
protects it from dirt, snow, moisture,
00:06:02
ground dust, the
00:06:03
principle of the protective action of gas masks
00:06:05
GP-7 and the purpose of its main parts
00:06:08
the same as GP-5, however, GP-7
00:06:12
compared to GP-5 has a number of significant
00:06:14
advantages
00:06:15
both in operational and
00:06:17
physiological indicators, due to
00:06:20
this it can be used by people over
00:06:22
60 years of age,
00:06:23
as well as people with pulmonary and
00:06:25
cardiovascular diseases
00:06:27
the presence of a membrane intercom in the gas
00:06:29
mask ensures a clear
00:06:31
understanding of the transmitted speech;
00:06:34
selection of the front part of the required
00:06:35
standard size GP-7 is carried out
00:06:38
based on the results of measuring the
00:06:40
horizontal and
00:06:42
vertical circumference of the head with a soft centimeter tape to protect the
00:06:44
respiratory system from harmful gases, vapors and
00:06:47
dust aerosols using a respirator,
00:06:49
depending on the purpose. there are
00:06:52
anti-dust gas masks
00:06:54
and gas dust protection depending on the
00:06:57
service life, respirators are disposable and
00:07:00
reusable
00:07:01
when they are not gas masks not a
00:07:03
respirator, you can use the
00:07:05
simplest means of protection - a
00:07:06
cotton-gauze bandage, it quite
00:07:09
reliably protects the respiratory system from
00:07:11
radioactive dust and harmful aerosols and
00:07:13
bacterial agents
00:07:15
cotton-gauze the bandage is made
00:07:17
from a piece of Morse code measuring 100 by 50
00:07:20
centimeters, the middle part of which is placed in an
00:07:22
even layer of cotton wool about 2 cm thick; the
00:07:25
ends of the gauze free of cotton along the entire
00:07:28
length of the piece on both sides are wrapped;
00:07:30
I close the cotton wool; the ends of the gauze are about
00:07:34
35 centimeters in size on both sides;
00:07:39
calls a cotton-gauze bandage is applied
00:07:42
on the face so that the lower edge covers the
00:07:44
bottom of the chin and the upper reaches the
00:07:47
eye sockets, while the
00:07:51
mouth and nose should be well covered, the cut ends are tied, the
00:07:56
lower one is tied on the crown of the head, the upper one is
00:07:59
back and in case of radiation chemical and
00:08:02
bacteriological contamination, accidents and
00:08:04
natural disasters with emission of
00:08:06
toxic substances, it is necessary to protect
00:08:08
not only the respiratory organs,
00:08:10
but also the entire body, the human skin, you see a
00:08:13
light protective suit L-1 general
00:08:15
wax protective kit music, it
00:08:18
provides protection of the skin from toxic
00:08:20
substances and radioactive substances and
00:08:22
bacteriological agents, if
00:08:24
necessary, you can use the
00:08:26
simplest available means of protection
00:08:29
leather, this can be industrial
00:08:31
clothing, jackets, trousers, overalls, it is better from
00:08:34
tarpaulin, fire-retardant and rubberized
00:08:36
fabric,
00:08:37
as well as items of household clothing,
00:08:39
raincoats and capes and winter things, they can protect
00:08:42
not only and even radioactive substances, but
00:08:43
also from drops and bars of many from
00:08:45
substances to protect the legs better
00:08:48
Rubber boots and galoshes are all that are suitable; they are capable of
00:08:51
not allowing droplets of liquid
00:08:53
toxic substances to pass through for up to 6 hours. The
00:08:55
hands will be protected by mittens made of
00:08:57
rubber tarpaulin or leather gloves. The head
00:08:59
can be tied with a thick scarf or
00:09:01
put on a hat with earflaps. In addition to individual
00:09:04
cuts, the shield can be collective means of
00:09:05
protecting the population, for example, shelters, shelters,
00:09:09
this is engineering and technical. a structure
00:09:11
that provides protection; we shelter people in it
00:09:14
from all damaging factors of
00:09:15
a nuclear explosion,
00:09:16
as well as from toxic substances and
00:09:19
bacterial agents, high temperatures
00:09:22
and harmful gases; in the fire zone
00:09:24
at the location of the shelter, shelters can be
00:09:27
built into the underground parts of the building and
00:09:29

and the clean mode is turned on ventilation for
00:10:48
normal conditions, a
00:10:50
certain temperature
00:10:51
and humidity are maintained inside the shelter; if people are to stay in the shelter for a
00:10:54
long time,
00:10:56
conditions for rest and sleep are created;
00:10:58
if
00:11:00
poisonous or
00:11:02
toxic substances are detected infiltrating the air, they are
00:11:03
covered and immediately put on
00:11:05
respiratory protection
00:11:07
and the shelter is switched to filter mode
00:11:09
ventilation, these measures are ensured by a
00:11:12
radiation chemical observation post
00:11:13
in the event of fires occurring near the shelter
00:11:17
or the formation of dangerous concentrations of
00:11:19
radiation and toxic substances, the
00:11:20
protective structure is switched to
00:11:23
full isolation mode and turns on the
00:11:25
air regeneration installation, if it has one,
00:11:28
fill in the protective structure, it is
00:11:30
forbidden
00:11:31
first to smoke, make noise,
00:11:34
